Abstract

Previous findings on the association between theory of mind (ToM) and aggression in children are mixed. The social skills deficit view regarded ToM as a single-edged sword and proposed that a lack of ToM can lead to aggression, while the double-edged sword view proposed that children with advanced ToM can still show much aggression because children can also leverage ToM to harm others. To resolve the dispute between the two views, we conducted a meta-analysis combining cross-sectional and longitudinal findings from 53 studies including a total of 11579 children aged between 2 and 15 years. The overall negative correlation between ToM and aggression was small but significant (r = -.08). The negative correlation was robust, with the magnitude of the correlation being similar across physical vs. relational aggression, proactive vs. reactive aggression, cognitive vs. affective ToM, preschoolers vs. school-aged children, different aggression measurements, and different levels of societal individualism. Moreover, the negative correlation was found regardless of whether ToM and aggression were measured concurrently or at different time points, but the correlation was the largest when ToM was measured before aggression. Whether the aggression was bullying or not also moderated the association, with ToM only being negatively related to non-bullying aggression but not bullying. Together, these findings suggest that ToM is a single-edged sword to decrease general aggression and that aggression might also give rise to lower ToM capacity during development. This study systemically reviewed the existing mixed findings on the association between aggression and ToM during childhood using a meta-analysis. There was a negative correlation between ToM and aggression in children aged between 2 and 15 years. The negative correlation between aggression and ToM was stronger when ToM was measured first, followed by aggression, than vice versa. There was a negative correlation between non-bullying aggression and ToM, whereas there was no correlation between bullying and ToM. This article is protected by copyright. All rights reserved.
