Abstract

This study aims to elucidate attitude formation in group situation. We conducted a psychological experiment which was controlled self profit, procedural justice and group pressure. As a result, following findings were obtained. 1) Binary logistic regression analysis revealed that self-profit and group pressure were important factors of attitude formation in group situation. 2) Approximately, 10% of subjects who were under group pressure were influenced by public conformity. 3) Adding to subjects who were influenced by private conformity, about 40% of subjects were influenced by group pressure. 4) It was suggested that conformity, private interests, and procedural fairness were important factors that differentiate between private acceptance and compliance. 5) When people behave in conformity, if low private interests, low procedural fairness, and high group pressure are perceived, they behave in compliance. However, if high private interests, high procedural fairness, and sort of high group pressure are perceived, they behave in private acceptance.
