On the link between mind wandering and task performance over time

Here we test the hypothesis that fluctuations in subjective reports of mind wandering over time-on-task are associated with fluctuations in performance over time-on-task. In Study 1, we employed a singleton search task and found that performance did not differ prior to on- and off-task reports, nor did individual differences in mind wandering predict differences in performance (so-called standard analytic methods). Importantly however, we find that fluctuations in mind wandering over time are strongly associated with fluctuations in behavior. In Study 2, we provide a replication of the relation between mind wandering and performance over time found in Study 1, using a Flanker interference task. These data indicate (1) a tight coupling between mind wandering and performance over time and (2) that a temporal-analytic approach can reveal effects of mind wandering on performance in tasks where standard analyses fail to do so. The theoretical and methodological implications of these findings are discussed.     

Understanding perfectionism and depression in an adult clinical population: Is outcome expectancy relevant to psychological functioning?

Perfectionism is a personality trait defined by high standards of performance, which has been identified as a risk factor for major depressive disorder (MDD). The present study examined if outcome expectancy involved in perfectionism differs for individuals with depression compared to non-depressed controls, and how outcome expectancy relates to depression symptoms. This study included 49 depressed and 42 non-depressed participants. Perfectionism and depression severity were measured via self-report instruments. This study is the first to provide preliminary evidence that outcome expectancies involved in perfectionism may be related to psychological functioning in depression. Individuals with depression demonstrated higher negative and lower positive outcome expectancies associated with perfectionism compared to non-depressed participants. Perfectionism outcome expectancies are also related to depression severity and symptoms. Future research should prospectively investigate relationships of outcome expectancy involved in perfectionism in individuals at risk for depression.     

Quantification of upper limb kinetic asymmetries in front crawl swimming

This study aimed at quantifying upper limb kinetic asymmetries in maximal front crawl swimming and to examine if these asymmetries would affect the contribution of force exertion to swimming performance. Eighteen high level male swimmers with unilateral breathing patterns and sprint or middle distance specialists, volunteered as participants. A load-cell was used to quantify the forces exerted in water by completing a 30 s maximal front crawl tethered swimming test and a maximal 50 m free swimming was considered as a performance criterion. Individual force–time curves were obtained to calculate the mean and maximum forces per cycle, for each upper limb. Following, symmetry index was estimated and breathing laterality identified by questionnaire. Lastly, the pattern of asymmetries along the test was estimated for each upper limb using linear regression of peak forces per cycle. Asymmetrical force exertion was observed in the majority of the swimmers (66.7%), with a total correspondence of breathing laterality opposite to the side of the force asymmetry. Forces exerted by the dominant upper limb presented a higher decrease than from the non-dominant. Very strong associations were found between exerted forces and swimming performance, when controlling the isolated effect of symmetry index. Results point that force asymmetries occur in the majority of the swimmers, and that these asymmetries are most evident in the first cycles of a maximum bout. Symmetry index stood up as an influencing factor on the contribution of tethered forces over swimming performance. Thus, to some extent, a certain degree of asymmetry is not critical for short swimming performance.     

Performance slumps in sport: A systematic review

This systematic review explored the under-researched experience of performance slumps in sport with four objectives: (i) review definitions of a performance slump; (ii) identify known causes of a performance slump; (iii) identify the symptoms athletes present when in a performance slump; and (iv) review approaches used to combat a slump in performance. Literature searches into three databases (PsychARTICLES, PsychINFO and SPORTDiscus) resulted in the inclusion of quantitative (n = 14) and qualitative (n = 4) empirical research studies. The findings were thematically analysed and narratively synthesised. Results showed that: (i) definitions of a performance slump vary; (ii) perceived expectations for success and athletes attributing poor performance to something about themselves have been empirically verified as performance slump causes; (iii) during a slump, athletes might display a range of emotional and psychological symptoms and/or adopt skill-focused attention; and (iv) athletes reported several ways of coping with a performance slump, and research has offered succeeding under pressure as a potential route out of a slump. This systematic review highlights the need for an empirical investigation of the performance slump phenomenon. Future studies should be directed towards understanding the prominent symptoms athletes experience during the slump, so that cause, context, competitor and symptomatic dependant intervention strategies can be designed.     

Stereotype Lift

When a negative stereotype impugns the ability or worth of an outgroup, people may experience stereotype lift—a performance boost that occurs when downward comparisons are made with a denigrated outgroup. In a meta-analytic review, members of non-stereotyped groups were found to perform better when a negative stereotype about an outgroup was linked to an intellectual test than when it was not (d=.24,p<.0001). Notably, people appear to link negative stereotypes to evaluative tests more or less automatically. Simply presenting a test as diagnostic of ability was thus sufficient to induce stereotype lift. Only when negative stereotypes were explicitly invalidated or rendered irrelevant to the test did the lift effect disappear.     

The effects of the presence of others during a rowing exercise in a virtual reality environment

ObjectivesThe aim of the study was to test the performance, motivational, and affective impact of aerobic exercise within an immersive virtual reality environment experienced alone or with another individual.DesignSixty female participants aged 18–30 years were assigned to one of three conditions: no virtual reality (NVR), individual virtual reality (IVR), or companion virtual reality (CVR).MethodParticipants completed 9 min of self-paced rowing on an ergometer without any visual input or performance feedback (NVR), individually within a virtual reality environment (IVR), or within a virtual reality environment that included a companion depicted as an avatar (CVR).ResultsThe two virtual reality groups rowed a further distance and at a higher power output than the NVR group. Furthermore, the CVR group outperformed the IVR group in distance and had a higher heart rate. Participants in the virtual reality groups did not perceive themselves to be exerting more physical effort and rated the task as more enjoyable than participants in the NVR group.ConclusionsVirtual reality improves performance and the affective response to aerobic exercise, and performance effects are further enhanced by the presence of others in the virtual environment.     

Consequences of prosocial and antisocial behavior for the recipient

Statement of problemAlthough studies have examined antecedents of prosocial and antisocial behaviors in sport, little is known about the potential consequences of these behaviors for the recipient. In this research, we examined: (a) whether teammate prosocial and antisocial behaviors are related to athletes’ effort, performance, enjoyment and anger during a match and the mediating role of enjoyment and anger (Studies 1 and 2); and (b) whether prosocial and antisocial behaviors are related to commitment to play for one’s team and whether enjoyment and performance mediate these relationships (Study 2).MethodRight after a game, football/soccer (N = 203; Study 1) and basketball (N = 281; Study 2) players completed a multi-section questionnaire measuring the aforementioned variables.ResultsProsocial teammate behavior was positively related to effort, performance, and enjoyment, and enjoyment mediated the relationship between prosocial teammate behavior and effort and performance; prosocial teammate behavior was also positively related to commitment directly and indirectly through enjoyment and performance. Antisocial teammate behavior was positively related to anger and negatively related to effort and performance. Anger and performance mediated the effects of antisocial teammate behavior on effort and commitment, respectively.ConclusionsOur findings demonstrate the importance of acting prosocially and not acting antisocially toward one’s teammates and have implications for enjoyment, effort, performance, and commitment in sport.
