    Skogen i våra hjärtan: Erfarenheter, emotionella band, värderingar och attityder till skog, natur och allemansrätten2015Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Swedish landscape is dominated by highly valued forests and stakeholders argue different uses. The aim of this study was to investigate peoples experience, emotional bonds and values of forests and nature, their attitudes towards human utilization of nature and right of public access (allemansrätt), including relationships them in between. All in all 663 university students among who 254 were women and 401 were men, with the mean age of 24, answered a survey. The results from correlations show relationships between all variables. An attitude saying that the right of public access is important was predicted by stronger emotional bonds and spending more time in the forest. An attitude saying that the right of public access should be restricted was predicted by higher valuing of forest production and was more common among forest owners. The results implicate that emotions, which are strong incentives for action and created by experience, should be considered to better accomplish environmental goals. Environments necessary for experiencing nature should be provided, which is today made possible by right of public access to nature.

    Social media as the Cosmo Neighborhood2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    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 Tool2011In: Traffic Injury Prevention, ISSN 1538-9588, E-ISSN 1538-957X, Vol. 12, no 6, p. 621-629Article in journal (Refereed)
    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)2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    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 judgments2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Decision-making is an important part of everyday life and we often need to make trade-offs among different alternatives with desirable traits. Previous studies investigating the anchoring bias suggest that when a question is asked with a reference value, the reference value will affect the answer to that question. This effect seems to occur in a variety of different domains. However, previous studies have mainly focused on anchoring using inference questions. The present study, therefore, aims to investigate if high and low anchors have an effect, not only on inference judgments but also on subjective preferences when making a trade-off decision. A computer-based questionnaire was used to collect data (N = 90) in a between-subject design. The anchor showed to have an effect on the inference questions. For the preference questions, one of the questions were close to the chosen threshold (p < .05). The other question for preference showed not to be significant. The result from this study imply that the anchoring effect was more explicit in inference judgment than in preferences with trade-offs.

    Effects of Task Demands on Olfactory, Auditory, and Visual Event-Related Potentials Suggest Similar Top-Down Modulation Across Senses2018In: Chemical Senses, ISSN 0379-864X, E-ISSN 1464-3553, Vol. 43, no 2, p. 129-134Article in journal (Refereed)
    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 approach2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Previous research has studied the relationship between bilingualism and cognitive abilities. In some of those studies results have shown that bilinguals perform better than monolinguals in visual Simon tasks (i.e. they are less distracted by the incongruent stimuli). The aim of the current study is to see if a similar effect can be found in Simon tasks using the tactile and auditory sensory modalities. In this study bilingual participants (36 university students) with different proficiency in their second language performed a Simon task employing two intensities of vibration and two different sounds as the relevant stimuli. The results indicated no negative correlation between either bilingual proficiency and Simon effect or daily use of the second language and Simon effect when controlling for working memory. Without controlling for working memory a negative correlation for the tactile condition and a positive correlation for the auditory condition between Simon effect and daily use of the second language was found. It’s concluded that the statistical power of this study suffers from a lack of participants and that if the test was reproduced with more participants with a greater spread in their language abilities a stronger effect might be seen. Also concluded is that more cross-modal studies need to be performed before conclusions about general cognitive effects of bilingualism can be drawn.

    Ledarskapets effekt på prestation och upplevd motivation - en experimentell studie2016Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Within sports, leadership is considered having a great impact on individuals’ motivation. Leadership could, within a Self-Determination Theory (SDT) framework, be sorted into two different styles, autonomous and controlling leadership. There is a gap in current research concerning the effects of autonomous and controlling leadership on motivation in experimental settings. The aim of the present study was to, in an isolated environment, examine how an autonomy supportive- or a controlling leadership affects intrinsic motivation and performance. The study included 37 participants who, over a period of 20 minutes, performed a lego building task under a neutral, an autonomy supportive- or a controlling leadership style condition. The results indicated that the controlling leadership style had a negative impact on motivation and that the controlled group had lower perceived competence compared to the autonomous group. None of the leadership styles affected performance. Further, perceived motivation was found to significantly correlate with task.

