Abstract

Comparing identification documents (IDs) to the person presenting them is common before accessing restricted goods, areas, and services. Research has revealed ID comparison errors such as the low prevalence effect (i.e., rarity of fake IDs presented), document bias (i.e., reduced performance when ID comparison vs. real face comparison), size disparity (i.e., difference in size of ID and real face), and the cross-race effect (i.e., difficulty discerning faces of another race). The current study investigated how grayscale face images on IDs compared to color face images on IDs. Participants compared 48 IDs (color or grayscale) to a color video of a person. This task was performed while wearing eye tracking glasses. We predict errors in discriminability and response bias that stem from color disparity (i.e., difference in color between ID and video). Further, we included eye tracking technology to study eye movement differences between the two conditions.
