Figure 2.

Examples of visual exploration by group. The subpanels show, for different images and the four groups of participants (Fig. 1, description), the spatial distributions of the probabilities to gaze different locations (pooled across participants and smoothed with a 2D Gaussian unit kernel), superimposed over line-drawing sketches of the original images. Warmer colors indicate a higher probability to gaze a location. Yellow contours indicate areas that span the top 50%, 75%, and 95% of the spatial distribution. As this distribution is constructed from all gaze eye-tracking samples (each occurring every 2 ms), these maps are equivalent to the spatial distributions of dwell time. The mean of entropy and AUC values for each of the four images are indicated by the corresponding symbol (star, square, and left and right pointing triangles) in Figure 3, b and f. The last column shows the DG-II and ICF predictor maps for each image. Extended Data Figure 2-1 shows the grand average of the spatial distributions of the probability to gaze a certain location across all images separately for each of the four groups. In addition, the corresponding grand average DG-II and ICF predictor maps are displayed.
