Abstract

Existing models of group behavior, in a variety of fields, leavemany open challenges. In particular, existing models often focusonly on a specific phenomenon (e.g. flocking, pedestrianmovement), and thus must be switched depending on the goals of thesimulation. In contrast, we investigate a general cognitive modelof simulating group behaviors, based on Festinger's SocialComparison Theory (SCT), a prominent social psychology theory. Inprevious work, we have shown SCT covers a variety of pedestrianmovement phenomena. In this paper we present evidence for SCT'sgenerality by describing the use of the SCT model (using the Soarcognitive architecture) in generation of imitational behavior inloosely-coupled groups. Since the imitational behavior does nothave clear standards of evaluation, we propose a method for such evaluation. Based onexperiments with human subjects, we show that SCT generates behaviormore in-tune with human crowd behavior.
