Visuospatial perspective taking (VPT) refers to the process of mentally representing a viewpoint different from one's own. It is related to mental rotation and theory of mind and helps to support some complex spatial activities such as wayfinding. Despite research advances in spatial cognition, little is known about VPT in people with Down syndrome (DS). Here, we examined VPT in people with DS. A total of 38 individuals with DS (aged 12-25 years old) and nonverbal ability-matched typically developing (TD) children (aged 4-9 years old) participated. They completed two VPT tasks: the classic Piagetian Three Mountains Task and a modified version of the "Dog Task" (Newcombe & Huttenlocher, 1992). For both groups, the Three Mountains Task was more difficult than the Dog Task, implying the impact of task complexity on assessing VPT. However, the overall performance did not differ between the TD and DS groups in either VPT task. Implications of the results were discussed.
视空间观点采择（VPT）是指从自身视角出发，在心理上对不同视角进行表征的过程。它与心理旋转和心理理论有关，有助于支持一些复杂的空间活动，如寻路。尽管空间认知研究取得了进展，但人们对唐氏综合征（DS）患者的 VPT 知之甚少。在这里，我们研究了 DS 患者的 VPT。共有 38 名 DS 患者（12-25 岁）和非言语能力匹配的典型发育（TD）儿童（4-9 岁）参与了研究。他们完成了两项 VPT 任务：经典的皮亚杰三山任务和改良版的“狗任务”（Newcombe & Huttenlocher，1992）。对于这两个群体，三山任务比狗任务更难，这意味着任务复杂性对评估 VPT 的影响。然而，在这两个 VPT 任务中，TD 组和 DS 组的整体表现没有差异。对结果的含义进行了讨论。
