ABSTRACT
COVID-19 forced social interactions to move online. Yet researchers have little understanding of the mental health consequences of this shift. Given pandemic-related surges in emotional disorders and problematic drinking, it becomes imperative to understand the cognitive and affective processes involved in virtual interactions and the impact of alcohol in virtual social spaces. Participants (N=246) engaged in an online video call while their gaze behavior was tracked. Prior to the interaction, participants were randomly assigned to receive an alcoholic or control beverage. Participants' affect was repeatedly assessed. Results indicated that a proportionally larger amount of time spent gazing at oneself (vs. one's interaction partner) predicted significantly higher negative affect after the exchange. Further, alcohol independently increased self-directed attention, failing to demonstrate its typically potent social-affective enhancement in this virtual context. Results carry potential implications for understanding factors that increase risk for hazardous drinking and negative affect in our increasingly virtual world.
ABSTRACT
Many social interactions involve alcohol consumption, and drinking alcohol can lead to powerful increases in enjoyment in these social contexts. Yet we know almost nothing of the means by which alcohol enhances social experience. Importantly, since individuals in social contexts not only respond to environmental conditions, but can also actively generate these conditions, understanding alcohol's social enhancement within wholly unstructured social interaction presents challenges. To address this issue, the current study examines responses of individuals participating in a structured pleasurable experience in social context (humor presentation)-a drinking context with ecological-validity that permits us to test theories of alcohol-related social-enhancement through isolating responses to the controlled presentation of pleasurable stimuli (i.e., comedy punchlines). Participants (N = 513) were randomly-assigned to consume an alcoholic, placebo, or control beverage in the laboratory. Participants were video-recorded during presentation of a comedy routine in 3-person groups, and participants' Duchenne smiles were recorded on a frame-by-frame basis using the Facial Action Coding System. Comedy punchlines were coded by five raters and validated via an independently collected sample of participants (N = 30). Results of nested frailty survival models, controlling for the smiles of other group members, indicated a significant interaction between punchlines and alcohol in predicting smiles. Specifically, alcohol selectively increased smiling during times when no humorous stimuli were being presented, whereas there was no significant effect of alcohol on smiling in response to the humorous stimuli themselves. Findings highlight the importance of less intrinsically entertaining social moments for understanding alcohol-related social enhancement.
