It can be challenging to accurately assess speech and language processing in preverbal or minimally verbal individuals with neurodevelopmental disabilities (NDD) using standardized behavioral tools. Event-related potential and eye tracking methods offer novel means to objectively document receptive language processing without requiring purposeful behavioral responses. Working around many of the cognitive, motor, or social difficulties in NDDs, these tools allow for minimally invasive, passive assessment of language processing and generate continuous scores that may have utility as biomarkers of individual differences and indicators of treatment effectiveness. Researchers should consider including physiological measures in assessment batteries to allow for more precise capture of language processing in individuals for whom it may not behaviorally apparent.

神经发育障碍中言语和语言加工的心理生理和眼动标记：难测人群的新选择。

使用标准化的行为工具来准确评估具有神经发育障碍（NDD）的言语或极少言语个体的言语和语言处理能力可能是具有挑战性的。事件相关的电位和眼睛跟踪方法提供了新颖的方法，可以客观地记录接受语言的处理，而无需有目的的行为响应。这些工具可解决NDD中的许多认知，运动或社会困难，可对语言处理进行微创，被动评估，并生成连续的评分，这些评分可作为个体差异的生物标志物和治疗效果的指标。
