Risky shift as a function of group members' value of risk and need for approval.

Assigned 88 female undergraduates to dyads homogeneously composed with regard to their valuation of risk acceptance (low or high) as well as their need for approval (low or high). The dyads discussed each of a set of hypothetical decision situations involving risk taking and, at the end of each discussion, indicated the risk levels acceptable for them. High-value dyads shifted significantly more toward risk, relative to their prior decisions. Results demonstrate that risk as a value plays a causal role in the group risky-shift effect. The parsimony of recent formulations of the value theory of risky shift is discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
