Effects of self-motion and illuminance on visual attention in traffic driving environment

摘要

Studies have shown that prior information concerning the spatial location of a subsequent target facilitates the selection of that target for further visual processing in 3D space. Using Posner's paradigm, our work examined the reaction time of drivers when cue duration and peripheral environment luminance was changed, and explored the effect color and location on reaction time. Experiment 1 showed that reaction time was not affected by cue duration, and that shifts of attention operated more efficiently for cue location validity. Experiment 2 showed that there was no main effect of background luminance on reaction time. Experiment 3 showed that location produces a greater effect than color.
