Resumo: Based on the attributional reformulation of social comparison theory (Goethals &Darley, 1977) and on previous studies (e.g., Lopes, Vala, &Garcia-Marques, 2007), the present research extends our understanding of the role of group consensus and heterogeneity on attribution of validity to group opinions and decisions. One experimental study tested the hypothesis that the effect of group heterogeneity on the validity attributed to group decisions is mediated by the perceived group participation when group consensus is high, but not when group consensus is low. The results support this mediated moderation hypothesis and are discussed in the light of the epis-temic value of heterogeneity and consensus information in group decisions and opinions.

Une étude expérimentale teste l’hypothèse selon laquelle lorsque le consensus du groupe est fort, mais non quand il est faible, l’effet de l’hétérogénéité du groupe sur la validité attribuée à ses décisions est médiatisé par la perception qu’il y a eu une bonne participation des membres du groupe. Les résultats confirment cette hypothèse de modération médiatisée et sont discutés à la lumière de la valeur épistémique de l’information sur l’hétérogénéité et sur le consensus dans les décisions et les opinions de groupe.Presses univ. de GrenobleRepositório da Universidade de LisboaLopes, DinizVala, JorgeOberlé, DomininqueDrozda-Senkowska, Ewa2014-11-10T10:36:49Z20142014-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10451/12391porLopes, D., Vala, J., Oberlé, Dominiqu, Drozda-Senkowska, Ewa (2014).
