In mammalian species, behavior begins in utero, hidden within the mother's body. This biological fact has made it difficult to observe or to access fetuses, leaving the beginnings of behavior to the imagination or allowing it to be forgotten or ignored. Such truncation of perspective probably helped many to consider behavioral capabilities first…

Provides an introduction to a special section on developmental behavioral genetics (the study of genetic and environmental influences on individual differences in behavioral development), discussing the potentialities of the interdiscipline and presenting an overview of the following articles. (Author/RH)

Examines the impact of Arnold L. Gesell on developmental psychology. Gesell is best remembered for his developmental norms, acquired from observations of infants and children. Gesell's ideas about maturation have lost favor, but his belief in infants' native abilities is still a dominant theme in theories. (BC)

Argues that the world view of contemporary behavior analysis, especially behavior analysis of child development, is contextualistic, not mechanistic. The history of behavior analysis is presented in a revised account that focuses on philosophic movements. Contextualism of behavior analysis is contrasted with mechanism with respect to five core…

Considers areas of consensus from commentaries, including the value of an evolutionary perspective and the utility of exploring variations in physical activity play. Examines areas of debate, including the nonplay-play distinction, functions of rough-and-tumble play, and the opportunities of juveniles for exercise training. Calls for more directed…

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…

Through examples of both a child's imagination and pretend play activities, demonstrates how a child's imagination is the thinking function that sets the stage for play, while actual play consists of a child's understanding and representation of reality. (HOD)

This article proposes that intuitive behaviors may be used to detect and resolve potential conflict in mother-infant relationships. Previewing, in which the caregiver introduces the infant to the physical sensations and interpersonal meaning of a new developmental skill, is suggested as a way of moving the mother-infant relationship in the…

Resilience is the ability to thrive, mature, and increase competence in the face of adverse circumstances. Recent research has uncovered personal and environmental characteristics that contribute to resilience during infancy and toddlerhood, as well as characteristics that predict resilience in later years. Resilient infants and toddlers are…

Maintains that the "getting into shape" hypothesis of explaining the inverted-U distribution of exercise play across age is likely incorrect. Argues that the biological study of human physical activity play, as recommended by Pellegrini and Smith (1998), will reveal whether physical activity play represents an example of…

The intense striving for power which characterizes much of male behavior occurs inevitably as part of the process of gender acquisition and consequently contributes to a sense of psychological vulnerability in the male personality. Masculine and feminine attributes develop spontaneously from young children's tendencies to compare themselves to…

This article presents some of the changing views influencing psychologists, physicians, and other persons interested in preventing developmental difficulties and promoting physical and mental health in children. (DB)

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)

Responses to youth violence include intervention programs to teach children alternative skills for solving problems and to challenge superficial beliefs about the glories of violence. Children on a destructive path need someone they can trust who will guide them. Lists 29 measures in response to school violence and the percentage of school…

Extending the work of behavioral scientist Urie Bronfenbrenner on the social and contextual factors influencing human development, this collection of essays, from scholars in a range of disciplines, shows how Bronfenbrenner's ecological theory and research have transformed the way many social and behavioral scientists approach, think about, and…
