This study investigated 2-year-olds' understanding of others' intentions in a social learning context. After seeing a demonstration of how to open a box, children in two "No Prior Intention" conditions were less likely than those in "Prior Intention" conditions to open the box themselves when the adult unsuccessfully tried to open it. Results…

To assess children's understanding of intentions as distinct from desires, this study presented 3- to 7-year-olds and adults with situations in which intentions were satisfied but desires were not, or vice versa, in a story-comprehension task and target-hitting game. Findings indicated that younger children were unable to differentiate desires and…

Three experiments examined 3- to 5-year olds' understanding of the intended nature of pretend behavior. Found that 4-year olds understood intention as a mental cause of action and construed pretend behaviors mentalistically, but systematically associated ignorance of a specific animal with pretending to be that animal. Concludes that Lillard's…

Offers suggestions for future investigations of theory-of-mind development. Maintains that there needs to be: (1) greater focus on the development of understanding of desire and intention; (2) research on the role of language in theory-of-mind development integrating representational-development and social-interaction views; and (3) investigation…

Five experiments tested whether children understand pretense intentions before they understand pretense mental representations. Findings revealed that children did not understand that intention is crucial to pretense. Various methodological factors that might have compromised results such as force choice versus yes-no questions or using a…

Maintains that Lillard's and Joseph's articles provide an example of how apparently divergent empirical results may turn out to reflect interesting differences between children and adults. The researchers agreed that for young children, pretense is often, but not necessarily, intentional and neither found evidence for a representational…

To determine whether children younger than four have an authentic theory of mind, studies relying on deceptive hiding measures for indexing false belief were carried out. Children accurately anticipated the impact of deceptive strategies on the behavior and belief of opponents and used information management to help and hinder others' efforts. (BC)

Children's ability to remember and report past mental states was examined. Four-year olds were able to report all past mental states. Three-year olds reported past pretenses, images, and perceptions well; desires and intentions with moderate difficulty; and beliefs with great difficulty. (BC)
