Higher cue utilization in driving supports improved driving performance and more effective visual search behaviors

Abstract

Introduction: Once qualified, drivers rarely receive objective feedback concerning their performance. This is especially the case in the context of cognitive skills such as situation assessment. The aim of this study was to test the construct validity of an online assessment of motor-vehicle driver cue utilization that forms the foundation for situation assessment.

Method: Seventy-one undergraduate Psychology students with broadly comparable driving experience completed a motor-vehicle driving version of EXPERTise 2.0, an online tool that enables inferences concerning the utilization of cues based on responses to task-related stimuli. They also completed a simulated driving task while fitted with an eye tracking device, during which a range of hazards were presented with participants' responses recorded.

Results: The results indicated that higher cue utilization was associated with fewer driving errors and collisions, fewer visual fixations, and fewer saccades in comparison to participants with lower cue utilization.

Conclusion: The results provide support for the construct validity of EXPERTise 2.0 as an effective measure of cue utilization in the context of driving.

Practical applications: Providing comparative feedback to drivers concerning their development of situation assessment skills may provide opportunities for further training and development, thereby reducing the likelihood of motor-vehicle accidents.
