Abstract

ID screening is a two-part process — the card and identity must be authenticated. Psychological research has typically focused on identity verification without considering card verification. To fill this gap, the present study had participants complete an ID verification task while wearing eye-tracking glasses to record gaze behavior during face-matching decisions. After 2 practice trials, a research assistant presented 48 physical ID cards with embedded facial images, one at a time, beside a computer monitor that presented a facial videos and calendar date. Participants were asked to decide if the ID card was valid on a 6-option scale from Definitely Yes to Definitely No in response to one of three randomly assigned authentication conditions: date authentication only, face authentication only, or date and face authentication. I predicted that dual-task interference would affect accuracy. I also predicted that eye-tracking metrics (e.g., fixation counts and duration) would vary by condition and accuracy.
