Investigated the possibility that previous reports of a relation between locomotor status and stage-4 object permanence performance could be generalized to performance on an object localization task. Findings suggest that the effects of locomotor experience on infants' search performance are quite specific and mediated by a variety of factors that…

In this study of the visual placing response (an extension of the paws or arms on approach to a visual surface), infants extended their arms almost as much to a gray surface as to a patterned one. (Author/CS)

Sixteen white home-reared babies (eight boys - eight girls) ranging in age from six months to two years were studied during home visits. Piaget's sensory-motor development theory of imitation was employed, and his special thesis of the hierarchical sequence was tested. The examiner proposed four critieria for assessing the development of imitation…

Multipurpose demonstrations of child development are easy to produce by videotaping children while they interact with parents, siblings, or friends. Unlike commercial films, videotapes without narration allow students to formulate and test their own research questions. This article describes how to use unedited videotapes for laboratories in…

Takes an exploratory look at the relationships between (1) the various fears that develop during infancy, (2) perceptual-cognitive development and the exhibition of specific fears, and (3) individual differences in temperament and the manifestation of specific fears. This paper was presented at the Merrill-Palmer Institute Conference on Research…

Three children were observed in their homes approximately once a month for one year, from their 11th through 22nd month of life. Based on observation of the children's changing nonverbal behaviors, a five-level developmental sequence documenting the evolution of the cognitive notion of agent was developed. (Author)

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. Journal Availability: American Academy of Pediatrics, P.O. Box 1034, Evanston, IL 60204…

When children enter school, their principal way of thinking is through talking aloud (rather than through internal verbalization), and they need to be encouraged in their use of language as they confront new academic problems. (JD)

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…

Discusses important recent strides in the documentation and understanding of the infant's learning and memory capacity. Focuses on the psychobiology of learning, hedonic mediation of approach-avoidance and learned behavior, infant memory, and critical conditions of infancy and behavioral misadventures. (RJC)

Discusses general developmental principles which have emerged from studies in motor development. (RJC)

Two groups of infants were studied to demonstrate that changes in reaching are determined by the interaction of organismic and environmental constraints. The infants were placed in three different positions and observed for quantity and quality of reaching. Results indicated that both environmental constraints and growth contribute to reaching in…

Notes that early infancy, rather than being a period of helplessness, is a period of active exploration and reciprocal interaction with caregivers. Includes activities caregivers can engage in with infants to stimulate infant sensory abilities. (HTH)

Both versions of the Bayley Scales of Infant Development were administered to 32 children, ages 3- to 28-months. Significant differences were noted between scores. Children below 12 months of age displayed larger discrepancies than the older children. Information is important for children evaluated longitudinally since they likely will score lower…
