Attentional and Neural Processing of Affective and Alcohol-Related Images in University-Attending Emerging Adults.

ABSTRACT

High-risk drinking is prevalent in university-attending emerging adults. This coincides with a critical time for the development of higher level cognitive and emotional processing and underlying neurobiological mechanisms. Cognitive and emotional processing seems to have a particularly sensitive relationship with alcohol. The current study sought to examine the relationship between alcohol use and neurophysiology in an emerging adult, university-attending population. Neurophysiological response, defined as event-related potentials, to alcohol-related and emotionally affective images were evaluated in 23 drinkers and 21 nondrinkers. Drinkers had a greater attentional response to alcohol, positive, and negative images compared to nondrinkers. No differences were found between groups for attentional response (P2) to neutral images or for later emotional processing (late positive potential) for any stimuli type. These data suggest that this drinking population processes alcohol stimuli and affective images similarly and more robustly than nondrinking peers. These data support a relationship between alcohol and emotional processing in emerging adults.
