这项工作评估了231人（79名原发性进行性失语症[PPA]患者和152名健康说话者）的样本中语言产生过程中单词选择和句法选择之间长期争论的关系。我们首先提供了一个表征的句法复杂性的基础上的频率的句法规则，它允许直接比较的句法和词汇的复杂性。然后，我们提供了收敛的证据，在图片描述的话语规划，这可能反映了语言生产的一个基本属性的句法-词汇复杂性权衡。口语表达包括选择和组合单词和句法结构来传达信息。在这里，我们探讨这一过程，通过分析自然语言生产的个人与原发性进行性失语症（PPA）和健康的人。基于先前的神经心理学观察，我们假设，患者谁有困难产生复杂的句法可能会选择语义丰富的话，使他们的意思清楚，而患者词汇语义缺陷可能会选择更复杂的句法。为了评估这一假设，我们首先介绍了一种基于频率的方法来表征自然产生的话语的句法复杂性。然后，我们表明，词汇和句法的复杂性，测量其频率，是负相关的一个大的（n = 79）PPA人口。然后，我们表明，这种句法-词汇权衡也存在于健康的扬声器（n = 99）参加图片描述任务的话语，这表明它可能是一个一般属性的过程中，人类把思想变成语音。
This work evaluates the long-debated relationship between word selection and syntax selection during language production in a sample of 231 individuals (79 patients with primary progressive aphasia [PPA] and 152 healthy speakers). We first provide a characterization of syntactic complexity based on the frequency of the syntactic rules, which allows for the direct comparison of syntactic and lexical complexities. We then provide converging evidence for a syntax–lexicon complexity trade-off in utterance planning in picture description which might reflect a basic property of language production. Spoken language production involves selecting and assembling words and syntactic structures to convey one’s message. Here we probe this process by analyzing natural language productions of individuals with primary progressive aphasia (PPA) and healthy individuals. Based on prior neuropsychological observations, we hypothesize that patients who have difficulty producing complex syntax might choose semantically richer words to make their meaning clear, whereas patients with lexicosemantic deficits may choose more complex syntax. To evaluate this hypothesis, we first introduce a frequency-based method for characterizing the syntactic complexity of naturally produced utterances. We then show that lexical and syntactic complexity, as measured by their frequencies, are negatively correlated in a large (n = 79) PPA population. We then show that this syntax–lexicon trade-off is also present in the utterances of healthy speakers (n = 99) taking part in a picture description task, suggesting that it may be a general property of the process by which humans turn thoughts into speech.
