| Prosocial behavior refers to all the behaviors having positive impact on others or social. Sociability and Reciprocity are the most significant characteristic of prosocial behavior, while features of sociability include social-interaction and social-desirability and features of reciprocity include altruism and egoism. Prosocial behavior can benefit others and even the whole population, and develop the harmonious relationship between both contacts. Essentially, prosocial behavior reflects the relationship between self and others, group or social, and positively influences the subsistence and adaptation of human beings and social development. For the researches of prosocial behavior, an essential issue of psychology, traditional study methods mainly include rating, observation and questionnaire. There are more or less limitations in these three methods, which greatly reduce the validity of measurement. When we apply these distorted data to relevant researches of prosocial behavior, inaccuracy of researches will be resulted, causing misunderstanding of prosocial behavior.In order to improve the measurement validity of prosocial behavior, this research attempted to use undergraduates as subjects and devise a measurement in computer-simulation situation to assess the behavior of donation exclusively. The higher validity of measurement in computer-simulation situation has been proved through criterion as peer rating, so that the donation level of subjects can be measured accurately and efficiently.Subsequently, we made use of this measurement to evaluate the donation of undergraduates in detail, and results showed that: 1. Donation level of undergraduates were high; however, great individual differences also existed; 2. when facing acquaintance in difficulties, the most donations of undergraduates were stimulated; 3. Female undergraduates donated more than males in general.On this basis, we made a further research on the relationship between donation and personality, and results showed that: 1. Agreeableness and conscientiousness in Big Five positively correlated with donation, while openness negatively correlated with donation; 2. there were gender difference in cognitive processing of undergraduates. To male undergraduates, conscientiousness is the prime personality factor influencing donation; as agreeableness to females. |
