Studied 2 1/2- to 6-year-old children's judgments of age category and relative age of stimulus faces, using a paired-comparison task. Faces showed variations in craniofacial profile shape, frontal face feature vertical placement, and facial wrinkling. (Author/NH)

Describes two experiments that assessed young children's understanding of the characteristic uncertainty in the physical nature of random phenomena as well as the unpredictability of outcomes. (HOD)

Tests the distinction between inferring new categories on the basis of property information (predicted to be difficult) and inferring new properties on the basis of category information (predicted to be easier) among 57 preschool children. (HOD)

A series of six experiments compares young children's competence in attributing absence of knowledge (ignorance) to their competence in attributing a false belief to the other. (HOD)

Examines developmental change in 4- 7- and 10-month-old infants' perceptions of correlations among attributes to determine whether relational information plays a role in abilities ranging from the perception and recognition of a simple pattern to the formation of a category. (HOD)

Examines the ability to differentiate appearance-reality and Level Two perspective-taking in tactile modality among a total of 92 children aged two-four years in three studies. The results indicate that three-year-olds find tactile appearance-reality and Level Two perspective-taking tasks easier than visual ones. (RJC)

Tests four hypotheses to separate the effect of schemes from drawing-specific influences on young children's drawings and examines whether copies and anticipatory drawings are influenced by schemes in the same manner. (HOD)

Explores longstanding inconsistencies in Piaget's account of development of spatial representation and perspective-taking. Examines Piaget's early writings and the findings of the original "three mountains" experiment. Concludes that Piaget's alternative theory is compatible with contemporary thinking and is important as a contributory…

Investigates effects of perceptual salience and specific orientation values on 16 kindergarten and fourth-grade children executing a speeded sorting task. Kindergarten results supported the cognitive processing prediction that orientation sorting times would vary as a function of condition, but no differences were obtained for the fourth-grade…

Second and third graders and fifth and sixth graders were tested in a very large, unfamiliar environment to determine the relation of their knowledge of an abstract reference frame to performance on a spatial inference task. (HOD)

Examines children's understanding of what variables and relations are important in problem structures, and their use of these variables and relations in problem solving. (HOD)

Investigates ability of nine-month-old infants to imitate simple actions with novel objects. Looks at both immediate and deferred imitation. Findings show that imitation in early infancy can span wide enough delays to be of potential service in social development. (Author/RWB)

Examines the fallacies about the nature of abilities and learning and about the interaction between sense modalities which follow from the dichotomy in relation to explanations of spatial development in the blind. Suggests that interactions between cognitive and perceptual factors need to be considered to explain more adequately effects of sensory…

Reviews the research literature on the abilities of infants to categorize visual information on dot patterns; schematic faces; hue; and orientation. (HOD)

Describes two studies in which young children were shown pictures that represented sound with postures and contexts, with conventions, and with combinations of information. Shows that the different types of pictorial representation of sound were not equivalent in their ability to evoke a correct interpretation. (HOD)