    Test-enhanced learning and the effects of individual differences in cognition and personality2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    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 Characteristics2017In: Journal of Cognitive Education and Psychology, ISSN 1945-8959, E-ISSN 1810-7621, Vol. 16, no 3, p. 241-259Article in journal (Refereed)
    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 task2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    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?2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Evolutionary psychology explains and predicts human behaviour based on its adaptive value. Some apparently non-adaptive behaviours such as humans’ devotion to music can be explained by sexual selection of costly signals, since it takes time and effort to learn to play an instrument well. Here, participants rated pictures of persons of the opposite sex that were said to play a piece of music that was heard while watching each picture. The music performances were either of low, medium, or high level of skill, and a better performance was predicted to lead to higher ratings of partner attractiveness because it is more costly. No effect of the music was found, except that women rated men as less desirable for a long-term relationships when the skill level was high than when it was medium.

    The effects of sleep disturbances on memory2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The objective of this thesis was to examine the effects of sleep quality and non-restorative sleep on both subjective and objective memory function in an elderly population. Data was drawn from a longitudinal study in Umeå and consisted initially of 956 persons. After excluding people under 65 years of age and controlling for missing values the remaining sample consisted of 389 male (n=185) and female (n=204) persons. Linear multiple regressions were performed to analyze if sleep quality disturbance and non-restorative sleep predicted subjective and objective memory function. The result showed that both high values of sleep quality disturbances and non-restorative sleep were predictive of subjective memory complaints. However, neither of the two sleep dimensions were predictive of objective memory function. Future research should focus on the longitudinal effects of sleep disturbances on objective memory performance as well as the effect of sleep disturbances on episodic memory.

    Swedish student perceptions of achievement practices: the role of intelligence2018In: Intelligence, ISSN 0160-2896, E-ISSN 1873-7935, Vol. 69, p. 94-103Article in journal (Refereed)
    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.

    Psychometric studies of the Swedish version of the Adolescent Drug Abuse Diagnosis (ADAD) instrument2011Doctoral thesis, comprehensive summary (Other academic)
    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)2012In: Open Psychology Journal, ISSN 1874-3501, Vol. 5, p. 20-30Article in journal (Other academic)
    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?2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Previous research on human judgment and decision making has demonstrated systematic and predictable biases of judgment in experimental settings. One example of this is the tendency to intuitively violate the conjunction rule - a simple rule of probability. This was well illustrated in the famous Linda-problem. (Tversky & Kahneman, 1983). According to the dual-process theory of reasoning, (Kahneman, 2011) reasoning fallacies such as the conjunction fallacy occurs when people fail to use analytic reasoning and instead overly rely on their intuition. The dual process theory proposes that cognitive processes underlying our intuitive impulses and our conscious reasoning constitutes two different modes in the mind –system 1 and system 2- and that the intuitive system 1 are not able to compute probabilities. Furthermore, it is assumed that processes that are labeled system 1 are fast whereas system 2 are thought to be slow. We tested these time course assumptions of dual process theory in a within-subject design by comparing response time latencies between conjunction fallacy judgments and accurate probability judgments. The results showed that inducing accurate responding did not result in delayed response latency. This indicates that making accurate probability judgments does not require more processing time which goes against what would be expected by the dual-process framework.

    Hypertension, Infection and Inflammation and their Effects on Memory and Visuospatial Skills in Ageing2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Blood pressure has previously been associated with decline in memory over time, though the exact mechanism behind this effect is uncertain. Infections, which can lead to systemic inflammation have also been linked to some cardiovascular damage to the brain, known as microbleeds, which have themselves been linked to greater declines in cognition in old age. The present study investigates whether blood pressure, a self-reported history of infection, and an indirect measure of inflammation known as the erythrocyte sedimentation rate have any association with on episodic and semantic memory and visuospatial skills in the Betula study, a Swedish longitudinal population study. The effect of elevated blood pressure (over 140 mm Hg systolic and/or 90 mm Hg diastolic), high blood sedimentation (top 33% against bottom 33% of participants), and self-reported infection were all found to not have any significant effect on episodic memory, semantic memory or visuospatial skills. Some of the possible explanations are elaborated in the discussion.

