The processing speed index (PSI) of the Wechsler intelligence scale for children (WISC-IV) has been found to predict a child's level of academic functioning. The consistently reported PSI weakness in children with autism spectrum disorder (ASD) therefore warrants special assistance and attempts at compensation for the disadvantages associated with these children's low PSI. We investigated the association of PSI scores with age, general cognitive ability [as measured by full-scale IQ (FSIQ)], symptom severity and discrepancy between the WISC-IV indices verbal comprehension (VCI) and perceptual reasoning (PRI) in 101 school children with ASD. The PSI weakness in children with ASD was not related to age, FSIQ, VCI-PRI discrepancy or any of the symptom measures. These findings suggest that school children with ASD independent of their age, level of cognitive ability, VCI-PRI profile and most notably independent of their symptom severity should be entitled to special assistance and compensation in educational settings.

所有年龄、症状严重程度和一般认知能力水平的自闭症谱系障碍儿童都表现出低处理速度指数分数，需要特殊教育援助。

已发现韦氏儿童智力量表 (WISC-IV) 的处理速度指数 (PSI) 可预测儿童的学业功能水平。因此，自闭症谱系障碍 (ASD) 儿童持续报告的 PSI 弱点需要特别援助，并尝试补偿与这些儿童的低 PSI 相关的缺点。我们在 101 所学校调查了 PSI 分数与年龄、一般认知能力 [通过全面智商 (FSIQ) 测量]、症状严重程度以及 WISC-IV 指标语言理解 (VCI) 和知觉推理 (PRI) 之间的差异的关系自闭症儿童。ASD 儿童的 PSI 弱点与年龄、FSIQ、VCI-PRI 差异或任何症状测量无关。这些研究结果表明，患有 ASD 的学童与年龄无关，
