Chujun Lin, PhD

Postdoctoral Scholar in Psychology, Dartmouth College




I am currently a postdoctoral scholar in the Social Computation Representation And Prediction Laboratory (SCRAP Lab) at Dartmouth College, working with Prof Mark Allen Thornton. Before joining Dartmouth College, I worked with Prof Ralph Adolphs in the Emotion and Social Cognition Lab at the California Institute of Technology, where I earned my Ph.D. degree in social science in 2019. 

My research focuses on how people form impressions of others, in particular, impressions regarding others' relatively stable traits, such as personality. What are the psychological mechanisms (e.g., origins, dimensions, dynamics)? How do trait inferences interact with other psychological processes (e.g., understanding mental states, predicting actions)? What are the behavioral consequences in the real world (e.g., in politics, law, media)?


To answer these questions, I combine computational methods (predictive modeling, deep learning algorithms), social psychology (laboratory experiments, cross-cultural studies), and real-world metrics (e.g., political corruption records, social media popularity). I apply these methods to understand impressions of others formed from a wide range of stimuli, including text descriptions, face images, naturalistic videos, and face-to-face interactions. 

I am enthusiastic about open science. I have been pre-registering my studies, sharing experiment data and code on Open Science Framework.
