Investigates the responsiveness of 14- and 20-week-old infants to binocular information using a stereoscopic shadow caster showing an object approaching on a collision course. (Author/SS)

Three experiments investigated four-month-old infants' capacity to perceive bimodally specified events by detecting the temporal synchrony of sound bursts with the visable impacts of surfaces. (Author/SS)

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…

Examined the contribution of specific contextual attributes to six-month-old infants' recognition of a well-learned cue. Infants did not encode contextual information in a holistic manner. The perceptual identification of contextual cues that were represented in the memory of an event was requisite for the retrieval of the memory. (GLR)

This study compared role of motion in adults' and infants' perception of object unity. Findings favored ecologically-oriented accounts of object perception. Motion was a determinant of object unity for infants. Alignment and common motion contributed to adults' object-unity perception; synchronous color changes did not. Infants detected…

Four experiments examined the perceptual features used by 4.5- to 11.5-month olds to individuate objects involved in occlusion events. Results indicated that 4.5-month olds used shape and size features to individuate objects in occlusion events. By 7.5 months, infants used pattern, and by 11.5 months, they used color to reason about object…

Compared the recognition, perceptual saliency, and naming of color to that of other perceptual object attributes in 2- to 5-year-olds as a function of language age. Found that although color was perceptually salient relative to other visual attributes, no selective impairment to color cognition was found relative to motion, form, and size.…

Although it is acknowledged that adults integrate features into a representation of the whole face, there is still some disagreement about the onset and developmental course of holistic face processing. We tested adults and children from 4 to 6 years of age with the same paradigm measuring holistic face processing through an adaptation of the…

This paper deals with research on the development of infants' ability to perceive invariant features of things and the relation of objects to both the spatial layout of the infants' environment and to themselves. Basic assumptions regarding the perception of invariance are discussed and a theoretical view of the role of motion in the development…

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)

The span of apprehension (a measure of the amount of information processed simultaneously from a brief visual display) was studied in two experiments involving 40 normal and learning disabled boys (ages 6-11 years). (Author/DLS)

Results showed that 2- and 3-dimensional forms affected 4- and 8-week-old infant visual behavior differently. (Author/JMB)

Two studies: (1) assessed the infant's ability to perceive differences between two-dimensional and three-dimensional stimuli; and (2) tested the infants' ability to transfer responses across dimensions. (Author/SB)

Examined length of fixation time responses of neonates to pairs of red, blue, and green acetate stimuli. (Author)
