To explore the relation among judgment of responsibility, emotional experience, group relationship and helping behavior of college students, a questionnaire survey has been taken. The result shows that judgment of responsibility, emotional experience and group relationship are correlated with helping behaviors, which indicates that the theoretical assumption “action attribution→aesthesia controlling→judgment of responsibility→emotional experience→offering assist” proposed by Winner is universal and reliable. The attributions to others’ responsibility, emotional experience and group relationship have a marked effect on college students’ will of help-offering. The relationship with internal and external groups would influence the helping behavior of college students. They would be more likely to offer assistance to the group members.
