Henderson, Thomas C.; Cohen, Elaine | Innate theories as a basis for autonomous mental development | Sloman (in robotics), Chomsky and Pinker (in natural language), and others, e.g., Rosenberg (in human cooperative behavior) have proposed that some abstract theories relevant to cognitive activity are encoded genetically in humans.
