Analysis of accuracy in Gap, Step and Overlap tasks. A Plots of mean gain values. There was a significant difference in gain to first fixation between ASD and TD participants (A1), in the course of development (A2) and between tasks (A3). B Plots of mean coefficient of variation of gain values. While there were no significant differences between ASD and TD participants, there was a significant developmental improvement between age groups (B2), and between tasks. Bars indicate the standard error of the mean; *p < 0.05
