Dannemiller, James L.; Hanko, Staphanie A. – Journal of Experimental Child Psychology, 1987
Study tests 45 four-month-old infants for color constancy using a familiarization, paired-comparison paradigm. Infants tested with a change in illuminant correctly recognized the familiar color under some conditions and failed to do so under others. (Author/RWB)

Maurer, Daphne; and Adams, Russell J. – Journal of Experimental Child Psychology, 1987
Two different methods which minimize achromatic cues were used to test the ability of one-month-olds to discriminate gray from broadband blue. Test data imply an improvement between birth and one month of age in the discrimination of gray from broadband blue. Possible physiological changes underlying this improvement are discussed.

Pezdek, Kathy – Child Development, 1987
Assessed the effect of the amount of physical detail in pictures on the picture recognition memory of 7- and 9-year-olds, young adults, and adults over 68. For each age group, recognition accuracy was significantly higher for pictures presented in the simple rather than the complex form. (PCB)

Dannemiller, James L.; Stephens, Benjamin R. – Child Development, 1988
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)

Lewis, Terri L.; Maurer, Daphne – Child Development, 1986
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)

Rose, Susan A.; Feldman, Judith F. – Developmental Psychology, 1987
Examined the stability of two aspects of infant visual attention derived from the paired-comparison procedure in infants tested at 6, 7, and 8 months of age. The two aspects were novelty preference and exposure time. Suggests that both novelty and exposure-time scores reflect moderately stable but independent characteristics of infant behavior.…

Pipp, Sandra; Haith, Marshall M. – Journal of Experimental Child Psychology, 1984
Visual fixations were recorded in newborn, 4-, and 8-week-old human infants as they scanned displays that varied in contour length, size, number, and a new metric, CVAL (based on Contour Variability, Amount and Location). One of the findings was that both contour length and CVAL separately accounted for approximatel1 95 of looking-duration…

Bornstein, Marc H.; Stiles-Davis, Joan – Developmental Psychology, 1984
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…
