A laboratory experiment examined the effect of confederate status and task structure on group members' use of the confederate's problem solving strategies (private/indirect influence) and divergent thinking. Twenty-eight three-member, all-female groups, with an experimental confederate acting as one of the group members, solved an open-structured or closed-structured logic problem. The confederate, randomly assigned to be higher-, lower-, or of undesignated-status, presented a scripted but unique solution to the group while solving the task. Lower-status confederates and openstructured tasks, relative to higher-status confederates and closed-structured tasks, had more private, indirect influence on group members and caused more divergent thinking. We discuss the implications of these findings for group dynamics and social influence literatures. Copyright # 2009 John Wiley & Sons, Ltd.The study of social influence in groups has a long and rich history (Cartwright & Zander, 1968;Deutsch & Gerard, 1955;Lewin, 1948;Moscovici & Nemeth, 1974;Raven & French, 1958). Of particular interest have been the means by which leaders, experts, and other relatively high-status group members influence the perceptions, opinions, and decisions within groups. As a top-down process, the pattern of influence is clear: Powerful and prestigious group members tend to have strong, direct, and immediate effects on other members of the group, often inducing high levels of compliance (Deutsch & Gerard, 1955;Raven, 1965).Although much is known about social influence from powerful group members, comparatively less is understood about their lower-status counterparts and the means through which they might influence their fellow group members (cf. Moscovici, Mucchi-Faina, & Maass, 1994). In any given social situation, there are bound to be status differentials among the various actors (Berger, Ridgeway, Fisek, & Norman, 1998;Ridgeway, 1984;Sidanius & Pratto, 1999). Consider a corporate office, regional hospital, or a high school classroom. In each of these settings, there are higher-status people (e.g., CEOs, doctors, teachers) who manage the situation and lower-status people (e.g., executive assistants, patients, students) who actively participate in, but typically do not command authority over, the organizational setting. In such settings, must influence flow only from the top-down, or are there times when the suggestions by lower-status individuals European Journal of Social Psychology Eur. J. Soc. Psychol. 40, 1184-1199 (2010 might hold sway? In this study, we investigate two factors, member status and task structure, that suggest circumstances under which influence may proceed from the bottom up.
STATUS AND INFLUENCEAlmost by definition, the social position of a relatively high-status group member affords influence over others (Raven & French, 1958) and, in turn, elicits a high degree of normative influence within groups (Kaplan & Martin, 1999). The assumed credibility and competence of those who occupy relatively high-status position...
