A test for sensitivity to binocular disparity and a shape perception test were administered to four-month-olds. Results indicated that disparity-sensitive infants could perceive three-dimensional-object shape from kinetic and binocular depth information. (PCB)

A total of 20 infants either five or seven months of age viewed computer-generated random-lot displays in which accretion and deletion of texture provided the only information for contours. Infants of both age groups showed significant preferences to reach for the apparently nearer regions in the displays. (Author/RH)

Examines, in two experiments, 5-month-old infants' sensitivity to auditory-visual specification of distance and direction of movement. One experiment presented two films with soundtracks in either a match or mismatch condition; the second showed the two films side-by-side with a single soundtrack appropriate to one. Infants demonstrated visual…

Results of three experiments support the generalization that early perception of object unity depends on perceived motion, and that the class of effective motions includes, at least, the rigid translations of an object in three-dimensional space. Effective motions may be specified by very different sources of stimulus information. (RH)

Examines the ability to differentiate appearance-reality and Level Two perspective-taking in tactile modality among a total of 92 children aged two-four years in three studies. The results indicate that three-year-olds find tactile appearance-reality and Level Two perspective-taking tasks easier than visual ones. (RJC)

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)

In comparison with full-term infants, seven-month-old high-risk preterm infants exhibited deficits in visual recognition memory and in the ability to recruit, sustain, and shift attention. (RH)

In contrast with controls and newborn presented with static models, only newborn presented with dynamic models reproduced the models' actions at significant levels. Infants in the static condition fixated the experimenter longer than those in the dynamic one. Results are discussed in terms of neurophysiological findings concerning the control of…

Tested and confirmed, in three experiments, the hypothesis that children's interpretation of pictorial conventions and of the expression "look like" may increase their tendency toward intellectual realism. That is, a tendency to respond to requests for perceptual reports by indicating what is known about an object or array, rather than…

Infants were tested for their discrimination of changes in the melodic contour (direction of successive pitch changes) of brief melodies in the context of discernible variations in key or interval size. (PCB)

Male and female nonparent adults rated tape-recordings of initial, middle, and final 10-second segments of pain and hunger cries on four 7-point Likert-type scale items describing how urgent, arousing, aversive, and sick cry segments sounded. Results suggest that different segments of cries resulting from the same stimulus provide different…

Studies children's inductive inferences in order to investigate the development of the expectation that members of a category share unforeseen properties. Results indicate that preschoolers drew more inferences based on category membership than on perceptual appearances. (PCB)

When 96 mothers and 46 fathers of 6- or 13-month-old infants independently generated behavioral cues they believed contributed to their perception of their infant's recent easiness/difficultness, few systematic differences were found between easy and difficult infants, 6- and 13-month-olds, males and females, and firstborn and later-born.…

Groups of 17-, 23-, and 29-week-olds were habituated to slides of women posing facial expressions varying display of teeth affect; subjects were then shown slides of women posing the familiarized expressions plus a toothy smiling expression. In a second experiment older subjects also proved to be insensitive to affect-related aspects of still…

Investigated relationships between mothers' perception of infants temperament at 6 months and their behavior toward their infants at 6 and 12 months of age among 40 firstborn Israeli infants. Temperamental intensity ratings were related to auditory stimulation and contingent positive vocalization for girls and to increased physical contact for…
