The effects of obstetrical medication on neonatal behavior were studied using a sample of 64 Israeli infants from medicated and non-medicated mothers. Most medicated mothers received a base dose of 75 mg. of Meperidine plus a base dose of 25 mg. of Phenergan. Other drugs used included Demerol, Valium, Butalgan, Pitocin, Pantopon, Trilene, Naline,…

In this study, free play with toys having unambiguous functions was examined to test the hypothesis that a basic cognitive metamorphosis is associated with the new competences displayed in children at about 12 months. Functional play was observed in 64 children at 9 1/2, 11 1/2, 13 1/2, and 15 1/2 months of age. Six sets of toys with 36…

This study examined behavioral correlates of the rapid central nervous system changes occurring in the first 4 months of life. It was hypothesized that during the early months of infancy, visual preference would occur as a function of quantitative dimensions of the stimuli (size) which could be mediated at a subcortical level. It was further…

This paper briefly reviews studies of infant-peer and infant-mother interaction, and describes a study which compares the effects of mothers and peers on toddler play. Twenty-six toddlers (13 males and 13 females) aged 21 to 24 months were observed in two social situations each: playing with his/her mother, and playing with a familiar peer (after…

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)
