Curt Richter: psychobiology and the concept of instinct

Curt Richter is at the origins of psychobiology in the United States. For Richter the concept of instinct was central to his research. While he had diverse interests that traversed a great range of psychobiology, the concept of instinct was fundamental to his research on specific hungers and the regulation of the internal milieu. Debates about the concept of instinct would last the bulk of Richter's experimental career, culminating in an international conference a decade after the Second World War.
