This seminar will explore how the cultural environment influences, and is influenced by, reasoning and other psychological processes. The cognitive revolution has been based upon the tacit assumption that all humans have the same basic cognitive structures and functions, and that cultures and other social contexts contribute only peripherally important content differences. Anthropologists have long argued that both the content and function of knowledge may be strongly linked to the types of problems that a given culture or social group must habitually solve. The seminar will focus on ways in which cognition may be culturally mediated, socially situated, and contingent on historical forces.
