先天性失语症是一种最近被定义为表现出色的个体无法形成自愿视觉意象的体验变异。由于视觉意象的这种特殊缺陷，失语症患者是探索视觉记忆表征本质的理想群体，特别是物体、空间和符号信息的相互作用。在这里，我们对失语症进行了大规模的在线研究，并揭示了他们的记忆表征中物体和空间内容的分离。六十一名失语症患者和具有典型意象的对照者研究了现实世界的场景图像，并被要求从记忆中绘制它们，然后在匹配的知觉条件下复制它们。 2,795 名在线评分员对绘图的物体和空间细节进行了客观量化。失语症参与者比对照组回忆起的物体要少得多，绘画中的颜色也更少，而且对语言支架的依赖程度更高。然而，失语参与者表现出与对照组相当的高空间准确性，并且记忆错误显着减少。这些组间差异仅在回忆过程中表现出来，在匹配的知觉条件下组间没有差异。失语症患者的这种特定于物体的记忆障碍为记忆中支持物体与空间信息的独立系统提供了证据。这项研究还为失语症作为人类意象体验的一种变异的存在提供了重要的实验验证。
Congenital aphantasia is a recently characterized variation of experience defined by the inability to form voluntary visual imagery, in individuals who are otherwise high performing. Because of this specific deficit to visual imagery, individuals with aphantasia serve as an ideal group for probing the nature of representations in visual memory, particularly the interplay of object, spatial, and symbolic information. Here, we conducted a large-scale online study of aphantasia and revealed a dissociation in object and spatial content in their memory representations. Sixty-one individuals with aphantasia and matched controls with typical imagery studied real-world scene images, and were asked to draw them from memory, and then later copy them during a matched perceptual condition. Drawings were objectively quantified by 2,795 online scorers for object and spatial details. Aphantasic participants recalled significantly fewer objects than controls, with less color in their drawings, and an increased reliance on verbal scaffolding. However, aphantasic participants showed high spatial accuracy equivalent to controls, and made significantly fewer memory errors. These differences between groups only manifested during recall, with no differences between groups during the matched perceptual condition. This object-specific memory impairment in individuals with aphantasia provides evidence for separate systems in memory that support object versus spatial information. The study also provides an important experimental validation for the existence of aphantasia as a variation in human imagery experience.
