    Predicting attention shifting abilities from self-reported media multitasking2019Inngår i: Psychonomic Bulletin & Review, ISSN 1069-9384, E-ISSN 1531-5320, Vol. 26, nr 4, s. 1257-1265Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Media multitasking is an increasingly prominent behavior in affluent societies. However, it still needs to be established if simultaneous use of several modes of media content has an influence on higher cognitive functions, such as divided attention. In this study, attention shifting was the primary focus, since switching between tasks is assumed to be necessary for media multitasking. Two tasks, the number–letter and local–global task, were used as measures of switching ability. The cognitive reflections task was included to control for possible effects of intelligence. Results from linear regression analyses showed that higher levels of media multitasking was related to lower switching costs in the two attention-shifting tasks. These findings replicate previous findings suggesting that heavy media multitaskers perform better on select measures of task switching. We suggest two possible explanations for our results: media multitasking may practice skills needed for switching between tasks, or high media multitaskers are choosing this style of technology use due to a dominating personality trait in this group.

    Effects of perceived long-term stress on health and memory functioning2010Inngår i: Abstracts of the Psychonomic Society, 2010, s. 78-78Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The study examined effects of perceived long-term stress on health and memory functioning in middle-aged individuals (40–60 years). Participants in the Betula study (Nilsson et al., 1997) describing themselves as being stressed in general over three measurement occasions (10 years in total) were compared with a matched (sex and education) group (n = 98) reporting no stress. The results revealed a higher incidence of depressive symptoms, flus, and not-healthy-ratings over time for the stress group. In addition, the stress group provided more negative subjective memory ratings, whereas time-related change in memory performance, indicative of a high degree of cognitive stability, did not differ from that of controls. Degree of perceived stress is discussed as a factor underlying variations in regard to the outcome of studies of perceived stress.

    The influence of social relationships and leisure activity on adult cognitive functioning and risk of dementia: Longitudinal population-based studies2015Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Today, as we live longer, dementia diseases are becoming more prevalent around the world. Thus, further knowledge of how to maintain levels of cognitive functioning in old age and how to identify factors that postpone the onset of dementia are of acute interest. Lifestyle patterns and social life are important aspects to consider in this regard.

    This thesis includes three studies. Study I investigated the association between participation in various leisure activities in old age (≥65 years) and risk of incident all-cause dementia. Analyses of the total follow-up time period (15 years) showed that higher levels of “Social” and “Total” leisure activity were associated with decreased risk of dementia. In Study II, the aim was to investigate the association between various aspects of social relationships in old age (≥65 years) and risk of incidents of all-cause dementia and Alzheimer's disease. Results showed that over the total follow-up period (16 years) higher values on the relationship index were associated with reduced risk of both dementia and Alzheimer's disease. Visiting/visits of friends and acquaintances more than once a week was related to decreased risk for all-cause dementia, but not for Alzheimer's disease. However, in neither Study I nor II did any of these factors alter the risk of all-cause dementia or Alzheimer's disease when near-onset dementias were removed from the analyses (Study I, up to five years; Study II, up to three years).

    In Study III the aim was to investigate the association between social network size and cognitive ability in a middle-aged (40–60 years) sample. The idea was that if social network size can moderate negative age-related influence on memory functions, it might also put an individual on a cognitive trajectory that is beneficial in old age. Results from longitudinal analyses showed that baseline network size was positively related to five-year changes in semantic memory and with changes in both semantic and episodic memory at the ten-year follow-up. Social network size was unrelated to changes in visuospatial performance.

    Taken together, enrichment factors measured in old age (≥ 65 years) did not alter the risk of all-cause dementia or Alzheimer's disease when near-onset dementias were removed from the analyses. These results might reflect protective short-term effects or reverse causality, meaning that in the prodromal phase of dementia individuals tend to withdraw from activity. Social network size in middle age (40-60 years), however, appears to have beneficial long-term effects on cognitive functioning. The results highlight the importance of long follow-up periods and the need to adjust for the influences of reverse causality when investigating the impact of a socially and mentally active life on cognitive functioning.

