Cooperation is necessary to solve many of our pressing challenges – including depletion of natural resources, managing the COVID-19 pandemic, and effective policy making. By studying the psychological processes underlying cooperation we gain knowledge that can help us create environments and institutions which will be more successful in tackling the societal challenges. The main goal of the course is to introduce students to the psychological processes of human cooperation. This course draws on theories and empirical findings from social, cognitive and developmental psychology, and behavioural economics.
The course will address questions such as:
● What are the evolutionary roots of human cooperation?
● How does prosocial behavior develop in children?
● What are the major strengths and weaknesses of human cooperation?
● Which factors support interpersonal and group cooperation?
● What is the role of communication and leadership in cooperative behaviors?
● How can our knowledge about game theory models improve decisions in public policy?
● How can we develop cooperation within organizations and in civil society?
