Both naturalistic observation and questionnaire methods are used to investigate the helping behavior by college students. A total of 243 undergraduates were observed on and outside of the campus whether they helped a female physically handicapped adult in distress. Then 86 were asked to fill out questionnaires to explain their cognition and affections toward this matter. The result showed that there were four out of five who helped the confederate voluntarily. It also indicated the consistency between actual and verbal aiding, cognition and affections, cognition and action, and affections and action. The ratio of consistency among cognition, affections, and action is 82%, however, it revealed the stability and integration of moral character. The factors of sex, religion, place, experience in contacting with the handicap, and studies on special education courses showed no effect on helping behavior. But the subjects are more willing to help the familiars than the strangers. The result also presented that college students are used to extending help with fixed pattern. And the attitude of most of those who did not offer aiding has become more positive toward the physical handicaps through introspection after this experiment. Finally, some suggestions about moral education are postulated.
