For several decades, there has been an interest in understanding how Emotion Comprehension (EC) and Theory of Mind (ToM) are related during the preschool years. In addition, the links between language and ToM and language and EC have been studied. Although prior work shows the influence of language on ToM and EC, the relationships among these…

The ability to understand the mental states of other individuals is central to human social behavior, yet some theory of mind capacities are shared with other species. Comparisons of theory of mind skills across humans and other primates can provide a critical test of the cognitive prerequisites necessary for different theory of mind skills to…

Does language have a role to play in conceptual development, and if so, what is that role? Understanding the contents of another person's mind parallels the development in early childhood of mental state language. Does the conceptual understanding get reflected in and drive the language development, or does the language allow the representation of…

Holding content explicitly requires a form of self-knowledge. But what does the relevant self-knowledge look like? Using theory of mind as an example, this paper argues that the correct answer to this question will have to take into account the crucial role of language-based deliberation but warns against the standard assumption that explicitness…

Based on anticipatory looking and reactions to violations of expected events, infants have been credited with "theory of mind" (ToM) knowledge that a person's search behaviour for an object will be guided by true or false beliefs about the object's location. However, little is known about the preconditions for looking patterns consistent…

Relations among indices of maternal mind-mindedness (appropriate and nonattuned mind-related comments) and children's: (a) internal state vocabulary and perspectival symbolic play at 26 months ("N" = 206), and (b) theory of mind (ToM) at 51 months ("n" = 161) were investigated. Appropriate comments were positively…

The hypothesis that language plays a role in theory-of-mind (ToM) development is supported by a number of lines of evidence (e.g., H. Lohmann & M. Tomasello, 2003). The current study sought to further investigate the relations between maternal language input, memory for false sentential complements, cognitive flexibility, and the development of…

Executive function mechanisms underpinning language-related effects on theory of mind understanding were examined in a sample of 165 preschoolers. Verbal labels were manipulated to identify relevant perspectives on an explicit false belief task. In Experiment 1 with 4-year-olds (N = 74), false belief reasoning was superior in the fully and…

In this study the authors investigated whether training preschool children in the use of mental state lexicon plays a significant role in bringing about advanced conceptual understanding of mental terms and improved performance on theory-of-mind tasks. A total of 70 participants belonging to two age groups (3 and 4 years old) were randomly…
