The link between Theory of Mind (ToM) and literacy is increasingly being recognized in the literature. However, the focus to date has concentrated on the connections between reading and ToM, with an emphasis on the ways in which ToM is implicated in making inferences from text and suggestions that engaging in reading fiction can support the development of ToM. The exploratory study presented in this paper is unique in its approach as it widens the focus to consider the relationship between ToM and writing. Using a developmental framework based on the work of Westby and Robinson (Westby, C. & Robinson L. (2014). A developmental perspective for promoting theory of mind. Topics in Language Disorders 34 (4), 362–382 doi: 10.1097/TLD.0000000000000035), the written narratives of 43 deaf children (aged 7.2 years to 11.11 years) were examined for evidence of ToM. Evidence of ToM was found in the writing of 86% of the participants (n = 37) with children demonstrating abilities across the spectrum of development. Implications for both research and pedagogical practice are discussed.
