This course will present social behavior from an evolutionary and neurobiological perspective. We will survey the many properties of animal social behavior that are now known to be shared by humans and other primates including aggression, dominance, attachment, grief, sympathy, helpfulness, altruism, friendliness, peacemaking, maternal care. The apparent evolutionary history as well as the descriptive characteristics of each social tendency will be studied using data from both field observations and laboratory experiments as available. In those cases where data are available, the course will also present what is known about the neural mechanisms that govern the social behaviors. Note: Check class schedule for semesters offered.
