Conformity effects in memory as a function of group size,dissenters and uncertainty

In two experimental studies we investigated how false memory reports provided by anonymous group members affect individuals' recognition. Participants were presented with a series of salient and non‐salient objects and recognition memory was subsequently assessed for presented and non‐presented stimuli. In this recognition test, participants were confronted with (in)correct responses from bogus group members. The findings indicate that the bogus answers influenced memory reports only in the absence of a clear recollection and if the stimulus was not judged to be particularly memorable. Moreover, we found no evidence that motivational influences affected participants' judgements. However, the influence of the bogus group decreased with the presence of dissenters who broke the unanimity of the group, and it increased with higher uncertainty.

Motivation as a function of success frequency

Motivation and Emotion - It is well-established that intermediate challenge is optimally motivating. We tested whether this can be quantified into an inverted-U relationship between motivation and...     

Conformity as a function of task generalization and relative competence

Subject correctness and group agreement were varied for college subjects engaged in a light discrimination task. On another task, employing multiple-choice questions about Canada, the dependent variable of conformity was assessed to examine generalization of relative competence formed on the light discrimination task. It was seen that (1) relative competence was seen to mediate conformity for a specific task (Canadian Knowledge Inventory), but did not generalize across tasks (i.e. from the light discrimination task to the Canadian Knowledge Inventory); (2) with respect to the Canadian Knowledge Inventory, subjects who perceived themselves as more competent than the group did not conform as much as those who either perceived themselves as less competent than or as competent as the group; (3) the experimental manipulations did not affect conformity, further supporting the findings that perceived competence does not generalize across classes of tasks; (4) females conformed more than males: and (5) nonsuspicious subjects conformed more than suspicious subjects.     

Reactions to group success and failure as a function of identification level: a test of the goal-transformation hypothesis in social dilemmas

This study examined the combined effects of identification level, social value orientation, and feedback on contributions in a public goods dilemma. Previous research has shown that strengthening group identity promotes cooperation. One explanation for this finding is that a strong group identity transforms people's motives from the personal to the collective level (the goal transformation hypothesis). Evidence for this hypothesis can be found in studies showing that a strong sense of group identity influences proselfs, relative to prosocials, to make larger contributions. In this experiment, we demonstrated that these findings are restricted to situations in which no feedback about a group's performance is provided. When performance feedback is provided, a strong group identity cancels the effects of individual differences in social value orientations. In particular, when a group fails, contributions increase if group identity is salient, but decrease if personal identity is salient, regardless of a person's social value orientation. But when a group succeeds, no differences between group and personal identity are found. These results are discussed in terms of the goal transformation hypothesis.     

The effectiveness of men and women in problem-solving groups as a function of group gender composition

Previous research suggests that the fewer women in a group, the less likely their ideas will be considered. The present study was designed to test the effect of gender composition on women's influence. Thirty groups were asked to solve two problems, first as individuals, then as groups. Composition and gender of the subject receiving a helpful clue were varied. Subjects rated the second task and members of the group, and a Bales Interaction Analysis was conducted. Results indicated that men were more influential than women only when in the minority, that women had smaller proportions of leadership acts than men, and that some stereotyped attitudes existed. Results were discussed in terms of previous findings, and suggestions for future research were made.     

The group as a resource: reducing biased attributions for group success and failure via group affirmation

Self-affirmation theory proposes that people can respond to threats to the self by affirming alternative sources of self-integrity, resulting in greater openness to self-threatening information. The present research examines this at a group level by investigating whether a group affirmation (affirming an important group value) increases acceptance of threatening group information among sports teams and fans. In Study 1, athletes exhibited a group-serving attributional bias, which was eliminated by the group affirmation. In Study 2, the most highly identified fans exhibited the most bias in terms of their attributions, and this bias was eliminated by the group affirmation. These studies suggest that groups can serve as resources from which people can draw in response to threatening group events.     

The self-attribution of emotion as a function of success and failure1

When an act is interpreted as emotional, the responding individual generally is considered less responsible than if the act were interpreted as deliberate. This leads to the hypothesis that the self-attribution of emotion will more likely occur when behavior has undesirable rather than desirable consequences. Three experiments were conducted to explore this hypothesis. In these experiments, the self-attribution of emotion was assessed indirectly by having the subjects judge potentially arousing stimuli (e.g., nudes and corpses) after these stimuli had been associated with either failure or success on a problem-solving task. As predicted, the nudes were judged more attractive and the corpses more disturbing when they were associated with failure. This tendency was most apparent among subjects who perceived the task to be a valid indication of intellectual ability.     

Interindividual‐intergroup discontinuity as a joint function of acting as a group and interacting with a group

An experiment assessed the prisoner's dilemma game (PDG) choices of a set of three persons who interacted with another supposed set of three persons. There were four conditions: (1) group‐on‐group (both three‐person sets constrained by a majority vote), (2) group‐on‐one (only own three‐person set constrained by a majority vote), (3) one‐on‐group (only other three‐person set constrained by a majority vote), (4) one‐on‐one (neither three‐person set constrained by a majority vote). The four conditions were compared with three orthogonal contrasts. Consistent with the assumption that interindividual interactions are less competitive than interactions involving groups, the first contrast indicated that there were fewer competitive choices in the one‐on‐one condition than in the other three conditions pooled. Consistent with the assumption that competitiveness can flow either from acting as a group or interacting with a group, the second contrast found no significant difference between the group‐on‐one and one‐on‐group conditions. Finally, consistent with the assumption that the interindividual‐intergroup discontinuity effect is a joint function of acting as a group and interacting with a group, the third contrast revealed that there were more competitive choices in the group‐on‐group condition than in the one‐on‐group and group‐on‐one conditions pooled.

Conformity as a function of the consistency of positive self-evaluation with being liked and being right

Insko, Sedlak, and Lipsitz (European Journal of Social Psychology, 1982, 13, 143–167) have presented evidence that agreement effects in p?o?x triads, or semicycles, are at least partially a function of the consistency of positive self-evaluation with being liked and the consistency of positive self-evaluation with being right. Consistent with the Insko et al. balance interpretation of agreement effects, results indicated that conformity in an Asch-type experiment is a joint function of the concern with being liked and the concern with being right. The judgment stimuli were sets of three colors, and the subjects' task was to indicate whether the middle color was more like the color on the left or the color on the right. In the main experiment, subjects conformed more with public than with private responding, and also when they were led to believe that the relationships among the colors were objectively determined rather than undetermined. The first of these two results (in conjunction with the lack of an interaction and the presence of a difference between the public condition and a private camera control condition) was taken as evidence for the concern with being liked. The second finding of a difference between the determined and undetermined conditions was taken as evidence both for the concern with being right and also as indicating that conformity can occur with objective stimuli. Although concepts similar to the concerns with being right and liked have been widely discussed, a review of the literature indicated that the previously presented evidence is not totally convincing.
