Developing Theory of Mind in social domains: A cross‐sequential study of Chinese rural preschoolers

Abstract Theory of Mind (ToM), the ability to understand others' thoughts and emotions, is crucial for social interaction. However, few longitudinal studies have explored ToM development within different social domains, particularly among rural populations. To address this gap, we conducted a study with 113 preschoolers aged 3–5 years from rural China. We assessed ToM development in different social domains using false belief tasks at three different time points with semester intervals, and we evaluated their performance on the Peabody Picture Vocabulary Test and inhibitory control (IC). Results showed that ToM development trajectories differ across domains, with moral and social‐conventional domains developing earlier than the personal domain. Additionally, while general cognitive skills such as language and IC are associated with ToM development across these domains, they do not significantly predict it. This study enhances our understanding of ToM development by emphasizing the importance of including rural samples in developmental research.
