    Skogen i våra hjärtan: Erfarenheter, emotionella band, värderingar och attityder till skog, natur och allemansrätten2015Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    En betydande del av Sveriges yta är täckt av skog och det finns många olika viljor finns rörande vilka värden skogen ska erbjuda. Syftet med studien var att undersöka människors erfarenheter, emotionella band och värderingar av skog och natur, samt attityder till naturresursutnyttjande och allemansrätt, inklusive samband dem emellan. Syftet var även att diskutera resultatet i förhållande till politiska mål rörande skog och natur. Totalt deltog 663 universitetsstudenter med medelåldern 24 år, varav 254 kvinnor och 401 män, i en enkätundersökning. Resultatet visade genom korrelationsanalys samband mellan samtliga variabler. Attityden att allemansrätten är viktig förklarades främst av starkare emotionella band och att oftare vistas i skogen. Attityden att allemansrätten bör begränsas förklarades av en högre värdering av virkesproduktion. Den var också vanligare hos de vars familj äger skog. Resultatet diskuterades i relation till miljömålsuppfyllelse och allemansrätten: emotionella band, som föds av erfarenheter, är incitament för agerande. För att uppfylla politiska mål bör emotioner beaktas och miljöer som ger förutsättning för erfarenhetsskapande erbjudas. Allemansrätten ger förutsättningar för dessa erfarenheter.

    Social media as the Cosmo Neighborhood2012Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The world has been transformed through the internet into a "global village",and social media platforms have possibly transformed the world into a larger neighborhood covering many regions of the world. Social networks such as Facebook and Twitter came into people’s lives through the Internet, growing daily at a large rate, and it has been proven that they are very popular. This study examines links between different phenomena through social media platforms (e.g. Facebook, Twitter, blogs, etc.). It is discusses cohesiveness, desire to belong, sense of community, beliefs and opinions about different forms of these phenomena in popular virtual platforms in correlation with trust in social media, criticism of information that is spread by these virtual platforms, and if people are influenced in consumer decision making. A questionnaire has been distributed to a convenient sample of 159 international and Swedish students in Sweden in October-November 2012 in both English and Swedish versions. According to the peoples’ answers, tendencies were observed such as to not trust the platforms, and also the information received, beliefs such that social media are "controlled", negative critique, but also an expression for a need for ‘membership’.

    Evaluation of Insight Training of Ambulance Drivers in Sweden Using DART: a New E-learning Tool2011Ingår i: Traffic Injury Prevention, ISSN 1538-9588, E-ISSN 1538-957X, Vol. 12, nr 6, s. 621-629Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: The aim of the study was to evaluate whether a new e-learning tool for insight training of ambulance drivers can have an effect on drivers’ driving behaviors, perceived driving competence, competence to assess risks, self-reflection, and safety attitudes.

    Methods: A quasi-experimental study design, with participants nonrandomly assigned into a control and intervention group, was used. The intervention group participated in the insight-training course and the control group did not. Both groups completed a self- and peer assessment online questionnaire before and after the training.

    Results: The main finding is that the ambulance drivers assessed themselves through the instruments after the training, with the e-learning tool Driver Access Recording Tool (DART), as safer drivers in the areas of speed adaptation, closing up, and overtaking. In the answers from the group-based evaluation, the ambulance drivers responded that they were more reflective/analytical, had increased their risk awareness, and had changed their driving behaviors.

    Conclusions: After insight training, the ambulance drivers in this study assessed themselves as safer drivers in several important areas, including speed adaptation, closing up, and overtaking. In future training of ambulance drivers there should be more focus on insight training instead of previous training focusing on maneuvering capabilities.

    INNOVATIVE TOOL-MODIFICATIONS AND TOOL SELECTIVITY IN NEW CALEDONIAN CROWS (CORVUS MONEDULOIDES)2012Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Tool-use and tool-manufacture are thought to require high cognitive skills and have been considered as an exclusive attribute to primates. Recent observations of New Caledonian crows (NCCs) challenge this assumption. In this study 13 NCCs were tested with two different tool production tasks. The NCC either had to straighten a hook or bend a stick to retrieve food from two different kinds of tree trunks. The result showed that 3/5 birds bent sticks and used them to retrieve food and 1/5 birds straightened hooks to retrieve food. The birds managed to solve both tasks but not the birds in the control group. This indicates that NCC's tool making is a flexible innovative act and not just an innate predisposition to bend flexible material. This finding is interesting given that recent studies on human children show that below 8 years of age children fail in similar innovative tool making tasks.

    Anchoring in inference and preference judgments2018Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    När vi fattar beslut behöver vi ofta göra avvägningar mellan olika alternativ och önskvärda egenskaper, så kallade trade-offs. Tidigare studier som har undersökt så kallad förankring (eng. ”anchoring bias”) har funnit att när ett referensvärde presenteras i samband med att en fråga ställs så kan det värdet påverka svaret på frågan. Förankringseffekten har visats förekomma i flera olika domäner. Däremot har tidigare studier framför allt studerat förankringseffekten genom att ställa inferensfrågor. Syftet med den här studien är därför att undersöka huruvida höga och låga förankringsvärden påverkar svaren inte bara på inferensfrågor utan också för subjektiva preferenser vid trade-offs. Ett datorbaserat frågeformulär användes för att samla in svaren på frågorna (N=90) i en mellangruppsdesign. Förankringsvärdet visade sig ha en inverkan på båda inferensfrågorna. För preferensfrågorna, var en av frågorna nära det valda tröskelvärdet (p < .05). För den andra preferensfrågan hade förankringsvärdet ingen signifikant effekt. Resultaten i den här studien tyder på att förankringseffekten var tydligare vid inferensbedömningar än vid bedömningar utifrån preferenser.

    Effects of Task Demands on Olfactory, Auditory, and Visual Event-Related Potentials Suggest Similar Top-Down Modulation Across Senses2018Ingår i: Chemical Senses, ISSN 0379-864X, E-ISSN 1464-3553, Vol. 43, nr 2, s. 129-134Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    A widely held view is that top-down modulation of sensory information relies on an amodal control network that acts through the thalamus to regulate incoming signals. Olfaction lacks a direct thalamic projection, which suggests that it may differ from other modalities in this regard. We investigated the late positive complex (LPC) amplitudes of event-related potentials (ERP) from 28 participants, elicited by intensity-matched olfactory, auditory and visual stimuli, during a condition of focused attention, a neutral condition, and a condition in which stimuli were to be actively ignored. Amplitudes were largest during the attend condition, lowest during the ignore condition, with the neutral condition in between. A Bayesian analysis resulted in strong evidence for similar effects of task across sensory modalities. We conclude that olfaction, despite its unique neural projections, does not differ from audition and vision in terms of task-dependent neural modulation of the LPC.

