In a series of studies on delayed recognition and forgetting, the failure of 22-week-old infants to recognize which face photo (e.g, man or woman) had been previously exposed was shown to be influenced by what the infant saw during a retention interval. (Author/JMB)

This study tested the effects of moderately intense square-wave tone on the nutritive sucking pattern of neonates. (Author/SB)

Two studies examined infants' understanding of spatial relations during the period following attainment of active search for hidden objects. (Author/SB)

Tested infants' understandings of self and mother in the domains of agency and featural knowledge. Four developmentally sequential tasks were administered to infants. It was hypothesized that infants would pass the mother versions of feature tasks before the self versions, and would pass the self versions of agency tasks before the mother…

Comments on a study by Schacter and others which proposes that insights into why infants make the AB error can be gained by examining the errors of brain-damaged adults on similar tasks. (The B in AB has a line over it in the title and in the article meaning "A not B.") (PCB)

Results suggest that temporal summation of brief stimuli is deficient in neonates. When compared with adult data from an analogous study, results also suggest that the transient system is immature in infants and that this immaturity is expressed in different ways by startle amplitude, probability, and latency.

Infants exposed to a set of artificially-created face stimuli having distinct mean and modal prototypes showed a pattern of behavior predicted by category abstraction models. Infants appeared to abstract, at the time of learning, a feature-count summary of the category displayed. (Author/RH)

Two experiments investigated infants' use of structural relations in dividing schematic drawings of animals into categories. Results demonstrated subjects' sensitivity to structural information like that thought by Rosch (1978) to exist in the natural world and their ability to segregate items into categories on the basis of clusters of correlated…

Parker and Gibson's developmental model of evolution of language and intelligence in early hominids is described and discussed; data from a comparative study of object manipulation in two apes and a human infant are reported; and, human ontogenic developmental retardation in locomotion is discussed in terms of its implications for the differential…

Overviews vital statistics data, emphasizing differences in health status between the Black and White populations with respect to specific diseases and mortality. Discusses major causes of death among US Blacks. (GC)

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…

In three experiments, 5-month-old infants discriminated between a perfectly contingent live display of their own leg motion and a noncontingent display of self or a peer. They showed this discrimination by preferential fixation of the noncontingent display. (Author/NH)

A set of studies examined infant categorization of the orientation of visual stimuli by establishing a categorization function for the orientation continuum; attempted to determine a perceptual boundary between "oblique" and "vertical"; and explored the relationship between discrimination abilities and the perceptual boundary.…

The microcomputer can be used as a perceptual tool that enables one to quickly manipulate information about a student, graphically depict such information, and formulate and test hypotheses. Applications of microcomputers to teaching handicapped infants, including examining contingencies of reinforcement, and data-based decision rules are…

Two experiments examined the effects of a change in a reinforcing stimulus's color on memory for an operant response in three- to four-month-old infants. (Author/RH)