    Different Features of Bilingualism in Relation to Executive Functioning2019Inngår i: Frontiers in Psychology, ISSN 1664-1078, E-ISSN 1664-1078, Vol. 10, nr 269Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The notion that the long-term practice of managing two languages is beneficial for the executive control system is an ongoing debate. Criticism have been raised that studies demonstrating a bilingual advantage often suffer from small sample sizes, and do not control for fluid intelligence as a possible confound. Taking those suggested factors into account, focusing on older bilingual age groups and investigating the potential effects of linguistic distances, this study aimed to improve the interpretations of the bilinguals’ advantages. Measures of inhibition (Flanker, Stroop, Simon task) and switching (Number-letter, Color-Shape, Local-global task) were collected in participants in the ages 50-75 years (n = 193). Despite a large study sample, results did not support any beneficial effects related to improve processing costs in executive functioning. Sub-analyses of the two different language groups (Swedish – Finnish / Swedish – English) intended to investigate the effect of linguistic distances did not change this outcome. Future studies exploring the potential long-term term effects of bilingualism would benefit from identifying tests of cognitive control with greater ecological validity and include other measures of cognitive functioning. Language learning interventions may also be a promising tool for future research.

    Complexity of Primary Lifetime Occupation and Cognitive Processing2019Inngår i: Frontiers in Psychology, ISSN 1664-1078, E-ISSN 1664-1078, Vol. 10, s. 1-12, artikkel-id 1861Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Today, there are a lack of studies focusing on the relationship between occupational complexity and executive functioning. This is noteworthy since executive functions are core aspects of cognitive processing. The present study was aimed to investigate if three occupational complexity factors (with data, people, and things) of main lifetime occupation were related to performance in executive tasks (inhibition, switching, updating). We analyzed cross-sectional data that were available for 225 participants aged 50–75 years. Results from structural equation models showed that higher complexity levels of working with data were related to lower error rates in the updating component of cognitive control. In addition, higher rates of complexity working with people was associated with lower error rates in task-switching, which also persisted after adjustment of fluid intelligence. Complexity with things, however, was not related to performance in the executive tasks. Future studies would benefit from a longitudinal design to investigate if the results from this study also hold in the long term and to further investigate the directionality between factors.

    Blood Pressure Levels and Longitudinal Changes in Relation to Social Network Factors2016Inngår i: Psychological Topics, ISSN 1332-0742, Vol. 25, nr 1, s. 59-73Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The aim of this study was to examine the relationship between social network variables and levels of and longitudinal changes in blood pressure in a middle-aged/older sample. The participants (50-75 years at baseline; n=1097) responded to questions concerning social relationships at baseline and their blood pressure (diastolic, systolic) was measured. Blood pressure levels were reassessed 5, 10, and 15 years later. Latent growth models with responses to questions concerning social relationships as predictors and basic demographic factors (age, sex) as covariates, unexpectedly indicated that a more limited social network (no close friend, few visits, little contact with friends in other ways, not living with someone, and a composite index based on all questions) was associated with significantly lower diastolic blood pressure levels. For systolic blood pressure a similar result was observed for one of the variables (lack of a close friend). In general, these effects diminished over time, as indexed by the positive relationship between several of the social variables and slope. The results were little affected by inclusion of additional covariates (e.g. measures of psychological distress, smoking/alcohol habits, and BMI) suggesting that the origins of this unexpected pattern of findings must probably be sought for in other subjectrelated factors, such as, for example, increased help seeking. Future studies should consider qualitative aspects (e.g. feelings of loneliness, quality of social relationships) in addition to structural aspects to provide a better understanding of these associations.

    Longitudinal effects of bilingualism on dual-tasking2017Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 12, nr 12, artikkel-id e0189299Artikkel i tidsskrift (Fagfellevurdert)
    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 Recall2018Inngår i: Frontiers in Psychology, ISSN 1664-1078, E-ISSN 1664-1078, Vol. 9, artikkel-id 1872Artikkel i tidsskrift (Fagfellevurdert)
    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.

    Ger en aktiv livsstil bättre minne?2011Inngår i: Svensk Idrottsforskning: Organ för Centrum för Idrottsforskning, ISSN 1103-4629, Vol. 20, nr 1, s. 43-45Artikkel i tidsskrift (Annet vitenskapelig)
    Abstract [sv]

    Det sägs ibland att aktivteter som stimulerar hjärnan förbättrar minnet. En rad studier indikerar också att olika typer av livsstilsfaktorer hänger samman med prestation i kognitiva test. De visar att dålig minnesförmåga är överrepresenterad hos dem som inte ägnar sig åt fritidsaktiviteter såsom att läsa, idrotta och lägga pussel.

