Effects of Self-Motion and Illuminance on Visual Attention in Traffic Driving Environment

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.
