Theory of mind (ToM), the ability to understand other agents have different beliefs, desires and knowledge to oneself, has been extensively researched. Theory of mind tasks involve participants dealing with interference between their self-perspective and another agents perspective, and this interference has been related to executive function, particularly inhibitory control. The current study assessed whether there are individual differences in self/other interference, and whether these effects are due to individual differences in executive function. 142 participants completed two theory of mind tasks (the Director Task and a level one visual perspective-taking task), which both involve self-other interference, and a battery of inhibitory control tasks. The relationships between the tasks were examined using path analysis. Results showed that the self/other interference effects of the two ToM tasks were dissociable, with individual differences in performance on the ToM tasks being unrelated and performance in each predicted by different inhibitory control tasks. We suggest that self/other differences are part of the nature of theory of mind tasks, but self/other interference is not a unitary construct. Instead, self/other differences result in interference effects in a variety of ways and at different stages of processing, and these effects may not be a major limiting step for adults’ performance on typical ToM tasks. Further work is needed to assess other factors that may limit adults’ ToM performance and hence explain individual differences in social ability.
