Abstract

Identification card (ID) screening occurs in everyday life prior to purchasing goods or gaining access to establishments. Unfortunately, contextual factors can bias face-matching (e.g., low prevalence effect, document bias, and size disparity). We focused specifically on color incongruity (i.e., comparing two identities is biased when one facial image is in color and the other is grayscale). Participants wore eye-tracking glasses while comparing 48 physical IDs (printed in color [congruent] or grayscale [incongruent]) to a color facial video. Participants answered the question, “Are these pictures of the same person?” using a scale from 1 Definitely No to 6 Definitely Yes. Data collection is ongoing. However, we predict differences in patterns of response bias and eye movements for incongruent color compared to congruent color trials. This preventable incongruency has implications of fraud and criminality that can affect security, law enforcement, and private citizens. Influencing the future of ID verification systems and protocols.
