Conscious awareness is a prized possession of mankind. Lay people and philosophers alike ascribe sacred values to people’s capacity for conscious thoughts, reasoning, and behaviour. However, social psychology research demonstrates the powerful influence of the unconscious, mechanisms that occur without conscious awareness, on high-level mental processes. In this module, students will be exposed to an array of research revealing how the unconscious affects social perception, social behaviour, goal pursuit, and complexed decision making. Students will acquire a basic understanding of how the unconscious operates and appreciate the real-life implication of the unconscious in consumer behaviour, public opinion, and legal decisions.
