Christopher Soto

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.

Note: For information about using the Big Five Inventory-2 in scientific research, see the BFI-2 tab of this webpage. If you’d like to take an online version of the BFI-2, you can do so at my personality test website.

Christopher J. Soto

Christopher SotoI 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.

 

Student Research Assistants

Christa Ouellette ’22

Christa OuelletteI am a senior from Lamoine, Maine (which is about 30 minutes from Acadia National Park), majoring in Psychology with a concentration in Neuroscience. I have also taken many courses in the Music and Theater Departments, which has helped me to establish connections between psychology and art, specifically the ways in which we respond to music and color. On campus, I work in the Biology Department office, and I am a part of the Colby Jazz Band, the Colby Megalomaniacs, and the Colby Music Incubator. In my free time, I like to draw portraits and spend time outside, especially in the spring and summer.

The Big Five Inventory–2 (BFI-2)

The BFI-2 is a measure of the Big Five personality domains (which we label Extraversion, Agreeableness, Conscientiousness, Negative Emotionality, and Open-Mindedness) and 15 more-specific facet traits. A self-report form, scoring key, and list of items are available below. The BFI-2 items are copyright 2015 by Oliver P. John and Christopher J. Soto. Permission is granted for personal and research use of the BFI-2.

Note: If you’d like to take an online version of the BFI-2, you can do so at my personality test website.

Short and Extra-Short Forms of the BFI-2

The BFI-2-S is a 30-item short form, and the BFI-2-XS is a 15-item extra-short form, of the BFI-2. They are appropriate for research contexts in which, due to pressing concerns about assessment time or respondent fatigue, administering the full BFI-2 would not be feasible. For most studies, however, we recommend administering the full measure due to its greater reliability and validity.
