Résumé
None of the previous studies on aging have tested the influence of action with respectto the degree of interaction with the environment (active or passive navigation) and thesource of itinerary choice (self or externally imposed), on episodic memory (EM) encoding.The aim of this pilot study was to explore the influence of these factors on feature binding(the association between what, where, and when) in EM and on the subjective sense ofremembering. Navigation in a virtual city was performed by 64 young and 64 older adults inone of four modes of exploration: (1) passive condition where participants were immersedas passengers of a virtual car [no interaction, no itinerary control (IC)], (2) IC (the subjectchose the itinerary, but did not drive the car), (3) low, or (4) high navigation control (thesubject just moved the car on rails or drove the car with a steering-wheel and a gas pedalon a fixed itinerary, respectively). The task was to memorize as many events encounteredin the virtual environment as possible along with their factual (what), spatial (where), andtemporal (when) details, and then to perform immediate and delayed memory tests. Anage-related decline was evidenced for immediate and delayed feature binding. Comparedto passive and high navigation conditions, and regardless of age-groups, feature bindingwas enhanced by low navigation and IC conditions. The subjective sense of rememberingwas boosted by the IC in older adults. Memory performance following high navigation wasspecifically linked to variability in executive functions.The present findings suggest that thedecision of the itinerary is beneficial to boost EM in aging, although it does not eliminateage-related deficits. Active navigation can also enhance EM when it is not too demandingfor subjects’ cognitive resources