    Bilingualism and the Simon effect: A multimodal approach2015Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Tidigare forskning har studerat sambandet mellan tvåspråkighet och kognitiva förmågor. Vissa av dessa studiers resultat har visat att tvåspråkiga individer presterar bättre än enspråkiga i visuella Simon-uppgifter (dvs. de blir mindre distraherade av inkongruenta stimuli). Syftet med den aktuella studien är att se om man kan hitta en liknande effekt i Simon-uppgifter inom de taktila och auditiva sensoriska modaliteterna. I denna studie fick tvåspråkiga deltagare (36 universitetsstudenter) med olika kunskaper i sitt andraspråk utföra en Simon-uppgift där två intensiteter av vibrationer och två olika ljud används som relevanta stimuli. När resultaten var kontrollerade för arbetsminne så visades ingen negativ korrelation mellan varken tvåspråkig förmåga och Simon effekt eller daglig användning av det andra språket och Simon effekt. Utan att kontrollera för arbetsminne så fanns det en negativ korrelation för den taktila betingelsen och en positiv korrelation för den auditiva betingelsen mellan daglig användning av andra språk och Simon effekt. Slutsatsen dras att den statistiska kraften i denna studie lider av brist på deltagare och att om testet reproduceras med fler deltagare, med en större spridning i språkförmåga, så skulle en starkare effekt kunna ses. Det konkluderas även att fler tvärmodala studier behöver utföras innan slutsatser om generella kognitiva effekter av tvåspråkighet kan dras.

    Tuning in on motivation: Differences between non-musicians, amateurs, and professional musicians2019Ingår i: Psychology of Music, ISSN 0305-7356, E-ISSN 1741-3087Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The drive to learn and engage in music varies among individuals. Global motivation to do something can be intrinsic, for example, the joy and satisfaction in an activity. But motivation behind our action can also be extrinsic, such as the desire for fame, status or increased financial resources. The type of motivation probably influences to what degree individuals engage in musical activities. In this study, we examined the associations between the level of musical engagement and self-rated global motivation, factoring in age and sex, in a sample of 5,435 individuals. Musical engagement ranged from no music activity to amateurs and professional musicians. We found that intrinsic motivation increases with level of music activity and that motivation differs depending on sex, with females scoring higher on intrinsic motivation than males. Such differences may be considered in adjusting the forms of support offered to young musicians in music education. The phenomenon of motivation is complex, and we have highlighted areas that require further investigation, but this study has elucidated some differences in motivation types found in men and women, and between non-musicians, amateurs and professional musicians.

    Copenhagen Consensus statement 2019: physical activity and ageing2019Ingår i: British Journal of Sports Medicine, ISSN 0306-3674, E-ISSN 1473-0480Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    From 19th to 22nd November 2018, 26 researchers representing nine countries and a variety of academic disciplines met in Snekkersten, Denmark, to reach evidence-based consensus about physical activity and older adults. It was recognised that the term ‘older adults’ represents a highly heterogeneous population. It encompasses those that remain highly active and healthy throughout the life-course with a high intrinsic capacity to the very old and frail with low intrinsic capacity. The consensus is drawn from a wide range of research methodologies within epidemiology, medicine, physiology, neuroscience, psychology and sociology, recognising the strength and limitations of each of the methods. Much of the evidence presented in the statements is based on longitudinal associations from observational and randomised controlled intervention studies, as well as quantitative and qualitative social studies in relatively healthy community-dwelling older adults. Nevertheless, we also considered research with frail older adults and those with age-associated neurodegenerative diseases, such as Alzheimer’s and Parkinson’s disease, and in a few cases molecular and cellular outcome measures from animal studies. The consensus statements distinguish between physical activity and exercise. Physical activity is used as an umbrella term that includes both structured and unstructured forms of leisure, transport, domestic and work-related activities. Physical activity entails body movement that increases energy expenditure relative to rest, and is often characterised in terms of intensity from light, to moderate to vigorous. Exercise is defined as a subset of structured physical activities that are more specifically designed to improve cardiorespiratory fitness, cognitive function, flexibility balance, strength and/or power. This statement presents the consensus on the effects of physical activity on older adults’ fitness, health, cognitive functioning, functional capacity, engagement, motivation, psychological well-being and social inclusion. It also covers the consensus on physical activity implementation strategies. While it is recognised that adverse events can occur during exercise, the risk can be minimised by carefully choosing the type of activity undertaken and by consultation with the individual’s physician when warranted, for example, when the individual is frail, has a number of co-morbidities, or has exercise-related symptoms, such as chest pain, heart arrhythmia or dizziness. The consensus was obtained through an iterative process that began with the presentation of the state-of-the-science in each domain, followed by group and plenary discussions. Ultimately, the participants reached agreement on the 30-item consensus statements.

    Ledarskapets effekt på prestation och upplevd motivation - en experimentell studie2016Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Ledarskapet anses ha stor påverkan på individers motivation inom sin idrott. Ledarskap kan, inom ramarna för Self-Determination Theory (SDT), i stort sorteras i två olika stilar, autonomistödjande respektive kontrollerande ledarskap. I dagsläget finns en brist på experimentella studier som jämför dessa två ledarskapsstilars påverkan på motivation. Denna studie syftade till att i en isolerad miljö undersöka hur ett autonomistödjande respektive ett kontrollerande ledarskap har en påverkan på inre motivation och prestation. I studien ingick 37 deltagare som under 20 minuter fick utföra en bygguppgift med lego under en neutral, autonomistödjande eller kontrollerande ledarskapsstil. Resultatet visade att den kontrollerande ledarskapsstilen hade en viss negativ påverkan på motivation och att gruppen kontroll angav en lägre upplevd kompetens än gruppen autonomi.  Ingen av ledarskapsstilarna hade någon effekt på prestation. Vidare visade sig upplevd motivation ha ett signifikant samband med prestation på bygguppgiften.

    The Association Between Life Satisfaction and Affective Well-Being2019Ingår i: Journal of Economic Psychology, ISSN 0167-4870, E-ISSN 1872-7719, Vol. 73, s. 34-51Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We estimate the correlation between life satisfaction and affect—two conceptually distinct dimensions of subjective well-being. We propose a simple model that distinguishes between a stable and a transitory component of affect, and which also accounts for measurement error in self-reports of both variables, including current-mood bias effects on life satisfaction judgments. The model is estimated using momentarily measured well-being data, from an experience sampling survey that we conducted on a population sample of Swedes aged 18–50 (n=252). Our main estimates of the correlation between life satisfaction and long-run affective well-being range between 0.78 and 0.91, indicating a stronger convergence between these variables than many previous studies that do not account for measurement issues.

    Test-enhanced learning and the effects of individual differences in cognition and personality2016Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Test-enhanced learning refers to the well-established finding that repeated testing of a material will result in better recall of the material than repeated study will do, i.e. the testing effect. However, an under-researched aspect is how the effect of test-enhanced learning may vary due to individual differences in cognitive abilities and personality characteristics. The overarching purpose of this thesis is two-folded. First to evaluate the effects of test-enhanced learning. Second to investigate the relationship between working memory capacity, Need for Cognition, Grit, and test-enhanced learning. The within-subjects intervention consisted of 60 Swedish-Swahili word pairs. Subjects repeatedly studied 30 items and were repeatedly tested on 30 items. The effect of the intervention was measured immediately after training, 1 week later and 4 weeks later. The results showed that test-enhanced learning led to improved learning compared to restudy at all retention tests, replicating the testing effect. No association was found between either repeated testing or repeated study and WMC, NFC, or Grit.

