Abstract

Two studies were conducted to test Shafir's(1993) response compatibility hypothesis in decision-making. These studies examined whether participants choose as well as reject the enriched option more frequently than the impoverished option. We constnacred five new decision-making problems in addition to Shafir's(1993) five problems in Study 1. Only one out of 10 problems produced the results consistent with the prediction of the response compatibility hypothesis. In Study 2, decision problems were modified to control for selettive attention each option's features, but the same pattern of results was obtained in this study. A new hypahesis wac presented to discuss our results.
