取消任务被广泛用于评估视觉空间功能和注意力。在发展中国家，对低识字率科目的认知评价仍然是一项挑战，因为有必要区分哪些是病态的，哪些是受教育程度低的偏见。研究了亚马逊河沿岸居民在结构化非语言消除任务中的表现，验证了他们的搜索策略（随机/有组织）、完成时间、正确取消目标的数量和假阳性目标的数量。在所有测量中，文盲和只受过几年教育的文盲（平均值= 0.8，标准差=1.6年）在表现和搜索策略上都存在差异。在有文化的群体之间，以及从未上过学的文盲和上过学的人之间，在搜索策略上存在显著差异，这表明与图形展示和写作组织的最小接触能够改变这种认知功能。(C) 2007年国家神经心理学研究院。Elsevier Ltd.出版。版权所有。
Cancellation tasks have been largely used to evaluate visuospatial function and attention. Cognitive evaluation of low literacy subjects remains a challenge in developing countries, when it becomes necessary to distinguish between what is pathological and what is biased by low education. Performance of river bank dwellers of the Amazon region was studied, in a structured nonverbal cancellation task, verifying their searching strategies (randomized/organized), time of completion, number of correct cancelled targets and number of false-positive targets. A difference was observed in performance and searching strategies between illiterates and literates with only a few years of schooling (mean= 0.8, S.D.=1.6 years of education) across all measures. There was a significant difference between literate groups in the searching strategy, as well as between illiterates who had never attended school and those who had, showing that a minimal contact with graphic presentations and organization of writing was able to modify this cognitive function.
