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)

Report on the effects of an industrial training program in developing interactive skills, carried out by BOAC. (GB)

The author reviews the controversy over definitions of learning disabilities and posits two "givens" in any defintion of the condition: that all learning is neurological, and that learning is conditioning. He proposes a definition based on neuropsychological dysfunction which can be translated into an educational regimen. (CL)

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)

The paper reviews research efforts directed at identifying perceptual and cognitive components in reading and their dysfunction in disabled readers. Disruption in the processing sequence is identified, and a compensatory training technique for the reading disabled is described. (Author)

Middle class children and adults (n=632) from eight age levels (mean ages 8, 9, 10, 11, 13, 17, 19 and 33 years) were tested with the Profile of Nonverbal Sensitivity (the PONS test) to measure accuracy in decoding nonverbal cues. The prediction that nonverbal skills would increasingly differentiate over ages was confirmed. (RH)

The relation between Matching Familiar Figures Test performance and Piaget's construct of perceptual activity was examined with 48 third- and fourth-grade boys. (SB)

The analysis of I-scale preference orders of 71 infants (2 to 9 months old) to four face-like stimuli suggested a common J-scale stimulus ordering for each of four age groups. Changes in I-scale frequencies were used as a measure of age-related changes in preference orders. (MS)

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)

Examined rate-based intersensory matching in infants by habituating them to concordant or discordant auditory-visual stimuli. Found a preference for the visual stimulus that moved at a novel velocity, indicating that the temporal attributes of the visual component dominated responsiveness. Found only limited evidence of intersensory matching. (WP)

In three experiments, three- and four-year olds were asked to map relative size from one array of objects to another, map relative size to relative proportion, and map relative size to a variety of perceptual dimensions. Children were able to make relational mappings based on size when spatial positions and concrete representations of size of…
