ABSTRACT
The central argument of this article is that human development should be viewed as the product of the interpenetration 1 of cultural and biological processes. Using developmental system theory, it is argued that our work as investigators of human development is to examine this mutual coregulation: how biology and culture interpenetrate over time in concert with developmental processes. Various findings from developmental research are used to provide evidence on (a) how our biology constrains, gives expression to, mediates, or moderates how culture operates on developmental processes and (b) how culture infiltrates and becomes part of our biology and basic developmental processes. Examples of advances in neuroscience are also used to illustrate this interpenetration and to argue for the pervasiveness of cultural influences on development. To conduct the necessary research, new methodologies are needed. Promise is seen in emerging areas of social cognitive neuroscience.
