In this article, the author synthesizes research from several disciplines to shed light on play's central role in healthy development. Gordon builds on research in attachment theory that correlates secure attachment in infancy with adult well-being to demonstrate how playfulness might be a lifelong outcome of secure attachment and a primary…

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

Evaluates the degree to which the social-referencing perspective provides a valid explanation of some features of infant behavior. (MP)

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)

Presents a developmental study of changes in infant attachment behaviors. Five groups of female infants, 8, 11, 14, 19, and 24 months of age, were observed during varying types of separation experiences. Changes in proximity behaviors and contact behaviors were analyzed. (BD)

Explores current theories of emotional development in order to identify the assumptions that could explain the strong antagonism toward early nonbasic emotions. Draws on the contrasting and polarity of viewpoints to examine the logical implications of these viewpoints for the very possibility of early nonbasic emotions and their reciprocal…

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…

Suggests that play begins with infant-adult interaction soon after birth rather than with much later peer interactions. Proposes a developmental sequence of infant play that reverses the sequences of the Howes peer play scale, and cites pertinent literature to support that proposal. (BC)

This set of checklists in separate English- and Spanish-language versions, is designed to help parents and childcare providers determine through observations a child's developmental progress from birth to age 5. The checklists are excerpted from the "Slow and Steady, Get Me Ready" guidebook, written by a retired kindergarten teacher with 25 years…

The Mental Development Scales: Birth to Three Years are instruments designed to assess developmental levels of young children within a setting familiar to the child. They (1) provide a greater understanding of child behavior and development, (2) serve as a basis for planning an individualized curriculum for each child, and (3) furnish the means…
