Predicting Aberrant Driving Behaviour: The Role of Executive Function

The aim of the current study was to assess the relevance of three components of executive function: working memory, sustained attention and behavioral inhibition for explaining aberrant driving behavior, driving errors, driving violations and crashes. A total of 107 participants (M age = 30.2; 62% male) with a valid driving license participated in the study. A battery of cognitive assessments was administered, including the Wechsler Digit Span Backward task, Continuous Performance Task (CPT), Go/No-go task, and the Driving Behavior Questionnaire (DBQ). Results indicated that aberrant driving behavior and driving errors were significantly correlated to sustained attention and behavioral inhibition. Driving violations related to behavioral inhibition. Regression indicated that behavioral inhibition significantly predicted aberrant driving behavior, driving errors and driving violations. Gender predicted driving violations and driving errors. Number of reported crashes during the last year was related to driving errors, behavioral inhibition and driving violations. In conclusion, inhibitory control related to different aspects of driving indicating that impulsivity may underlie various aberrant driving behavior and crashes. It is discussed that poor inhibitory control could result in aberrant driving behavior causing conflict and leading to crashes.
