Components of task switching: A closer look at task switching and cue switching

Research using the diffusion model to decompose task-switching effects has contributed to a better understanding of the processes underlying the observed effect in the explicit task cueing paradigm: Previous findings could be reconciled with multiple component models of task switching or with an account on compound-cue retrieval/repetition priming. In the present study, we used two cues for each task in order to decompose task-switch and cue-switch effects. Response time data support previous findings that comparable parts of the switching effect can be attributed to cue-switching and task-switching. A diffusion model analysis of the data confirmed that non-decision time is increased and drift rates are decreased in unpredicted task-switches. Importantly, it was shown that non-decision time was selectively increased in task-switching trials but not in cue-switching trials. Results of the present study specifically support the notion of additional processes in task-switches and can be reconciled with broader multiple component accounts.     

Self‐regulation predicts risk‐taking through people's time horizon

In the context of decision‐making research, people's regulatory orientation mode (i.e., assessment and locomotion modes) has been included among the most prominent individual difference variables, which may potentially account for choice behaviour. Thus, the main objective of our experiment was to investigate the relations between habitual use of regulatory mode and risk‐taking through people's time horizon. Risk‐taking was appraised using a behavioural measure (i.e., BART) 1 month following evaluation of habitual use of regulatory mode. The findings revealed a significant negative association between the assessment mode and risk‐taking through individual differences in time horizon.     

Framing (implicitly) matters: The role of religion in attitudes toward immigrants and Muslims in Denmark

Denmark is currently experiencing the highest immigration rate in its modern history. Population surveys indicate that negative public attitudes toward immigrants actually stem from attitudes toward their (perceived) Islamic affiliation. We used a framing paradigm to investigate the explicit and implicit attitudes of Christian and Atheist Danes toward targets framed as Muslims or as immigrants. The results showed that explicit and implicit attitudes were more negative when the target was framed as a Muslim, rather than as an immigrant. Interestingly, implicit attitudes were qualified by the participants’ religion. Specifically, analyses revealed that Christians demonstrated more negative implicit attitudes toward immigrants than Muslims. Conversely, Atheists demonstrated more negative implicit attitudes toward Muslims than Atheists. These results suggest a complex relationship between religion, and implicit and explicit prejudice. Both the religious affiliation of the perceiver and the perceived religious affiliation of the target are key factors in social perception.     

Effect of aerobic training on inter-arm coordination in highly trained swimmers

The effect of three months of aerobic training on spatio-temporal and coordination parameters was examined during a swim trial at maximal aerobic speed. Nine male swimmers swam a 400-m front crawl at maximal speed twice: in trial 1, after summer break, and trial 2, after three months of aerobic training. Video analysis determined the stroke (swimming speed, stroke length, and stroke rate) and coordination (Index of Coordination and propulsive phase duration) parameters for every 50-m segment. All swimmers significantly increased their swimming speed after training. For all swimmers except one, stroke length increased and stroke rate remained constant, whereas the Index of Coordination and the propulsive phase duration decreased (p < .05). This study suggests that aerobic training developed a greater force impulse in the swimmers during the propulsive phases, which allowed them to take advantage of longer non-propulsive phases. In this case, catch-up coordination, if associated with greater stroke length, can be an efficient coordination mode that reflects optimal drag/propulsion adaptation. This finding thus provides new insight into swimmers’ adaptations to the middle-distance event.     

Compensation method affects risk-taking in the Balloon Analogue Risk Task

Different participant compensation methods may have discrepant effects on decision-making in behavioral measures of risk-taking. Participants in clinical samples tend to receive session-based payment (often in conjunction with decision-based payment), whereas participants in student samples generally receive decision-based payment or no payment at all. This study examined the effect of different methods of participant payment on a behavioral measure of individual differences in risk-taking. Participants completed the Balloon Analogue Risk Task (BART) as well as questionnaire measures of sensation-seeking and impulsivity. Participants who received session-based payment engaged in significantly greater risk-taking in the BART compared to those who were paid based on their decisions and those who were not paid at all (i.e., those who were only compensated with course credit). These effects were not influenced by age, gender, sensation-seeking or impulsivity. These findings provide evidence that different compensation methods significantly influence participants’ risk-taking propensity as measured by the BART.     

Object-based and egocentric mental rotation performance in older adults: The importance of gender differences and motor ability

In this study, mental rotation performance was assessed in both an object-based task, human figures and letters as stimuli, and in an egocentric-based task, a human figure as a stimulus, in 60 older persons between 60 and 71 years old (30 women, 30 men). Additionally all participants completed three motor tests measuring balance and mobility. The results show that the reaction time was slower for letters than for both human figure tasks and the mental rotation speed was faster over all for egocentric mental rotation tasks. Gender differences were found in the accuracy measurement, favoring males, and were independent of stimulus type, kind of transformation, and angular disparity. Furthermore, a regression analysis showed that the accuracy rate for object-based transformations with body stimuli could be predicted by gender and balance ability. This study showed that the mental rotation performance in older adults depends on stimulus type, kind of transformation, and gender and that performance partially relates to motor ability.     

Embodiment and affect in research collaborations

This article communicates the emotional experiences of two researchers on a collaborative project. Drawing on our emotional journeys related to an inter-disciplinary research project, we present narratives and poems to reflect specific research moments. These moments reflect our embodied experiences and creative responses to our work, and the wider research project. In so doing, we use the theoretical tools of Bourdieu to reflect on how the fields of practice (and thus habitus) we each bring to a research project can have direct emotional consequences. Indeed, we suggest that being aware of our emotional responses can lead us toward a better understanding of how collaborations can cause tensions between fields of practice.     

A shield against distraction

In this paper, we apply the basic idea of a trade-off between the level of concentration and distractibility to test whether a manipulation of task difficulty can shield against distraction. Participants read, either in quiet or with a speech noise background, texts that were displayed either in an easy-to-read or a hard-to-read font. Background speech impaired prose recall, but only when the text was displayed in the easy-to-read font. Most importantly, recall was better in the background speech condition for hard-to-read than for easy-to-read texts. Moreover, individual differences in working memory capacity were related to the magnitude of disruption, but only in the easy-to-read condition. Making a task more difficult can sometimes facilitate selective attention in noisy work environments by promoting focal-task engagement.     

Will students pass a competitive exam that they failed in their dreams?

We tested whether dreams can anticipate a stressful exam and how failure/success in dreams affect next-day performance. We collected information on students’ dreams during the night preceding the medical school entrance exam. Demographic, academic, sleep and dream characteristics were compared to the students’ grades on the exam. Of the 719 respondents to the questionnaire (of 2324 total students), 60.4% dreamt of the exam during the night preceding it. Problems with the exam appeared in 78% of dreams and primarily involved being late and forgetting answers. Reporting a dream about the exam on the pre-exam night was associated with better performance on the exam (p = .01). The frequency of dreams concerning the exam during the first term predicted proportionally higher performance on the exam (R = 0.1, p = .01). These results suggest that the negative anticipation of a stressful event in dreams is common and that this episodic simulation provides a cognitive gain.
