Skilled sentence production involves distinct stages of message conceptualization (deciding what to talk about) and message formulation (deciding how to talk about it). Eye-movement paradigms provide a mechanism for observing how speakers accomplish these aspects of production in real time. These methods have recently been applied to children with autism spectrum disorder (ASD) and specific language impairment (LI) in an effort to reveal qualitative differences between groups in sentence production processes. Findings support a multiple-deficit account in which language production is influenced not only by lexical and syntactic constraints, but also by variation in attention control, inhibition and social competence. Thus, children with ASD are especially vulnerable to atypical patterns of visual inspection and verbal utterance. The potential to influence attentional focus and prime appropriate language structures are considered as a mechanism for facilitating language adaptation and learning.
熟练的句子生成涉及信息概念化（决定要说什么）和信息表达（决定如何表达）的不同阶段。眼动范式提供了一种实时观察说话者如何完成这些生成方面的机制。这些方法最近已应用于自闭症谱系障碍（ASD）和特定语言障碍（LI）儿童，以揭示言语产生过程中组间的定性差异。研究结果支持一种多重缺陷理论，即语言生成不仅受到词汇和句法限制的影响，还受到注意力控制、抑制和社会能力变化的影响。因此，患有 ASD 的儿童特别容易出现异常的视觉检查和口头表达模式。影响注意力焦点并提示适当语言结构的潜力被认为是促进语言适应和学习的一种机制。
