In the first of two tasks, 5- and 11-year-olds recalled the array location of social photographs of an unfamiliar adult expressing anger, disgust, fear, joy, and shame. In the second task, subjects were tested for their incidental recall of those features which were not previously isolated. Results indicated a mouth-eyes-nose hierarchy for…

The effectiveness of different training and transfer test conditions in promoting perceptual learning in impulsive kindergarten children was investigated. The results provide guidelines for designing effective training methods for improving discrimination learning and problem solving in impulsive children. (Author/SB)

Study attempted to determine the viability of optimal level theory as it pertains to infant perceptual and cognitive development. (Authors)

One- and two-month-old infants were shown schematic drawings of a human face with features arranged (1) naturally, (2) symmetrically but scrambled, and (3) asymmetrically and scrambled. Two-month-olds discriminated among all arangements and preferred the natural arrangement; one-month-olds showed no discrimination or preference. (Author/DB)

Investigated the development of classificatory organization. Two experiments examined age differences in children's spontaneous extensions of a classification and a third examined children's extensions under hypothesis-testing instructions. (JMB)

Used a habituation-dishabituation procedure to test ability of 4-, 5-, and 7-month-olds to differentiate between a subjective ellipse and a nonsubjective pattern that were constructed by displacing the inducing elements of the illusory figure. Found that even 4-month-olds discriminated between the subjective ellipse and nonillusory display. This…

Investigated infants' integration of visual information across space and time. In four experiments, infants aged 12 months and 6 months viewed objects after watching light trace similar and dissimilar shapes. Infants looked longer at novel shapes, although six-month-olds did not recognize figures taking more than 10 seconds to trace. One-year-old…

An examination of the extent to which adults and children (7 and 11 years old) were able to make discriminations between fixations directed at their eyes and at different positions on their faces. (SDH)

In a study of spatial perspectives, third- and fifth-grade students were asked to coordinate perspectives on single-object and multiple-object arrays. (ST)

The present study was designed to identify sources of information in the human face and to determine how this information is processed by young children in solving problems. (ST)

Presents three experiments which investigated: (1) the nature of the processes by which preschool and kindergarten children estimate small numbers; and (2) the generality of the number-relevant versus number-irrelevant categorization scheme in the child's operative thinking about small numbers. (Author/ED)

First, third, and fifth graders made judgments of the geographical slant of surfaces depicted in photographs while optical slant and postural orientation were manipulated. The results indicated the existence of a linear mechanism which compensates for the effect of postural inclination. (JMB)

This study examined the hypothesis that differences in performance of impulsive and reflective children on the "20 questions" test are due to individual differences in preferred perceptual processing strategy rather than in cognitive maturity of problem-solving strategy. (Author/JMB)
