ABSTRACT

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.

摘要

与成人相比，儿童的视觉搜索不仅准确性较低，而且组织性较差。但是，儿童的视觉搜索策略尚未得到广泛研究，也没有在临床实践中对其进行评估。工作记忆对于视觉搜索策略的执行和维护起着至关重要的作用。很少有研究探讨视觉搜索组织与儿童工作记忆之间的联系。在本研究中，有54名小学生执行了取消任务（贝尔测试）和工作记忆测试（跨度任务）。我们的研究结果表明，与视觉搜索的准确性相反，视觉搜索的组织与工作记忆尤其是与中央执行组件的效率显着相关。因此，