    Train your brain: updating, transfer, and neural changes2009Doctoral thesis, comprehensive summary (Other academic)
    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 performance2010In: Personality and Individual Differences, ISSN 0191-8869, E-ISSN 1873-3549, Vol. 49, no 5, p. 457-460Article in journal (Refereed)
    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.

    Developmental progression and side specialization in upper-limb movements from 4 to 8 years in children born preterm and fullterm2018In: Developmental Neuropsychology, ISSN 8756-5641, E-ISSN 1532-6942, Vol. 43, no 3, p. 219-234Article in journal (Refereed)
    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.

    Personality and mental health: An investigation of South African police trainees2011In: Psychological Reports, ISSN 0033-2941, E-ISSN 1558-691X, ISSN 0033-2941, Vol. 108, no 1, p. 301-316Article in journal (Refereed)
    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 adolescence2018In: Personality and Individual Differences, ISSN 0191-8869, E-ISSN 1873-3549, Vol. 134, p. 66-70Article in journal (Refereed)
    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.

    Aspects of modern health worries as predictors of development of anxiety and depression symptoms2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Worries about the negative health effects of modern life (Modern health worries, MHW) have increased during the last decades, but the phenomenon is not fully understood. The present study investigated the associative and predictive relationship between different types of MHW and symptoms of anxiety and depression in a large sample from Västerbotten county, Sweden (n=2223). The four subscales of the Modern Health Worries Scale (MHWS) were used to assess different types of MHW, while symptoms of depression and anxiety were assessed by using the Hospital Anxiety and Depression Scale. Spearman's correlation analysis and hierarchical multiple regression analysis were used to assess the degrees of association and prediction, respectively. It was shown that the subscales were associated with symptoms of both anxiety and depression to varying degrees, however MHW did not significantly predict symptoms of neither anxiety nor depression. This suggests that when using the MHWS in clinical settings, examining the subscales rather than the global score of MHWS provides a more nuanced understanding of an individual's experience. It also suggests that experiencing MHW does not cause an increase in neither anxiety nor depression.

    Evaluating the effect of the Sensavis visual learning tool on student performance in a Swedish elementary school2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Dual coding theory implies that engaging multiple modalities (e.g., visual, auditory) in instruction enhances learning. Presenting information via 3D images and 3D animations appears to improve student performance but the results are inconsistent across multiple studies. The present study investigated the effect of the Sensavis visual learning tool, a 3D educational software, on performance in chemistry among students in a Swedish elementary school. Thirty-seven students from grades 7 and 9 received training involving a 3D animation on chemical bonds while nineteen students in grade 8 had traditional instruction. ANCOVA results controlling for age and average chemistry grade revealed a statistically significant difference in the posttest performance with the control group outperforming both experimental groups. These results indicate that the Sensavis tool did not have a positive effect on learning chemistry compared to traditional instruction. Interpretation of the results is presented in discussion.

    Utvärdering av KONTAKT i en klinisk verksamhet: Förändringar i sociala färdigheter hos en grupp 15-åriga pojkar med autismspektrumtillstånd2015Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    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.

    Components and Drivers of Long-term Risk Communication: Exploring the Within- Communicator, Relational, and Content Dimensions in the Swedish Forest Context2017In: Organization & environment, ISSN 1086-0266, E-ISSN 1552-7417, Vol. 30, no 2, p. 162-179Article in journal (Refereed)
    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 Acceptability2018In: Environment and Behavior, ISSN 0013-9165, E-ISSN 1552-390X, Vol. 50, no 2, p. 159-186Article in journal (Refereed)
    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-tasking2017In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 12, no 12, article id e0189299Article in journal (Refereed)
    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 Recall2018In: Frontiers in Psychology, ISSN 1664-1078, E-ISSN 1664-1078, Vol. 9, article id 1872Article in journal (Refereed)
    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.

