DESCRIPTION:This week we will discuss and debate a paper by Bécu and coll
 eagues (2023).\n\nAbstract: “Human spatial cognition has been mainly cha
 racterized in terms of egocentric (body-centered) and allocentric (world-c
 entered) wayfinding behavior. It was hypothesized that allocentric spatial
  coding\, as a special high-level cognitive ability\, develops later and d
 eteriorates earlier than the egocentric one throughout lifetime. We challe
 nged this hypothesis by testing the use of landmarks versus geometric cues
  in a cohort of 96 deeply phenotyped participants\, who physically navigat
 ed an equiangular Y maze\, surrounded by landmarks or an anisotropic one. 
 The results show that an apparent allocentric deficit in children and aged
  navigators is caused specifically by difficulties in using landmarks for 
 navigation while introducing a geometric polarization of space made these 
 participants as efficient allocentric navigators as young adults. This fin
 ding suggests that allocentric behavior relies on two dissociable sensory 
 processing systems that are differentially affected by human aging. Wherea
 s landmark processing follows an inverted-U dependence on age\, spatial ge
 ometry processing is conserved\, highlighting its potential in improving n
 avigation performance across the lifespan” (Bécu et al.\, 2023).\n\nRef
