Abstract
The relationships amongst within-group communication, group identification, and perception of shared cognition were examined across the time. Data was collected three times from 269 participants during a simulated society game named SIMINSOC (Simulated International Society; Hirose, 1997). Results of structural equation modeling indicated that communication within the group strengthened group identification, which further facilitated the perception of shared cognition. Further, group identification was found to facilitate communication during subsequent simulation sessions. These findings suggest a process of mutually reinforcing, reciprocal relationship between communication and group identification, and the resultant formation of strong perception of shared cognition. We discussed the impact of this reciprocation process within a group setting, which involve cooperative behavior and group polarization in decision making.
