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…

Over the past 5 years the scientific study of adolescence has continued to grow in volume and sophistication. Drawing on recent articles published in the "Journal of Research on Adolescence", I take this opportunity to comment on some common understandings about the nature of adolescent development and behavior, recurrent tensions in the research,…

Defines life-span developmental psychology as the study of constancy and change in behavior throughout the life course. Advances metatheoretical view regarding development. Stresses focus on the dynamic and continuous interplay between growth (gain) and decline (loss). Examines structural contextual factors and study of range of plasticity in…

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

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…

Discusses processes in the development of shared pretend representations: adoption of shared pretend focus; metacommunication defining the activity as pretend play; and communication within pretend play. Examines claims that children's play becomes intersubjective only after three years of age. Concludes that intersubjectivity in peer pretend play…

Introduces this special journal issue by describing what developmental approaches are and how they can be applied to children with disabilities. Gives a short preview of the articles in the issue and raises future challenges for developmental research and intervention with young children with disabilities. (JS)

Examines the conceptual and empirical foundations of individual drug use stage development and progression related to tobacco, alcohol, and other drugs. Research examining interdrug use progression among youths supports the idea of a generally invariant sequence, involving nonuse to legal drug use, marijuana, and finally other illegal drug use.…

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)

Synthesizes literature on social comparison in young children. Findings center on (1) children's motivations to engage in social comparison; (2) peer targets; (3) age when social comparison appears; (4) developmental sequences; (5) effects upon subsequent behavior; and (6) sex-related differences. Suggests pratical implications for teaching.…

Reviews research on the early development of symbolic play. Suggests that symbolic play begins to emerge near the beginning of the child's second year and continues to play an important role in his or her development throughout the preschool years. Proposes basic techniques caregivers can use to facilitate and promote the development of symbolic…

Evidence for the construct validity of Washington University's Sentence Completion Test of Ego Development is reviewed. The test has adequate validity for research purposes but is neither valid nor reliable enough to be used as a clinical instrument without further confirming data. (BH)

In all of his published work, Jean Piaget never abandoned his original theoretical framework for the understanding of human development. This framework insists that intelligence is essentially a biological phenomenon; its development is best understood as the development of a sophisticated and highly successful adaptation device. This device…

An understanding of the stages involved in children's development of sensory motor integration would aid in the creation of instructional strategies in physical education. These strategies would optimize both the child's physical coordination and creative development by increasing the correlation between the demands of a learning environment and…
