Biographie

Mes recherches s’articulent autour des processus d’exclusion sociale et de stigmatisation sur la santé, les comportements et les trajectoires identitaires.

Après un doctorat à l’Université Paris Nanterre consacré à la régulation de l’exclusion sociale et de la discrimination, j’ai poursuivi mes recherches dans le cadre de plusieurs expériences postdoctorales à l’Université Savoie Mont Blanc et à Université Paris Cité, autour des interventions en santé mentale et de la stigmatisation de l’autisme en contexte universitaire. 

Actuellement, je développe un axe de recherche consacré à la stigmatisation du handicap psychique et à ses effets sur l’engagement dans les activités physiques et sportives. Plus spécifiquement, j’étudie comment les expériences de stigmatisation peuvent favoriser l’internalisation des stéréotypes associés au handicap, et dans quelle mesure cette internalisation constitue un frein à l’engagement dans les activités physiques adaptées (APA) et les dispositifs de sport-santé. Je m’intéresse également à la manière dont ces dispositifs peuvent contribuer au développement de nouvelles identités sociales et constituer une ressource face à la stigmatisation. Enfin, mes travaux explorent le rôle des vulnérabilités sociales et des dynamiques identitaires dans les trajectoires de radicalisation masculiniste chez les hommes en milieu sportif. 

Ces recherches mobilisent des approches expérimentales, quantitatives, et qualitatives.

  • The effect of intergroup ostracism on identity and affective responses: Exploring the role of perceived discrimination.

    <div><p>Introduction: While the effects of interindividual ostracism have been widely studied, the effects of intergroup ostracism have received less attention. In this study, we are interested in the consequences of intergroup ostracism on perceived discrimination, identity responses and well-being. Method: A total of 110 participants in psychology were randomly assigned to three ostracism experiences. Participants either shared ostracism with an ingroup member, with an outgroup member, or did not share ostracism. Results: The results show that ostracism, whether shared or not, increases identification but does not increase perceived entitativity of the group. The results also show that when ostracism is shared with an outgroup member -the condition with less perceived discrimination-participants indicate more psychological need satisfaction. Discussion: Taken together, these results shed light the importance of considering attributions to discrimination in the phenomenon of ostracism.</p></div> <div>Highlights and implications<p>§ Participants who attribute ostracism to discrimination display less psychological need satisfaction than participants who perceived less discrimination.</p><p>§ Sharing ostracism (i.e., as a co-experience) did not moderate identity responses as well as psychological need satisfaction § This study highlights the importance of considering perceived discrimination during ostracism even among non-stigmatized groups.</p></div>

  • You Are Not Alone! Sharing Ostracism Fosters Group Identification But Does Not Improve Well-Being

    Experiencing ostracism is a painful situation that can urge a desire to restore social bonds. However, few studies have investigated the conditions under which it leads to ingroup identification. In three studies using minimal groups ( N = 611), we have investigated the consequences of coexperiencing ostracism for group identification and well-being. In Study 1a and 1b ( N = 171; N = 211), the results showed that sharing a common experience of ostracism with an ingroup member increases ingroup identification but does not improve psychological needs during the ostracism experience. In Study 2 ( N = 230), we replicated our results on identification and showed that sharing ostracism fosters psychological closeness with the partner ostracized but does not moderate need recovery.

  • Do it for others! The role of family and national group social belongingness in engaging with COVID-19 preventive health behaviors

    COVID-19 is an unprecedented threat and an effective response requires a collective effort: engagement in preventive health behaviors, even from people at low risk. Previous research demonstrates that belongingness to social groups can promote prosocial, preventive health behaviors. The current research tests the effects of belongingness to two types of groups, intimate (family) and social category (nation), on intentions to comply with preventive health behaviors and reasons for these behaviors. We conducted three studies using French participants at low risk of grave effects from COVID-19 (total N = 875). In Study 1, across three time periods, belongingness was correlated with greater intentions to comply with preventive behaviors when these behaviors were not enforced by law. In Study 2, we experimentally manipulated threat to belongingness (vs. no threat). When belongingness was threatened, participants were less concerned with protecting vulnerable people. Closeness to family predicted preventive behavior intentions and both self-centered and prosocial reasons for these behaviors, regardless of condition. National identification buffered the negative effects of the threat to belongingness condition on preventive behavior intentions. In Study 3, we experimentally primed thoughts of belongingness to family vs. nation vs. control condition. We found greater intentions to engage in preventive behaviors and greater concern with protecting oneself and close relatives in the family condition. In summary, belongingness to one's family promotes preventive behavior intentions and the reasons given are to protect both oneself and others. Self-reported (but not primed) national identification can be related to prevention behavior intentions under certain conditions.

  • Halo It’s Meat! the Effect of the Vegetarian Label on Calorie Perception and Food Choices

    In the last few years, vegetarian products have become a widespread dietary option in food industry to the point that large retail chains such as McDonald’s has offered a vegetarian burger to their customers (e.g., the Grand Veggie). In the present research, two studies investigated the influence of a vegetarian label on calorie perception, frequency consumption and food choices. In the first study (N = 211) participants were randomly assigned to an experi-mental design 2 (burger type: Grand Veggie vs Big Mac). In the second study (N = 915), participants were either exposed to a similar burger labeled vegetarian or a meat-based. Both studies show that vegetarian products are perceived as being less caloric than their non-vegetarian equivalents. However, participants do not report more intention to eat more vegetarian products and do not lead to differences in menu composition.

    Ostracism and Social Dynamics: Causes, Consequences, and Interventions examines how exclusion shapes behavior, health, and group functioning across social, organizational, institutional, and societal contexts. This volume brings together a group of international scholars who investigate the conditions that give rise to interpersonal and intergroup exclusion, the psychological and biological processes that sustain its impact, and the contexts that both magnify and mitigate its effects. Chapters address a wide range of topic areas, including perceptions, modalities, antecedents, observer experiences, cognitive appraisals, psychological and behavioral responses, and neurological, physiological, and biological reactivity. This volume is unique in the level of theoretical integration across multiple research domains. The book highlights how exclusion unfolds in everyday interactions, the workplace, and larger social systems. Contributors analyze how contextual and structural features of organizations, cultural norms, and identity-based dynamics shape when ostracism and broader forms of exclusion occur and how individuals interpret such experiences. Several chapters examine moderating factors, including group membership, status, stigma, attributions, and developmental history. Others evaluate interventions designed to reduce bias, strengthen social connections, and improve social and organizational climates. This volume provides a cohesive framework for understanding exclusion as a dynamic social process. The book is intended for researchers, graduate students, advanced undergraduates, practitioners, and policymakers interested in theoretical, empirical, and practical insights into how exclusion operates and how its effects can be mitigated.
