STRUCTURAL FACTORS IN GROUP BEHAVIOR, by R. L. Hamblin Computer programs were developed for analysis of psychophysical and social psychological data gathered with such measurement procedures as magnitude estimation one program was designed for multiple correlation-multiple regression analysis of the relationship between one dependent variable and up to 50 independent variables. Socio-psychological experiments were made with college students from Brigham Young Univ., Provo, Utah, and then replications were made at the Naval Medical Research Inst., Bethesda, Md. Variables in the experiments such as status, utility, reinforcement, confidence, and moral attitude had a direct bearing on aggressive patterns in groups full of conflict and also on facilitative patterns. All the investigations were designed after the psychophysical model and utilized psychophysical methods. INDIVIDUAL NEEDS IN THE GROUP SITUATION, by R. deCharms. A study was made on schedules of leader contingency, perception, and productivity. With respect to achievement motivation and extrinsic versus intrinsic incentives, a preliminary study indicated that reversing the extrinsic incentive produces a large effect, that the effect is more evident in some subjects than others, and that the effect is related to the sex of the subject and to his level of fear of failure.
