Abstract
Alcohol has complex and multifarious effects on cognition. One means by which alcohol can influence a wide variety of cognitive behaviors is through its effects on attention. This study investigated the effects of alcohol consumption on sustained attention, or vigilance. We report here a high-powered study in which participants consumed either an alcoholic or a non-alcoholic beverage and then completed a spatial vigilance task, with half of the subjects in each condition receiving two rest breaks interleaved throughout the task. Alcohol impaired vigilance performance and also decreased the local recuperative benefit of rest breaks. Difference in decision processes were apparent, with intoxicated participants employing a more liberal and less optimal response criterion. These findings underscore the detrimental effects of alcohol on attention and provide novel evidence that rest is less effective following alcohol consumption.
期刊介绍：
The journal Attention, Perception, & Psychophysics is an official journal of the Psychonomic Society. It spans all areas of research in sensory processes, perception, attention, and psychophysics. Most articles published are reports of experimental work; the journal also presents theoretical, integrative, and evaluative reviews. Commentary on issues of importance to researchers appears in a special section of the journal. Founded in 1966 as Perception & Psychophysics, the journal assumed its present name in 2009.
