The purposes of this study are 1) to make the list of achievement-related affective words in Japanese and 2) to clarify the relationships among causal attributions, affects, and learnig behavior in academic achievement situation. In Study I, a list of affective words was developed that based on 88 affective words (43 for success situation and 45 for failure situation) that were picked out using the free-answer method. In Study II, 105 out of 148 junior high school students who had taken the term examination in mathematics regarded their results as failure. They made causal attributions for their results, and rating affective reactions. Four weeks later, they reported about learnig behevior during the last week. Path analysis revealed that attribution to daily effort was positively related to feeling of regret, and ability attribution was positively related to perceived incompetence. Futhermore, learning behavior was positively related to feeling of regret, and was negatively related to perceived incompetence.
