Personality science examines human diversity in behaviours, thoughts, and emotions. A primary learning objective is for students to think scientifically about human diversity in personality traits. The course focuses primarily on empirical results that have accumulated since the 1970s. Students learn about the measurement of personality, biological and social causes of human diversity, and the influence of personality on major life outcomes. The course focuses on variation in personality that is normal, although the relationship between personality and health – both physical and mental – is examined.
