The development of adaptive competence: Why cultural psychology is necessary and not just nice

I argue that developmental psychologists need to view cultural approaches to cognitive development as necessary and not just nice. Cultural psychology enables one to study problems one otherwise might not be able to study and also to identify solutions to problems that might be obscured or even distorted if one looked only at results within a single culture (usually, one's own). I describe work my colleagues and I have done around the world addressing specific problems such as what does it mean to be adaptively intelligent in various cultures, how does illness affect intellectual functioning, and what do people even mean by “intelligence” in different cultures. The results show that cognitive development can be fully understood only if one looks beyond one's own cultural boundaries and preconceptions. The article further argues that a theory of successful intelligence can be a useful way of studying phenomena of intellectual development within a cultural framework.
