Children 5 to 11 were given Piagetian spatial perspective tasks in a study of the development of egocentrism. Results indicated a more complex development of egocentrism than earlier Piagetian studies have suggested. (ST)

Two studies investigated how 5- to 10-year-olds integrate perceptual causality with their knowledge of the underlying causal mechanism, using two devices in which a bell would ring when a ball was dropped in, either immediately or after a delay, depending on the mechanism inside. Findings suggest a link between temporal contiguity and causality in…

Corneal infrared photography was used to record the visual fixations of 24 infants (4-6 weeks and 10-12 weeks) exposed to simple geometric figures. The results are discussed in relation to developmental changes in responsiveness to visual figures and in increasing ability to process information. (JMB)

Young children were given tasks in which they were to identify small variations in complex patterns. Results indicated the children were able to perform the task more accurately than developmental models would have predicted. (ST)

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)

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)

Preliminary report of a longitudinal study. (ST)

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)

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)

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)

This study was designed to determine the age relationships for each type of perceptual strategy used by nonconserving children during tests of conservation of quantity. The results indicate that the type of perceptual strategy reflected in children's answers varied with their age. (JMB)

Two experiments investigated whether 5-month olds would look longer at rotating "drawbridge" appearing to violate physical laws because they knew it was causally impossible. Findings indicated that infants' longer gaze at 180-degree rotations was due to simple perceptual preference for more motion, challenging Baillargeon's (1987) claim…

This study investigated the development of perceptual, cognitive, and affective perspective taking in 167 kindergarten through sixth grade children. Task intercorrelations were low, nonsignificant, and inconsistent, supporting the view that perspective taking is a multidimensional social-cognitive construct. (JMB)

Empirically describes the relative development of perceptual and conceptual understanding of left-right, back-front, up-down projective relationships between objects and provides a heuristic model of the cognitive processes involved in coordination of perspectives tasks. (Author/ED)

The relationship between children's perceptual, cognitive, and affective perspective-taking scores and their cognitive perspective-taking scores gathered one year later was assessed. Subjects were 56 kindergarten through third-grade children. (Author/JMB)
