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, ; Piccardi et al. in Neuropsychol Dev Cogn B Aging Neuropsychol Cogn 18:362-384, ) 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, ) 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memory in real environments and reproduces on a large-scale version the Corsi Block-Tapping Test (CBT: Corsi in Unpublished doctoral dissertation, McGill University, Montreal, ). 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, ; Piccardi et al. in Neuropsychol Dev Cogn B Aging Neuropsychol Cogn 18:362-384, ; Bianchini et al. in Neuropsychologia 48:1563-1573, ).
