Full-text available
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...
Article
Full-text available
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...

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...
Article
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...
Article
Full-text available
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...
Article
Full-text available
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...
Article
Full-text available
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...
Article
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...
Article
Full-text available
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...
Article
Full-text available
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...

Full-text available
The main objective of this study was to investigate 50 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 modelling of cognitive measures with baseline...
Article
It has been suggested that deviance distraction is caused by unexpected sensory events in the to-be-ignored stimuli violating the cognitive system's predictions of incoming stimuli. The majority of research has used methods where the to-be-ignored expected (standards) and the unexpected (deviants) stimuli are presented within the same modality. Les...
Article
Full-text available
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...
Article
Full-text available
Recent findings indicate that bilingualism delay the onset of dementia. Using data from the Betula longitudinal cohort study on memory, health and aging ( www.betula.su.se ) the issue of a possible protective effect of bilingualism was addressed. Monolingual ( n = 736) and bilingual ( n = 82) participants (≥ 60 years) without dementia at inclusion...
Article
Research of the distractor value of hearing the own name has shown that this self-referring stimulus captures attention in an involuntary fashion and create distraction. The behavioral studies are few and the outcomes are not always clear cut. In this study the distraction by own name compared to a control name was investigated by using a cross-mod...
Article
Full-text available
Typically, studies of cognitive advantages in bilinguals have been conducted previously by using executive and inhibitory tasks (e.g. Simon task) and applying cross-sectional designs. This study longitudinally investigated bilingual advantages on episodic memory recall, verbal letter and categorical fluency during the trajectory of life. Monolingua...
Article
Full-text available
Previous research has indicated that sensory sensitivity/intolerance to a specific modality may be part of a more general environmental hypersensitivity, and possibly mediated by stress. This study investigated the relationship between noise sensitivity, perceived stress, and odor sensitivity in a group of men. A quasi-experimental design was used....
Article
Full-text available
Unexpected task-irrelevant changes in the auditory or visual sensory channels have been shown to capture attention in an ineluctable manner and distract participants away from ongoing auditory or visual categorization tasks. We extend the study of this phenomenon by reporting the first within-participant comparison of deviance distraction in the ta...
Article
Full-text available
Sounds deviating from an otherwise repeated stream of task-irrelevant auditory stimuli (deviant sounds among standard sounds) are known to capture attention and impact negatively on ongoing behavioral performance (behavioral oddball distraction). Traditional views consider such distraction as the ineluctable consequence of the deviant sounds' low p...
Article
Full-text available
Both the behavioural and subjective impacts of single-word spoken warnings were examined. Behaviourally, the effect of infrequently occurring warnings was studied through their disruptive impact on a visually presented serial recall task. In separate experiments, ratings of the same words were elicited. Experiment 1 showed a localized effect of the...
Article
Full-text available
The objective was to study the involuntary capture of attention by spoken words varying in intonation and valence. In studies of verbal alarms, the propensity of alarms to capture attention has been primarily assessed with the use of subjective ratings of their perceived urgency. Past studies suggest that such ratings vary with the alarms' spoken u...
Article
Full-text available
Past research has demonstrated that the occurrence of unexpected task-irrelevant changes in the auditory or visual sensory channels captured attention in an obligatory fashion, hindering behavioral performance in ongoing auditory or visual categorization tasks and generating orientation and re-orientation electrophysiological responses. We report t...
Article
Full-text available
Vehicle drivers are often exposed to noise, whole-body vibration (WBV), and mental loads, but the knowledge of how combined effects from multiple environmental stressors affect mental load and performance is sparse. Studies have shown that the effect of both vibration and noise combined can differ from those of either vibration or noise alone. For...
Article
Unexpected events often distract us. In the laboratory, novel auditory stimuli have been shown to capture attention away from a focal visual task and yield specific electrophysiological responses as well as a behavioral cost to performance. Distraction is thought to follow ineluctably from the sound's low probability of occurrence or, put more simp...
Article
Full-text available
In this article we outline a "sub-process view" of working memory capacity (WMC). This view suggests that any relationship between WMC and another construct (e.g., reading comprehension) is actually a relationship with a specific part of the WMC construct. The parts, called sub-processes, are functionally distinct and can be measured by intrusion e...
Article
The aim of this review is to shed light on a research area that concerns the studies of psychological responses to combined exposures of noise and whole-body vibration (WBV). Vehicle drivers are a group of workers that are often exposed to multiple stressors like noise, WBV and mental loads. Degraded performance because of environmental stressors m...

This study investigated the effects on attention performance after exposure to noise and whole-body vibration in relation to subjective noise sensitivity. Sixteen high and 16 low sensitivity male students, as determined by the Weinstein Noise Sensitivity Questionnaire, participated in a within-subjects experiment. Noise and vibration stimuli simila...
Article
This study investigates the effects of noise and whole-body vibration on saliva cortisol levels and subjectively rated difficulty and stress while performing cognitive tasks. In the first experiment, 24 men completed a logical reasoning task and a short-term memory task while, on separate occasions, being exposed to noise, vibration, combined stimu...
Article
Full-text available
This study investigated if vehicle noise and whole-body vibrations produce negative after-effects on performance in an attention task and on ratings of alertness, difficulty, and annoyance. The task was applied before and after exposure, and after a rest. Participants had degraded performance immediately after exposure in all conditions, but no eff...
Conference Paper
Full-text available
An experimental study with 24 male subjects between 21 and 30 years (X= 25, SD= 2.4) was conducted. The objective was to investigate post-exposure effects in attention performance after exposure to noise, a whole-body vibration, both factors combined and a control condition. Another aim was to explore if participants would have more degraded perfor...
