Presented at First international conference on driver distraction and inattention (DDI 2009), Gothenburg, Sweden, September 28-29, 2009

This paper presents some results of an experiment on attention and decision making, correlated to a perceptive and memorizing exploration (cognitive and conative tests and neuropsychological measurements) carried out during a simulated driving task in a magnetoencephalography environment (MEG). MEG data are available in Fort & Delpuech and Fort & al. [1, 2]. Technical aspects of the simulation are presented in Foliot & al. [3]. Each subject answered questions and perform four kinds of testing in order to determine the psychological effect of a double task (paying attention to radio broadcasts) on attention while driving: a) General self-assessment, to evaluate internal states before and after the experiment; b) Evaluations on perceived “task difficulty” and “tiredness” after each of 18 driving sessions, as well as short-term memory on radio contents (in the double task condition only); c) Incident long-term memorizing (visual recognition and hearing recall); d) Finally, a debriefing questionnaire to assess to the subjective awareness of double task (DT) effects on attention while driving.
