Argues that dynamic systems approaches may provide an explanatory framework based on general scientific principles for developmental psychology, using principles of self-organization to explain how novel forms emerge without predetermination and become increasingly complex with development. Contends that self-organization provides a single…

When pioneering longitudinal studies of child development extended into adulthood, they generated issues that could not be addressed satisfactorily by available theories, including the recognition that individual lives are influenced by their ever-changing historical context and that human development concepts should apply to processes across the…

Maintains that advances in the literature on perception-action development suggests that tool use may be a more continuous developmental achievement than previously believed. Suggests new research directions, including efforts to investigate the processes by which children detect and relate affordances between objects, coordinate spatial frames of…

Considers the nature and developmental functions of physical activity play. Distinguishes three kinds of physical activity play with consecutive age peaks: rhythmic stereotypies, exercise play, and rough-and-tumble play. Considers gender differences and function in terms of immediate and deferred consequences in physical, cognitive, and social…

Argues that the operating characteristics of perceiving and remembering provide a foundation for progress on detailing the processes through which knowledge is realized in real-time tasks and in detailing the processes of developmental change. Includes three examples to illustrate how forming developmental hypotheses in terms of perceiving and…

Presented are a literature review and new data on correlates of newborn auditory brainstem evoked responses (ABRs). Concludes that disorders of the central components of the ABR may be more of prenatal than of postnatal origin. The I-V interval had low but reliable correlations with four of 11 Brazelton scale variables. (RH)

Calls for a process-oriented approach to study of categorization in infancy. Maintains that further understanding of infant categorization and its changes with development requires a more direct assessment of infants' category formation. Argues that two research directions will enhance understanding of categorization: (1) contextual variations on…

Reviews research on the determinants and the effects of parents' attributions. The evidence suggests that parents do form attributions for their children's behavior; these attributions vary in predictable ways across judges (mothers versus fathers), targets (age or sex of child), and behavior outcomes (positive or negative); and attributions…

Discusses how social trends changed father involvement and family life, and in turn affected children's and fathers' developmental trajectories. Examines how today's children will construct expectations about fathers' and mothers' roles. Maintains that a life-span approach considers the broader sociohistorical context in which fatherhood develops.…
