This study assessed the extent to which visuospatial processing, as measured by visual scanning behaviour, was associated with infants' ability to recognize mirror image and structurally distinct three-dimensional objects. Simplified Shepard and Metzler (1971) images were employed. Using a remote eye-tracker, infants ages 10 to 17 months (n = 130)…

Two preferential-reaching experiments explored 5- and 7-month-olds' sensitivity to pictorial depth cues. In the first experiment, infants viewed a display in which texture gradients, linear perspective of the surface contours, and relative height in the visual field provided information that two objects were at different distances. Five- and…

Examined infants' ability to locate an invisible target after instrumental and association training. After instrumental training, localization was dependent on visual cues, whereas after association training, it occurred with or without visual cues. Concluded that an updating strategy based on proprioceptive information is operative from the…

Compares monocular depth perception with binocular depth perception in five- to seven-month-old infants. Reaching preferences (dependent measure) observed in the monocular condition indicated sensitivity to monocular depth information. Binocular viewing resulted in a far more consistent tendency to reach for the nearer object. (Author)

An Ames static trapezoidal window was used to test infants' responsiveness to pictorial depth. Sensitivity to the pictorial information for depth that is present in the trapezoidal window appears to develop after the age of 22 weeks. (Author/DB)

A total of eighty 9-month-old infants were presented with a problem consisting of several different conditions which separated response, position on a table, and absolute spatial position as factors leading to errors in search for hidden objects. (MS)

Three experiments investigated use of visual input and body movement input arising from movement through the world on spatial orientation. Experiments involved infants searching for a toy hidden in one of two containers. Findings indicated that search was best after infant movement in a lit environment prior to searching; all other conditions led…

The current research investigates infants' perception of a novel object from a category that is familiar to young infants: key rings. We ask whether experiences obtained outside the lab would allow young infants to parse the visible portions of a partly occluded key ring display into one single unit, presumably as a result of having categorized it…

The development of sensory and perceptual ability in infants is an important area of infancy research. This book reflects current knowledge of perceptual development and points to some of the many questions that remain unanswered. The book is divided into four parts. Part 1, "How the Visual System Develops: Normal and Abnormal…
