Are globality and locality related to driver’s hazard perception abilities? Conference Paper uri icon


  • Driving requires various skills, amongst them hazard perception that has been directly linked to involvement in traffic accidents. Navon-type tasks may provide a framework for understanding perceptual processing and logical reasoning. Yet, limited attempts were made to formulate associations between globality and locality in visual processing and perception of real world stimuli like hazards while driving. A study aimed to link Navon-type tasks with hazard perception abilities of drivers was conducted. A sample of 39 young novice drivers, 60 adult students, and 21 adult drivers completed a battery of cognitive test including Navon tasks. Then they performed a hazard perception test (HPT), in which they observed video-based traffic-scenes and were asked to press a response button each time they detected a hazard, followed by classification and rating of hazardous scenes. While there is a known statistically significant effect for experience, results reveal significant ties between global and local processing, and hazard perception. The significant effect of the global/local scores in the Navon tasks on performance on a real-world traffic situation test suggests that the Navon tasks, as well as other cognitive tests may be useful in predicting performance in real world complex situations such as driving.
