Eye tracking demonstrates reliable gaze differences to features of videos. A ASD versus TD comparison in their percentage of total gaze time to faces in the stimulus video Episode A. Error bars span the 2.5–97.5th percentiles, boxes span the 25th to 75th percentiles, and horizontal black lines indicate medians. Effect size of the difference between groups (Cohen’s d) is shown on top of the plot. Individuals are denoted by distinct red-yellow spectrum colors based on their percentage of gaze time to faces in Episode A and the same participant-wise colors were used for Episode B (also for Fig. 2). Inverted triangles: participants tested at Caltech; circles: participants tested at Indiana University. B Same plot as in A, but for data from video Episode B. C Effect size of the differences between groups in their percentage of total gaze time to several areas of interest in two separate videos. Bar heights show Cohen’s d and error bars show their bootstrap confidence intervals. Saturated colors, asterisks, and p values show the statistical significance of Cohen’s d (p < 0.05, assessed with bootstrap tests, and corrected for multiple comparisons via false discovery rate); desaturated colors show nonsignificant differences. D Effect size of the differences between groups in their average correlation with reference gaze heatmaps created by either combining all TD controls (Ref. TD) or all autistic individuals (Ref. ASD). Same format as C
