Lisi, M. P., Giometti, A., Fusaro, M., & Aglioti, S. M. (2026). Surrogate bias: Behavioral and physiological effects of seeing ingroup and outgroup virtual agents touching one’s embodied avatar. Computers in Human Behavior Reports, 101273.
🥽 In our new study published in Computers in Human Behavior Reports, we used immersive virtual reality to investigate how group membership and individual differences shape responses to social touch.
🧐Across two experiments with heterosexual Caucasian participants (48 men and 48 women), participants observed Caucasian or African, male or female virtual agents touching intimate, neutral, and social areas of their gender-matched embodied avatar. 📏We measured subjective ratings, skin conductance, heart rate, and interpersonal distance.
🔎In men, outgroup male touch to intimate and social areas elicited stronger skin conductance responses. In women, implicit racial bias indirectly reduced the pleasantness of outgroup touch through its effect on perceived attractiveness. More broadly, touch evaluations were also shaped by attractiveness, intergroup disgust, ideological attitudes, and interpersonal distance.
🧠Overall, the findings show how IVR combined with psychophysiology can reveal both explicit and implicit components of intergroup social interaction.
