Timeline view of all trials for one image set (FT1). Each row is one trial (i.e., different examiner); trials are sorted by Comparison time. (Left) Analysis and Comparison times are shown relative to the first fixation in the right image. (Right) First and last 10 s of Comparison phase. Each horizontal segment represents one fixation, with gaps shown in white (brief gaps are saccades; longer gaps are blinks or looking away from images). Longest timelines are truncated (longest Analysis times: 53, 64 s; longest Comparison times: 133, 167 s). Timelines for other image sets are in Additional file 1: Appendix SI-10. Left image fixations are not color-coded by location (in or out of the target area) because they are overwhelmingly in the target area (Additional file 1: Appendix SI-6.2)
