Abstract

The analysis of performances of individuals with Alzheimer's Disease (AD) on Cancellation Tasks provides useful information on the way they process their surrounding field, since these tasks require one to selectively attendto relevant features of the field while suppressing irrelevant ones. Inconsistently with the hypothesis of a general inhibitory breakdown in AD whichwould have predicted a considerable number of crossed distracters in AD individuals, previous results had shown that errors were predominantly omissions but rarely crossed distracters. However, our results on Zazzo's Cancellation Task showed that by increasing the features shared by the target and distracters, AD individuals also commit numerous crossed distractors. The results are interpreted in terms of inhibitory deficits. (C) 1999 Academic Press.
