This study establishes a sequence of developing mental state understandings in infants. We used three violation-of-expectation paradigms to assess fifty-seven 16-month-olds' ability to (a) infer an actress's intention from her prior repeated approaches to an object, (b) recognize her emotion by watching her facial-emotional display, and (c) deduce…

The ability of 3- and 4-year-old children to disregard advice from an overtly misleading informant was investigated across five studies (total "n" =212). Previous studies have documented limitations in young children's ability to reject misleading advice. This study was designed to test the hypothesis that these limitations are primarily…

In two studies, we investigated preschoolers' ability to use others' preferences to learn names for things. Two studies demonstrated that preschool children make smart use of others' preferences. In the first study, preschool children only used information about others' preferences when they were clearly linked to referential intentions. The…

Two experiments investigated preschoolers' understanding of the relation between pretending and intentional action. In Experiment 1, both 3- and 4-year olds recognized that characters whose actions were intended as pretense were pretending. However, children also judged that characters whose actions gave them the appearance of an entity…

The present study investigated event-based prospective memory in five age groups of preschoolers (i.e., 2-, 3-, 4-, 5-, and 6-year-olds). Applying a laboratory-controlled prospective memory procedure, the data showed that event-based prospective memory performance improves across the preschool years, at least between 3 and 6 years of age. However,…

Two studies examined the hypothesis that children rely on name representations, often indexed by shape, in their semantic representations. Results suggest that, although shape plays an important role in children's early naming, other factors are also important, including the mental state of the picture's creator (whether intentional or not).…

This study investigated children's responses to failed attempts at reaching possible and impossible goals, and their beliefs about the efficacy of wishing as a magical solution in such situations. Preschoolers were presented with failure scenarios in three different formats: a standard picture book presentation, scenarios enacted in real life by…

This research investigated 3- to 5-year-old's understanding of the role of intentional states and action in pretense. There are two main perspectives on how children conceptualize pretense. One view is that children understand the mental aspects of pretending (the rich interpretation). The alternative view is that children conceptualize pretense…

To clarify the nature of the social cognitive skills involved in preschoolers' reenactment of actions on objects, we studied 31- and 41-month-old children's reenactment of intended acts (''failed attempts'') in Meltzoff's [Meltzoff, A. N. (1995)]. Understanding the intentions of others: Reenactment of intended acts by 18-month-old children.…

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…

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)

Three studies explored the scope of preschoolers' teleological tendency to view entities as "designed for purposes." Found that preschoolers, unlike adults, tend to attribute functions to all kinds of objects. Both children and adults predominantly viewed an object's function as the activity it was designed to perform. (Author/KB)

Examined relationships among theory of mind construct of intention and false belief, problem-solving ability, metacognitive regulation, and strategy use in 39 preschoolers. Found significant correlations between strategy use and theory of mind, and metacognitive regulation and theory of mind. A moderate, but nonsignificant, correlation was found…

Examined preschoolers' understanding that a statement's surface meaning may differ from actual meaning. Found that even 3-year-olds rejected a lie-teller's statement as reflecting his true beliefs and knowledge, indicating basic expression-representation differentiation. Found that most 4- and 5-year-olds and some 3-year-olds knew that a lie may…
