摘要

块设计任务(block design task, BDT)是一项视觉空间测试，威廉姆斯综合征患者在该测试中表现不佳。然而，目前还不清楚是什么导致了他们的表现受损。这项研究调查了较差的表现是由视觉空间困难、执行功能困难、非典型的观察策略还是这些因素的结合造成的。11名WS患者与心理年龄(MA)和实足年龄(CA)匹配的对照组一起参加了研究。他们在服用BDT时记录眼球运动。停留时间和对感兴趣区域的访问与CA组不同，但与MA组不同。研究结果表明，WS患者的BDT能力是延迟的，但不是不典型的。延迟是由视觉空间和注意力转换困难造成的，而不是非典型的观看策略。

Block Design Performance in Williams Syndrome: Visuospatial Abilities or Task Approach Skills?

The block design task (BDT) is a visuospatial measure that individuals with Williams syndrome (WS) perform poorly on. However, it is unclear what underlies their impaired performance. This study investigated whether poorer performance is a result of visuospatial difficulties, executive function (EF) difficulties, atypical looking strategies, or a combination of these. Eleven individuals with WS participated alongside mental age (MA)- and chronological age (CA)-matched control groups. Eye movements were recorded while they took the BDT. Dwell times and visits to areas of interest in WS differed from CA, but not MA, groups. Findings suggest that BDT abilities of individuals with WS are delayed, but not atypical. Delays result from visuospatial and attention-switching difficulties rather than atypical looking strategies.
