Ten Japanese experimenters conducted an experiment in person perecption with a total of 80 Japanese subjects at Keio University. For half their Ss, Es were led to expect Ss to rate photos as being of successful people. For the remaining half, .Es were led to expect Ss to rate photos as being of unsuccessful people. Unlike the results of two earlier Japanese experiments, the present study found no tendency for a reversal of the effects of E expectancy. There was, however, as in the earlier studies, a change in the magnitude of E expectancy effect in going from the first half to the last half of the experiment. Just as in earlier American studies, Es obtaining greater positive effects of their hypotheses were judged as both more relaxed and as more expressive. The behavior of these more biasing Es, however, was seen by Japanese observers in a somewhat negative and unprofessional way while American observers had seen these more biasing Es of the earlier American studies in a more positive light and as behaving more professionally.
