Impulsivity and Aggression in Young Drivers Assessed in Short Driving Simulator Scenarios
MetadataShow full item record
Interactions between gender, impulsivity, and driving anger on young persons' driving behaviour were assessed in an immersive driving simulator. Personality measures included the Impulsivity Questionnaire and Driving Anger Scale, and the Driving Anger Expression Scale, assessed prior to simulated driving behaviour. Five short driving scenarios were used: T-junction gap-acceptance, following distance, amber/red traffic light acceptance, merging following traffic lights, and overtaking. Two forms of each scenario were created: a provocative ('hot') and matched neutral ('cool') form. For example, in scenario involving merging lanes following a traffic light, in the hot form, a car in the other lane would 'race' the operator's vehicle to the merge point; in the cool form, the other vehicle would merge in a more orderly fashion. Dependent variables comprised difference scores derived from the vehicle dynamics data between the hot and cool driving scenarios. Fifty-two participants (55% female; Age M = 19.13) were selected from an initial screen of 278, half of whom had high scores on impulsivity and anger, while the other half had low scores on the same measure . Results included a significant 3-way interaction between Gender, Impulsivity, and Driving Anger (p = .002), a main effect of Gender (p = .002), and a main effect of Impulsivity (p = .037). Overall young impulsive males had a higher tendency for risky driving than females did. However, high Impulsivity, low Driving Anger males exhibited risky driving behaviour in a different way, which suggested the presence of other motivational factors, such as venturesomeness.
