Selective visuo-spatial memory deficits can seriously affect many aspects of daily life; for example, an individual may not remember where he put an object or which path he took to reach his destination. In general, visuo-spatial memory is assessed through pen-and-paper tests that mainly assess memory components in peripersonal space. Recent studies (Piccardi et al. in Exp Brain Res 206:171-177, 2010; Piccardi et al. in Neuropsychol Dev Cogn B Aging Neuropsychol Cogn 18:362-384, 2011) have shown that brain-damaged patients selectively fail on navigation memory tasks but not on other tests of visuo-spatial memory ability. These findings underline the need for a standardized test that measures memory in navigation separately from other types of visuo-spatial memory. Here, we report the validation of the Walking Corsi Test (WalCT: Piccardi et al. in Neurosci Lett 432:127-131, 2008) on 289 individuals aged 15-86 years. The WalCT is a new instrument that assesses topographical memory in real environments and reproduces on a large-scale version the Corsi Block-Tapping Test (CBT: Corsi in Unpublished doctoral dissertation, McGill University, Montreal, 1972). The WalCT has been used in clinical practice and has proven sensitive in detecting navigational memory deficits even in individuals who have no other memory impairments (Piccardi et al. in Exp Brain Res 206:171-177, 2010; Piccardi et al. in Neuropsychol Dev Cogn B Aging Neuropsychol Cogn 18:362-384, 2011; Bianchini et al. in Neuropsychologia 48:1563-1573, 2010 ).
选择性视空间记忆缺陷会严重影响日常生活的许多方面；例如，个体可能会忘记他把物体放在哪里，或者他走哪条路到达目的地。一般来说，视空间记忆是通过纸笔测试来评估的，这些测试主要评估近体空间的记忆成分。最近的研究（Piccardi 等人，《实验脑研究》206：171-177，2010 年；Piccardi 等人，《神经心理学发展认知 B 衰老神经心理学认知》18：362-384，2011 年）表明，脑损伤患者在导航记忆任务中选择性地失败，但在其他视空间记忆能力测试中不会失败。这些发现强调需要一种标准化的测试，该测试将导航记忆与其他类型的视空间记忆分开进行测量。在这里，我们报告了对 289 名 15-86 岁个体进行行走 Corsi 测试（WalCT：Piccardi 等人，《神经科学快报》432：127-131，2008 年）的验证。WalCT 是一种新的仪器，可评估真实环境中的地形记忆，并在大型 Corsi 方块敲击测试（CBT：Corsi 在未发表的博士论文，麦吉尔大学，蒙特利尔，1972 年）上复制。WalCT 已在临床实践中使用，并已证明在检测导航记忆缺陷方面具有敏感性，即使在没有其他记忆障碍的个体中也是如此（Piccardi 等人，《实验脑研究》206：171-177，2010 年；Piccardi 等人，《神经心理学发展认知 B 衰老神经心理学认知》18：362-384，2011 年；Bianchini 等人，《神经心理学》48：1563-1573，2010 年）。
