Abstract

Objective: Despite increased attention to risks and benefits associated with moderate drinking lifestyles among aging adults, relatively few empirical studies focus on acute alcohol effects in older drinkers. Using electroencephalographic indices of early attention modulation (P1 and N1) and later stimulus processing (P3), we investigated whether acute alcohol consumption at socially relevant doses differentially influences neurocognitive performance in older, relative to younger, moderate drinkers. Method: Younger (25–35 years; n = 97) and older (55–70 years; n = 87) healthy drinkers were randomly assigned to receive one of three alcohol doses (placebo, .04 g/dl, or .065 g/dl target breath alcohol concentrations). Repeated-measures analysis of variance examined the effects of age, alcohol dose concentration, and their potential interaction on P1/P3 amplitudes and N1 latency during completion of a directed attend/ignore task. Results: Age-specific effects on P1.
