有限的证据表明，与具有典型语言的同龄人相比，患有发展性语言障碍（DLD）的成年人在处理句子时会考虑不同的信息。本研究的目的是评估两个因素如何影响患有 DLD 的成年人的句子处理：在线存储成本和名词产生的词汇期望。 43 名成年人（其中 21 名患有 DLD）听了逐字呈现的复杂句子，并记录了他们的听力时间。这些句子包括宾语关系从句或句子补语，其在线存储需求有所不同。在典型成年人的句子中，主句主语名词与“that”的共现频率不同。参与者完成了一项跑步任务来评估言语工作记忆能力。混合效应模型发现了句子区域的差异。使用 DLD 的参与者比使用典型语言的参与者更快地处理嵌入的从句动词，而较差的语言能力与更快地处理连词“that”和“which”有关。言语工作记忆能力或典型语言较高的参与者受到名词共现频率的影响，但工作记忆或 DLD 较低的参与者则不受名词共现频率的影响。该结果与先前的发现一致，即言语工作记忆能力会影响影响即时句子处理的信息。那些能力更强的人似乎更容易受到暂时模糊性的影响。与具有典型语言的成年人相比，患有 DLD 的成年人的处理时间对经常与名词同时出现的单词信息不太敏感。这与先前的研究结果一致，表明患有 DLD 的成年人对与动词同时出现的结构和参数的频率不太敏感。
Limited evidence suggests that adults with developmental language disorder (DLD) take different information into account as they process sentences as compared to peers with typical language. The purpose of this study was to evaluate how two factors affect sentence processing in adults with DLD: online storage costs and lexical expectations created by nouns. Forty-three adults, 21 with DLD, listened to complex sentences presented word-by-word, and their listening times were recorded. The sentences included either object relative clauses or sentential complements which differed in online storage demands. The main clause subject nouns differed in co-occurrence frequency with “that” in sentences produced by typical adults. Participants completed a running span task to assess verbal working memory capacity. Mixed effects models found differences by sentence region. Participants with DLD processed embedded clause verbs faster than participants with typical language, and poorer language ability was associated with faster processing of conjunctions “that” and “which.” Participants with greater verbal working memory capacity or typical language were affected by noun co-occurrence frequencies but those with lower working memory or DLD were not. The results align with prior findings that verbal working memory capacity influences what information affects moment-to-moment sentence processing. Those with greater capacity appeared to be more affected by temporary ambiguity. As compared to adults with typical language, processing times of adults with DLD were less sensitive to information on words that frequently co-occur with nouns. This aligns with prior findings suggesting that adults with DLD are less sensitive to the frequency of the structures and arguments that co-occur with verbs.
