Why are so many people?even those whose basic physical needs are met?still challenged to eat adequately, exercise, and sleep enough? We will consider how human willpower tendencies interact with social, cultural, and physical contexts to support (or thwart) health promoting activities. Based on a close reading of current psychological science and related areas of inquiry, students will design and assess an intervention to improve their individual health, and in groups, identify and implement a project focused on campus-level health promotion. Emphasis will be on critically evaluating and applying primary empirical articles. Prerequisites: PSY 100 and 202. Recommended: PSY 140.
