Identifying the neural mechanisms underlying spatial orientation and navigation has long
posed a challenge for researchers. Multiple approaches incorporating a variety of …

Spatial orientation is an important function in daily life because it allows us to reach a target
place when moving through our environment, using self-centered (egocentric) or …

Spatial memory allows us to locate objects and organisms in space and move through the
environment. We frequently use two strategies for this purpose: egocentric, related to the …

Objectives Cognitive functioning is often impaired in mental and neurological conditions and
might fluctuate throughout the day. An existing experience-sampling tool was upgraded to …

Studies have shown that persons with Down syndrome (DS) exhibit relatively poor language
capacities, and impaired verbal and visuoperceptual memory, whereas their visuospatial …

We tested a densely amnesic patient (P9), with bilateral hippocampal damage resulting from
an autoimmune disorder, and 12 age-and sex-matched controls on a series of memory tasks …

Although normal aging has been related to several cognitive difficulties, other processes
have been studied less, such as spatial memory. Our aim was to compare egocentric and …

This paper describes how behavioral and imaging data can be combined with a Hidden
Markov Model (HMM) to track participants' trajectories through a complex state space …

Age-related impairments during spatial navigation have been widely reported in egocentric
and allocentric paradigms. However, the effect of age on more specific navigational …

A cerebellar role in spatial information processing has been advanced even in the absence
of physical manipulation, as occurring in mental rotation. The present study was aimed at …
