In this study, two similar depth perception experiments were conducted to investigate 3-month-old infants' perception of changes in depth while they were being moved. In the first, the subjects, 18 infants (80 to 105 days old) were lowered face down towards the textured floor of a 3-sided enclosure (visual crib). Three experimental conditions were…

Research (1972-74) concerning infant care and development is surveyed, supplementing an earlier review of literature on the same subject. The literature search was performed to provide materials which could contribute to the improvement of services to school-age parents with infants. Studies dealing with infant development (e.g., nutrition, early…

The purpose of this paper is to demonstrate that specific spatial and possibly temporal rates of change dominate early infants' looking, that these spatial and temporal events have meaningful and specific empirical correlates in neurophysiology as a function of age, and finally that neurophysiologically constrained models provide testable…

This report describes the development and testing of a screening method designed to describe the Cornell Infant Nursery environment and infant activities in quantitative terms. The scanning procedure developed is basically a time-sampling way of collecting data on the normal operation of the nursery. Two long lists of variables (categories of…

This study explored the relationship between the mother-infant interaction and the concurrent perceptual-cognitive and intellectual status of the infant. One hundred and eight-nine 12-week-old infants were given a battery of perceptual-cognitive tasks, including the Mental Developmental Index (MDI) of the Bayley Scales, the Corman-Escalona Scales…

Attempts to determine whether infants' performance in two search tasks is related to their entry into Stage 6 of object permanence development (thereby testing Piaget's claim that only Stage 6 infants possess the capacity for representation). (BD)

Examines the early development of low birthweight infants and its relationship to five categories of medical and environmental variables: (1) health; (2) family status; (3) family context; (4) family process; and (5) parenting. Results indicated that scores on the Bayley Mental Development Index at 18 months were related to all five categories of…

Study looks at pigtailed macaque in the context of visual recognition problems adapted from a standardized test developed for use with human infants. Results demonstrate that the low-risk group easily differentiated novel from previously seen targets; the high-risk group gave no evidence of recognition. (Author/RWB)

Adopts a longitudinal design to track mother-child developmental change in infant task-related mastery and concomitant maternal behavior. Finds that, as infants gain more mastery across time, mothers gradually withdraw support in terms of concrete, specific and nonverbal means of instruction. Results support a one-step-ahead model for maternal…

Examines qualitative information from 15 mothers whose childen had died several years earlier from Sudden Infant Death Syndrome. Concludes that mothers who experience a muted but comfortable dynamic intrapsychic relationship to the memories and thoughts associated with their children have achieved resolution of the loss. (NRB)

Studied across a 16-month period, young children of deaf parents showed accelerated early language development, on the average producing their first recognizable sign at 8.5 months, their tenth sign at 13.2 months, and their first sign combination at 17.0 months. Findings are inconsistent with previously reported patterns of synchrony between…

Examined the relationship between responsiveness to auditory novelty in full-term and preterm infants and subsequent intellectual performance at five years of age. Results suggest that measures of early perceptual-memory development may reflect early cognitive processes necessary for later intellectual performance. (Author/RH)

Distributed by the U.S. Departments of Agriculture, Education, and Health and Human Services, this pamphlet provides parents with information and advice about their infants in the tenth month of life. Following a brief description of developmental characteristics at this age, the pamphlet offers advice on a variety of topics, including: guarding…

This paper presents the results of a comparative analysis between full term typical infants and those born micropremature in the developmental construct of mastery motivation. The sample consisted of 10 micropremature infants with developmental levels within the normal limits and 10 full term 9- to 12-month-olds (adjusted for prematurity) matched…
