The present study examined language comprehension in Autism Spectrum Disorder (ASD) in light of monitoring. It was studied whether individuals with ASD monitor their language perception, and whether monitoring during language perception could be modulated with instructions. We presented higher-level (semantic) linguistic violations and lower-level (orthographic) linguistic violations in a free reading condition and in an instructed condition, recording event-related potentials. For control participants, a monitoring response as tapped by the P600 effect was found to semantically and orthographically incorrect input in both conditions. For participants with ASD, however, a monitoring response to semantically implausible input, tapped by the P600, was found only in the instructed condition. For orthographic errors monitoring was observed both in the free reading and in the instructed condition. This suggests that people with ASD are less inclined than typical individuals to monitor their perception of higher-level linguistic input, but that this can be enhanced with instructions.
本研究从监测的角度考察了自闭症谱系障碍（ASD）中的语言理解。研究了 ASD 个体是否监测他们的语言感知，以及在语言感知期间监测是否可以通过指令进行调节。我们在自由阅读条件和指令条件下呈现了更高层次（语义）的语言违规和较低层次（拼写）的语言违规，记录了事件相关电位。对于对照组参与者，发现 P600 效应表明在两种条件下语义和拼写不正确的输入都存在监测反应。然而，对于 ASD 参与者，仅在指令条件下才发现对语义上不合理输入的监测反应，由 P600 触发。对于拼写错误，在自由阅读和指令条件下都观察到了监测。这表明，与典型个体相比，ASD 个体不太倾向于监测他们对更高层次语言输入的感知，但可以通过指令来增强这种监测。
