The two sides of competition: Competition‐induced effort and affect during intergroup versus interindividual competition

Competition strongly affects individual effort and performance for both individuals and groups. Especially in work settings, these effort gains might come at the cost of individual well‐being. The present study tested whether competition increases both effort (as indicated by task performance) and stress (in terms of cardiovascular reactivity and affective response), and whether this effect is further qualified by the type of competition (interindividual vs. intergroup), using a cognitive computer‐based task and a 2 (Group: Yes, No) × 2 (Competition: Yes, No) × 2 (Gender) factorial design (N= 147). All participants either worked as a representative of a group or as an individual, and were offered performance‐related incentives distributed in a lottery. In the competition conditions, participants were informed that they competed with someone else, and that only the winning person/team would take part in the lottery. Consistent with expectations, competition increased both individual effort and cardiovascular reactivity compared to non‐competitive work. Moreover, for female participants, intergroup competition triggered increased effort and more positive affect than interindividual competition. Aside from documenting costly side‐effects of competition in terms of stress, this study provides evidence for a stress‐related explanation of effort gains during intergroup competition as compared to interindividual competition.     

French Validation of the Overexcitability Questionnaire 2: Psychometric Properties and Factorial Structure

Overexcitability corresponds to an overall response to stimulations in 5 domains: psychomotor, sensual, intellectual, imaginational, and emotional. The aim of this study was to develop a French version of the Overexcitability Questionnaire 2 (OEQ2) and to expand its psychometric properties. Two studies were conducted: one with a sample of 474 adolescents and another with a sample of 436 adults. Internal consistency, factorial structure, and validity (correlations with intelligence, personality, and alexithymia) were examined. The French OEQ2 showed satisfactory psychometric properties, thus advocating for its use in further research on overexcitability and in clinical practice.     

Why walkers slip: shine is not a reliable cue for slippery ground

In a series of four studies, we investigated the visual cues that walkers use to predict slippery ground surfaces and tested whether visual information is reliable for specifying low-friction conditions. In Study 1, 91% of participants surveyed responded that they would use shine to identify upcoming slippery ground. Studies 2-4 confirmed participants' reliance on shine to predict slip. Participants viewed ground surfaces varying in gloss, paint color, and viewing distance under indoor and outdoor lighting conditions. Shine and slip ratings and functional walking judgments were related to surface gloss level and to surface coefficient of friction (COF). However, judgments were strongly affected by surface color, viewing distance, and lighting conditions--extraneous factors that do not change the surface COF. Results suggest that, although walkers rely on shine to predict slippery ground, shine is not a reliable visual cue for friction. Poor visual information for friction may underlie the high prevalence of friction-related slips and falls.     

The Attentional Focus of Expert Golfers in Training and Competition: A Naturalistic Investigation

This study explored the attentional focus of expert golfers using a naturalistic approach. Eight male professional golfers were filmed in two contexts (training and competition). Self-confrontation interviews based on the video were conducted immediately afterwards. Qualitative data analyses showed that golfers used various attentional foci. Foci were classified according to their content and their characteristics. Golfers adapted their attentional foci to the context. They used sequences of attentional foci and moved from one attentional focus to another when they prepared, executed, or evaluated their shot. Future research on attentional focus of expert athletes should study the phenomenon over time.
