【 摘 要 】

Background: Theory of mind and executive function deficits have been implicated in a wide range of neurological conditions, including traumatic brain injury (TBI) and autism spectrum disorder (ASD). Uncertainty remains about the degree of overlap of these functions, as well as the mechanisms that may be involved in specific disorders. The role of other processes, such as anxiety, has also not been considered. Aims: To investigate the role of anxiety in individuals with ASD and TBI in their executive function and theory of mind abilities. Methods: A prospective between groups design was used to compare ASD and TBI groups. Relaxation training was implemented and individuals were compared pre- and post- relaxation on measures of executive function and theory of mind. Results: Pre-relaxation scores indicated the ASD group had significantly higher anxiety than the TBI group, but with relaxation improving anxiety in both groups. Significant interactions of executive function, theory of mind and group were found, with the ASD group scoring higher after relaxation. A significant correlation was also found between executive function and theory of mind, but only in the ASD group. Conclusions: The present results suggest anxiety may play a significant role in the executive function and theory of mind deficits observed in ASD. TBI may involve different mechanisms which impact on functioning. Applications: The findings raise important implications for intervention and the potential to develop executive function and theory of mind skills in ASD.
