The mean percentage of hard task choices by reward probability for the ASD and Control groups. Significant group differences were detected at the 12% probability level, t(57) = 3.31, p = 0.003, and the 88% probability level, t(57) = 2.37, p = 0.02. The error bars indicate +/− 1 SEM. ASD, Autism Spectrum Disorder; SEM, standard error of the mean.
