| Outline of Final Research Achievements |
This study examined the relationship between collective intelligence and synchrony among group members. The results of multiple (dyadic or triadic) interaction experiments showed that the affective contrast between interactants suppressed synchrony (1) and synchrony improved the accuracy of judgment about affective states of an interaction partner (2). On the other hand, especially in a brainstorming task context, synchrony among group members increased the quantity of ideas (3), whereas the quality (i.e., creativity) of ideas was decreased due to a high-degree of synchrony (4). Perceived rapport was also decreased by synchrony (5). Previous studies have demonstrated that synchrony is a general facilitator of smooth communication; however, this study suggests that synchrony can have a detrimental impact on group task performance in an idea generation context.
