The future of theory-of-mind research: understanding motivational states, the role of language, and real-world consequences.

Suggestions are made for future investigation of theory-of-mind development. There needs to be (1) more focus on the development of understanding of desire and intention; (2) research on the role of language in theory-of-mind development that integrates representational-development and social-interaction views; and (3) investigation of the real-world consequences of children's developing understanding of belief, desire, and intention.
