Navon效应(Navon，1977)是一种在处理复合图案时，自动倾向于先处理全局图像，再处理局部细节的现象。然而，最近的几项研究报告称，注意力缺陷/多动障碍(ADHD)缺乏这种效应。虽然之前的研究表明，Navon效应受视角的影响很大，但这种现象是否也会在ADHD中观察到，还有待了解。方法采用三种不同的局部刺激视角，对ADHD患者(n=15)和对照组(n=17)进行Navon类层次结构字母的整体和局部加工研究。结果与非ADHD患者相比，ADHD患者在不同视角下均表现出缺乏Navon效应而无局部加工缺陷。结论ADHD患者可概括为缺乏全局优先权和无局部加工缺陷的全局-局部干扰。这表明ADHD患者在处理“整体情况”方面遇到了困难，这也挑战了ADHD的诊断和统计手册(第5版；美国精神病学协会，2013年)标准，其中强调了不密切关注细节。此外，目前的结果对了解ADHD具有重要意义，也可能具有重要的临床价值。(保留所有权利，《心理信息数据库记录(C)2022 APA》)
ObjectiveThe Navon effect (Navon, 1977) is an automatic tendency to process the global picture prior to local details when processing compound patterns. However, several recent studies have reported that this effect is lacking in attention-deficit/hyperactivity disorder (ADHD). Although previous research has shown that the Navon effect is strongly affected by visual angles, whether this phenomenon will also be observed in ADHD is yet to be understood. We examine the lack of the Navon effect in ADHD under various visual angles to ensure that this phenomenon is not an artifact of saliency.MethodBy employing three different visual angles for the local stimuli, global and local processing of Navon-type hierarchical letters was examined in participants with ADHD (n= 15) and a comparison group (n= 17).ResultsADHD participants presented with a lack of the Navon effect without local processing deficit regardless of visual angle, in comparison to non-ADHD participants.ConclusionA lack of global precedence and global-to-local interference without local processing deficit can be generalized in ADHD. This suggests that people with ADHD experience difficulties in processing the “whole picture,” and it also challenges the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; American Psychiatric Association, 2013) criteria of ADHD in which the failure to pay close attention to details was emphasized. Moreover, the current results have important implications for understanding ADHD and could also have significant clinical value.(PsycInfo Database Record (c) 2022 APA, all rights reserved)
