Compares the responses of 14 child abusers and a matched group of nonabusers to videotapes of crying and smiling infants. Psychophysiological and subjective self-report measures were taken. (SS)

To test the hypothesis that early intervention can enhance the development of high risk preterm infants, a prescribed multimodal sensory enrichment program, within a regional neonatal intensive care unit, was designed and implemented with 28 preterm infants.

Five experiments were conducted in order to determine what effect independent movement of an internal element has on the externality effect in young infants, and to consider the value of contrasting explanations of the effect itself. Subjects were 90 infants ranging in age from 28 to 49 days. (MP)

Investigates the relationship between cardiovascular reactions and five basic emotions, (interest, anger, fear, distress, and joy) exhibited by 40 9- and 12-month-old infants. (CM)

Suggests that the use of the operant conditioning paradigm, as it has been applied to infant social, vocal behavior, fails to take into account the social nature of human infants over and above the rigid theoretical rationale of the Paradigm. (MP)

Two experiments measured changes in binocular eye alignment from 1- to 6-month-old infants. Experiment 1 recorded these changes from 1-, 2-, and 3-month-olds, using corneal photography. Experiment 2 measured responses of 3-, 4 1/2-, and 6-month-olds as a wedge prism was placed alternately before each eye. (MS)

Discusses contributions of Adolph's study to behavioral knowledge; it is an important study of the early development of a universal basic pattern of human behavior, illuminating how humans perceive the possibilities for action and learn to use them when appropriate opportunities are offered. Notes that the study addresses generalization of newly…

Presented 9-month-old infants with slides of drawings of pigs and rabbits, and tested the relative success of two auditory accompaniments in facilitating subsequent categorization of the slides. Found that infants paid more attention to presentations when they were accompanied by sound (words or tones) rather than musical tones, and paid more…

Two experiments compared 6-month-olds' numerosity discrimination performance on both large numbers and small numbers with both total filled area and total contour length controlled. Results showed that infants succeeded in discriminating 4 from 8 elements, but failed to discriminate 2 from 4 elements, providing evidence for the existence of two…

In three experiments, 9-month-olds were given the opportunity to induce specific phonological patterns from manipulated syllable structure, consonant voicing position, and segmental position. Infants were then familiarized with fluent speech containing words that either fit or violated these patterns. Subsequent testing revealed that infants…

This study examined the associations between characteristics of mothers' narratives about their 7-month-olds, maternal depression, and their infants' affect regulation during the Still Face procedure. Findings showed that mothers' representations were linked with individual differences in infants' behavior, the association between mothers'…

Two studies examined whether object names and functions act as cues to categories for infants. Findings indicated that both 14- and 18-month-olds were more likely to select the category match after being shown a novel category exemplar with its function than when given no additional cues. Only at 18 months did naming the objects enhance…

Examined in two studies infants' reenactment of intended acts in failed-attempt paradigm. Found that when only first actions were counted, infants who observed the full-demonstration model produced more target acts. When all target acts produced within the response period were counted, infants in emulation-learning and spatial contiguity…

Examined consistency in behavioral state organization for 30 fetuses and neonates. Assessed heart rate pattern and presence or absence of eye and gross body movements during sleep, finding quiet sleep (QS), active sleep (AS), and indeterminate states in nearly identical proportions. Duration of enclosed QS epochs provided only stable measure of…
