Memory for familiar locations: The impact of age, education and cognitive efficiency on two neuropsychological allocentric tasks

This research aims to reconsider and support the use of spatial tasks based on familiar geographical information in the neuropsychological assessment of topographical (dis)orientation. Performance on two spatial tasks based on familiar information -l andmark positioning on a map and map of Italy - were compared in two studies assessing allocentric orientation among young and healthy elderly with different levels of education (Study 1) and elderly with and without probable cognitive impairment (Study 2). Results from Study 1 showed that the map of Italy task was affected by education, while the landmark positioning on a map was not. Results of Study 2 showed that both tasks were sensitive to different levels of cognitive functioning in a sample of community-dwelling seniors. Overall, spatial tasks based on mental representation of the hometown environment may be an important supplement in the assessment of allocentric topographical disorientation, discriminating typical from atypical aging.
