Groups, group members and individual decision processes: the effects of decision strategy, social interaction style and reception of decision-threatening information on post-decision processes.
In two experiments, one conducted at an individual level and one at a group level, it was investigated how decision strategies and the reception of decision-threatening information affect the degree of post-decision consolidation for both individual and group decision-makers. In Experiment 1, roughly half the 55 participants made decisions in three-person groups and the other half individually. The type of decision strategies subjects employed (compensatory, non-compensatory, other) was assessed by questionnaire. In two post-decision sessions, consolidation was assessed using a memory task, either decision-supporting or decision-threatening information being provided at the start of the last post-decision session. In Experiment 2, the same design and procedure were used at a group level. In both experiments, the groups (and the single group members) were analyzed with the SYMLOG instrument. The results indicated that individual decision-makers consolidated their own decisions more than members of decision-making groups. There was also greater post-decision consolidation with the use of non-compensatory decision strategies as well as with reception of decision-threatening information, this latter result being seen as providing an explanation for the greater consolidation that individual decision-makers showed. Furthermore, single task-oriented group members and groups with a task-oriented leader consolidated the decision made by their group.