    PÅVERKAN AV ORGANISATIONSFÖRÄNDRING, ROLLTYDLIGHET OCH LEDARSTÖD PÅ ÖVERENGAGEMANG2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    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 curiosity2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    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-keeping2015In: Frontiers in Psychology, ISSN 1664-1078, E-ISSN 1664-1078, Vol. 6, article id 259Article in journal (Refereed)
    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.

    Retrieval practice in relation to material difficulty and episodicmemory: an examination of the episodic context account2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Intentional retrieval of information from memory (also known as retrieval practice or test-enhanced learning) produces better long-term retention compared to restudy, a phenomenon known as the testing effect. While this effect is robust and has gained strong support in empirical research, the mechanisms are less well understood. The purpose of this thesis was to evaluate the effects of retrieval practice in relation to material difficulty and individual variations in episodic memory across time. The episodic context account, a theoretical explanation for the testing effect in which episodic memory plays a central role, was point of departure. Forty-three university students were divided into two experimental conditions (study-test and study). The to-be-learned material was 60 word-pairs (30 easy and 30 difficult). Learning was assessed by means of a cued recall test at three occasions (immediately, one week later, and two weeks later) and a measure of episodic memory was collected. Results revealed a significant testing effect across time and its relations to material difficulty and individual variations in episodic memory are analyzed and discussed. The results supported the testing effect paradigm and the episodic context account and indicated that retrieval practice is a useful and effective learning strategy.

    The Effects Of Interactive Metronome Training On Female Soccer Players Timing Ability2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    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.

    Interaktionen mellan nyfikenhet och yttre motivation2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Curiosity is an intrinsic aspiration to obtain new information. It has been considered that external motivation inhibits curiosity, but over the last years new research has indicated a partially different relationship. To investigate the interaction between curiosity and external motivation a picture-based learning experiment was constructed, in which the participants were rewarded, alternatively punished for obtaining new information which pleased their curiosity. In the first part of the experiment, the participants scored their curiosity of mosaic-covered pictures. In the second part of the of the experiment, the scored mosaic-covered pictures were consequently presented next to a constant picture. The task for the 24 participants was then to choose one of the pictures in each round. The chosen mosaic-covered picture would then show according to a certain waiting time - either short or long - depending on if it was new or recurring. Whether the new or recurring picture had a short or long average waiting time varied between the two in-group conditions. It was hypothesized that the participants would be externally motivated to minimize the waiting time by learning and favouring the category of pictures with the shortest waiting time. In addition, it was hypothesized that the participants would be curious of the mosaic-covered pictures. In one of the conditions, the participants external motivation coincided with their curiosity, in the other condition the external motivation was in conflict with their curiosity. In a third controlling condition, the dimension of curiosity was eliminated to measure the learning of the waiting time. The experiment showed that more rounds are needed to learn the waiting time in the controlling conditions compared to when the new pictures also had a shorter average waiting time. When new pictures were associated with a longer average waiting time, it divided the participants into two groups. In one group the participant rarely chose new pictures (proportion: 0.75 – 1.0) while the participants in the other group to a large extent chose new pictures (proportion: 0.0077 – 0.069). These differences were also shown in the participants personal traits connected to curiosity. All together, the study supports the idea that curiosity and external motivation can be integrated and that personal traits are related to the evaluation of information.

    Coping with Anxiety Sensitivity during Adolescence2017Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The relation between Anxiety Sensitivity (AS) and certain anxiety disorders such as Panic Disorder and the panic response itself are well established by theory and research. Adolescence is understood to be a risk period for the development of Anxiety disorders. Certain styles of coping such as avoidance has beensuggested to be risk factors as well. In this study, the relation between AS and coping is explored using self-report measures (CASI-R and A-COPE), aiming to see if adolescents with high or low AS have an association with certain coping styles, understood by theory also to be potential risk factors. No reliable association were found between groups with high or low AS and any coping style. AS and total extent of coping did not correlate. A small and negative, significant correlation was found between age and AS.

