Behavioral and Biological Effects of Changes in Group Size and Membership.

Abstract

Groups performing complex tasks under operational conditions can be anticipated to undergo changes in size and membership. Accordingly, the present research project developed a paradigm for investigating effects of such membership turbulence with 2-person and 3-person groups residing in a programmed laboratory environment for 10 successive days. A range of mission parameters (e.g., performance tasks, motivation, group render composition, social interaction opportunities, etc.) was systematically explored during 10 studies that included 6 analyses of changes in group size and 4 analyses of changes in group membership. The resulting database provides the opportunity for inductive determinants of interrelationships among performance, behavioral, and endocrine effects that were assessed throughout each of the 10 group investigations.