    The Testing Effect and Its Relation to Working Memory Capacity and Personality Characteristics2017Ingår i: Journal of Cognitive Education and Psychology, ISSN 1945-8959, E-ISSN 1810-7621, Vol. 16, nr 3, s. 241-259Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Retrieval practice is known to lead to better retention of a to-be-learned material than restudy (i.e., the testing effect). However, few studies have investigated retrieval practice in relation to working memory capacity (WMC) and personality characteristics such as grittiness (Grit) and need for cognition (NFC). In two experiments, we examined retrieval practice and restudy of Swahili–Swedish word pairs in relation to individual differences in Grit and NFC. In Experiment 1, using a between-subjects design, a significant main effect of retention interval was qualified by a Group × Retention Interval interaction. However, there were no effects of Grit or NFC. In Experiment 2, a within-subjects design was used, and a measure of WMC was included. The analyses revealed a testing effect; but again, WMC, Grit, and NFC were not significantly associated with performance. These results indicate that retrieval practice levels out the playing field regarding WMC, NFC, and Grit.

    Second language proficiency and its effects on cognitive functions:: Relations between bilingualism and tactile and visual versions of the Simon task2015Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Bilinguals have repeatedly shown to have better results than monolinguals in non-verbal cognitive tasks that require inhibition of distracting stimuli. Evidence suggests that this enhanced performance is due to training effects of non domain specific executive functions, and that this gain in cognitive performance can contribute to a cognitive reserve in old age. One of the most frequently used methods when studying the relationship between second language proficiency and cognitive abilities is the Simon task in the visual sensory modality. The present study aimed to determine if the advantage found in the visual Simon task also could apply to a tactile Simon task. The sample consisted of 40 individuals aged 43 to 64 with different levels in their second language. An operational span test (OSPAN) was used to control for working memory capacity. No significant correlation was found between bilingualism and the Simon effect in either modality. Since the study has low statistical power and a small range in second language proficiency, it was concluded that further research investigating whether the bilingual advantage found in the visual Simon task can be found across modalities is necessary before any conclusions regarding a relationship between bilingualism and cognitive control can be made.

    Could musical mastery affect how attractive a person is rated as a prospective partner?2013Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Evolutionspsykologiska teorier förklarar och predicerar mänskligt beteende utifrån dess adaptiva värde. Vissa uppenbart icke-adaptiva beteenden, som människans hängivenhet till musik, kan förklaras som sexuell selektion av kostsamma signaler, eftersom det kräver tid och möda att lära sig bemästra ett instrument. Deltagare fick skatta bilder på personer av motsatt kön som påstods spela det musikstycke som hördes medan man tittade på varje bild. Musikutförandet var antingen av låg, medel, eller hög skicklighet, och ett bättre utförande förväntades ge högre skattningar av partnerattraktivitet eftersom det är mer kostsamt. Ingen effekt av musiken förelåg, förutom att kvinnorna skattade män som mindre attraktiva för ett längre förhållande när skicklighetsnivån var hög jämfört med när den var medelhög.

    The effects of sleep disturbances on memory2018Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Syftet med den här uppsatsen var att undersöka effekterna av sömnkvalitet och icke-restorativ sömn på både subjektiv och objektiv minnesfunktion. Data togs från en longitudinell studie i Umeå och bestod av 956 deltagare. Efter att ha exkluderar personer under 65 år och kontrollerat för saknade värden bestod den återstående gruppen av 468 män (n=185) och kvinnor (n=204). Multipla regressionsmodeller utfördes för att analysera om sömnkvalitetsstörningar och icke-restorativ sömn kunde predicera subjektiv och objektiv minnesfunktion. Resultaten visade att både höga värden av sömnkvalitetsstörningar och icke-restorativ sömn predicerade subjektiva minnesbesvär. Däremot predicerade ingen av sömnindexen objektiv minnesfunktion. Framtida studier bör därför undersöka den longitudinella effekten av sömnstörningar på objektiv minnesfunktion, samt effekten av sömnstörningar på episodiskt minne.

    Swedish student perceptions of achievement practices: the role of intelligence2018Ingår i: Intelligence, ISSN 0160-2896, E-ISSN 1873-7935, Vol. 69, s. 94-103Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The role of intelligence and motivational constructs in school achievement is well attested. Beliefs and attitudes about assessment (including classroom assessment, homework and tests) can be adaptive within a self-regulation of learning framework. However, the role of intelligence upon the student and parent coping with school assessment practices is less well known. This paper examines responses of Swedish Grade 6 (modal age 13) students (N = 4749) participating in the Education Through Follow-up (ETF) project to four cognitive tests and survey items concerning achievement demands. Their responses were integrated with parent perceptions of grading and school pressure. Robust factors for intelligence, student perceptions, and parental perceptions were found and introduced into a structural equation model with intelligence as the predictor. The well-fitting SEM model showed that intelligence had statistically significant predictions on all four student and three parent perceptions factors, of which two predicted student factors. However, only one prediction was substantive; intelligence on coping with school demands (beta = 0.48). Although not allowing for causal inference, the results support the claim that general cognitive abilities act as a predictor of self-regulating capability of coping with school demands.

    Ready for Transfer to Adult Care?: A Triadic Evaluation of Transition Readiness in Adolescents With Congenital Heart Disease and Their Parents2019Ingår i: Journal of Family Nursing, ISSN 1074-8407, E-ISSN 1552-549X, artikel-id UNSP 1074840719864255Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Transfer to adult care for adolescents with chronic conditions ought to be determined by transition readiness. The aims of this study were (a) to describe the level of readiness for transition in adolescents with congenital heart disease, (b) to compare adolescents' assessment of transition readiness with their parents' assessments, and (c) to study potential correlates of transition readiness. A total of 157 triads of adolescents aged 14 to 18 years and their parents completed the Readiness for Transition Questionnaire. Adolescents scored higher on overall readiness than their parents. Multivariable analyses revealed that higher levels of adolescents' overall readiness were associated with a less threatening view of the illness, a higher level of empowerment, and with higher mothers' and fathers' overall readiness scores. Adolescents' responsibility scores were positively associated with age and parental adolescent responsibility scores. Parental involvement scores were negatively associated with adolescents' age and positively with the mothers' parental involvement scores. By using a triadic evaluation, the results of the present study significantly extend what is currently known about this population.

