How Do Logical Inference Rules Help Construct Social Mental Models?

Starting from recent approaches in mental model research, it is argued that (1) logical inference rules are used in order to construct mental cliques from learned sentiment relations, and (2) social context cues (operationalized as primes) play a crucial role in activating such rules. Transitivity and antitransitivity are taken as examples, and are shown as core constituents of such models. In a first experiment, priming was achieved by announcing the sorting of fictitious persons in either two or three cliques. Thirty-one subjects studied eight sets of sentiment relations among these persons that either did or did not satisfy their primed clique expectations. They showed longer study times and more requests for additional information in the case of inconsistent fits between prime and set. Their sorting solutions also showed clear priming effects. A second experiment (n = 30) showed that when undergoing a recognition test after seeing the relation sets, subjects tended to confuse model-consistent distractors with information they had actually seen. In a third experiment (n = 30) the results from Experiment 1 were replicated using more realistic learning materials.

The Social Influence of Confidence in Group Decision Making

This study investigates the relation between an individual's self-reported confidence and his or her influence within a freely interacting group. Each participant chose responses and provided confidence assessments for choice items of a variety of task types, first as an individual and a second time as a member of a pentad, a member of a dyad, or an individual. The influence of a particular faction within a group was greater if its members were more confident. A participant's response accuracy was related to both greater confidence and greater influence to the extent that the task fell on the intellective end of the intellective-judgmental continuum of task types. As a result, the extent to which group members' confidence predicted their influence was also greatest on intellective rather than judgmental tasks. Results further illustrate that adding group members to work on a problem may increase overconfidence on judgmental tasks but decrease overconfidence on intellective tasks.
