The data set provides summarised eye movement data form 26 healthy adults obtained 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. 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

Eye movement recordings. 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. The data set contains Participant age, sex and cash handling experience, and a performance measure (d'). Then for each note condition, the individual average proportion of fixations directed at each of four different areas of interest (AOIs) on the banknote; total cumulative dwell time prior to decision, total number of fixations made prior to decision, the proportion of fixations directed at each of four different areas of interest (AOIs) on the banknote for the first. second, third and fourth fixation; and the duration of each fixation for each AOI is provided. Other eye movement data is also provided.
