Abstract

The attentional effects of peripheral priming cues on reflectance report were assessed using a visual perception task. Previous research has demonstrated that peripheral priming cues result in an increase in visual acuity in the primed area of the visual field directly following the cue. Prior studies have looked at this priming effect in controlled laboratory settings in which participants are exposed to basic color primers and cues. This research seeks to extend these results into a more complex driving scene in an attempt to increase the external validity. Specifically this study used road sign cues as primers and a figure of a pedestrian as the stimulus in a driving scene. The accuracy with which the participants could recall the color that the pedestrian was wearing after each trial was the analyzed. Our results showed that the participants’ report accuracy was higher when the stimulus was presented in the valid location, or in the same area as the street sign cue, and the report accuracy was lower when the stimulus was presented in the invalid location, or in a different location as the street sign. Our results also indicate that the more extreme reflectance levels presented with the pedestrian were recalled with less error than the intermediate reflectance levels.
