This study is about generalization of expected value on similar stimulus. From precedent study about perception, it is known that generalization curve of loss context is wider than gain context. In this study, we were interested in the effect of reward context on transfer of expected value in similar stimulus which is easy to be discriminated to original. The experiment was divided to learning phase and decision phase. In learning phase, participants learned association between orientation and rewards, and in decision phase, they valued willingness to bet on stimulus those are similar to learned stimulus. As a results, there was a transfer of expected value on similar stimulus. Also, the strength of willingness to bet was depend on the degree of similarity. There was no significant difference between gain and loss context. However, when modifying condition to be biased to gain, the difference of strength of willing to gamble did not shown. It seems that minor loss cannot cause loss aversion behavior in gain context. Also, even if the gain is much bigger than loss, there is no significant much stronger tendency of gain seeking.
