Effect of Confidence Level on Visual Search Patterns and Hazard Response of Young Drivers
Objective To investigate the effects of young drivers'overconfidence on visual search patterns of haz-ard perception under different hazard types.Methods A mixed experiment of 3(driving experience group:beginners,novices and experienced drivers)× 2(hazard types:overthazards,coverthazards)× 2(overconfidence classification:normal group and high group)was used.In the experiment,86 young drivers were presented with 24 videos of real traf-fic situations,and the participants were asked to react quickly by pressing buttons after seeing the hazard.Results(1)Young drivers with normal overconfidence group had faster response time to hazard,shorter first fixation time,lon-ger duration of first fixation point and longer total fixation time than those with high overconfidence group;(2)In the covert-hazard condition,the reaction time of beginners is significantly longer than that of novices and experienced drivers;There was no significant difference in response time between the three groups of drivers in overt-hazard con-dition.(3)In the covert-hazard condition,the first fixation time of beginners is significantly longer than that of nov-ices and experienced drivers;There was no significant difference in the first fixation time among the three groups of drivers in the overt-hazard condition.Conclusion The effects of overconfidence on response time and eye move-ment vary with the type of hazard.The response time and visual attention pattern of young drivers to coverthazards have obvious driving experience advantage effect.
