This paper addresses the problem of relationships between the development of theory of mind (ToM) and executive function (EF). An overview of empirical findings leads to the conclusion that the complex picture of the relations between EF and ToM development may result from the intertwining of different types and levels of reciprocal influences. It is, on the one hand, the level of emergence-type vs. expressive-type influences, and, on the other hand, direct vs. indirect ones. Data from longitudinal and training studies suggest the asymmetry of reciprocal influences between EF and ToM, with the stronger impact of EF on ToM development, which supports the view that EF is a prerequisite of ToM development. A model is proposed that explains how different EF and ToM skills are involved in the specific types and levels of influences. The issue of disentangling in the analysis the different types of reciprocal impacts is also discussed.
The aim of the study was to examine the relationships of Level -1/Level -2 visual perspective -taking (VPT -1/VPT -2) with theory of mind (ToM) and executive function (EF). Seventy -six adults aged 18 to 48 years participated in the study. To compare the relationships of the two levels of perspective -taking with the aforementioned abilities, the same stimuli were used in both Level -1 and Level -2 trials of the VPT task. ToM abilities were evaluated with the Strange Story task, and EF using the TMT and WCST tests. It was found that controlling for age -related differences, VPT -1 was not associated with either ToM or such components of EF as executive control and set -shifting. VPT -2 was positively related to ToM, but it was not related to EF. The relationship between VPT -2 and ToM was specific, not mediated by domain -general processing capabilities. The obtained results provide further evidence to support the view that distinct mechanisms underlie Level -1 and Level -2 perspective -taking.
