Tarja Raag, Associate Professor of Psychology120px-Gay_flag.svg

I received my B.A. in Psychology from Skidmore College in 1986, and my Ph.D. in Experimental Psychology (Major area of study in Developmental Psychology) from Indiana University in Bloomington, Indiana in 1992. I served as a Post Doctorate Student at the University of Miami, Florida for 2 years, following which I was a faculty member at Kenyon College from 1993 to 1995. I joined the faculty at Colby College in the fall of 1995 and have been here ever since. My regular teaching load includes the Developmental and Intelligence sections of our team-taught Introductory Psychology (PS111) course as well as Child Development (PS255), Adolescent and Adult Development (PS256), Psychology of Sex and Gender (PS352), and Developmental Seminar (PS335).

My research interests are in areas relevant to social development, with special interest in emerging adult identity (including racial/ethnic identity) and well-being in college populations (with specific focus on acceptance of life events, positive and negative). I also value applied work and civic engagement in my teaching and support students’ engagement in the important work done by our local Hospice and Family Violence Project nonprofit organizations. I would welcome chances to talk about research and community activism. You may contact me at: traag@colby.edu or (207) 859-5558.
