Two Wrong Decisions are Worse Than One: Dual-Task Performance on an ID Screening Task

Using identification documents (IDs) is important to many security-related professionals who compare an ID to a live person. ID screening is a two-part process - the card and identity need to be authenticated. Psychology research has focused on identity verification without considering card verification or eye movements. Participants will wear eye tracking glasses while making 50 card and/or identity authentication decisions. Each trial will present a physical ID card depicting a facial image beside a facial video. Afterwards, participants will complete a standard face matching test (KFMT). We predict that dual-task interference (the Card and Identity authentication) will reduce accuracy and increase reaction times compared to single-task performance (Card or Identity verification). We also predict that fixation count, fixation duration, and saccade count may vary by condition and accuracy. This research may inform real-world ID screening situations to support implementation-oriented initiatives to increase safety at ID screening checkpoints.
