The Toulouse-Piéron Cancelation Test (TP) is a classic psychometric tool for the assessment of selective/sustained attention, processing speed and visuo-perceptual abilities. It is commonly used in neurological disorders such as epilepsy, multiple sclerosis or Alzheimer's disease. It encompasses two main indexes: Work-Efficiency (WE) and Dispersion-Index (DI). The aim of this study is to provide normative scores for the TP in a sample of Portuguese healthy adults. The TP was administered to a convenience sample of 357 cognitively-dwelling subjects aged between [45 and 86] years old, following a standard assessment protocol. The normative scores were adjusted for age and education. Education was the main predictor of TP-WE (R
2 =.310), whereas the influence of age on this score was lower (R2 =.191). These two variables explained 50.1% of the variance of the results. Regarding TP-DI, education was also the main predictor of the results (R2 =.039), whereas age was responsible for R2 =.011 and together, they explained 5% of the variance of TP-DI. TP performances are strongly influenced by age and education. This is the first study focused on the establishment of normative data after the age of 45 in the Portuguese population, allowing a reliable assessment in both clinical and research contexts.
