Wistar rats choose alcohol over social interaction in a discrete-choice model

G. Augier, V. Schwabl, et al.

This study reveals intriguing insights from Wistar rats, highlighting their overwhelming preference for alcohol over social interaction. Conducted by Gaëlle Augier, Veronika Schwabl, Asmae Lguensat, Mihai Atudorei, Osamudiamen Consoler lyere, Sandra Eriksson Solander, and Eric Augier, the research suggests that alcohol's unique reward interactions may challenge existing social choice models.

Abstract

Animal models of substance use disorders (SUDs) have faced criticism for their limited translational value. This study investigated the choice between alcohol and social interaction in Wistar rats, finding that rats almost exclusively preferred alcohol, regardless of partner type, interaction duration, housing conditions, or sex. Increased effort to obtain alcohol reduced its choice, but rats still preferred it even with significantly higher effort requirements. These results suggest the social choice model may not generalize to alcohol, potentially due to unique alcohol-social reward interactions not observed with sweet solutions.
