当孩子们实时解释口语时，语言信息会推动视觉注意力快速转移到视觉世界中的物体。这种语言与视觉的互动可以洞察儿童语言理解能力的发展效率。但是，当语言信号和视觉世界都通过视觉通道处理时，语言如何影响视觉注意力呢？在这里，我们测量了 29 名以美国手语为母语的学习儿童（16-53 个月，16 名聋人，13 名听力者）和 16 名流利的聋人成年手语者实时理解视觉手语语言（美国手语 (ASL)）时的眼球运动。所有手语者都表现出快速、渐进的语言理解能力，倾向于在手语抵消之前开始眼球运动。失聪者和听力正常的 ASL 学习者表现出相似的凝视模式，这表明 ASL 处理过程中眼球运动的即时动态是由实时处理视觉语言的限制决定的，而不是由日常生活中对听觉信息的差异获取决定的。最后，儿童 ASL 处理的变化与年龄和词汇量呈正相关。因此，尽管在单一模态中存在注意力竞争，但 ASL 理解过程中视觉注视的时间和准确性反映了信息处理技能，无论语言模态如何，信息处理技能都是语言习得的基础。
When children interpret spoken language in real time, linguistic information drives rapid shifts in visual attention to objects in the visual world. This language-vision interaction can provide insights into children’s developing efficiency in language comprehension. But how does language influence visual attention when the linguistic signal and the visual world are both processed via the visual channel? Here, we measured eye movements during real-time comprehension of a visual-manual language, American Sign Language (ASL), by 29 native ASL-learning children (16–53 mos, 16 deaf, 13 hearing) and 16 fluent deaf adult signers. All signers showed evidence of rapid, incremental language comprehension, tending to initiate an eye movement before sign offset. Deaf and hearing ASL-learners showed similar gaze patterns, suggesting that the in-the-moment dynamics of eye movements during ASL processing are shaped by the constraints of processing a visual language in real time and not by differential access to auditory information in day-to-day life. Finally, variation in children’s ASL processing was positively correlated with age and vocabulary size. Thus, despite competition for attention within a single modality, the timing and accuracy of visual fixations during ASL comprehension reflect information processing skills that are fundamental for language acquisition regardless of language modality.
