Children with autism spectrum disorder (ASD) show significantly better mathematical abilities and sophisticated strategy use compared with their age-, gender-, and IQ-matched typically developing (TD) peers. (A) Standardized math achievement scores by group. Children with ASD performed better than TD children on the numerical operations subtest of the Wechsler Individual Achievement Test. (B) Discrepancy scores between standardized math measure and full IQ scores by group. Children with ASD displayed a bigger discrepancy score than TD children. (C) Different strategy use in ASD and TD. The groups differed significantly on the percentage of trials in which a decomposition strategy was used. Error bars indicate standard error of the mean. *p < .05. n.s., nonsignificant.
