Study title

In this study we monitored eye movements of 26 healthy adults during a repetitive banknote authentication task involving genuine and counterfeit banknotes. On each trial a banknote was presented and eye movement monitoring (EyeLink 1000) was initiated. Recording continued until the participant decided if the banknote was real or fake. The test session comprised a succession of 20 genuine notes, a single counterfeit, another 13 genuine notes, and, lastly, another counterfeit. This series created three note conditions: pre-counterfeit genuine, post-counterfeit genuine, and counterfeit (first and second) notes. We compared the proportion of fixations directed at each of four different areas of interest (AOIs) on the banknote and also recorded the duration of each fixation for each AOI. Performance on the authentication task was also recorded. Participant age, sex and cash handling experience was also recorded
