An essential component of social health is the ability to appropriately value and respond to socially rewarding stimuli. Heavy alcohol users (HAU) are vulnerable to the effects of their social environment; HAU commonly exhibit detrimental social behaviors, and social triggers can provoke problematic use (escape). Additionally, HAU can experience alterations in the neural networks responsible for responding to and evaluating non-social rewards, but it is unknown how HAU affects the networks underlying social reward.
