The relative effectiveness of alternative reward structures in strengthening individual task performance was investigated by operationalizing six reward structure treatments--each of which combined one of two levels of differential group rewarding with one of three levels of differential rewarding within groups.

Several factors thought to influence the representativeness of behavioral assessment data were examined in an analogue study employing a multifactorial design. Systematic and unsystematic methods of observing group behavior were investigated using 18 male and 18 female observers. Additionally, valence properties of the observed behaviors were…

This experiment was designed to test the motivation to perform a task for males and females in mixed and same-sex groups. Individuals in homogeneous groups (four males or four females) or heterogeneous groups (two males and two females) clapped their hands alone, in pairs and in foursomes. People exerted more effort alone than in groups,…

This study suggests female and male verbal behavior should be viewed separately when analysing task-importance. Ego-involvement works with task importance to create atmospheres of maximum involvement. Characteristics of communication and group pressure for uniformity are identified. (MFD)

This study assesses if initial attitudes and beliefs of a behaviorally homogeneous group (1228 females and 868 males) can be utilized as indicators of future smoking behavior. Results suggest attitudes and beliefs of initial never smokers may serve as indicators of future behavior. (Author)

In comparing educated, adjusted male homosexuals to educated, adjusted heterosexuals, no differences were found between the groups using the traditional index of homosexuality on the Rorschach. Results suggest the traditional index is not valid and should not be used in clinical settings as a measure to assess homosexuality. (Author)

Two all male groups, two all female groups, and two mixed groups were studied over five 90-minute sessions. Interaction data was gathered by two observers who recorded each time a member spoke and to whom he/she spoke. Group meetings were…
