Existing research has revealed key factors influencing mathematical flexibility, defined as the capacity to understand, generate, and apply a variety of strategies in solving mathematical problems. However, there is currently a lack of an integrated theoretical framework to systematically consolidate various sources of individual differences in…

Although children display strong individual differences in emotion expression, they also engage in emotional synchrony or reciprocity with interaction partners. To understand this paradox between trait-like and dyadic influences, the goal of the current study was to investigate children's emotion expression using a Social Relations Model (SRM)…

Snyder's hope theory depicts hope, through the frame of positive psychology, as a cognitive construct with the perceived sense of goal-directed, pathways, and agency thinking (Snyder et al., 1991). Hope levels have been measured in various countries; however, no research to date focused on Haitians. This study, conducted in Petit-Goâve, Haiti,…

This study used idiodynamic methodology to investigate the dynamics of second language (L2) learners' foreign language anxiety (FLA) and foreign language enjoyment (FLE), and the details of emotion regulation (ER) directed at managing these emotions, in pair- and group-work speaking tasks performed by 10 advanced English-as-a-foreign-language…

Pragmatic abilities are fundamental to successful language use and learning. Individual differences studies contribute to understanding the psychological processes involved in pragmatic reasoning. Small sample sizes, insufficient measurement tools, and a lack of theoretical precision have hindered progress, however. Three studies addressed these…

People are able to perceive emotions in the eyes of others and can therefore see emotions when individuals wear face masks. Research has been hampered by the lack of a good test to measure basic emotions in the eyes. In two studies respectively with 358 and 200 participants, we developed a test to see anger, disgust, fear, happiness, sadness and…

Although research on team performance-prove goal orientation (TPPGO) has flourished, there remains a scarcity of studies investigating its impact on individual performance. Drawing upon transactional stress theory, our study aims to explore the dual nature of the influence exerted by TPPGO on employee creative performance. Employing a multi-level…

Anxiety-driven counterfactual thinking can be a slippery slope. Building on the premise that both positive and negative emotions can impact creativity, the present study examines how trait anxiety, optimism, and other mental health factors like therapy experience shape outputs in divergent thinking (DT) tasks. Using an online sample (N = 647), the…

Engagement and willingness to communicate (WTC) are crucial elements for second language (L2) learning. However, little is written about whether L2 learners demonstrate heterogeneous patterns of engagement and WTC in the classroom. This study aims to identify intraindividual differences in these two constructs and examine the roles of eight…

Entrepreneurship is a powerful tool that reduces unemployment, boosts economic growth, and promotes innovation and social change.
