Children can recognize patterns much earlier than they can reconstruct them. A child cannot understand seriation in an operational sense unless he recognizes a seriated configuration. (ST)

Data suggest that young infants (110-130 days old) process distinctive features of objects that continuously change orientation. The importance of these findings for theories of cognitive and perceptual development of infants is discussed. (Author/DB)

Two experiments investigated the role of continuity cues in infants' perception of launching events as causal. Results indicated that younger subjects' perceptions of the particular object may influence perception of causality and that infants' use of cues to causality changes with age. (WP)

Three experiments assessed the ability of 2 to 5-year-old children to infer, under very simple task conditions, what another person sees when viewing something from a position other than the children's own. (ST)

Preliminary report of a longitudinal study. (ST)

Results support view that development of part-whole perception is mediated by logiclike perceptual regulations. (MH)

Five experiments involving children of 4-11 years investigated partonomic knowledge and its relation to the use of taxonomic organization. Results suggest that children are sensitive to parts of common objects and appear to be able to use this sensitivity to group objects in abstract, function-based, superordinate categories. (RJC)

Examines preschoolers' understanding of non-observable causal mechanism in causes of illness. Three studies were conducted using subjects from university child care centers. Subjects average five years of age. Results indicated that preschoolers recognize that appearances may be deceiving when it comes to judging causes of illness. Discusses…

Four experiments utilizing the familiarization-novelty preference procedure examined whether 3- and 4-month-olds could form categorical representations for cats versus dogs from the perceptual information available in silhouettes. Findings indicated that general shape or external contour information centered about the head was sufficient for…

Current work has yielded differential findings regarding infants' ability to perceptually detect the causal structure of a means-end support sequence. Resolving this debate has important implications for perception-action dissociations in this domain of object knowledge. In Study 1, 12-month-old infants' ability to perceive the causal structure of…

This article examines how children's construction of relationships in exploring materials helps to explain the constructivist foundations of the Reggio Emilia approach. A quasi-naturalistic study of 12 preschool children, ages 3 and 4 years, individually exploring different kinds of collage papers reveals a range of constructivist categories…

Explored differential cognitive-perceptual distortion in depression for adolescent (N=25) versus adult female (N=25) psychiatric inpatients with diagnosis of neurotic or reactive depression. Results from Beck Depression Inventory indicated significant similarities between groups in anger at self and sense of failure. Results also indicated several…

Recognition by infants, 13 and 22 weeks old, was tested by pairing novel stimuli with the familiarization stimulus at different points in an experimental session. Younger subjects showed no recognition of either two- or three- dimensional stimuli. Older subjects demonstrated more recognition in the three-dimensional condition. (MS)

Human infants' discrimination of changes in internal and external elements of compound visual patterns was investigated in four experiments employing a familiarization-novelty paradigm in which visual reinforcing patterns were presented contingent upon rate of high-amplitude nonnutritive sucking. (Author/JH)

Investigated developmental changes in children's judgments of age of people in photographs with emphasis on judgments correlating age and physical size. Results were discussed in terms of previous age perception studies and Piagetian Theory. (DP)