    Psychometric studies of the Swedish version of the Adolescent Drug Abuse Diagnosis (ADAD) instrument2011Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    This thesis describes studies into the psychometric properties of a Swedish language version of the Adolescent Drug Abuse Diagnosis (ADAD) instrument. The psychometric properties of this instrument have been examined in two previous studies: an American study was conducted by the developers of the interview, Friedman and Utada (1989), and a Swiss study was undertaken by Bolognini et al. (2001). The American and the French (as used in the Swiss study) versions of ADAD exhibit good validity and reliability, in the form of both interrater reliability and the internal consistency of the composite scores. Study I evaluated the psychometric properties of the Swedish version of the ADAD interview in normal adolescents and adolescents with antisocial problems. It was found that the instrument has good interrater reliability, that the composite scores exhibit moderate internal consistency, and that the concept validity was acceptable and similar to that of the American and Swiss versions. The results also showed that the problem areas of ADAD produced meaningful correlations. The interviewer ratings, the adolescent’s ratings and the composite scores were compared and discussed. Some problems concerning the composite scores were discovered and will need to be analyzed in future studies. Study II investigated the utility and problems associated with the composite scores in the ADAD within and between normal adolescents and adolescents with antisocial problems. When comparing interviewer severity ratings and composite scores within the two groups, the composite scores were found to behave differently to the interviewer ratings. For normal adolescents, the composite scores are generally higher than the interviewer ratings, but for the adolescents with antisocial problems the reverse is true. The interviewer severity ratings seem to be the most appropriate outcome when the objective is to separate antisocial and normal groups of adolescents from each other. The difference between the two groups is smaller as measured by composite scores. The composite scores appear to function as viable indicators of current problems in all areas except for Medical and Alcohol problem area. The critical items within the Medical and Alcohol composite scores are explored and discussed.  Study III investigated the concurrent and predictive validity of the ADAD Psychological status and problem area. Concurrent validity was demonstrated by significant correlations between the ADAD, Youth Self Report (YSR) and Beck Depression Inventory (BDI) scores. The predictive validity of this problem area of the ADAD was tested by exploring its correlations with the YSR, BDI, and DICA problem ratings; moderate correlations were observed, suggesting that in clinical practice, the ADAD Psychological status and problem area may be a useful tool for the assessment and measurement of current psychological problems. The utility obtained by making decisions using the test is substantial. Overall, the results of these studies indicate that the Swedish version of ADAD appears to be a psychometrically good instrument for assessing the severity of adolescents’ problems and their need for treatment, but there are some problems with the Medical and Alcohol composite scores.

    Concurrent and predictive validity of the Adolescent Drug Abuse Diagnosis (ADAD)2012Ingår i: Open Psychology Journal, ISSN 1874-3501, Vol. 5, s. 20-30Artikel i tidskrift (Övrigt vetenskapligt)
    Abstract [en]

    The concurrent and predictive validity of the Adolescent Drug Abuse Diagnosis (ADAD) in the Psychological status and problem area was examined for two adolescent groups: a non-clinical population of 121 Swedish adolescents (62 girls and 59 boys) aged 15 to17 years and a clinical population of 31 adolescents (14 girls and 17 boys) aged 12 to 19 years detained in special youth homes. Concurrent validity was demonstrated by significant correlations between the ADAD, Youth Self Report (YSR) and Beck Depression Inventory (BDI) scores. Findings regarding the predictive validity of ADAD show moderate associations with YSR, BDI and DICA problem ratings. The findings suggest that for clinical practice the ADAD Psychological status and problem area may be an appropriate assessment tool for measurement of current psychological problems. The utility obtained by making decisions using the test is substantial.

    Are normative probabilty judgments a "system two"-operation?2017Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Tidigare forskning om mänskligt beslutsfattande och bedömningar har i experiment påvisat systematiska och förutsägbara bias. Ett exempel på detta är tendensen att intuitivt gå emot konjuktionsregeln- en enkel regel gällande sannolikhet. Detta illustrerades väl i det berömda Linda- problemet (Tversky & Kahneman, 1983). Enligt två-systemsteorin (Kahneman, 2011) om problemlösning, uppstår bedömningsfel såsom konjuktionsfelet när människor inte använder sig av analytiskt tänkande och istället förlitar sig för mycket på sin intuition. Två-systemsteorin menar att de kognitiva processer som ligger till grund för våra intuitiva impulser och vårt medvetna resonerande utgör två olika aktörer i vårt tänkande- system 1 och system 2- och att det intuitiva system 1 inte kan beräkna sannolikheter. Processer som betecknas som tillhörande system 1 är enligt två-systemsteorin snabba medan system 2 föreställs vara ett långsamt system. I denna studie testades antagandet om tidsåtgång för de två systemen i en inomgruppsdesign genom att jämföra responstider mellan bedömningar där konjunktionsfelet begåtts och bedömningar där det inte begåtts. Resultaten visar att korrekta sannolikhetsbedömningar inte resulterar i långsammare responstider. Detta indikerar att det inte tycks vara mer tidskrävande att göra riktiga sannolikhetsbedömningar, vilket motsäger två-systemsteorins antagande om snabbt och långsamt processande.

    Hypertension, Infection and Inflammation and their Effects on Memory and Visuospatial Skills in Ageing2016Självständigt arbete på avancerad nivå (magisterexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Högt blodtryck har associerats med minnesnedsättning men den exakta mekanismen hur ett samband kan förstås är dock oklar. Infektioner har visat sig ge systematiska inflammationer och har också satts i samband med vissa kardiovaskulära förändringar i hjärnan, så kallade mikroblödningar, vilka i sig har associerats med ökad risk för kognitive nedsättning i hög ålder. Denna uppsats syftar till att undersöka om blodtryck och infektion (självrapporterad infektion samt infektion indirekt mätt genom sänkereaktion) kan relateras till episodiskt och semantisk minne samt visuospatial förmåga i Betula studien, som är en svensk longitudinell populationsbaserad studie. Resultatet visade att varken högt blodtryck (över 140 mm Hg systoliskt eller 90 mm Hg diastoliskt), hög sänkereaktion (de 33 % med högst värde jämfört med de 33 % med lägst värde) eller självrapporterad infektion hade någon signifikant effekt för episodiskt minne, semantiskt minne eller visuospatial förmåga. Några möjliga förklaringar till detta resultat utvecklas i diskussionen.

    Train your brain: updating, transfer, and neural changes2009Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    An initial aim of this thesis was to determine whether training of a specific executive function (updating) produces improvements in performance on trained and transfer tasks, and whether the effects are maintained over time. Neural systems underlying training and transfer effects were also investigated and one question considered is whether transfer depends on general or specific neural overlap between training and transfer tasks. An additional aim was to identify how individual differences in executive functioning are mapped to functional brain changes. In Study I, significant training-related changes in performance on the letter memory criterion task were found in both young and older adults after 5 weeks of updating training. Transfer to a 3-back test of updating was also demonstrated in the young adults. Functional Magnetic Resonance Imaging (fMRI) revealed overlapping activity in letter memory and 3-back tasks in fronto-parietal areas and striatum pre-training, and a joint training-related activity increase for the tasks in a striatal region. No transfer was observed to a task (Stroop) that engaged fronto-parietal areas, but not the striatal region and updating per se. Moreover, age-related striatal changes imposed constraints on transfer. In Study II, additional transfer tasks and a test of long-term maintenance were included. Results revealed that training-related gains in performance were maintained 18 months post-training in both young and older adults, whereas transfer effects were limited to tasks requiring updating and restricted to young participants. In Study III, analyses of brain activity and performance during n-back (1/2/3-back) were executed. This task enables manipulation of executive demand, which permits examination of how individual differences in executive functioning can be mapped to functional brain changes. Relative to a young high-

    performing group, capacity constraints in executive functioning were apparent between 1–2-back for the elderly participants and between 2–3-back for a young low-performing group. Capacity constraints in neural activity followed this pattern by showing a monotonically increasing response in the parietal cortex and the thalamus for young high performers, whereas activity levelled off at 1-back for elderly performers and at 2-back for young low performers. The response in the dorsal frontal cortex followed a similar pattern. Together, these findings indicate that fronto-parietal as well as sub-cortical areas are important for individual differences in executive functioning, training of updating and transfer effects.

