Abstract: This study focused on the cognitive and affective processes that were thought to produce shifts toward greater risk and caution in decision-making following group discussion.In order to test specific hypotheses Jerlved from these processes an SEU model for individual choice behavior was applied to the Choice Dilemmas task.Three experiments demonstrated that Individ uals decisions regarding risk (i.e., minimum probability of success which an individual would accept, p) could be accounted for by a rational decision rule which is maximization of subjective expected utility (SEU).When minimum acceptable probabilities were predicted from the relative utilities of the possible outcomes (i.e., utilities ratio, fi) these estimated values were quite close to the actual risk level chosen, p.The function p = p described the obtained relation ship fairly well, before as well as after group discussion and decision.Two hypotheses that accounted for the shifts in terms of cognitive processes were tested.The first hypothesis, informational influence, suggests that new information raised during the group dis cussion influences the person's view of the situation (i.e., his assessment of the utilities of the potential outcomes) and this in Summary of the Purpose of the Study 55 CHAPTER III.METHOD 58 Overview of the General Design 58 Material ,n
