Socioeconomic Status Shapes Dyadic Interactions: Examining Behavioral and Physiologic Responses.

Abstract

With more opportunities for diverse interactions, little is known about how social interactions involving people of different socioeconomic status (SES) may unfold. We investigated social-attunement patterns in dyadic interactions involving SES. Unacquainted adults recruited from a community in the United States interacted with similar-or-different-SES partners in the lab (N = 130 dyads). Attunement was assessed throughout the interaction by examining physiological linkage-how much a person's physiological change is predicted by another's physiological change over time. Overall, low-SES participants showed stronger physiological linkage-indicating greater attunement-to partners across SES. Participants also appeared more comfortable when interacting with low-SES partners. There were no SES differences in dominance during the conversation. After the interaction, participants reported liking similar-SES partners more than different-SES partners. These patterns suggest that during interactions, lower-SES individuals are more other-focused than high-SES individuals, and in-group preference prevails. We note limitations in the racial representation of our sample.
