Molenaar's (2015) article concerns Developmental Systems Theory (DST) in relation to behavior genetics and he presents implications of DST for empirical research, especially the need for subject-specific studies. In this commentary, the article is discussed from a broader developmental science perspective, particularly regarded through the lens of…

What we're thinking about behaviorally challenging students and what we're doing to them requires a fresh look. When schools believe that parental discipline explains a child's misbehavior, educators are less likely to consider different explanations for the misbehavior and the full range of interventions that could be implemented at school. And…

The cognition/conduct problem is outlined as it arises in cognitive-developmental moral theory. A model of the connection between stage of moral reasoning and behavior is developed, involving two separate steps (from reasoning to judgments and from judgments to behavior).(Author/RH)

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…

This approach is primarily concerned with social reasoning and judgment, with how children reason about social phenomena, not just what they reason. The how of social reasoning is called structure, what is reasoned about, content. Presented at the American Psychological Association, Chicago, 1975. (Author)

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…

Seventeen processes in the development of expressive behavior are reviewed and coordinated in a framework that is shown to accommodate current perspectives on expressive behavior development. Works of Ekman, Izard, Lewis and Michalson, and Sroufe are briefly reviewed. Neglected areas of research are indicated and the course of expressive behavior…

For the individual, gender difference falls along the feminine-masculine continuum with strong neurodevelopmental influences at various points throughout the lifespan. Neurodevelopmental influences are conceptualized in a vector model of sex difference. Vector attributes, direction and magnitude, are influenced initially by differences in levels…
