What are the neural mechanisms underlying social interactions? In this module, students will learn about neural mechanisms in primates underlying the detection and identification of living agents, the perception and decoding of the social signals these agents send, and the decisions about interacting with these agents. Brief insights into disorders of social interactions found in psychiatric conditions will then be discussed. These topics will be presented in the lectures, developed in the seminars and students will be able to get hands-on experience with designing and performing social perception and decision experiments in the practical course.
