Patterns of development of ToM belief abilities in intellectually disabled (ID) children and typically developing (TD) children matched on their developmental age were investigated. The links between cognition, language, social understanding and ToM belief abilities were examined. EDEI-R [Perron-Borelli M. (1996). "Echelles Differentielles…

Three experiments studied preschoolers' understanding of false beliefs resulting from developmental misconceptions. Found that children showed some (but incomplete) mastery of Level 2 perspective taking, appearance-reality distinction, line of sight, and biological principles of growth and innate potential. Performance was comparable to that with…

Twelve- and 14-month-old infants' ability to represent another person's visual perspective (Level-1 visual perspective taking) was studied in a looking-time paradigm. Fourteen-month-olds looked longer at a person reaching for and grasping a new object when the old goal-object was visible than when it was invisible to the person (but visible to the…

In comprehending stories, adults create mental models from which they follow the actions of the characters from the characters' different mental vantage points. Using a novel methodology, this study is the first to examine when children attain the narrative ability to track the mental perspective of characters. That is, when do children follow…

The mechanisms underwriting our commonsense psychology, or "theory of mind", have been extensively investigated via reasoning tasks that require participants to "predict" the action of agents based on information about beliefs and desires. However, relatively few studies have investigated the processes contributing to a central component of…

In two experiments using a large scale space and a third using a model of that space, the ability of 3-, 4-, and 5-year-old children to coordinate two perspectives of a large scale space was examined. (Author/SB)

The social judgments of 75 subjects aged 11 and 75 aged 14 were compared using Peel's three categories of judgment to measure and evaluate responses. Clear, if limited, evidence for progress between the two ages in the ability to judge other people's perspectives was obtained, in line with Peel's general theory. (Author)

Retarded (N=24) and nonretarded (N=46) individuals matched on MA and CA were tested on role-taking, self-image, and imitation. The findings supported the view that role-taking ability is a function of cognitive level and that self-image and imitation are determined by both cognitive and experiential factors. (Author)

The results of this study indicated that 4- and 5-year-old children are able to engage in veridical conceptual perspective taking. Furthermore, it was concluded that the ability to make a correct inference develops somewhat earlier than the ability to justify that inference. (JMB)

Four experiments studied 4- to 6-year-old children's understanding of inferential reasoning as a source of knowledge. To assess understanding that knowledge of relevant premises leads to knowledge of the conclusion, children had to judge the knowledge of another person, who was presented to the child as being aware of two premises. (Author/BN)

Outlines how levels of the interpretation of reality and categories of a naive theory of action that constitute these levels are differentiated and coordinated in a specific developmental sequence. Subsumed within this theoretical framework are the distinction between action on physical objects and social interaction and the distinction between…

Investigates the relationships among the first three stages of cognitive, role-taking, and moral development in both transitional and nontransitional subjects ages 5 to 14 years in order to determine whether the pattern of associations conformed more adequately to the "functional unity" model or to the "necessary but not…

Investigated relationship between young children's ability to predict another observer's interpretation of an ambiguous picture and to identify the source of a misinterpretation after it had occurred. Found that six-year-olds were more likely than four- and five-year-olds to predict that a puppet would misinterpret the target-restricted view and…

Three experiments examined assumption that children attribute human properties to nonhuman agents. Two- to 8-year-olds participated in false-belief tests concerning human and various nonhuman agents, including animals and God, and in a modified perspective-taking task including nonhuman agents. Results suggested that children do not consistently…
