Résumé / Abstract

Three mood states (anger, sadness and neutral) have been induced to reveal their effects on the localization of road elements. We used a modified version of the jumble scenes paradigm to provide evidence for the existence of driving-related schemata which appeared to be guiding visual search. The type of road (e.g., an intersection) activates particular schemata which induce where particular road users and road elements can be expected. It seems that participants previously induced in sadness are less relying on their schemata than other participants. Negative mood also promotes the use of a detail-oriented processing of information. Moreover, studies, about the effect of sadness on driving, showed that this mood state increases irrelevant thought, and decreases the attentional resources leading to inattention. But, some studies suggest that negative moods should be disentangled according to the arousal dimension (exciting versus calming) rather than according to the valence (the hedonic value) dimension. The results reported here revealed that all groups used their visual schemata to localize road elements. But, participants induced in anger, were slower to locate road elements than participants induced in sadness and in neutral mood. Further analyses revealed that participants of the anger group did not use their driving schemata to localize road signs, suggesting that the information processing is different between the localization of road signs and road users under anger mood. The sadness group made more errors in their detections, confirming that sadness leads to irrelevant thoughts and inattention