    Byggnadsrelaterad ohälsa : Kompetensutveckling inom hälsovården2014Report (Refereed)
    Abstract [en]

    There is a growing demand for education on indoor environment and building-related illness, both in the context of basic vocational education and training courses for professionals. Health problems, caused by poor indoor air quality in the workplace, are investigated by the occupational health service. However, those working with occupational health today, do not always have sufficient knowledge about the indoor environment and building-related illness and often lack the capacity to participate as experts in investigations of the indoor environment in a workplace. To improve health care, staff should be trained on e.g. risk factors for poor indoor air quality, common health problems and impact on working capacity and productivity, the impact of psychosocial factors as well as liability issues and health economic implications. Open Educational Resources (OER) and Massive Open Online Courses (MOOCs) can advantageously be used in the training of health professionals. Online education makes it easier for them to choose when to participate and the objectives of the education. Furthermore, OER also constitutes a means to develop knowledge transfer between Sweden and Finland.

    Är stillasittande och stress associerade med muskuloskeletala besvär hos kontorsarbetare?: -En tvärsnittsstudie2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Musculoskeletal disorders (MSD) constitute a major health problem. The symptoms consist of pain in muscles, joints, ligaments and surrounding tissues. Two causes of MSD in office work are stress and sedentary behaviour. The purpose of this study was to test the hypotheses that stress and sedentary behaviour are associated individually with MSD and associates more with MSD together than separately. The number of participants was 100 office workers, 48 women and 52 men, with sit and stand tables. The average age of all participants was 42 years. They responded to a five-piece web questionnaire to measure the variables stress and sedentary behaviour in relation to MSD. The standardized instruments PSS-10 (Perceived Stress Scale - 10) and NMQ (Nordic Musculoskeletal Questionnaire) were used, among other things, in the survey. Data was analyzed with multiple linear regression, two separate simple linear regressions and stepwise regression. The results showed statistical significance for stress and sedentary behavior together, only stress was associated with MSD (p = 0.011). The result of the two simple linear regressions resulted in stress associated with MSD (p = 0.008) while sedentary behavior did not (p = 0.280). the null hypotheses could not be rejected because sedentary behaviour did not associate with MSD and a comparison between adjusted R2 gave stress separately (adjusted R2 = 0.061) a better model than stress and sedentary behavior together (adjusted R2 = 0.056).

    Cross-Cultural Invariance of the Mental Toughness Inventory Among Australian, Chinese, and Malaysian Athletes: A Bayesian Estimation Approach2016In: Journal of Sport & Exercise Psychology (JSEP), ISSN 0895-2779, E-ISSN 1543-2904, Vol. 38, no 2, p. 187-202Article in journal (Refereed)
    Abstract [en]

    The aims of this study were to assess the cross-cultural invariance of athletes' self-reports of mental toughness and to introduce and illustrate the application of approximate measurement invariance using Bayesian estimation for sport and exercise psychology scholars. Athletes from Australia (n = 353, M-age = 19.13, SD = 3.27, men = 161), China (n = 254, M-age = 17.82, SD = 2.28, men = 138), and Malaysia (n = 341, M-age = 19.13, SD = 3.27, men = 200) provided a cross-sectional snapshot of their mental toughness. The cross-cultural invariance of the mental toughness inventory in terms of (a) the factor structure (configural invariance), (b) factor loadings (metric invariance), and (c) item intercepts (scalar invariance) was tested using an approximate measurement framework with Bayesian estimation. Results indicated that approximate metric and scalar invariance was established. From a methodological standpoint, this study demonstrated the usefulness and flexibility of Bayesian estimation for single-sample and multigroup analyses of measurement instruments. Substantively, the current findings suggest that the measurement of mental toughness requires cultural adjustments to better capture the contextually salient (emic) aspects of this concept.

