The objective of the present study was to analyze the influence of demographics variables, such as age. gender, and education, on RAVLT performace in young and alderly adults. A portuguese version of the RAVLT was administered to 302 healthly participants. Subjects were from both genders, ranging in age from 17 to 85 years (mean 50.6 15.9 years) and in education from 1 to 20 years (mean 11.3 3.7 years). Participants were grouped by age 17-34 years old, 34-49 years old, 50-64 years old, and 65-85 years old. Pearson's Correlation analysis showed a significant association between RAVLT performace and both age and education (p<001), but not between RAVLT performace and gender. Two-way analysis of varience revealed significant effects of age on all RAVLT measurements and significant effects of years of education on all measurements, with the exception of recognition. The present data indicate that participant age and education significantly influence performace on the RAVLT.
