Perception of Object Unity in Young Infants: The Roles of Motion, Depth, and Orientation.
Peer reviewed Peer reviewed
Johnson, Scott P.; Aslin, Richard N. – Cognitive Development, 1996
Two experiments examined the effects of common motion, background texture, and orientation on four-month olds' perception of unity of a partially occluded rod. Results indicated that infants' perception of object unity is not dependent on a single visual cue but on a variety of cues including motion, interposition, depth cues, background texture,…

Perception of Auditory-Visual Distance Relations by 5-Month-Old Infants.
Peer reviewed Peer reviewed
Pickens, Jeffrey – Developmental Psychology, 1994
Sixty-four infants viewed side-by-side videotapes of toy trains (in four visual conditions) and listened to sounds at increasing or decreasing amplitude designed to match one of the videos. Results suggested that five-month olds were sensitive to auditory-visual distance relations and that change in size was an important visual depth cue. (MDM)

Infants' Responsiveness to Line Junctions in Curved Objects.
Peer reviewed Peer reviewed
Kavsek, Michael J. – Journal of Experimental Child Psychology, 1999
Studied infant ability to extract depth information from a three-dimensional structure. Found evidence that 8-month-old infants distinguished between lines indicating edges, and lines indicating markings, and that they are able to use line junctions to perceive line drawings as depicting three-dimensional objects in the picture plane.

An Emphasis on Perception: Teaching Image Formation Using a Mechanistic Model of Vision.

Allen, Sue; And Others – 1995
An effective way to teach the concept of image is to give students a model of human vision which incorporates a simple mechanism of depth perception. In this study two almost identical versions of a curriculum in geometrical optics were created. One used a mechanistic, interpretive eye model, and in the other the eye was modeled as a passive,…

Eye Movements and Visual Function in Infancy: The Problem of Interdependence.
Mitkin, A. – 1987
Reported are three series of experiments analyzing the development of the visual function of infants. The first experimental series was aimed at the investigation of infants' reaction to moving objects. The second experimental series dealt with the analysis of the development of binocular vision in infants. The goal of the third series was to…

Infants' Coordination of Auditory and Visual Depth Information.
Peer reviewed Peer reviewed
Morrongiello, Barbara A.; Fenwick, Kimberley D. – Journal of Experimental Child Psychology, 1991
Infants of five, seven, and nine months were shown two video images on monitors placed side by side. Images were accompanied by a soundtrack that matched one of the images. Results indicated that age-related changes in infants' coordination of auditory and visual depth information took place between the ages of five and nine months. (SH)
