Theory of Mind Development in Children with Visual Impairment: The Contribution of the Adapted Comprehensive Test ToM Storybooks.

Research that focused on Theory of Mind (ToM) development in blind children showed that they were delayed, but not permanently deficient, in various types of false belief tasks. More recent studies reported first evidence of typical ToM development in blind children and suggested that more comprehensive tools to evaluate ToM had to be used. The current paper analyzed ToM development in blind children, using the adapted version of the ToM Storybooks; this is a standardized comprehensive test developed to provide a reliable and stable measurement, in comparison with the false belief tasks. Results showed that blind children's ToM performances were very similar to the ones of matched typically developing children, matched on chronological age and gender. The current finding supported the importance of the use of a more comprehensive tool to assess ToM in atypical population.
