The association between a word and typical location (e.g., cloud—up) appears to modulate healthy individuals’ response times and visual attention. This study examined whether similar effects can be observed in a clinical population characterized by difficulties in both spatial representation and lexical processing. In an eye-tracking experiment, participants categorized spoken words as either up-associated or down-associated. Parkinson’s disease patients exhibited a tendency to maintain their visual attention in the upper half of the screen, however, this tendency was significantly lower when participants categorized concepts as down-associated. Instead, the control group showed no preference for either the upper or lower half of the screen. We argue that Parkinson’s disease patients present an over-reliance on space during word categorization as a form of cognitive compensation. Such compensation reveals that this clinical population may use spatial anchoring when categorizing words with a spatial association, even in the absence of explicit spatial cues.

帕金森氏病单词分类过程中作为认知补偿的策略性空间锚定：来自眼动的证据。

单词和典型位置（例如，云层向上）之间的关联似乎可以调节健康个体的响应时间和视觉注意力。这项研究检查了在以空间表示和词汇处理均困难为特征的临床人群中是否可以观察到类似的效果。在眼动追踪实验中，参与者将口语分为上关联或下关联。帕金森氏病患者在屏幕的上半部分表现出保持视觉注意力的趋势，但是，当参与者将概念归类为向下关联时，这种趋势显着降低。相反，对照组对屏幕的上半部分或下半部分均不显示偏好。我们认为帕金森氏病患者在单词分类过程中表现出对空间的过度依赖，这是认知补偿的一种形式。这样的补偿表明，即使在没有明确的空间提示的情况下，当将具有空间关联的单词分类时，该临床人群也可以使用空间锚定。
