Evaluates models of infant visual preferences with predictions based on the physical attributes of visual patterns using pairs of schematic faces and abstract patterns identical except for contrast reversals. Results suggest that a fundamental change in the determinants of visual preference occurs postnatally between 6 and 12 weeks. (Author/RWB)

Compares estimates of monocular visual resolution of children 6- to 36-months of age with three psychophysical procedures: the Probabilistic Estimation by Sequential Testing (PEST), a modification of the PEST procedure, and the method-of-constant stimuli. (HOD)

Studies the ability of 5-month-old infants to recall temporal information and use temporal organization by training them to fixate a hierarchically structured or unstructured sequence of stimuli which appeared in four spatial positions. Results are interpreted within a temporal organizational framework; infants appear to use organization within…

Three studies explore the development of discrimination and memory for symmetry in preschoolers four to six years of age. Issues addressed include the young child's ability to discriminate and reproduce symmetry, and the effects of pattern orientation and complexity on the young child's symmetry discrimination and reproduction. Results indicate…
