Congruency as a Nonspecific Perceptual Property Contributing to Newborns' Face Preference
Peer reviewed Peer reviewed
Direct linkDirect link
Cassia, Viola Macchi; Valenza, Eloisa; Simion, Francesca; Leo, Irene – Child Development, 2008
Past research has shown that top-heaviness is a perceptual property that plays a crucial role in triggering newborns' preference toward faces. The present study examined the contribution of a second configural property, "congruency," to newborns' face preference. Experiments 1 and 2 demonstrated that when embedded in nonfacelike stimuli,…

Perceptual Completion in Newborn Human Infants

Valenza, Eloisa; Leo, Irene; Gava, Lucia; Simion, Francesca – Child Development, 2006
Despite decades of studies of human infants, a still open question concerns the role of visual experience in the development of the ability to perceive complete shapes over partial occlusion. Previous studies show that newborns fail to manifest this ability, either because they lack the visual experience required for perceptual completion or…

Auditory-Visual Coordination in Neonates
Peer reviewed Peer reviewed
McGurk, Harry; And Others – Child Development, 1977
In these two studies, neonatal oculomotor behavior was observed under various conditions of visual and auditory stimulation. Findings showed auditory and visual perception to be relatively independent during the neonatal period. (Author/JMB)

Smooth-Pursuit Eye Movements in the Newborn Infant.
Peer reviewed Peer reviewed
Kremenitzer, Janet Pickard; And Others – Child Development, 1979
The capacity of newborn infants for smooth-pursuit eye movements in single-target tracking and in optokinetic nystagmus to a moving striped field was examined utilizing DC electrooculography. (JMB)

Perception of Numerical Invariance in Neonates.
Peer reviewed Peer reviewed
Antel, Sue Ellen; Keating, Daniel P. – Child Development, 1983
Examines the ability of infants ranging in age from 21 to 44 hours old to discriminate among visual stimulus arrays. Infants were able to discriminate between small sets of dots (two to three dots) but not between larger sets (four to six). (Author/MP)

Posture as a Determinant of Visual Behavior in Newborns
Peer reviewed Peer reviewed
Fredrickson, W. Timm; Brown, Josephine V. – Child Development, 1975
The effects of posture on the visual behavior of 15 3-day-old healthy, black, newborn infants were assessed. Findings suggest that the vestibular, proprioceptive, and contact stimulation provided by the on-shoulder position affects the newborn's ability to follow and process visual stimuli. (Author/CS)

Newborn Infants' Visual Responses to Square Wave Gratings
Peer reviewed Peer reviewed
Slater, Alan; Sykes, Margaret – Child Development, 1977
A series of experiments is described whose aim was to define certain of the effective dimensions of stimulation in the newborn's visual environment. (Author/JMB)

Responses of Neonates to Colored Stimuli
Peer reviewed Peer reviewed
Jones-Molfese, Victoria J. – Child Development, 1977
Examined length of fixation time responses of neonates to pairs of red, blue, and green acetate stimuli. (Author)

The Relative Efficacy of Vestibular-Proprioceptive Stimulation and the Upright Position in Enhancing Visual Pursuit in Neonates
Peer reviewed Peer reviewed
Gregg, Claudette L.; And Others – Child Development, 1976
Forty-eight neonates were randomly assigned to view a moving stimulus either in the horizontal or the upright position, with or without added vestibular stimulation and with or without pacifier sucking. Results indicate that vestibular proprioceptive stimulation, provided horizontally or semi-vertically, significantly enhanced visual tracking.…
