威廉姆斯综合症 (WS) 和自闭症谱系障碍 (ASD) 都被描述为优先处理局部信息，而唐氏综合症 (DS) 的报告倾向是处理全局刺激。我们设计了跨综合征、跨任务比较，以揭示这些疾病的局部/全局处理的相似性和差异。我们的深入研究比较了三种综合症的跨模式（听觉-语言/视觉-空间）和处理水平（高/低）的局部/全局处理。尽管文献中有这样的说法，患有 ASD 或 WS 的参与者未能表现出一致的局部处理偏差，而患有 DS 的参与者未能表现出可靠的全局处理偏差。根据刺激和任务的性质，局部和全局处理偏差在所有三种神经发育障碍中都很明显。这些发现表明，患有神经发育障碍的个体不能简单地被描述为局部或全局处理者。
Both Williams syndrome (WS) and Autism Spectrum Disorder (ASD) have been characterized as preferentially processing local information, whereas in Down syndrome (DS) the reported tendency is to process stimuli globally. We designed a cross-syndrome, cross-task comparison to reveal similarities and differences in local/global processing in these disorders. Our in-depth study compared local/global processing across modalities (auditory-verbal/visuo-spatial) and levels of processing (high/low) in the three syndromes. Despite claims in the literature, participants with ASD or WS failed to show a consistent local processing bias, while those with DS failed to show a reliable global processing bias. Depending on the nature of the stimuli and the task, both local and global processing biases were evident in all three neurodevelopmental disorders. These findings indicate that individuals with neurodevelopmental disorders cannot simply be characterized as local or global processors.
