Fig. 1From: Gaze behavior and cognitive states during fingerprint target group localizationTwo example sets of images used in find-the-target tasks. In each trial, one of the left images (Latent, Plain, or Cropped) was paired with the right image (mated exemplar). The yellow squares indicating the target areas were in the images shown to the participants. All images are at the same scale. Target area is 3.8 mm × 3.8 mm. Latent images (left column) are slightly cropped for publication. See Additional file 1: Appendix SI-3 for the other image setsBack to article page