    Abstract [en]

    Chemical intolerance (CI) is a term used to describe a condition in which the sufferer experiences a complex array of recurrent unspecific symptoms attributed to low-level chemical exposure that most people regard as unproblematic. Severe CI constitutes the distinguishing feature of multiple chemical sensitivity (MCS). The symptoms reported by CI subjects are manifold, involving symptoms from multiple organs systems. In severe cases of CI, the condition can cause considerable life-style limitations with severe social, occupational and economic consequences. As no diagnostic tools for CI are available, the presence of the condition can only be established in accordance to criteria definitions. Numerous modes of action have been suggested to explain CI, with the most commonly discussed theories involving the immune system, central nervous system, olfactory and respiratory systems as well as altered metabolic capacity, behavioral conditioning and emotional regulation. However, in spite of more than 50 years of research, there is still a great deal of uncertainties regarding the event(s) and underlying mechanism( s) behind symptom elicitation. As a result, patients are often misdiagnosed or offered health care solutions with limited or no effect, and they experience being met with mistrust and doubt by health care professionals, the social care system and by friends and relatives. Evidence-based treatment options are currently unavailable, however, a person-centered care model based on a multidisciplinary treatment approach and individualized care plans have shown promising results. With this in mind, further research studies and health care solutions should be based on a multifactorial and interdisciplinary approach.

    Better out than in: The influence of anger regulation on physical performance2010Ingår i: Personality and Individual Differences, ISSN 0191-8869, E-ISSN 1873-3549, Vol. 49, nr 5, s. 457-460Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We examined the influence of individual differences in anger regulation as potential moderators of the anger–performance relationship. Extending Lazarus’s (1991, 2000a) cognitive–motivational–relational theory of emotion, we investigated the influence of trait anger and the anger regulation styles of anger-in and anger-out on the performance of a physical task. As hypothesized, trait anger and anger-out were positively associated with anger-derived performance enhancement on a peak force task; anger-in significantly inhibited the trait anger–performance relationship. Results are discussed in relation to Lazarus’s cognitive–motivational–relational theory and future research directions are offered.

    Kinematic characteristics of second‐order motor planning and performance in 6‐ and 10‐year‐old children and adults: Effects of age and task constraints2019Ingår i: Developmental Psychobiology, ISSN 0012-1630, E-ISSN 1098-2302Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study explored age‐related differences in motor planning as expressed in arm‐hand kinematics during a sequential peg moving task with varying demands on goal insertion complexity (second‐order planning). The peg was a vertical cylinder with either a circular or semicircular base. The task was to transport the peg between two positions and rotate it various amounts horizontally before fitting into its final position. The amount of rotation required was either 0°, 90°, 180°, or −90°. The reaching for the peg, the displacement of it, and the way the rotation was accomplished was analyzed. Assessments of end state comfort, goal interpretation errors, and type of grip used were also included. Participants were two groups of typically developing children, one younger (Mage = 6.7 years) and one older (Mage = 10.3 years), and one adult group (Mage = 34.9 years). The children, particularly 6‐year‐olds, displayed less efficient prehensile movement organization than adults. Related to less efficient motor planning, 6‐year‐olds, mainly, had shorter reach‐to‐grasp onset latencies, higher velocities, and shorter time to peak velocities, and longer grasp durations than adults. Importantly, the adults rotated the peg during transport. In contrast, the children made corrective rotations after the hand had arrived at the goal.

    Developmental progression and side specialization in upper-limb movements from 4 to 8 years in children born preterm and fullterm2018Ingår i: Developmental Neuropsychology, ISSN 8756-5641, E-ISSN 1532-6942, Vol. 43, nr 3, s. 219-234Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study investigated developmental changes and differences in upper-limb movement organization from 4 to 8 years of age in children born preterm (PT) and fullterm (FT). Kinematic recordings of precision-demanding unimanual movements and lateral assessments were carried out in 37 children (18 PT). All children, particularly children born PT, displayed considerable gain in movement kinematics. Contrary to controls, children born PT displayed persistently less-evident side preference. Gestational age (GA) contributed significantly to kinematic differences shown, with larger upper-limb deviances in the lowest GAs, in agreement with cross-sectional findings of altered hemispheric connections and delayed side-specialization among children born very PT.

    Neural correlates of selective attention during working memory in presence of distraction2019Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Att hålla information i arbetsminnet under korta tidsintervaller kräver ett fokus på målinriktad hantering och filtrering av irrelevant information. Selektiv uppmärksamhet har indikerats som en kritisk komponent för lyckad arbetsminnesinkodning och underhåll av information på kort sikt. Spatial selektiv uppmärksamhet medierar arbetsminnets hantering av målinriktad information och inhiberar samtidigt distraktioner. Detta är ett resultat av genljudande toppstyrda signaler i ett frontoparietalt neuralt nätverk som interagerar med sensoriska områden. Denna fMRI-studie använde en s.k. fördröjd match-to-sample-uppgift för att utforska nivån av bidragande inom nätverket till faserna för arbetsminnesinkodning av information och underhåll, genom att presentera relevanta och distraherande stimuli samtidigt. Målet med studien var att testa för ökad aktivitet i det frontoparietala nätverket med närvaro av distraktion jämfört med endast relevant mål under inkodnings- och underhållsfaserna. Genom att undersöka aktivering kontralateral gentemot målet undersökte vi därutöver hur korttidsrepresentationer kunde påverka fördelning av uppmärksamhet. Utvärdering av testresultaten visade att deltagarnas prestation påverkades negativt med närvaro av irrelevant information. Inga belägg för toppstyrd modulering kunde emellertid finnas i envariabla analyser av fMRI-data, och ej heller för inkodnings- eller underhålsfaserna. Så kallade whole-brain och ROI-analyser användes för att söka efter aktivitet kontralateralt till målpositionering, men fann inga länkar till det toppstyrda nätverket eller uppmärksamhetsfördelning. Denna studie tillhandahåller inga definitiva belägg för selektiv uppmärksahetsmodulering under arbetsminnesbearbetning, vilket indikerar ett behov av större manipuleringsbörda i framtida försök.

    Personality and mental health: An investigation of South African police trainees2011Ingår i: Psychological Reports, ISSN 0033-2941, E-ISSN 1558-691X, ISSN 0033-2941, Vol. 108, nr 1, s. 301-316Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The relationship between personality and mental health was investigated in one cohort of police trainees at a South African police academy (1,145 police recruits; 648 men, 497 women). Male trainees reported less somatisation, depression, anxiety, and phobic anxiety symptoms and lower harm avoidance as well as higher persistence than female trainees. A cluster analysis based on the personality scores was used to identify three clusters with personality profiles characterized as Vulnerable, Healthy, and Intermediate profiles. Sociodemographic variables and temperament and character domain scores contributed separately and differentially to the explanation of variance in mental health symptom scores. Selection tools should be developed to identify vulnerable individuals in terms of personality characteristics during selection and prior to training, to prevent later problems with stress reactions. Additional training modules focusing on coping skills could possibly reduce vulnerability to stress in some trainees.

