Abstract
Facial expressions are critical for communicating pain interpersonally. Using eye-tracking, pupils dilated in a pain recognition task (p=0.002) as well as a pain intensity task (p<0.001) when perceiving painful facial expressions. This supports the literature that neural systems of pain experience in oneself overlap with perceptions of pain in others.
