Hidden Profiles and Concealed Information: Strategic Information Sharing and Use in Group Decision Making

Abstract: Two experiments investigated the differential impact of cooperation and competition on strategic information sharing and use in a three-person group decision-making task. Information was distributed in order to create a hidden profile so that disconfirmation of group members' initial preferences was required to solve the task. Experiment 1 revealed that competition, compared to cooperation, led group members to withhold unshared information, a difference that was not significant for shared information. In comp… Show more

L'impact conjoint des préférences initiales et du partage d'informations est aujourd'hui reconnu dans des élaborations théoriques (Tindale, & Kameda, 2000 ;Stasser & Dietz-Uhler, 2001 ;Tindale, Meisenhelder, Dykema-Engblade, & Hogg, 2001) et travaux empiriques (Augustinova, 2008 ;Toma & Butera, 2009). …”
