Description
Summary:Cancellation tests are traditionally used in neuropsychological assessment of attention and psychomotor speed, with the traditional task of marking targets. The Bells Test, internationally acknowledged for its contribution to the diagnosis of visual hemineglect, was developed with the task of circling all the bells as quick as possible. This paper aimed at verifying whether there are differences in performance between two versions of application – bells with circles and bells with straight lines – in the same sample consisting of 88 neurologically healthy adults from 19 to 75 years of age, with at least 5 years of formal education. The sample was evaluated in the same session with the two versions in an alternative manner. Accuracy and time scores were compared by the Wilcoxon test. The performance time of the marking task was lower than in the circular version. Thus, the two versions do not seem to be totally equivalent. Studies are suggested to standardize the bells with straight lines version, as well as to describe clinical samples, especially those with hemineglect as a sequelae.
