Reviews group behavioral issues from past space missions and simulations such as the Skylab Medical Experiments Altitude Test, Skylab missions, and Shuttle Spacelab I mission. Makes recommendations for future flights concerning commandership, crew selection, and ground-crew communications. Pre- and in-flight behavioral countermeasures are…

The purposes of this paper are to note specific weaknesses characterizing small group research and to propose suggestions for their solution. Adapted from a speech given at the Second National Conference about the Teaching of Group: Theory and Practice, Temple University, Philadelphia, February 1976. (Author)

In the absence of information to the contrary, an individual tends to assume that members of an out group have values which differ from his own. The effect is even more marked for highly prejudiced persons. In the present paper two experiments are reported which extend the belief similarity hypothesis. (Author)

Presents a theoretical model of group development based on five stages of development, each with a central issue. They are (1) orientation stage (dependence vs independence); (2) conflict stage (control vs adaptation); (3) integration stage (implicit vs explicit social structure); (4) achievement stage (intellectualizing vs implementation); and…

Examined the relationship between interpersonal relationships in groups and the attitudinal resolutions of the first six developmental crises of Erikson's theory of personality. Findings indicated that Erikson's attitudinal variables significantly differentiate group roles, and can assign subjects to group role categories with reasonable success.…

Examined whether compatible groups facilitate learning more than incompatible groups. Used peer groups to facilitate learning in college courses. Computed compatibility scores for pairs and four-person groups working together. Used examinations to measure peer group procedure effectiveness. Results did not indicate a positive relationship between…

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, 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)
