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.

神经发育障碍中语音和语言处理的心理生理和眼球追踪标记：难以测试人群的新选择。

使用标准化行为工具准确评估具有神经发育障碍 (NDD) 的语言前或最低限度语言个体的语音和语言处理可能具有挑战性。事件相关电位和眼动追踪方法提供了一种新颖的方法来客观地记录接受性语言处理，而不需要有目的的行为反应。这些工具解决了 NDD 中的许多认知、运动或社会困难，允许对语言处理进行微创、被动评估，并生成连续分数，这些分数可能用作个体差异的生物标志物和治疗效果的指标。
