Chujun Lin, PhD

Postdoctoral Scholar in Psychology, Dartmouth College

Welcome!

I am currently a postdoctoral scholar in the Social Computation Representation And Prediction Laboratory (SCRAP Lab) at Dartmouth College, working with Professor Mark Allen Thornton. 

My research focuses on how people form impressions about others, in particular impressions regarding others' relatively stable traits. What are the psychological mechanisms (e.g., origin, dimensions, dynamics)? How does it interact with other psychological processes (e.g., inferring others' mental states, predicting actions)? What are the behavioral consequences in the real-world? I study these questions using a variety of stimuli (e.g., stories, faces, movies) and a combination of behavioral and machine learning methods.

​

I am enthusiastic about open science. I have been pre-registering my studies, sharing experiment data and codes since my second research project; recently started trying out registered reports. 

​

Before joining Dartmouth College, I worked with Prof Ralph Adolphs in the Emotion and Social Cognition Lab at California Institute of Technology, where I earned my Ph.D. degree in social science in 2019.
