The effects of age and competence type on emotional reactions were demonstrated in this study. Participants: (362 junior high-school students, 658 senior high-school students, 407 undergraduates, and 1027 adults) were asked to rate the Assumed-competence Scale, second version (ACS-2) and Rosenberg's Self-esteem Scale, which were prepared to classify the participants into four competence types: Omnipotent, Assumed, Self-respective, and Atrophy. They also rated their perceived emotional reactions toward negative personal and social events, and the responses were compared among age groups and competence types. Remarkable results showed that the Assumed and the Atrophy types were prominent in junior and senior high-school students. They tend to get angry toward negative personal events, and they also tend not to respond emotionally toward social events. Another result was that people in the Assumed and Omnipotent types were likely to get angry toward both personal and social events, and they were also less responsive toward social events.
