In the context of a sports match,the goal to win is most important,right? Suggestive evidence for a hierarchical achievement goal system

When evaluating one’s own or others’ performances, there is a strong tendency to rely on social comparison information. Remarkably, however, the extant achievement goal research suggests that the prevalence of other-based goals is very low, also in sport contexts. In the present research, we argue and demonstrate that in the context of a sports match: (1) most athletes’ overarching achievement goal is an other-based approach goal (i.e., the goal to win), and (2) athletes with an overarching other-based approach goal also rely on self-based criteria (referring to one’s personal performance trajectory) and task-based criteria (referring to the absolute demands of the task). Survey data was collected among 647 competitive korfball players (69.4% women), ranging in age from 16 to 56 years. As expected, for most athletes (51.6%), to win matches was their overarching achievement goal, and pursuing self-based and task-based approach goals added to their competence satisfaction. In such a hierarchical achievement goal system, subordinate goals likely help athletes to increase their awareness of what actions and means facilitate their focal objective: Coming out victorious.     

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.     

Sleep interventions for performance,mood and sleep outcomes in athletes: A systematic review and meta-analysis

Sleep is fundamental to sports performance and other health outcomes such as mental wellbeing. This systematic review explored the effects of sleep interventions implemented among athletes on performance, sleep, and mood outcomes. Five databases were searched, returning 5996 records for screening. Of these, 27 articles met the inclusion criteria (16 controlled deigns, 11 uncontrolled; athletes n = 617; male n = 432, female n = 93, non-binary/other n = 0 or not reported n = 92). Narrative synthesis of all studies based on intervention type suggested that sleep hygiene, assisted sleep, and sleep extension interventions may be associated with improved sleep, performance, and mood outcomes. Twelve controlled trials were eligible for quantitative meta-analysis, investigating the effect of sleep interventions on athlete sleep, performance, and negative affect, compared to controls post-intervention. Utilizing random-effects meta-analyses, sleep interventions improved subjective sleep quality (g = 0.62, 95% CI [0.21, 1.02]), reduced sleepiness (g = 0.81, 95% CI [0.32, 1.30]) and decreased negative affect (g = 0.63, 95% CI [0.27, 0.98]), but did not appear to influence subjective sleep duration. No effects were identified for objective sleep measures (e.g., actigraphy), or aerobic/anaerobic performance indices. While sleep interventions may offer some benefit to athletes, caution is warranted given limitations of the extant research relating to small, non-representative studies with methodological concerns.     

When should I trust my gut? Linking domain expertise to intuitive decision-making effectiveness

Despite a growing body of scholarship on the concept of intuition, there is a scarcity of empirical research spotlighting the circumstances in which intuitive decision making is effective relative to analytical decision making. Seeking to address this deficiency, we conducted two laboratory studies assessing the link between domain expertise (low versus high) and intuitive decision-making effectiveness. These studies involved non-decomposable tasks across divergent expertise domains: basketball in Study 1 and designer handbag authentication in Study 2. Across both studies, and consistent with our overarching hypothesis, we found that the effectiveness of intuition relative to analysis is amplified at a high level of domain expertise. Taken together, our results demonstrate the importance of domain expertise in intuitive decision making and carry a number of theoretical and practical implications.     

风险取向类型与爱荷华赌博任务成绩的影响

神经科学领域的研究者们设计了测量情感决策的经典爱荷华赌博任务并提出了体细胞标记假说来解释其研究结果,但迄今为止这一假说还没有得到一致认可。许多研究提出了可能影响爱荷华赌博任务成绩的其他因素。本研究试图在前人研究的基础上采用实验法探讨风险取向类型这一人格因素是否影响正常个体的爱荷华赌博任务成绩。实验结果显示,不同风险取向类型的个体在爱荷华赌博任务中的成绩和表现截然不同。典型风险趋向型个体在爱荷华赌博任务中的表现类似于某些神经系统患者,倾向于更多地选择不利纸牌,其任务成绩显著差于典型风险回避型个体。这一研究结果表明：风险取向类型是影响正常个体爱荷华赌博任务成绩的重要因素之一。     

A naturalistic study of prospective memory in preschoolers: The role of task interruption and motivation

We conducted two naturalistic experiments to investigate preschoolers’ development of event-based prospective memory (PM) and to examine the effects of motivation and interruption of an ongoing task. Children aged 2–6 years were asked to perform familiar PM tasks while engaged in their habitual kindergarten play. PM performance improved systematically across the preschool years. The type of PM response (motor or verbal) did not affect performance. High motivation was necessary for 2-year-olds to perform well, and it remained an important factor that increased performance across the entire preschool age range. The need to interrupt an ongoing activity decreased performance in 3-, 4-, and 5-year-olds, but not in children aged 2 or 6 years. The pattern of results is consistent with explanations for interruption effects that highlight the role of inhibitory control.     

