Reports a semilongitudinal study which measured the respiratory activity during crying of 10 normal infants aged two days to eight months. (BD/BR)

Comments on Thelen and Ulrich's monograph in this issue. Examines theoretical and empirical sections and findings, concluding that the authors have taken a major step forward by introducing the dynamic systems perspective to the study of behavioral coordination in infants, thus opening the way for experimental investigation of phenomena that could…

The purpose of this study was to longitudinally examine the development of anticipatory visual search and to find out the effects of preceding experiences upon the search during the second year of life. The sample consisted of 18 Japanese firstborn nonretarded children from middle-class families who were individually tested at 11, 12, 14, 16, 22,…

To document movement patterns and to examine developmental interrelationships, the ontogeny of rooting, lip, lateral tongue, mouth opening, biting, and Babkin reflexes and the development of emerging chewing behaviors were observed in two normal infants over a period from 1 week to 35 weeks of age. (Author/RH)

Studied 112 preterm infants to determine developmental changes and stability of individual differences. Results indicate significant developmental gains with age, and highly significant individual stability of performance across age. (RJC)

Longitudinal data concerning fear responses in 30 boys and 30 girls observed from ages one month to 8 1/2 years suggest that in males--but not in females--a predisposition to a particular level of fearfulness is set by events that occurred before 6 months of age. (Author/MG)

Studied the ontogeny of walking by prelocomotor infants. Results support a dynamic systems view of development and the view that upright locomotion emerges from the self-organization of multiple cooperating elements rather than as a result of a preexisting neural code. (Author/GR)

This interim report is part of a longitudinal study of developmental behavior designed to determine whether infants from culturally disadvantaged homes have different developmental patterns than infants from advantaged homes. Twenty six culturally disadvantaged infants were individually evaluated on the Bayley Scale of Infant Mental and Motor…

Many studies using questionnaires and observational methods to collect information on the pointing gesture in infants have recently been performed. However, no study based on long-term observation is presently available that deals with the appearance and development of pointing as an interaction between mothers and their children. Therefore, this…

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…

Reports on development of a model for studying communicative competencies using naturalistic observations of specific behaviors. Discussion focuses on ways mothers and toddlers train each other to be successively more effective in their relationships. (ED)

This paper is designed as an information guide for those persons responsible for rearing human infants from birth to 18 months. The author provides an extensive review of the literature and trends of research in this area noting that the current volumes of knowledge in this area are not yet dependable enough to provide reliable bases for practice.…

Examined the concordance between mother-infant attachment behavior and patterns of mother-child reunion responses when the children were age six. Found that concordance between four types of attachment status was 82%. Also found a correlation between children's observed social competence at age five and their reunion patterns at age six. (MDM)
