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 = .310), whereas the influence of age on this score was lower (R = .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 (R = .039), whereas age was responsible for R = .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.
图卢兹-皮埃龙取消测试（TP）是评估选择性/持续性注意力、加工速度和视知觉能力的经典心理计量学工具。它常用于癫痫、多发性硬化症或阿尔茨海默病等神经疾病。它包含两个主要指标：工作效率（WE）和离散指数（DI）。本研究旨在为葡萄牙健康成年人样本提供 TP 的常模分数。TP 按照标准评估方案，对 357 名认知正常的受试者进行了测试，年龄在[45 至 86]岁之间。常模分数根据年龄和教育程度进行了调整。教育是 TP-WE 的主要预测因素（R =.310），而年龄对该分数的影响较低（R =.191）。这两个变量解释了结果的 50.1%。关于 TP-DI，教育也是结果的主要预测因素（R =.039），而年龄则负责 R =.011，两者共同解释了 TP-DI 变异的 5%。TP 的表现受年龄和教育的强烈影响。这是葡萄牙人口中首次在 45 岁以上年龄组中进行的关于建立常模数据的研究，可在临床和研究环境中进行可靠的评估。
