Résumé / Abstract
Many researches had showed that divided and switching attention deficits play a major role in mediating age-related driving difficulties. The older drivers seem to have difficulties in switching their attention from one aspect of the driving environment to another, meanwhile other authors showed that older drivers use relevant driving-related knowledge in their visual search. In the present research, we will explore the use of driving schemas according to age and distraction effects. We propose to examine the effects of aging on the localization of traffic object in natural scenes. The second goal tests older drivers' attention during the object localization. Participants have to search for objects in static driving scenes which are presented either as standard views from the driver's perspective or as randomly jumbled scenes. We suppose that the differences between search times in normal and jumbled scenes are a measure of the use of driving schemas.We use a dual task in order to know if older drivers' visual schemas of driving scene help them because of the lack of attention resources. This experiment includes eye tracking data that will help to clarify if the visual schemata allow the participants to predict rapidly the relevant areas of the scene in which particular objects are likely to appear and if they make fast initial eye movements to these locations. This research involves 24 older drivers (65 years old and more, driving at least 3000 km/year) and 24 experimented drivers (35 to 45 years old, and driving at least 10 000 km/year). First results will be presented.
