Abstract
Alcohol has been shown to have a variety of effects on cognitive performance in humans; the present study tested the effects of alcohol on visual selective attention using three different paradigms. The effects of alcohol intoxication over a broad range of blood alcohol concentrations (average between 0.01 and 0.08) were evaluated for change blindness, inattentional blindness, and multiple object tracking. Alcohol was found to impair inattentional blindness performance, negatively affecting participants’ ability to notice the unexpected changes presented. This result is interpreted as support for the alcohol myopia theory. No significant effects of alcohol were found for change blindness or multiple object tracking.