    Social relationships and risk of dementia: a population-based study2015Inngår i: International psychogeriatrics, ISSN 1041-6102, E-ISSN 1741-203X, Vol. 27, nr 8, s. 1391-1399Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: The objective was to examine whether aspects of social relationships in old age are associated with all-cause dementia and Alzheimer's disease (AD).

    Methods: We studied 1,715 older adults (≥ 65 years) who were dementia-free at baseline over a period of up to 16 years. Data on living status, contact/visit frequency, satisfaction with contact frequency, and having/not having a close friend were analyzed using Cox proportional hazards regressions with all-cause dementia or AD as the dependent variable. To control for reverse causality and to identify potential long-term effects, we additionally performed analyses with delayed entry.

    Results: We identified 373 incident cases of dementia (207 with AD) during follow-up. The variable visiting/visits from friends was associated with reduced risk of all-cause dementia. Further, a higher value on the relationships index (sum of all variables) was associated with reduced risk of all-cause dementia and AD. However, in analyses with delayed entry, restricted to participants with a survival time of three years or more, none of the social relationship variables was associated with all-cause dementia or AD.

    Conclusions: The results indicate that certain aspects of social relationships are associated with incident dementia or AD, but also that these associations may reflect reverse causality. Future studies aimed at identifying other factors of a person's social life that may have the potential to postpone dementia should consider the effects of reverse causality.

    Leisure-time activity in old age as predictors of impending dementia: A 15-year prospective study.2012Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This study examined the relationship between leisure activities and risk of dementia in a sample of healthy older individuals, dementia free at the beginning of the project. Data were drawn from a population-based longitudinal study (the Betula project) and the participants were followed up for 15 years. At baseline, participants were asked about their frequency of participation in 15 selected leisure activities. When age, gender, education, APOE and other potential confounders were controlled for, results revealed quite moderate effects on dementia after analysis of the activities separately. However, by weighting each activity into a mental, social and physical dimension (based on valuation by the participants), and then summarizing into a score for each dimension, we further investigated if level of engagement could predict impending dementia. Preliminary results indicate that the dimensions may have influence on the risk of dementia for certain age groups. The study also showed that the strongest predictor of dementia is being a carrier of the APOE ɛ4 allele. The outcomes are discussed in terms of important methodological difference between studies concerning the effects of leisure activities in preventing dementia diseases.

    Leisure Activity in Old Age and Risk of Dementia: a 15-Year Prospective Study2014Inngår i: The journals of gerontology. Series B, Psychological sciences and social sciences, ISSN 1079-5014, E-ISSN 1758-5368, Vol. 69, nr 4, s. 493-501Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objectives. The aim of this study was to investigate whether leisure activity is associated with incident dementia in an older sample.

    Method. We examined a sample of 1,475 elderly (>= 65 years) who were dementia free at baseline over a follow-up period of up to 15 years. In addition to analyses involving the total time period, separate analyses of three time periods were performed, 1-5, 6-10, and 11-15 years, following baseline measurement of leisure activity.

    Results. After controlling for a variety of potential confounders, analyses of data for the total time period revealed that higher levels of "Total activity" and "Social activity," but not "Mental activity," were associated with decreased risk of dementia. However, analyses of the separate time periods showed that this association was only significant in the first time period, 1-5 years after baseline.

    Discussion. The results from this study provide little support for the hypothesis that frequent engagement in leisure activities among elderly serve to protect against dementia diseases across a longer time frame. The finding of a relationship for the first time period, 1-5 years after baseline, could indicate short-term protective effects but could also reflect reverse causality.

    Distraction and facilitation: The impact of emotional sounds in an emoji oddball task2019Inngår i: PsyCh Journal, ISSN 2046-0252, E-ISSN 2046-0260, Vol. 8, nr 2, s. 180-186Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Emotional stimuli are argued to capture attention and consume attentional resources differently depending on their emotionalcontent. The present study investigates the impact of the automatic detection of unexpected and to-be-ignored emotional stimuli onhuman behavioral responses, and aims to unravel the differences in distraction between two negative emotional stimuli: sadness and anger.Forty participants (Mage= 25.5 years) performed a visual categorization task where angry and sad emoji faces were presented after eithera standard neutral tone (in 80% of trials) or a deviant emotional sound (tone changing in pitch; sad or angry sound in 10% of trials each)that was to be ignored. Deviant trials were either congruent (e.g., sad sound—sad face) or incongruent (e.g., angry sound—sad face).Although the stimuli presented to the participants were brief and to-be-ignored, results indicate that participants were significantly moredistracted by sad compared to angry stimuli (seen as prolonged response times). Findings are discussed with reference to the nature ofthe two negative emotions.

