This dissertation presents a systematic review study, which investigated the role of age on cancellation tests, and an empirical study, which compared the performance between middle-aged adults and older adults in the Bells Test. In the systematic review, abstracts were sought in the databases Lilacs, Pubmed, PsycINFO and Scopus from 1989 to 2010, with the descriptors age or aging and bells cancellation test/task or visual hemineglect or visual neglect. There was a shortage of international papers that study the cancellation paradigm in relation to the variable age in healthy samples, and there were no studies in the national literature. Regarding the comparative empirical study, a sample of 80 neurologically healthy adults, high-educated, 40 from 40 to 59, and 40 from 60 to 75 years old, was assessed using the Bells Test. Its accuracy and speed processing were compared by an ANCOVA (years of education and frequency of writing and reading habits as covariants). The distribution of the qualitative data was compared with chi-square test. There were no differences between groups of middle-aged adults and older adults in the quantitative and qualitative performance of the Bells Test. We emphasize the need to invest in the Brazilian neuropsychological assessment field in obtaining a normative profile of Brazilian samples in this paradigm, by investigating the role of age in different age groups as the oldest old, and at different levels of education. Furthermore, data of clinical samples, neurological and psychiatric, must also be obtained to investigate the diagnostic accuracy of visual unilateral neglect.
