Visual search is not only less accurate but also less organized in children than in adults. However, visual search strategies in children have not been extensively studied and they are not evaluated in clinical practice. Working memory could play a critical role for the execution and the maintaining of a visual search strategy. Few studies if any have explored the links between visual search organization and working memory in children. In the present study, 54 primary school children performed a cancellation task (Bells test) and working memory tests (span tasks). Our results suggested that, contrary to visual search accuracy, visual search organization was significantly linked to working memory and, more specifically, to the efficiency of the central executive component. There is, thus, a real need to better understand the visual search process and to improve its assessment with cancellation tests in clinical practice.
视觉搜索不仅在儿童中不如在成年人中准确，而且也不如成年人中有序。然而，儿童的视觉搜索策略并没有得到广泛的研究，也没有在临床实践中进行评估。工作记忆可能对视觉搜索策略的执行和维持起着关键作用。很少有研究（如果有的话）探讨了儿童的视觉搜索组织和工作记忆之间的联系。在本研究中，54 名小学生进行了一项取消任务（Bells 测试）和工作记忆测试（跨度任务）。我们的结果表明，与视觉搜索准确性相反，视觉搜索组织与工作记忆显著相关，更具体地说，与中央执行成分的效率相关。因此，在临床实践中，确实需要更好地理解视觉搜索过程，并通过取消测试来改善其评估。
