Social Influences on Risky Choices in Cocaine Use Disorder

Abstract

Peer influences likely contribute to substance use and misuse (Hayes et al., 2006; Ouimette et al., 1997; Pfeifer et al., 2011; Simoni et al., 2007). However, mechanisms via which social others affect decision-making have received limited investigation in substance using individuals. We combine functional neuroimaging and a model-based behavioral economics approach to examine how individuals with cocaine use disorder (CUD) process and use social influence when making decisions about risky options.
