Some fundamental bibliographic information related to modifications of psychophysiological functions trough ageing processes are synthetised in this report. From this review, it appears that perceptual and cognitive processes decline as a function of age with an important intraindividual and interindividual variability. This strong heterogeneity concerning elderly abilities would correspond to a lack of precise matching between functional and chronological age. Available data about perceptual abilities of french population are limited. Thorough investigations in this area would allow to sep up a reference framework for a better understanding of difficulties encountered by elderly in transport situations. (Author/Publisher)
