Welcome to the homepage of the Colby Personality Lab, directed by Chris Soto. The CPL conducts research examining three key issues. The first is personality structure: how people’s specific thoughts, feelings, and behaviors cohere into broader personality traits that persist over time and across relevant situations. I am especially interested in questions about whether, how, and why people’s personalities might be organized differently at different times of life, or in different social contexts. For example, are personality traits organized in similar or different ways during childhood versus adulthood?

The second issue is lifespan personality development: when, how, and why people’s personalities change as they age. I am curious both about how people’s personalities typically change across the life span (normative change) and about why different people’s personalities change in different ways (individual differences in change).

The third issue is personality and life outcomes: how someone’s personality helps shape the course of their life. I am particularly interested in understanding how personality characteristics influence (a) subjective well-being (i.e., how happy or unhappy someone is with their life), and (b) political attitudes.

I took a personality test for the first time as a junior in high school, and have been hooked on personality psychology ever since. I received my A.B. in Psychology from Harvard University and my Ph.D. in Social and Personality Psychology from the University of California, Berkeley. Since arriving at Colby in 2009, I’ve enjoyed teaching courses about personality psychology, research methods, and statistics, working with motivated young researchers, and exploring Maine.

I’m a sophomore from Lake Forest, Illinois majoring in psychology and mathematical sciences. I am interested in personality development and how we are able to effectively measure certain personality traits. I’m also very intrigued by how these particular traits are linked to psychiatric disorders. The brain and its role in governing personality fascinate me as well. In addition, I’m curious as to how life experiences can shape personality, and I would like to learn more about how personality changes as we age.

I’m a senior from Hong Kong, majoring in Psychology, minoring in Film Studies and currently on the Pred-Health path. I am interested in child development, especially concerning topics such as developmental issues in children with long-term diseases who are required to stay in the hospital for an extended period of time. I would like to study different ways that help in developing personality in such children, such as communication between hospital personnel and patients, hospital schools, medical clowns and animal doctors.  I would like to learn about how personality develops over time, and various factors that mold a child’s personality, especially children with speech deficiency and autism.
