Three studies were conducted to examine the characteristics of achievement -related affects in Japan. In Study I, 123 achievement-related affective words (57 for success situations and 66 for failure situations) were picked out using the free-answer method. In Study II, the ratings concerning the list of affective words obtained in Study I were factor analyzed. The results revealed 5 affects for success and 7 affects for failure. In Study III, 544 university students were randomly arranged in one of the 16 experimental conditions (8 attributions 2 outcomes) to examine the linkage between attributions and affects. Then an attribution and an outcome information were given within a brief story format, and subjects rated the intensity of the affective reactions using the word lists made in Stydy II. The results showed that 7 affects linked with specific attributions, and these results matching closely with Weiner et al (1978, 1979) and with Nasu (1990).
