Lecture Description

Why are people different from one another? This lecture addresses this question by reviewing the latest theories and research in psychology on two traits in particular: personality and intelligence. Students will hear about how these traits are measured, why they may differ across individuals and groups, and whether they are influenced at all by one's genes, parents or environment.

Course Description

What do your dreams mean? Do men and women differ in the nature and intensity of their sexual desires? Can apes learn sign language? Why can't we tickle ourselves? This course tries to answer these questions and many others, providing a comprehensive overview of the scientific study of thought and behavior. It explores topics such as perception, communication, learning, memory, decision-making, religion, persuasion, love, lust, hunger, art, fiction, and dreams. We will look at how these aspects of the mind develop in children, how they differ across people, how they are wired-up in the brain, and how they break down due to illness and injury.
