Quinn, Paul C.; Bomba, Paul C. – Journal of Experimental Child Psychology, 1986
Studies of orientation perception in infants and children have revealed an "oblique effect," that is, a performance advantage for tasks involving horizontal and vertical stimulus orientations compared with tasks involving oblique orientations. The two studies reported support the hypothesis that oblique stimulus orientations are treated…

Stucki, Markus; And Others – Journal of Experimental Child Psychology, 1987
Results indicate that infants are able to recognize a human face from a specific motion pattern even when the face lacks static facial features. (PCB)

Adams, Russell J.; And Others – Journal of Experimental Child Psychology, 1986
Two experiments assessed the extent of newborns' ability to discriminate color. Results imply that newborns have some, albeit limited, capacity to discriminate chromatic from achromatic stimuli, and hence, are at least dichromats. (Author/DR)

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)

Streri, Arlette; Pecheaux, Marie-Germaine – Child Development, 1986
Investigates whether tactual habituation without the assistance of vision occurs in four- to six-month-old infants. Additionally tests the relevance of a habituation/reaction to novelty procedure in the tactual modality. Results show clearly that tactual habituation occurs in such infants, just as visual habituation does. (Author/RH)

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.

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)

Bornstein, Marc H.; And Others – Journal of Experimental Child Psychology, 1986
Two variants of the habituation paradigm were used to investigate fine orientation discrimination and shape constancy in 34 young infants. Results demonstrate that conditions determine whether young infants show sensitivity to relatively fine variations in pattern orientation or give evidence of shape constancy with the same patterns.

Bornstein, Marc H.; Krinsky, Sharon J. – Journal of Experimental Child Psychology, 1985
Four experiments assessed converging aspects of four-month-old infants' perceptions of visual patterns. Results together corroborate and extend previous findings that vertical symmetry has a special status in early perceptual development and that infants can perceive pattern wholes. (Author/AS)

Slater, Alan; And Others – Journal of Experimental Child Psychology, 1985
Three experiments are described which relate to models of infant visual preferences and to the ways in which preferences can be modified or created by habituation. Results suggest that the Banks and Salapatek's contrast sensitivity model can be a powerful predictor of preferential looking in newborns and that preferences based on experience can be…

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)

Kaufmann-Hayoz, Ruth; And Others – Child Development, 1986
Examines 3-month-old infants' perception of "camouflaged" forms that were only visible when moving. Shows infants effectively use kinetic information to organize visual input in higher-order structures. (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.…

Meltzoff, Andrew N. – Child Development, 1988
Investigates ability of nine-month-old infants to imitate simple actions with novel objects. Looks at both immediate and deferred imitation. Findings show that imitation in early infancy can span wide enough delays to be of potential service in social development. (Author/RWB)

Quinn, Paul C.; Eimas, Peter D. – Merrill-Palmer Quarterly, 1986
Reviews the research literature on the abilities of infants to categorize visual information on dot patterns; schematic faces; hue; and orientation. (HOD)
