Resumen en inglés The Rey Auditory Verbal Learning Test (RAVLT) is an episodic memory test that is influenced by demographic variables, such as age, education, and gender. Classic word list learning has also been well documented to be an experimental cognitive paradigm that is very useful for the detection of Alzheimer’s disease. The present study analyzed the performance of healthy elderly subjects on the RAVLT, describing the effects of age, education, and gender. To verify its construct validity, the RAVLT was compared with delayed recall and recognition scores on the Brief Cognitive Screening Battery (DR-BCSB). The sample comprised 183 cognitively healthy elderly subjects from outpatient care units of two university reference centers in Rio de Janeiro and São Paulo, Brazil. All participants were subjected to physical and neurological evaluation and neuropsychological assessment. Pearson’s correlation and Student’s t-test were used to investigate the influence of demographic variables on RAVLT performance. To verify convergent-type construct validity, a correlation between RAVLT and DR-BCSB scores was calculated. Significant correlations were found between age and ΣA1-A5 (r = -.383, p < .01), A5-A1 (r = -.054, p < .01), A7 (r = -.361, p < .01), and REC A (r = -.288, p < .01). Educational level correlated with ΣA1-A5 (r = .405, p < .01), A5-A1 (r = .184, p < .01), A7 (r = .334, p < .01), and REC A (r = .329, p < .01). No correlation was found between gender and RAVLT performance. A significant correlation was also found between RAVLT and DR-BCSB performance (r = .5, p < .01). These results revealed some normative data and convergent-type construct validity of the RAVLT for a Brazilian elderly population
