The issue of alcohol use and abuse among older adults is one that is gaining attention in current literature. Although it is an important issue, empirical evidence within the domain of alcohol, aging, and cognition, is sparse. Thus, the proposed preliminary study was designed to examine the relationship between chronic alcohol consumption and information processing speed in older adults. Eight matched participants (4 per group, mean age 56 years) were divided into two groups: Alcoholic or non-alcoholic. Participants were assigned to their respective group and matched based on the information provided on a health questionnaire. All participants completed a series of information processing measures. A 2 (Group) x 3 (Test) ANOVA with repeated measures on the last factor was used to compare reaction times of three separate tests of information processing ability. Unfortunately, the analysis suffered from lack of statistical power. However, data trends strongly suggested a difference between the alcoholic and non-alcoholic participants on all measures of information processing. Further, interactive trends of the data were noted with the alcoholics showing more deficits as a result of the more complex processing requirements. Future suggestions are to continue the work with more participants of more diverse socio-economic status, health, and alcohol behavior, as assessed through the a priori health questionnaire.
