Relations among theory of mind (ToM), the executive functions of working memory and cognitive inhibition, and frontal lesions were studied using path analysis in 43 school-aged children with traumatic brain injury. The relation between cognitive inhibition and ToM involved a single mediated path, such that cognitive inhibition predicted ToM through working memory. Frontal injury had a direct impact on working memory, which then separately determined ToM performance, the direct single paths between frontal injury and ToM being nonsignificant. The expression of ToM in school-age children with traumatic brain injury is not domain specific, but instead depends on the domain-general functions of working memory and cognitive inhibition.