    Sex differences on Raven's Standard Progressive Matrices within Saudi Arabia and across the Arab world: females' advantage decreases from childhood to adolescence2018Ingår i: Personality and Individual Differences, ISSN 0191-8869, E-ISSN 1873-3549, Vol. 134, s. 66-70Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Sex differences in intelligence are of great importance with regard to understanding intelligence's underlying evolutionary forces. Previous research in this area has had a strong focus on Western countries and data across developmental stages are fragmented. Here, we present new data on Raven's Standard Progressive Matrices from three samples in Saudi Arabia, and combine these with nine previously published studies from other Arab countries, which also provide data for each year of age. We specifically consider Lynn's developmental theory of sex differences in intelligence, whereby a female advantage becomes pronounced due to earlier average puberty and then decreases as males enter puberty. The estimates for each age do not differ significantly from zero, and very few from each other, apparently due to large heterogeneity across studies. Nevertheless, the age trend is largely consistent with Lynn's model. Moreover, its specific predictions are seemingly borne out in many individual countries. Plausible explanations for incongruities in Sudan, Libya, Yemen and Saudi Arabia are also examined.

    Why do high IQ societies differ in intellectual achievement?: The role of schizophrenia and left-handedness in per capita scientific publications and Nobel prizes2019Ingår i: The Journal of creative behavior, ISSN 0022-0175, E-ISSN 2162-6057Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Previous research has attempted to understand why countries with relatively favorable conditions and high estimated average IQs (such as Finland and Japan) have a relatively low per capita number of scientific Nobel prizes. In the present study, we examine whether there is a relationship between national schizophrenia and left‐handedness prevalence, on the one hand, and per capita scientific and literary achievement, on the other hand, in countries with IQ estimates of at least 90. We found that per capita science and literature Nobel prizes and scientific publications are strongly negatively associated with schizophrenia and strongly positively correlated with left‐handedness. There also was a very pronounced negative correlation between schizophrenia rate and left‐handedness rate. These results suggest that genius can be regarded as a combination of very high IQ, aspects of high‐functioning autism (specifically low empathy) plus relatively low impulse control, consistent with observations of intellectually outstanding individuals, and the fact that schizophrenia appears to constitute the opposite pole of these aspects of autism spectrum. We posit differences in androgen levels as a possible underlying explanation for these findings.

    Aspects of modern health worries as predictors of development of anxiety and depression symptoms2018Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Oro kopplad till de negativa hälsoaspekterna av ett modernt liv (Modern hälsooro, MHO) har ökat under de senaste årtiondena, men fenomenet är inte helt klarlagt. Den här studien undersökte associativa och prediktiva samband mellan olika typer av modern hälsooro och symtom av ångesttillstånd samt depression i ett urval i Västerbottens län (n=2223). De fyra subskalorna av Modern Health Worries Scale (MHWS) användes för att undersöka de olika typerna av MHO medan Hospital Anxiety and Depression Scale användes för att mäta symtom av ångesttillstånd och depression. Korrelationsanalyser baserat på Spearmans korrelationskoefficient samt hierarkiska, multipla regressionsanalyser användes för att mäta graden av association respektive prediktion.  Resultatet visar att de olika subskalorna var associerade med symtom av både depression och ångesttillstånd i olika hög grad. Dock predicerade inte MHO en signifikant förändring av varken ångest- eller depressionssymtom. Detta tyder på att ett enskilt beaktande av subskalorna ger en mer nyanserad bild av en individs upplevelse av MHO jämfört med om endast totalpoängen på MHWS beaktas. Resultatet föreslår vidare att en upplevelse av MHO inte orsakar en ökning av varken ångest eller depressionssymtom.

    Subjective olfactory loss in older adults concurs with long-term odor identification decline2019Ingår i: Chemical Senses, ISSN 0379-864X, E-ISSN 1464-3553, Vol. 44, nr 2, s. 105-112Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Olfactory impairments may provide early indications of future health outcomes in older adults. Thus, an important question concerns whether these impairments can be self-assessed. Previous findings of cross-sectional studies indicate low correlations between self-reported olfactory function and objective olfactory performance. On the other hand, subjective olfactory impairments predict future dementia and mortality in longitudinal settings. No previous study has assessed the relationship between subjectively and objectively measured decline in olfaction over time. Based on data for 903 older adults derived from the Betula Study, a Swedish population-based prospective study, we tested whether rate-of-change in odor identification could be predicted from subjective olfactory decline over a time span of 10 years during which subjective and objective odor functions were assessed on 2 or 3 test occasions. Indeed, we found that participants who experienced subjective olfactory decline over the study period also had significantly steeper rates of decline in odor identification, even after adjusting for demographic, cognitive, and genetic factors that previously have been associated with performance in odor identification. This association was, however, not present in a subsample with baseline cognitive impairment. We interpret these results as evidence that when asked about whether they have an olfactory impairment or not, older persons are assessing intraindividual olfactory changes, rather than interindividual differences. Our results indicate that subjective olfactory loss reflects objective olfactory decline in cognitively intact older adults. This association might be harnessed to predict health outcomes and highlights the need to develop effective olfactory self-assessments.

    Evaluating the effect of the Sensavis visual learning tool on student performance in a Swedish elementary school2017Självständigt arbete på avancerad nivå (magisterexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Enligt “dual coding theory” hjälper det att kombinera flera sätt att inta information (t.ex. visuellt, verbalt) inom lärandet. Presentation av information genom 3D-bilder och 3D-animationer verkar förbättra prestation bland elever, men resultaten är inkonsekventa i flera studier. Denna studie undersökte effekten av ett visuellt verktyg från Sensavis, en  pedagogisk programvara med 3D-animationer, på prestation inom kemi bland elever i en svensk grundskola. Trettiosju elever från årskurs 7 och 9 använde en 3D-animering om kemisk bindning förutom föreläsningar, medan nitton elever i årskurs 8 fick traditionell undervisning. ANCOVA-resultat som kontrollerade för ålder och kemibetyg visade att kontrollgruppen presterade bättre än bägge experimentgrupperna. Dessa resultat tyder på att Sensavis-verktyget inte hade en positiv effekt på lärande i kemi jämfört med traditionell undervisning. Tolkningen av resultaten presenteras i diskussion.

    Utvärdering av KONTAKT i en klinisk verksamhet: Förändringar i sociala färdigheter hos en grupp 15-åriga pojkar med autismspektrumtillstånd2015Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Brist på sociala färdigheter är en svårighet som kopplas till autismspektrumtillstånd (AST). Många olika interventioner har föreslagits för att förbättra sociala färdigheter för barn och ungdomar med AST med blandade resultat. KONTAKT är en relativt ny manualbaserad metod som fått ökat intresse inom kliniska verksamheter och forskning. Syftet med studien var att utvärdera kort- och långsiktiga behandlingseffekter av KONTAKT. Studien genomfördes vid en Barn- och ungdomshabilitering som en klinisk effektstudie utan kontrollgrupp. Fem pojkar i 15-årsåldern, 11 föräldrar samt ett antal lärare till var och en av pojkarna deltog i studien. Data samlades in genom enkäter och semistrukturerade intervjuer. De kvantitativa resultaten visade huvudsakligen inte på någon effekt förutom en viss positiv förändring avseende föräldrarnas upplevelse av ungdomarnas sociala färdigheter, medan de kvalitativa resultaten skulle kunna antyda en mer positiv förändring. Sammanfattningsvis skulle KONTAKT kunna vara en användbar metod för att förbättra sociala färdigheter. Resultatet bör dock tolkas med försiktighet med tanke på urvalsstorleken, frånvaron av kontrollgrupp samt databortfall. Vidare forskning med randomiserade kontrollgrupper behövs för att kunna säkerställa effekten av KONTAKT.

