Direct (systematic) observation has been a mainstay of my research for over three decades. I believe it is an important tool for assessing physical activity, because it can simultaneously provide contextually rich data on the setting in which the activity occurs. It is particularly useful for those interested in using ecological and…

Progressive developments in scanning technologies over the last decade have led to a surge of new research into the structure and function of the brain and into differences between the brains of teenagers and other adults. This work has not been free of controversy, notably around the question of deficits in the capacity of young people concerning…

Adolescence is a developmental period that entails substantial changes in affective and incentive-seeking behavior relative to both childhood and adulthood, including a heightened propensity to engage in risky behaviors and experience persistent negative and labile mood states.

Thirty-six matched family triads, half with sons hospitalized for a schizophrenic…

Presents a case study of an elementary school child with a learning disability to illustrate that both performance and disability have to be understood in terms of the social environments with which they are linked. (FL)

Research findings and theories regarding adolescent contraceptive use are reviewed to propose an alternative framework relying on social learning theory. Environmental context, cognitive influences, and behavior execution constraints are suggested as the foundation for contraceptive behaviors. The behavioral skills teenagers need to use birth…

We examined the relationship between parents' behaviour and children's use of simple arithmetic strategies while playing a board game in contrast to solving arithmetic problems. In a microgenetic study spanning 3 weeks, 5-year-old children who were just beginning kindergarten played a modified game of "Chutes and Ladders" with one of…

This monograph presents the proceedings of a workshop on the contexts of social drinking, i.e., the situational factors associated with drinking which might increase or inhibit heavier consumption.

A "mindy" is a unit process of mind constructed through using a mental shape as a sketch for mindy processing. A social…
