This course covers reasoning, decision making, and behav- ioral game theory, which are major domains in human higher order cognition. For each topic, we start from nor- mative theories, go through formal and mathematical models, and introduce empirical studies. The course emphasizes integrations of competing approaches within a domain, integration between reasoning and decision mak- ing, and integration between individual decision making and game-theoretic interactions. Each year, the course has a theme. The theme for this year is quantum cognition, which applies quantum theory in cognitive modeling. This course is designed as self-contained, and no pre-require- ments. A middle term presentation and a final term paper are required for each student. Graduate students only. Fall term annually. 4 credit hours