    The bilingual effects of linguistic distances on episodic memory and verbal fluency2020Inngår i: Scandinavian Journal of Psychology, ISSN 0036-5564, E-ISSN 1467-9450, Vol. 61, nr 2, s. 195-203Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The impact of linguistic distance or the relatedness between two languages, on bilinguals' episodic memory performance and verbal fluency is an understudied area. Thus, the purpose of this study was to determine if differences in linguistic distances have differential effects on these abilities. Measures of episodic recognition, categorical fluency, and global cognitive functioning were also considered in the analyses. Two matched samples with participants living and educated in Sweden were drawn from the Betula Prospective Cohort Study. Results showed that bilinguals who speak linguistically similar languages (Swedish and English), performed significantly better than monolinguals on both episodic memory recall and letter fluency, while bilinguals who speak two languages that are more distant (Swedish and Finnish), showed no advantages compared to their monolingual counterparts. For both tasks, however, a linear trend was observed indicative of better performance for the Swedish-English group compared to the Finnish-Swedish group, and for the Swedish-Finnish group compared to the monolinguals group. As expected, no differences between groups were found in any of the other cognitive tasks. Overall, results suggest that the impact of linguistic distances should be explored in more detail in the future.

    The Impact of Emotional Deviant Sounds on Emoji Faces in a Sustained Attention Task2016Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The involuntary shift of attention to emotional sounds were investigated in a cross-modal oddball task in which participants categorized angry and disappointed emoji faces. Prior to each face, a standard tone was presented (80% of trials) or a deviant “disappointed” or a buzzing “angry” sound (20% of trials). The deviant trials were either congruent (e.g., disappointed sound/disappointed emoji) or incongruent trials (e.g., a disappointed sound/angry emoji). Results showed that the emotional content of the deviant sounds interacted with the processing of the faces, but that the effect was only present in the congruent trials. Participants showed deviance distraction (prolonged response times compared to standard) in the disappointed trials and facilitation (no deviance distraction) in the angry deviant trials. The facilitation (or lack of distraction) caused by the angry deviant sound in the congruent trial may have been a result of an arousal effect due to the processing of threat.

    Executive Processes Underpin the Bilingual Advantage on Phonemic Fluency: Evidence from Analyses of Switching and Clustering2019Inngår i: Frontiers in Psychology, ISSN 1664-1078, E-ISSN 1664-1078, Vol. 10, artikkel-id 1355Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Bilinguals often show a disadvantage in lexical access on verbal fluency tasks wherein the criteria require the production of words from semantic categories. However, the pattern is more heterogeneous for letter (phonemic) fluency wherein the task is to produce words beginning with a given letter. Here, bilinguals often outperform monolinguals. One explanation for this is that phonemic fluency, as compared with semantic fluency, is more greatly underpinned by executive processes and that bilinguals exhibit better performance on phonemic fluency due to better executive functions. In this study, we re-analyzed phonemic fluency data from the Betula study, scoring outputs according to two measures that purportedly reflect executive processes: clustering and switching. Consistent with the notion that bilinguals have superior executive processes and that these can be used to offset a bilingual disadvantage in verbal fluency, bilinguals (35-65 years at baseline) demonstrated greater switching and clustering throughout the 15-year study period.

