| Abstract: | A computer program is described that simulates the emergence of affiliation networks in preschool groups and examines theoretical issues raised by the model, including general issues of validation. The simulation implies that triadic interactions, although observed in preschool groups, are not essential in the formation of affiliative structures (contra F. Strayer and J. Noel, 1986) and that, in this age range, therefore, polyadic friendship groupings can be understood as sets of dyadic relationships. The model also demonstrates how group structures can be generated without reference to group-level processes (contrast W. Hartup, 1983). It also focuses attention on the role played by preference formation in social isolation, by demonstrating that inhibition of preferences can give rise to isolation. The model also suggests that social outcomes are best described by nonlinear functions (cf. W. Roberts; see record 1987-03785-001). (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
