Rhythmic synchrony among different individuals has often been observed in various religious rituals and it has been known to bring various psychological effects in human minds. This study investigated the effects of induced rhythmic synchrony with artificial agents in drumming on participants' visual illusions. The participants completed a task with three cartoon agents on a computer screen beating drums taking turns. We then investigated whether participants were tended to find more meaningful

We simultaneously compared an active condition, in which participants took the role as one of three agents to beat a drum, with a passive condition, in which they only observed three agents beating the drums. The results showed that pareidolia appeared strongly in participants where the drum rhythm was in sync, regardless of active and passive conditions.
