RESUMO
The Paced Auditory Serial Addition Test (PASAT) is one of the most used neuropsychological tests to assess information processing speed and working memory in brain injured patients. This study was carried out with the purpose of obtaining normative data for the PASAT-3â³ in a healthy Argentinean population, which would result in a reference control population. The PASAT-3â³ was administered in a sample of 296 healthy voluntary subjects, born and living in Argentina. The age range went from 20 to 70 years-old. The level of education was 0 to 13 or more years of schooling. The sample obtained a mean of 44.60 (SD = 10.72) in the PASAT-3â³. It was found that the score obtained in the PASAT-3â³ was related to the age and the level of instruction of the participants. Their performance diminished as age increased and, conversely, it increased as the level of instruction was higher. Normative data was obtained for a Latin American population from Argentina. Percentile distributions obtained by decades of age and different levels of education should be considered as useful reference values for clinicians and investigators when applying the PASAT-3â³ to assess cognitive function in different pathologies.