    The impact of spoken action words on performance in a cross-modal oddball task2018Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 13, nr 11, artikkel-id e0207852Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this study a cross-modal oddball task was employed to study the effect that words spoken either non-urgently or urgently would have on a digit categorization task and if women would exhibit greater behavioral inhibitory control. The words were unrelated to the task itself, but related to the action required to complete the task. Forty participants (21 women) conducted a computerized categorization task while exposed to a sinewave tone as a standard stimulus (75% of the trials) or a to-be ignored word (press, stop) spoken either non-urgently or urgently as unexpected auditory deviant stimulus (6.25% trials for each category). Urgent words had sharp intonation and an average fundamental frequency (F0) ranging from 191.9 (stop) to 204.6 (press) Hz. Non-urgent words had low intonation with average F0 ranging from 103.9.9 (stop) to 120.3 (press) Hz. As expected, deviant distraction and longer response times were found by exposure to the word stop, but deviant distraction was not found to be significant with the word press or due to intonation. While the results showed that women had in general longer reaction times, there were no gender differences found related to the deviant distraction caused by word or intonation. The present results do not support the hypothesis that women have greater behavioral inhibitory control, but there was evidence that the meaning of the word could influence response times.

    Is Cognitive Functioning Important for Quality in Ageing?2014Inngår i: Abstracts of the Psychonomic Society, 2014, s. 87-87Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Well-being and happiness are two important aspects of quality in ageing. By using a large scale memory data base (the Betula study) the importance of cognitive status (episodic memory) for an individual’s subjective notion of well-being and happiness were investigated, both among middle- and old aged individuals. When a number of factors where controlled for (e.g., physical health, psycho-social aspects), results indicated no relationships between cognitive status and well-being or happiness, in any age group. However, data suggested that subjective experience of memory capacity seems to play an important role. Further, being married, having low levels of stress, and not having sleeping problems, also seem to be associated with both well-being and happiness. The result suggests that other factors, rather than cognitive status, plays a substantial roll in the quality of ageing. Future studies would benefit from using longitudinal data to be able to investigate these relationships over time.

    To what extent is subjective well-being in late adulthood related to subjective and objective memory functioning?: Five-year cross-lagged panel analyses2019Inngår i: Aging & Mental Health, ISSN 1360-7863, E-ISSN 1364-6915, Vol. 23, nr 1, s. 92-99Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Population aging motivated a focus in contemporary research on factors, e.g. cognitive functioning, that contribute to ‘aging well.’ However, something that has been overlooked is relation between memory functioning, determined by objective tests as well as subjective memory ratings, and subjective well-being (SWB).

    Objectives: The aim of the present study was to investigate cross-sectional and longitudinal (cross-lagged) relationships between episodic memory (both subjective and objective) and SWB.

    Method: A total of 586 older individuals (60–90 years) were assessed on multiple measures of the targeted constructs at baseline (Time 1) as part of the Betula cohort study. Five years later (Time 2), 354 of the participants returned for follow-up measurements and were included in cross-lagged panel analyses.

    Results: As expected, objective memory and subjective memory showed a pattern of cross-sectional age deficits and a mean level longitudinal decline was observed for objective memory. By contrast, SWB showed stable mean levels both across age and time. No cross-sectional or cross-lagged associations were observed between SWB and objective memory, whereas subjective memory and SWB showed a cross-sectional association.

    Conclusion: The results underscore that successful aging is a multifaceted construct with no or only weak associations between the investigated components. However, SWB and rate of change at the individual level should be considered to define successful aging.

    Are physical activity and sedentary behavior related to depression?2019Inngår i: COGENT PSYCHOLOGY, ISSN 2331-1908, Vol. 6, nr 1, artikkel-id 1633810Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Depression is an increasing public health concern with rising prevalence. Nevertheless, far from everyone seeks help or receives adequate treatment. Although psychotherapy and antidepressants still constitute the bulk of treatments offered, recent research suggests that physical activity (PA) can be a powerful adjunct therapy while sedentary behavior (SB) is a definite risk factor for developing depression. The aim of the present study was to investigate the relationship between PA, SB and depressive symptoms in a population (n = 962) of applicants for an online treatment study. This study hypothesised that there will be; (1) a positive relationship between SB and depressive symptoms, and (2) a negative relationship between PA and depressive symptoms. In addition we investigated whether the combination of a sedentary lifestyle and physical inactivity increased the risk for depressive symptoms. Finally, we also examined whether gender, age, marital status, educational level, or medication affected the relationship between PA, SB, and depressive symptoms. The results showed a positive correlation between SB and depression. There was, however, no statistically significant support for a negative relation between PA and depressive symptoms. Even though no conclusions about causality can be drawn, our results suggest that high SB, being a woman, being young, not being in a stable relationship, and current or previous medication are risk factors for depression. To be able to determine the causal direction, that is, whether high SB increases the risk for depressive symptoms, or if depressive symptoms increase the likelihood of high SB, further research is needed.

