              <p>Objective : Accurately interpreting emotional states from facial expressions is crucial for effective social interactions. This study investigates age-related differences in interpersonal distance (IPD) regulation and emotion recognition using a virtual reality (VR) environment. We examined how younger and older adults adjust their IPD in response to emotional expressions from virtual agents.Methods : Eighty participants, divided into older adults (OA) and younger adults (YA), took part in the study. Participants were immersed in a VR setup where they engaged in social interactions with happy or angry looking virtual agents. This behavioral task was complemented by a standardized emotion recognition task (ERT).Results : Results showed that both YA and OA preferred larger distances from angry-looking virtual agents compared to happy ones. No significant differences in IPD were found between the age groups. However, older adults were less accurate in recognizingfacial expressions.Conclusion : These findings suggest that older adults can effectively regulate their social distance despite potential challenges in emotion recognition. The study underscores the importance of considering cognitive, perceptual, and motivational factors when examining the dynamics of emotional recognition and interpersonal distance in social contexts.</p>

              <p>Objectif : Interpréter avec précision les états émotionnels à partir des expressions faciales est essentiel pour des interactions sociales efficaces. Cette étude examine les différences liées à l’âge dans la régulation de la distance interpersonnelle (IPD) et la reconnaissance des émotions, en utilisant un environnement de réalité virtuelle (VR). Nous avons étudié la manière dont les jeunes adultes et les adultes plus âgés ajustent leur distance interpersonnelle en réponse aux expressions émotionnelles d’agents virtuels.Méthode : Quatre-vingts participants, répartis en deux groupes — adultes plus âgés (OA) et jeunes adultes (YA) — ont pris part à l’étude. Les participants étaient immergés dans un dispositif de réalité virtuelle où ils interagissaient avec des agents virtuels affichant des expressions de joie ou de colère. Cette tâche comportementale était complétée par un test standardisé de reconnaissance des émotions (ERT).Résultats : Les résultats montrent que les YA comme les OA préféraient maintenir une plus grande distance face à des agents virtuels exprimant la colère que face à ceux exprimant la joie. Aucune différence significative de distance interpersonnelle n’a été observée entre les groupes d’âge. Toutefois, les adultes plus âgés étaient moins précis dans la reconnaissance des expressions faciales.Conclusion : Ces résultats suggèrent que les adultes plus âgés peuvent réguler efficacement leur distance sociale malgré des difficultés potentielles dans la reconnaissance des émotions. L’étude souligne l’importance de prendre en compte les facteurs cognitifs, perceptifs et motivationnels dans l’analyse des dynamiques de reconnaissance émotionnelle et de régulation de la distance interpersonnelle en contexte social.</p>
