The present study investigated how type of interaction between groups affects intergroup hostility and how this intergroup hostility may be reduced. In the first phase of the study groups were led to believe that they were either competing, cooperating, or having no interaction with a second group. The results indicated that competition led to the…

Prior theoretical formulations have suggested that client exposure to levels of personal risk and responsibility most conducive to optimal group development can be regulated with group structure. Analysis of variance results indicated the highest frequency of therapeutically relevant behaviors occurred in the high-structure and high-risk-taking…

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,…

Explores the reactions of single persons and small groups-each in a room they had territorialized- and to compare these against the reactions of singles and small groups who were in a comparable room which they had not territorialized. (Author)

Relationships among peer social interaction rate, classroom activity, and teaching style were investigated to determine whether teaching style could be defined in terms of differential student interaction rates across various classroom activities. Peer interaction rates were determined in three primary level classrooms representing various…

The degree of acquaintance among group members (friends or strangers) and the opportunity for group members to observe each other's actions (anonymous or non-anonymous) were manipulated in a 2 x 2 factorial design, to determine the amount of aversive stimulation that would be administered to a target person. When group members could not observe…

The role of feedback in T-groups was studied. Results indicate that feedback increases as T-groups progress, feedback is more emotional and non-evaluative than cognitive in nature, positive and direct feedback to the leaders increases as the group develops, and specific feedback between members increases as groups progress.

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)

This study, employing inclusion, control, and affection as independent variables, tests empirically Schutz' (1958) three-dimensional theory of group process, using a Prisoner's Dilemma experimental analogue situation with dyads. (Author)

This paper reports a study of the characteristics of the social interaction of single sex and mixed groups. 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…

An experiment was performed in which 155 undergraduate student subjects were provided with information about a stimulus person whose behavioral consistency varied on several issues. The study assumed that if the individual's behavior on the relevant topic was consistent, then behavior on the other issues should have no impact on persuasiveness,…