    Effekter av kortvarig fysisk aktivitet på kognitiva förmågor2019Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Korta träningspass har visat sig förbättra elevers skolprestation. Vidare har också vissa kognitiva förmågor visat sig förbättra skolprestation. Denna studies syfte var därför att se om korta träningspass kan förbättra vissa kognitiva förmågor och huruvida dessa förmågor då skulle fungera som mediatorvariablermellan träning och skolprestation. Trettio deltagare delades slumpmässigt in i en kontrollgrupp som fick se en musikvideo (n=15) och en experimentgrupp som fick gå upp och ner för en step up-bräda (n=15). Kognitiv skiftning, episodiskt minne och mentalt tempo testades i båda grupper, före och efter interventionen. Resultatet visade inte på någon signifikant effekt på någon kognitiv förmåga. Detta kan bero på det låga antalet deltagare, då effekter av liknande studier ofta är små.

    Components and Drivers of Long-term Risk Communication: Exploring the Within- Communicator, Relational, and Content Dimensions in the Swedish Forest Context2017Ingår i: Organization & environment, ISSN 1086-0266, E-ISSN 1552-7417, Vol. 30, nr 2, s. 162-179Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Risk communication is important for a sustainable management of natural resources. Even though risk management is ideally ongoing, studies of long-term risk communication from the perspective of the communicator are lacking. This case study examined the preparation and implementation of forest risk communication in Sweden. Interviews were conducted with advisors at the Swedish Forest Agency, responsible for providing information to forest owners and professional foresters dealing with risks damaging the forest (e.g., storms and forest management damaging ecological values). The communicator’s perspective was analyzed based on a conceptual framework describing risk communication by means of the components: within communicator, relational, and content. Potential drivers of the preparation and implementation of risk communication in this context, intersecting the three components, included the policy and regulatory framework, the management of the agency, the location of the agency, and the balancing of different interests.

    General Public Acceptance of Forest Risk Management Strategies in Sweden: Comparing Three Approaches to Acceptability2018Ingår i: Environment and Behavior, ISSN 0013-9165, E-ISSN 1552-390X, Vol. 50, nr 2, s. 159-186Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Global change calls for more active approaches to forest risk management. To avoid unforeseen backlashes, it is necessary to examine the general public's acceptance of the risk management strategies. By drawing on different theoretical approaches (threat and prevention, performance evaluations, and forest cognitions), the present study examines predictors of acceptability in the general public in three counties in Sweden (N = 1,026). As expected, appraisals of threat mediated the effect of threat awareness on belief in risk prevention, and when examining performance evaluations, trust in responsible actors influenced acceptability via procedural satisfaction. However, the threat and prevention approach and the performance evaluation approach only explained low levels of the variance in acceptability of the examined strategies. Nevertheless, stronger ecological forest values, and favoring broadleaved forests, were found to be important to the acceptability of proactively implementing a more diverse forest to meet the expected challenges associated with global climate change.

    Longitudinal effects of bilingualism on dual-tasking2017Ingår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 12, nr 12, artikel-id e0189299Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    An ongoing debate surrounds whether bilinguals outperform monolinguals in tests of executive processing. The aim of this study was to investigate if there are long-term (10 year) bilingual advantages in executive processing, as indexed by dual-task performance, in a sample that were 40-65 years at baseline. The bilingual (n = 24) and monolingual (n = 24) participants were matched on age, sex, education, fluid intelligence, and study sample. Participants performed free-recall for a 12-item list in three dual-task settings wherein they sorted cards either during encoding, retrieval, or during both encoding and retrieval of the word-list. Free recall without card sorting was used as a reference to compute dual-task costs. The results showed that bilinguals significantly outperformed monolinguals when they performed card-sorting during both encoding and retrieval of the word-list, the condition that presumably placed the highest demands on executive functioning. However, dual-task costs increased over time for bilinguals relative to monolinguals, a finding that is possibly influenced by retirement age and limited use of second language in the bilingual group.

    Reading Habits Among Older Adults in Relation to Level and 15-Year Changes in Verbal Fluency and Episodic Recall2018Ingår i: Frontiers in Psychology, ISSN 1664-1078, E-ISSN 1664-1078, Vol. 9, artikel-id 1872Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The main objective of this study was to investigate reading habits in older adults in relation to level and 15-year changes in verbal fluency and episodic recall. We examined a sample of 1157 participants (55 years at baseline) up to 15 years after the baseline assessment using latent growth curve modeling of cognitive measures with baseline reading frequency (books, weekly magazines) as a predictor of cognitive level (intercept) and rate of change (slope). Subgroup analyses were performed to investigate the role of an early adult g factor in the association between reading habits and cognitive ability in midlife. Frequent reading of books, but not of magazines, was associated with higher levels of verbal fluency and recall but unrelated to rate of longitudinal decline. Subgroup analyses indicated that the g factor in early adulthood predicted reading and cognitive level in midlife and this factor removed the current association between reading habits and level of cognitive ability (both cognitive factors). The results indicate an enduring relationship between book reading and level of cognitive ability across the adult life span and provide little support of the hypothesis that frequent reading protects against latelife cognitive decline. The extent to which book reading promotes cognitive functioning in childhood/youth remains to be demonstrated. Intervention studies may be useful in this regard.

    Open Relationship Prevalence, Characteristics, and Correlates in a Nationally Representative Sample of Canadian Adults2019Ingår i: Journal of Sex Research, ISSN 0022-4499, E-ISSN 1559-8519, Vol. 56, nr 6, s. 695-704Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Open relationships are those in which individuals agree to participate in sexual and/or emotional and romantic interactions with more than one partner. Accurate estimates of the prevalence of open relationships, based on representative, unbiased samples, are few, and there are none from outside of the United States. We present findings from a nationally representative sample of 2,003 Canadian adults, administered in 2017 via an online questionnaire. Overall, 2.4% of all participants, and 4.0% of those currently in a relationship, reported currently being in an open relationship. One-fifth of participants reported prior engagement in an open relationship, and 12% reported open as their ideal relationship type. Men, compared with women, were more likely to report prior open relationship engagement and to identify open as their ideal relationship type. Younger participants were more likely both to engage in and to prefer open relationships. Relationship satisfaction did not differ significantly between monogamous and open relationships. Having a match between one's actual relationship type and one's preferred relationship type was associated with greater relationship satisfaction. Findings suggest that, while currently only a small proportion of the population is in an open relationship, interest in open relationships is higher, particularly among younger adults, and open appears to be a viable and important relationship type.

