Effects of experience and processing demands on visual information acquisition in drivers

摘要

This study investigated the differences between novices and experienced drivers in their distribution of visual attention under different levels of cognitive load imposed by different types of road, and as reflected in their visual search strategies. The task involved a 20-min drive on various roads while the drivers' eye movements were recorded. The measures taken included fixation durations, as an indicator of the time taken to assimilate fixated objects, and the variance of fixation co-ordinates o describe the spread of search in both the horizontal and vertical axes.
