Figure 4. Focal and ambient fixation modes, between-group comparison, and their relation to the Proximity Index (PI) across ASD and TD groups.

Figure 4.

(A1) Relative proportion of focal and ambient fixations in a sample of 51 TD children and 166 ASD children. Box-and-whisker plots illustrate the distribution of fixation proportions. The interquartile range (IQR) is represented by each box, with the median shown as a horizontal line. Whiskers extend to the most extreme data points within 1.5 IQR from the box, as per Tukey's method. Differences between groups were statistically assessed using the Mann-Whitney U test, with asterisks (****) indicating p-values less than 0.0001. (A2 & A3): Scatter plots show the correlation between the proportion of focal (A2) or ambient (A3) fixations and PI. Red points represent ASD individuals and blue points represent TD individuals. Spearman's correlation was used for analysis. Each group's data is fitted with its own linear regression line and includes 95% confidence bands.
