抄録

Identical decision problems in form may yield different decisions, depending on the subjective decision framing as a function of how the situation is described. This is called the framing effect. The Contingent Focus Model (Takemura, 1994) can theoretically explain why the framing effect emerges. The model hypothesizes that a risk attitude depends on how to focus on the possible outcome (focusing hypothesis), and how to focus on them is, in turn, contingent on situations of decision making (contingent focus hypothesis). To test this hypothesis, we conducted 2 experiments which manipulated the relative size of letters of outcomes to the other letters (n=180, respectively). The results indicated that the subjects were more risk-taking when possible outcomes were emphasizing than those when probabilities were emphasizing. The psychometric analysis using the model indicated that the size of effect of emphasizing conditions on decision making is not different from that of positive/negative frame conditions.