    The effect of task relevancy in non-consciously retained information in working memory2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The relationship between cognitive processes and consciousness has been of interest for a long time in the science community. Recent studies showed that it’s possible to non-consciously retain information in working memory.  This study aimed to replicate previous findings, and to investigate the effect of task relevancy to the retention of non-conscious information. This study used a delayed-match-to-sample task with a cue manipulating the attention, and continuous flash suppression to render the perceptual experience non-conscious on 16 participants.  Analyses showed that cue validity affected the accuracy performance and response time for items reported not seen. Implications of study design, results and theories are deliberated in the discussion.

    Emotional Well-Being Related to Time Pressure, Impediment to Goal Progress, and Stress-Related Symptoms2016In: Journal of Happiness Studies, ISSN 1389-4978, E-ISSN 1573-7780, Vol. 17, no 5, p. 1789-1799Article in journal (Refereed)
    Abstract [en]

    We propose that emotional well-being in everyday life is partially related to the balance of positive and negative affect associated with everyday routine activities. Factors that interfere with positive affect associated with such activities would therefore have negative impacts on emotional well-being. Supporting that time pressure is one such factor, we find in Study 1 for a representative sample of Swedish employees (n = 1507) answering a survey questionnaire that emotional well-being has a negative relationship to time pressure. In Study 2 we test the hypothesis that the negative effect of time pressure on emotional well-being is jointly mediated by impediment to goal progress and time stress. In another survey questionnaire a sample of Swedish employees (n = 240) answered retrospective questions about emotional well-being at work and off work, experienced impediment to goal progress, experienced time pressure, and stress-related symptoms. Statistical mediation analyses supported the proposed hypothesis.

    Short telomere length is associated with impaired cognitive performance in European ancestry cohorts2017In: Translational Psychiatry, ISSN 2158-3188, E-ISSN 2158-3188, Vol. 7, article id e1100Article in journal (Refereed)
    Abstract [en]

    The association between telomere length (TL) dynamics on cognitive performance over the life-course is not well understood. This study meta-analyses observational and causal associations between TL and six cognitive traits, with stratifications on APOE genotype, in a Mendelian Randomization (MR) framework. Twelve European cohorts (N = 17 052; mean age = 59.2 +/- 8.8 years) provided results for associations between qPCR-measuredTL (T/S-ratio scale) and general cognitive function, mini-mental state exam (MMSE), processing speed by digit symbol substitution test (DSST), visuospatial functioning, memory and executive functioning (STROOP). In addition, a genetic risk score (GRS) for TL including seven known genetic variants for TL was calculated, and used in associations with cognitive traits as outcomes in all cohorts. Observational analyses showed that longer telomeres were associated with better scores on DSST (beta = 0.051 per s. d.-increase of TL; 95% confidence interval (CI): 0.024, 0.077; P = 0.0002), and MMSE (beta = 0.025; 95% CI: 0.002, 0.047; P = 0.03), and faster STROOP (beta = -0.053; 95% CI: -0.087, -0.018; P = 0.003). Effects for DSST were stronger in APOE epsilon 4 non-carriers (beta = 0.081; 95% CI: 0.045, 0.117; P = 1.0 x 10(-5)), whereas carriers performed better in STROOP (beta = -0.074; 95% CI: -0.140, -0.009; P = 0.03). Causal associations were found for STROOP only (beta = -0.598 per s. d.-increase of TL; 95% CI: -1.125, -0.072; P = 0.026), with a larger effect in epsilon 4-carriers (beta = -0.699; 95% CI: -1.330, -0.069; P = 0.03). Two-sample replication analyses using CHARGE summary statistics showed causal effects between TL and general cognitive function and DSST, but not with STROOP. In conclusion, we suggest causal effects from longer TL on better cognitive performance, where APOE epsilon 4-carriers might be at differential risk.
