This study investigated the impact of shared art experiences on prosocial behaviour and social connectedness in parents of young children. A field experiment compared parents attending a concert with their child to those attending a playtime session and those who did not attend the experiment. While the single art experience of the concert did not significantly alter social connectedness with similar or dissimilar others, it did increase connectedness to humanity compared to non-attendees, with a similar trend for the playtime group. Additionally, parents who did not attend the experiment felt more connected to their child than parents who attended the playtime. Furthermore, the study did not find an immediate increase in prosocial behaviour after an art experience, contrary to expectations. However, a positive correlation between habitual art engagement and trait prosociality suggests that sustained engagement with art may foster prosocial trait tendencies over time. The study was limited by its underpowered sample and potential demographic biases. The findings suggest that while a single art event may only contribute to the universal sense of social connectedness in parents, consistent engagement with art could contribute to the development of prosocial traits.
