Introduction: With the increase of age, a physical decline is generally observed, due to an inevitable biological process (e.g., Milanović et al., 2013).

Thus, this study examined whether aging stereotypes in the physical domain are associated with walking speed, muscular strength, and balance through subjective...

Lorsqu'un stéréotype négatif à l'encontre d'un groupe est induit, une baisse de performance de ce groupe est généralement observée. La majorité de ces études ont observé cet effet sur des tâches techniques [1]. Cependant, lors de tâches non-techniques, l'induction de ce même stéréotype résulte en une amélioration de la performance [2]. Les...

IntroductionAccording to the stereotype threat model (Steele, 1997), people can underperform on a task when thinking about the negative performance expectations of their group. Based on this theory, many studies showed a negative influence of stereotypes on performance during motor tasks such as basketball shooting (e.g., Hively & El-Alayli,...