    Time on task matters most in video game expertise2018Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 13, nr 10, artikkel-id e0206555Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this study, we investigated whether working memory capacity (WMC), personality characteristics (grit) and number of matches played (time on task) can predict performance score (matchmaking rating [MMR]) in experienced players of a popular video game called Dota 2. A questionnaire and four online-based cognitive tasks were used to gather the data, and structural equation modelling (SEM) was used to investigate the interrelationships between constructs. The results showed that time on task was the strongest predictor of MMR, and grit also significantly influenced performance. However, WMC did not play a substantial role in predicting performance while playing Dota 2. These results are discussed in relation to sample characteristics and the role of deliberate practice and skill acquisition within the domain of playing Dota 2. Further, we suggest that future research investigates the social aspects of attaining skill, the relationship between personality and performance, and the qualitative aspects of time spent on a task.

    Effects of Perceived Long-Term Stress on Subjective and Objective Aspects of Memory and Cognitive Functioning in a Middle-Aged Population-Based Sample2013Inngår i: The Journal of Genetic Psychology, ISSN 0022-1325, E-ISSN 1940-0896, Vol. 174, nr 1, s. 25-41Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The longitudinal effects of perceived stress on measures of memory and two other cognitive functions (word fluency, visuospatial ability) in a middle-aged sample (4060 years, M age = 47.1 years, SD = 6.1 years; n = 192) were examined. A group describing themselves as stressed in general at baseline, and at follow-up measurement 5 and 10 years later (n = 96) was compared with a matched (age, sex) low-stress group (n = 96). The results revealed more depressive symptoms over time in the high-stress group. With regard to memory, a dissociation between subjective and objective measures was observed. Specifically, participants in the high-stress group rated their memory as worse over time as compared with controls, and reported a higher frequency of occurrence of everyday memory failures, effects partly independent of depressive symptoms. However, the groups did not differ in terms of objective episodic memory performance, word fluency or block design performance, with stable levels of performance over time regardless of perceived stress. The lack of effects of stress on cognitive performance is discussed in the light of factors such as stress level, age of the participants, and other individual difference factors.

    Mental demands at work and risk of dementia2020Inngår i: Journal of Alzheimer's Disease, ISSN 1387-2877, E-ISSN 1875-8908Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    High mental demands at work was examined as a possible protective factor to reduce the risk of dementia in 1,277 initially dementia-free participants, aged 60 years and older. The cohort was followed for a mean of 13.6 years. During follow-up, 376 participants developed all-cause dementia (Alzheimer’s disease = 199; vascular dementia = 145). The association between mental demands at work and dementia was analyzed with Cox hazard models, adjusted for a range of covariates. The results revealed no significant association between mental demands at work and incidence of dementia. Based on the measures used in this study, it was concluded that high mental demands at work may not reduce the risk of dementia later on in life.

    Social network size and cognitive functioning in middle-aged adults: cross-sectional and longitudinal associations2017Inngår i: Journal of Adult Development, ISSN 1068-0667, E-ISSN 1573-3440, Vol. 24, nr 2, s. 77-88Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The objective of the present study was to examine relations between social network size and three cognitive abilities (episodic memory, semantic memory, visuospatial ability) in middle-aged adults. We analyzed cross-sectional data on social network size and cognitive functioning that were available for 804 participants aged 40–60 years. In addition, we examined 5- and 10-year follow-up measurements of cognitive functioning that were available for 604 and 255 participants, respectively. Cross-sectional analyses revealed a positive association between social network size and each of the three cognitive abilities. Baseline network size was positively related to 5-year changes in semantic memory, and to 10-year changes in semantic as well as episodic memory, but was unrelated to changes in visuospatial performance. A minor portion of the sample (n = 131) had 10-year follow-up data on network size. Cross-lagged panel correlations revealed that baseline network size was associated with follow-up measurement in cognitive functioning (episodic memory, semantic memory), whereas baseline cognitive performance was unrelated to future network size. Together, the results demonstrate a small but positive relation between network size and declarative memory abilities, in line with models proposing a cognitive reserve built up by factors such as the increased cognitive stimulation associated with a more extensive social network.
