Robust research has shown that correlated rhythmic movements increase a sense of affiliation between young children, and my recent MSc work shows that visually-induced synchrony can promote not just prosocial feelings but also an enhanced sense of similarity for a ‘virtual’ child. More specifically, my work set to study how different interpersonal synchrony experimental conditions (e.g., auditory, visual, virtual reality and real person experience) can induce and enhance children's social perception of others within a peer group. I will focus on two age groups of children, across the typical spectrum of social intelligence: 1) 3- to 5- years of age (the beginning of formal education), and 2) 9- to 11-years of age (the end of primary school, beginning of adolescence).
