Figure 6.
(a) During delayed recognition test trials, average fixation duration for mouths changed with age typically (TD, dark gray bars), increasing from childhood to adolescence, but not in autism (ASD, light gray bars). TD children made shorter fixations to the mouth than did children with autism, but groups did not differ in adolescence or adulthood. (b) Fixation count for the mouth did not significantly differ between groups and age groups during delayed recognition test trials.
