The Evolution and Development of Social Cognition

Cognition is a biological function, not a cultural invention. Our nervous systems detect, encode, and process information not because someone invented these capacities in antiquity, but because evolutionary forces shaped the organs that instantiate these biological functions.  Cognition is the function that ensures a non-arbitrary relation between perception and action.  Historically, psychologists have tended to overlook or downplay the role of biology and evolution when developing theories of cognitive functions, with the inevitable result that our theories have often provided inadequate predictions and explanations of cognitive phenomena. This talk will focus on cognition that is highly canalized as a result of learning biases that evolved to cope with the exigencies of the social environment. These highly specialized functions need not be present at birth. Instead, the balance of comparative, developmental, and neuroscientific evidence weighs in on the side of fast-track learning through early emerging biases that entrain the focus of our attention on the environmental stimuli and contingencies that are most vital for survival in a complex social environment, while neurological plasticity allows our actual environmental experiences the final say in whether and how those predispositions are expressed.
