Background Postural control is dependent on the central nervous system’s accurate interpretation of sensory information to formulate and execute adequate motor actions. Research has shown that cognitive functions are associated with both postural control and fall risk, but specific associations are not established. The aim of this study was to expl...

This study explored the relationship between the big five personality traits and gaming disorder symptoms (GDS) in a sample of Dota 2 players. Recent research has indicated that the relationship between personality traits and GDS may depend on the video game genre investigated. However, the association between GDS and personality has yet to be inve...

The purpose of this study was to investigate whether symptoms of attention deficit hyperactivity disorder (ADHD) impact distraction by unexpected deviant sounds and vibrations. The hypothesis was a difference between individuals with low and high ADHD symptom severity in deviance distraction. In a cross-modal oddball task, we measured the impact of...

Introduction The inclusion of Internet Gaming Disorder (IGD) in the fifth revision of the Diagnostic and Statistical Manual of Mental Disorders ( DSM‐5 ) by the American Psychiatric Association and Gaming Disorder in the 11th revision of the International Classification of Diseases ( ICD‐11 ) by the World Health Organization requires consistent psy...

Objective: Treatments for adults with attention-deficit hyperactivity disorder (ADHD) are understudied, compared to children and adolescents with the same condition. In this systematic review and random-effects meta-analysis, we aim to evaluate the outcomes of computerized cognitive training (CCT) interventions in randomized controlled trials (RCT...

The correlates of coach-athlete relationship quality have been the focus of research for over a decade; however, little is known about the mediating and moderating mechanisms underlying these associations. The present study conducted a moderated mediation analysis to examine (a) the mediating role of communication strategies (via COMPASS) on the as...

The present study investigated the role of quality coach–athlete relationships and coaching efficacy on coaches’ well-being and performance. We examined whether coaches’ direct and meta-perspectives of the coach–athlete relationship quality predicted dimensions of coaches’ efficacy, hedemonic and eudaimonic well-being, and coach-related performance...

Aim This study investigates the effects of degree of multilingualism on cognitive functions in adulthood, with focus on episodic memory recall and including measures of verbal fluency as well as global cognition. Design We studied a large population-based cohort cross-sectionally, and we also assessed changes over time through longitudinal measure...

Background and aims The present systematic review and meta-analysis aimed to synthesize the available literature on the relationship between gaming motivations and gaming disorder symptoms. Specifically, to (1) explore what gaming motivation questionnaires and classifications are used in studies on gaming disorder symptoms and (2) investigate the r...

Objectives The purpose of the present study was to examine differences in cognitive and physical performance, affective states, perceived exertion, and physiological responses between trials with cognitive, physical, or combined cognitive and physical load. Design Randomised cross-over trial. Method Highly trained competitive orienteers (n = 15 m...

Esports is an often time-consuming activity that has become increasingly popular with billions of players all over the world. The objective of this study was to investigate if there is a relationship between skill level in the strategy video game Dota 2, a game that places many demands on decision making to be successful, and decision making under...

Objectives To examine bidirectional within- and between-person relations between physical activity and cognitive function across 15 years. Methods Participants (N = 1722, age range 40-85 years, 55% women) were drawn from the Betula prospective cohort study. We included four waves of data. Bivariate latent curve models with structured residuals wer...

An increasing number of people around the world communicate in more than one language, resulting in them having to make decisions in a foreign language on a daily basis. Interestingly, a burgeoning body of literature suggests that people’s decision-making is affected by whether they are reasoning in their native language (NL) or their foreign langu...

The aim of this study was to investigate occupational cognitive complexity of main lifetime occupation in rela�tion to level and 15-year change in episodic memory recall in a sample of older adults (≥ 65 years, n = 780). We used latent growth curve modelling with occupational cognitive complexity (O*NET indicators) as independent variable. Subgroup...

Individual differences in cognitive performance increase with advancing age, reflecting marked cognitive changes in some individuals along with little or no change in others. Genetic and lifestyle factors are assumed to influence cognitive performance in aging by affecting the Journal Pre-proof 3 magnitude and extent of age-related brain changes (i...

Esports are a rapidly growing phenomenon and understanding of factors underlying game performance are therefore of great interest. The present study investigated the influence of satisfaction of basic psychological needs (competence, autonomy, and relatedness), type of motivation (amotivation, external regulation, introjected regulation, identified...

In the present study, we decomposed between- and within-person effects and examined moderators of the longitudinal physical activity-cognition association. Participants (N = 1722) were drawn from the Betula study and we included four waves of data across 15 years. Bayesian multilevel modeling showed that self-reported physical activity did not pred...

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 as...

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...

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 occupat...

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...

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 t...

Emotional stimuli are argued to capture attention and consume attentional resources differently depending on their emotional content. The present study investigates the impact of the automatic detection of unexpected and to‐be‐ignored emotional stimuli on human behavioral responses, and aims to unravel the differences in distraction between two neg...

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...

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 behavi...

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 participan...

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 readi...

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...

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...

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...

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 measur...

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

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...

The longitudinal effects of perceived stress on measures of memory and two other cognitive functions (word fluency, visuospatial ability) in a middle-aged sample (40-60 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 late...
