Abstract

Driving safety relies on a driver's ability to maintain their attentional focus and that mood is one of the factors which influences this ability. This driving simulator study used mind wandering theory to understand the changes in car following behaviour and driver glance patterns when affected by neutral, happy, sad and angry moods during car following. Two types of cognitive load were used to investigate ways of disengaging drivers from the mind wandering state. The moods were induced via music and mental imagery and assessed via self-reports and physiological measures. The results show that mood valence and arousal have different effects on driving safety, with negative moods resulting in the most dangerous driving, regardless of arousal. The cognitive load, in some cases, disengaged drivers from mood-related mind wandering. However, more detailed research is needed to understand the amount of load necessary for this disengagement in different moods. The importance of using driving-related measures together with glance patterns in mood research was highlighted to overcome ambiguities resulting from conclusions based on single measurements.
