Participants performed an orientation discrimination task, reporting the tilt of a peripheral Gabor patch target. Valid, neutral, or invalid precues—central (endogenous) or peripheral (exogenous)—were presented to manipulate attention. Perceptual sensitivity was compared between alcohol-free and alcohol-intake conditions. Results revealed that alcohol spared endogenous attention’s ability to enhance sensitivity at cued locations and reduce interference at invalidly cued locations. In contrast, exogenous attention’s facilitatory effects at cued positions were impaired, while its effects at uncued locations remained intact. This dissociation indicates that endogenous and exogenous attention rely on distinct neural mechanisms, with alcohol selectively disrupting exogenous orienting.
