Abstract
Trail Making Test (TMT) is one of the most widely used tests to evaluate attentional processes since its resolution requires the indemnity of multiple attentional aspects that underlie the correct execution of the task. The aim of this study was to update TMT norms for the Argentine population of Ciudad Autonoma de Buenos Aires and Gran Buenos Aires. The sample consisted of 407 participants (59% women), aged between 16 and 90 years, with educational level from incomplete primary to postgraduate. The sample was divided into four age groups and three educational levels. Special norms were made for individuals with low educational level because age did not differentiate their performance. The present TMT standardization includes the types of errors that may occur in part A and B of the test. This study allows for representative and up-to-date norms according to the socio-demographic characteristics of the population under investigation.