    PÅVERKAN AV ORGANISATIONSFÖRÄNDRING, ROLLTYDLIGHET OCH LEDARSTÖD PÅ ÖVERENGAGEMANG2018Självständigt arbete på avancerad nivå (magisterexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Forskning visar att den arbetsrelaterade ohälsan ökar i Sverige. För sysselsatta inom äldreomsorgen finns studier som visar att sjukfrånvaro främst är kopplad till sociala och organisatoriska faktorer på arbetsplatsen. Teorin om Effort-Reward-Imbalance beskriver överengagemang (over-commitment) som ett personbundet beteende med överdrivet engagemang som kan utgöra en riskfaktor för arbetsrelaterad ohälsa. Syftet med studien är att undersöka i vilken utsträckning organisationsförändring, rolltydlighet och ledarstöd predicerar överengagemang. Vår studie bygger på ett longitudinellt projekt, där 185 anställda inom äldreomsorgen från norra Sverige ingår. Deltagarna representeras övervägande av kvinnliga undersköterskor och vårdbiträden med i huvudsak tillsvidareanställning eller långtidsvikariat. Materialet analyserades i det statistiska programmet IBM SPSS Statistics Version 25, genom korrelationer och hierarkisk regression. Resultatet visar att upplevelse av organisationsförändringar och brister i rolltydlighet är relaterat till överengagemang. Ledarstöd har ett signifikant samband med överengagemang tillsammans med organisationsförändring. Däremot visar ledarstöd tillsammans med organisationsförändring och rolltydlighet ingen ytterligare förklaring till variansen för graden av överengagemang.

    Exploring the effect of emotionally induced arousal on curiosity2018Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Curiosity can be defined as a drive to engage in exploratory behaviors and has been associated with an increased state of arousal (Berlyne, 1954). Exploratory behaviors, such as feedback requests, are associated with an information gain and the reduction of uncertainty. Although previous research has demonstrated the effects of emotions on the value of information gain (Marvin & Shohamy, 2016), and that the manipulation of arousal affected confidence (Allen et al., 2016) suggesting uncertainty can be affected independent of task difficulty, no previous study independently manipulated arousal to test its effect on curiosity. Given the effects of curiosity on motivation and learning, understanding how arousal influence curiosity would be beneficial for applications in fields such as education. In the present study, we hypothesized that emotionally-induced arousal has an impact on curiosity by influencing uncertainty and the value of information gain. A sample of 17 students were presented with arousing supraliminal emotional cues prior to rating confidence about their answers to trivia questions and deciding on feedback choices. Feedback requests were associated with a time delay, in a way that participants were required to trade off time for information. Results showed that uncertainty levels did not reliably predict feedback choices. Further analyses failed to demonstrate an effect of arousal on feedback choices. Finally, the pupillary response to events suggested that arousal levels did not differ significantly across conditions. Results can be due to the small sample or the test sensitivity. Possible improvements to the experimental paradigm are discussed, and directions for future research are considered.

    Events and children's sense of time: a perspective on the origins of everyday time-keeping2015Ingår i: Frontiers in Psychology, ISSN 1664-1078, E-ISSN 1664-1078, Vol. 6, artikel-id 259Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In this article I discuss abstract or pure time versus the content of time, (i.e., events, activities, and other goings-on). Or, more specifically, the utility of these two sorts of time in time-keeping or temporal organization. It is often assumed that abstract, uniform, and objective time is a universal physical entity out there, which humans may perceive of. However, this sort of evenly flowing time was only recently introduced to the human community, together with the mechanical clock. Before the introduction of mechanical clock-time, there were only events available to denote the extent of time. Events defined time, unlike the way time may define events in our present day culture. It is therefore conceivable that our primeval or natural mode of time keeping involves the perception, estimation, and coordination of events. I find it likely that events continues to subserve our sense of time and time-keeping efforts, especially for children who have not yet mastered the use of clock time. Instead of seeing events as a distraction to our perception of time, I suggest that our experience and understanding of time emerges from our perception of events.

    Does Gender Equality Cause Gender Differences in Values?: Reassessing the Gender-Equality-Personality Paradox2019Ingår i: Sex Roles, ISSN 0360-0025, E-ISSN 1573-2762Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The Gender-Equality-Personality Paradox (GEPP) is the finding that gender differences in personality are at their largest in the most gender equal countries. Previous known studies have not examined this relationship over time. Examining this linkage is crucial to our understanding of gender differences and personality development. In the present study, we contrast evolutionary perspectives predicting a gender divergence in personality due to progression in gender equality against biosocial perspectives predicting convergence. Using data from all eight rounds of the European Social Survey (n = 235,339) across 32 European countries, we report three findings. First, in accordance with the evolutionary perspective, country-level gender equality is positively associated with gender differences in basic human values. Second, in accordance with the biosocial perspective, we find evidence supporting gender convergence in basic human values. Third, contradicting both evolutionary and biosocial assumptions, we find no evidence that gender equality causes gender differences in values. We argue that there is a need to explore alternative explanations to the observed cross-sectional association between gender equality and personality differences, as well as gender convergence in personality over time.

    Retrieval practice in relation to material difficulty and episodicmemory: an examination of the episodic context account2018Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Framplockning av information från långtidsminnet genom testning (s.k. retrieval practice eller testbaserat lärande) gör materialet lättare att minnas senare jämfört med upprepad inläsning. Denna testeffekt är robust och har starkt stöd i empirisk forskning men vilka mekanismer som ligger bakom är inte lika klarlagt. Denna uppsats ämnade att undersöka effekterna av testbaserat lärande i relation till materialets svårighetsgrad samt individuella variationer i episodiskt minne över tid. Utgångspunkten var “the episodic context account”, en teoretisk förklaring för testeffekten i vilket episodiskt minne spelar en central roll. Fyrtiotre universitetsstudenter delades in i två experimentella betingelser (läsning-testning och upprepad läsning). Individuell prestation på ett datorbaserat test som gick ut på att memorera lätta och svåra ordpar vid tre tidfällen (direkt, en vecka senare och två veckor senare) samt episodiskt minne mättes. Resultaten visade på en signifikant testeffekt över tid och testeffekten i relation till materialets svårighetsgrad och individuella variationer i episodisk minnesförmåga analyserades och diskuteras. Resultaten gav stöd för testeffekten och ”the episodic context account” och att testbaserat lärande är en användbar inlärningsstrategi.

    The Effects Of Interactive Metronome Training On Female Soccer Players Timing Ability2012Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The aim of this study was to investigate how timing training by Interactive Metronome ® (IM) affects motor timing and rhythmicity in soccer players. Twenty-four female soccer players (age 19 ± 2.8) participated, and were randomly assigned to either a control or an IM training group. All participants took part in a functional magnetic resonance imaging (fMRI) session before the start of the training period, to find out what brain areas are activated during different tempos. The fMRI outcomes indicate that some of the active areas are the inferior parietal cortex (BA 40), frontal/SMA and precentral cortex and postcentral (BA 6) and inferior frontal cortex (BA 45). Pre- and post-measurements of motor timing deviation and variability was made. The result shows that after four week of IM training a significant improvement of motor timing was found for the IM group in comparison to the control group. The findings indicate that timing training can improve timing ability in healthy sport perpetrators.
