A body of experimental, neuropsychological, and neuroanatomical evidence suggests a relationship between autobiographical memory and the ability to generate mental images. This study investigated this relationship in Alzheimer's disease (AD).
Twenty six AD participants and 28 control participants were asked to retrieve 2 autobiographical events. They were also administered measures of visual imagery (i.e., the taller/wider task), and spatial imagery (i.e., the clock angles task).
Analysis showed preserved autobiographical memory and visual imagery but compromised spatial imagery in AD. Significant correlations were observed between autobiographical memory and visual and spatial imagery in AD and control participants. However, autobiographical memory was predicted by visual but not by spatial imagery.
The ability to retrieve (i.e., visual imagery) and manipulate mental images (i.e., spatial imagery) seems to be related with autobiographical recall in AD. In particular, visual imagery may contribute to autobiographical retrieval in AD participants by providing them with visual cues that increase the ease and speed of search through the hierarchical structure of autobiographical memory.

大量的实验、神经心理学和神经解剖学证据表明，自传体记忆与产生心理意象的能力之间存在关系。本研究在阿尔茨海默病（AD）中对此关系进行了研究。
要求 26 名 AD 参与者和 28 名对照组参与者检索 2 个自传体事件。他们还接受了视觉意象（即 taller/wider 任务）和空间意象（即时钟角度任务）的测量。
分析表明，AD 患者的自传体记忆和视觉意象保持完好，但空间意象受损。AD 和对照组参与者的自传体记忆与视觉和空间意象之间存在显著相关性。但是，自传体记忆仅由视觉意象预测，而不由空间意象预测。
在 AD 中，检索（即视觉意象）和操纵心理意象（即空间意象）的能力似乎与自传体回忆有关。具体而言，视觉意象可能通过为 AD 参与者提供增加通过自传体记忆的层次结构进行搜索的便利性和速度的视觉提示，从而有助于自传体检索。（PsycINFO 数据库记录（c）2019 APA，保留所有权利）。
