Outline of Final Research Achievements

By carrying out a social decision making of judging good or bad based on conjecturing the intention of others to the elderly people, we attempt to clarify the characters of the judgement skills of good or bad, to verify the judgement skills of good or bad of the neurocognitive function due to aging using the functional MRI, to give a psychoeducation in order to improve the ability to give correct judgements to others. The results of the behavioral test shows compared to the young people the elderly tend to give a better judgement toward a person and also tend to make a decision based on the behavior rather than on the characteristics of the person when judging others. In addition, the result suggests there are possibilities that the self-efficacy of a person has an influence on the weakness toward fraud.
