What Goes Up Apparently Needn't Come Down: Asymmetric Predictions of Ascent and Descent in Rankings

In eight studies, we document an upward mobility bias, or a tendency to predict that a rise in rankings is more likely than a decline. This asymmetry was observed in predictions of classroom performance, NBA and NFL standings, business school rankings, and employee performance rankings. The bias was found for entities people care about and want to see improve their standing, as well as entities in which people are not invested. It appears to result from people's tendency to give considerable weight to a focal agent's intentions and motivation, but to give less weight to the intentions of competitors and other factors that would thwart the focal agent's improvement. We show that this bias is most pronounced for implicit incremental theorists, who believe that performance is malleable (and hence assign more weight to intentions and effort). We discuss implications of this asymmetry for decision making and for an understanding of the underdog bias. Copyright © 2015 John Wiley & Sons, Ltd.     

Inter-individual variability in metacognitive ability for visuomotor performance and underlying brain structures

Metacognition refers to the ability to discriminate between one’s own correct and incorrect decisions. The neurobiological underpinnings of metacognition have mainly been studied in perceptual decision-making. Here we investigated whether differences in brain structure predict individual variability in metacognitive sensitivity for visuomotor performance. Participants had to draw straight trajectories toward visual targets, which could unpredictably deviate around detection threshold, report such deviations when detected, and rate their confidence level for such reports. Structural brain MRI analyses revealed that larger gray-matter volume (GMV) in the left middle occipital gyrus, left medial parietal cortex, and right postcentral gyrus predicted higher deviation detection sensitivity. By contrast, larger GMV in the right prefrontal cortex but also right anterior insula and right fusiform gyrus predicted higher metacognitive sensitivity. These results extend past research by linking metacognitive sensitivity for visuomotor behavior to brain areas involved in action agency (insula), executive control (prefrontal cortex) and vision (fusiform).     

Effective coordination in medical emergency teams: The moderating role of task type

Coordination in health care action teams is an important factor in clinical performance and patient safety. Implementing a high-fidelity in situ simulation study, we investigated the performance-relevant effects of task distribution, provide information without request (PIWR) and closed-loop communication (CLC) in 68 medical emergency teams (METs) composed of fully qualified clinicians. We differentiated between two task types: algorithm-driven and knowledge-driven tasks. We assigned two different emergency tasks to each task type. We proposed not only a direct relationship between the three coordination behaviours and clinical performance, but also a moderating role for the type of task. Only CLC was related to performance and also moderated by task type. There was no relationship between the coordination behaviours task distribution and PIWR and performance. We discuss the differential effects of the three coordination behaviours on performance and emphasize the importance of the task in team research. In particular, we highlight theoretical and practical implications.     

Extraversion and job performance: How context relevance and bandwidth specificity create a non-linear,positive, and asymptotic relationship

The personality factor of extraversion has been associated with performance in some occupations (e.g., sales), and it has been one of the most consistent personality predictors of leadership. Recent research indicates that extraversion could have a non-linear relation with performance. At the same time, many researchers have contended that scholars should utilize measures of personality narrower than factors and that the bandwidth and relevance of personality should fit both the criterion and the context of a study. We argue and find that by examining an aspect of extraversion (i.e., social potency) in a particular vocational context (i.e., enterprising job demands), non-linear, asymptotic (diminishing marginal benefits) effects will be demonstrated on a relevant type of performance (i.e., enterprising job performance). We review implications, limitations, and avenues for future research.     

Emergent Power Hierarchies and Group Performance

In newly formed groups, informal hierarchies emerge automatically and readily. In this study, we argue that emergent group hierarchies enhance group performance (Hypothesis 1) and we assume that the more the power hierarchy within a group corresponds to the task‐competence differences of the individual group members, the better the group performs (Hypothesis 2). Twelve three‐person groups and 28 four‐person groups were investigated while solving the Winter Survival Task. Results show that emerging power hierarchies positively impact group performance but the alignment between task‐competence and power hierarchy did not affect group performance. Thus, emergent power hierarchies are beneficial for group performance and although they were on average created around individual group members' competence, this correspondence was not a prerequisite for better group performance.     

The translation and validation of the Mini‐K scale in Japanese

The purpose of this study was to validate the 20‐item Mini‐K scale, which is the short form of the Arizona Life History Battery, as translated into Japanese. Two samples of Japanese adults (N = 2000; 50.0% men; Mage = 40.9 for the first survey; N = 400; 50.0% men; Mage = 42.2 for the second survey) completed a web‐based questionnaire, including the Japanese translation of the Mini‐K. The results showed that the psychometric properties of the Japanese Mini‐K scale were comparable to those of the original English version. The scale had good reliability based on Cronbach's α and McDonald's ω. Convergent validity was demonstrated by the correlation between the Mini‐K scores and life history indicators. In addition, the Mini‐K score was related to both personality and psychosomatic health. The translated scale provides a valid and reliable instrument in Japanese that measures human life‐history strategy.     

Validity of the German Test Anxiety Inventory (TAI‐G) in an Australian sample

Test anxiety (TA) is a prevalent issue among students that can result in deleterious consequences, such as underachievement. However, a contemporary measure that has been validated for use with Australian students seems to be lacking. This study, therefore, investigated the suitability of the German Test Anxiety Inventory (TAI‐G) for use with Australian university students. While the original TAI‐G contains 30 items and was designed to measure four factors (worry, emotionality, interference, and lack of confidence), differing factorial models have been supported in the literature using either the original or a shortened 17‐item version of the measure. These differing TAI‐G models were tested and compared in the current study via confirmatory factor analysis using 224 Australian university students. As expected, results supported the superior fit of the 17‐item four‐factor model. Additionally, the convergent validity of the measure was supported since measures of self‐esteem, self‐efficacy, and general anxiety were all found to correlate significantly with the TAI‐G in the hypothesised directions. Finally, the finding that all of the TAI‐G subscales had acceptably high reliabilities led to the conclusion that the 17‐item TAI‐G is a valid and reliable measure of TA in an Australian university population.     

The effects of goal setting on rugby performance

Goal-setting effects on selected performance behaviors of 5 collegiate rugby players were assessed over an entire competitive season using self-generated targets and goal-attainment scaling. Results suggest that goal setting was effective for enhancing task-specific on-field behavior in rugby union.     

Autonomy and Nondefensiveness

Three experimental studies tested whether a priming procedure intended to activate an autonomy orientation would lead to nondefensiveness and enhanced performance, whether activated control orientation would lead to higher defense and impaired performance, and whether activated impersonal orientation would lead to the greatest defense and worst performance. Study 1 showed that autonomy-primed participants report lower desire for escape compared to control-primed, and that impersonally-primed showed most desire to escape. In Study 2, autonomy-primed participants showed the least self-serving bias, control-primed were in the middle, and impersonally-primed participants showed the most. In Study 3, rowers autonomy-primed showed the least self-handicapping and best performance, control-primed showed moderate levels, and impersonally-primed showed the most self-handicapping and worst performance. Results are discussed in terms of motivation orientation, defensiveness, and performance.

Effects of guided notes versus completed notes during lectures on college students' quiz performance

We compared the effects of guided lecture notes versus completed lecture notes on pre- to postlecture improvements in quiz performance across two sections of a college course. The results of a counterbalanced multielement design did not reveal consistent differences between the two note formats on students' mean quiz scores. However, fewer errors occurred on complex (analysis-level) quiz questions in the guided notes condition than in the completed notes condition.
