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 College 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 am a junior from Bethesda, Maryland, majoring in Psychology and Economics. I am interested in the brain and how it governs personality and behavior. I am also curious about how nature and nurture work together to influence someone’s personality, especially the amount of influence one’s environment and experiences hold over a person’s brain and personality.
I am a sophomore from Fresno, California, currently planning to major in biology with a concentration in cell and molecular biology. I am interested in how the brain and personality develop in children, especially during puberty, as well as how physical and chemical changes in the brain may affect personality exhibition in elderly people. I am also interested in how certain milestones in life, especially marriage, affect personality immediately after the milestone’s occurrence as well as several years or decades later.

The Big Five Inventory–2 (BFI-2)
The BFI-2 is a measure of the Big Five personality domains (Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness to Experience) and 15 more-specific facet traits. A self-report form, scoring key, and list of items are available below.
