Samenvatting
This study employs a multidimensional fatigue scale in 3 studies of simulated driving performance. In all 3 studies drivers performed both a fatiguing drive in which a character detection task was performed and a control drive in which no extra task was included. Drivers completed the fatigue scale and measures of mood, cognitive and motivational components of subjective states before and after both drives. The study had 3 main aims - a) to determine whether fatigue is characterised by a single dimension only, b) to examine the relationship between fatigue and general state dimensions and c) to determine whether driving fatigue relates only to driver stress traits or to personality in general as well.