Attention control: Relationships between self-report and behavioural measures,and symptoms of anxiety and depression

Previous research has demonstrated differences in processing between fear-relevant stimuli, such as snakes and spiders, and non-fear-relevant stimuli. The current research examined whether non-fear-relevant animal stimuli, such as dogs, birds and fish, were processed like fear-relevant stimuli following aversive learning. Pictures of a priori fear-relevant animals, snakes and spiders, were evaluated as negative in affective priming and ratings and were preferentially attended to in a visual search task. Pictures of dogs, birds and fish that had been trained as CS+ in an aversive conditioning design were evaluated more negatively and facilitated dot probe detection relative to CS? pictures. The current studies demonstrated that stimuli viewed as positive prior to aversive learning were negative and were preferentially attended to after a brief learning episode. We propose that aversive learning may provide a mechanism for the acquisition of stimulus fear relevance.     

Delayed reconfiguration of a non-emotional task set through reactivation of an emotional task set in task switching: an ageing study

ABSTRACT

In our everyday life, we frequently switch between different tasks, a faculty that changes with age. However, it is still not understood how emotion impacts on age-related changes in task switching. Using faces with emotional and neutral expressions, Experiment 1 investigated younger (n?=?29; 18–38 years old) and older adults’ (n?=?32; 61–80 years old) ability to switch between an emotional and a non-emotional task (i.e. responding to the face's expression vs. age). In Experiment 2, younger and older adults also viewed emotional and neutral faces, but switched between two non-emotional tasks (i.e. responding to the face's age vs. gender). Data from Experiment 1 demonstrated that switching from an emotional to a non-emotional task was slower when the expression of the new face was emotional rather than neutral. This impairment was observed in both age groups. In contrast, Experiment 2 revealed that neither younger nor older adults were affected by block-wise irrelevant emotion when switching between two non-emotional tasks. Overall, the findings suggest that task-irrelevant emotion can impair task switching through reactivation of the competing emotional task set. They also suggest that this effect and the ability to shield task-switching performance from block-wise irrelevant emotion are preserved in ageing.     

Emotion regulation and risk taking: Predicting risky choice in deliberative decision making

Only very recently has research demonstrated that experimentally induced emotion regulation strategies (cognitive reappraisal and expressive suppression) affect risky choice (e.g., Heilman et al., 2010). However, it is unknown whether this effect also operates via habitual use of emotion regulation strategies in risky choice involving deliberative decision making. We investigated the role of habitual use of emotion regulation strategies in risky choice using the “cold” deliberative version of the Columbia Card Task (CCT; Figner et al., 2009). Fifty-three participants completed the Emotion Regulation Questionnaire (ERQ; Gross & John, 2003) and—one month later—the CCT and the PANAS. Greater habitual cognitive reappraisal use was related to increased risk taking, accompanied by decreased sensitivity to changes in probability and loss amount. Greater habitual expressive suppression use was related to decreased risk taking. The results show that habitual use of reappraisal and suppression strategies predict risk taking when decisions involve predominantly cognitive-deliberative processes.     

Assessing visual search performance differences between Transportation Security Administration Officers and nonprofessional visual searchers

Some visual searches depend upon accuracy (e.g., radiology, airport security screening), and it is important for both theoretical and applied reasons to understand what factors best predict performance. The current study administered a visual search task to both professional (Transportation Security Administration Officers) and nonprofessional (members of Duke University) searchers to examine group differences in which factors predict accuracy. Search speed—time taken to terminate search—was the primary predictor for nonprofessional searchers (accounting for 59% of their accuracy variability) and for the least experienced professional searchers (37% of variability). In contrast, consistency—how similarly (in terms of search speed) an individual spent searching from trial to trial—was the primary predictor for the most experienced professional visual searchers (39% of variability). These results inform cognitive theory by illuminating factors that differentially affect search performance between participants, and real-world issues by identifying search behaviours (consistency in particular) important to experienced professional searchers.
