The time window for sense of agency in school-age children is different from that in young adults

Is there a difference in sense of agency between children and adults? This study investigated the difference in the time window of sense of agency between school-age children (N = 94, aged 6–12 years) and young adults (N = 30, aged 21–23 years) by using an agency attribution task and international standardized manual dexterity test. The results showed that the time window for sense of agency was significantly shorter in children compared to young adults. In addition, there was a significant correlation between the time window for sense of agency and manual dexterity only in children. The present results suggested that sensory-motor function greatly contributes to sense of agency in school-age children.
