Two theoretical viewpoints provide different explanations about how people extract statistical regularities from input to assess the felicity of verb usage in a sentence. The lexical approach emphasizes the role of verb frequency in determining a verb’s distributional bias within a sentence, whereas the entrenchment hypothesis highlights the conjoined roles of the frequency information from both a verb and an argument structure construction. The present study tests these accounts by investigating Korean speakers’ interpretation of two dative patterns in Korean (Dative–Accusative and Accusative–Accusative). Through the analysis of a large-scale corpus, we calculated the frequency of each dative pattern as well as the frequency of dative verbs occurring therein. Using this information, we conducted an acceptability judgment task with Korean speakers by manipulating the dative type and the verb frequency. The results showed that the speakers’ acceptability rating behavior was affected by the interaction between the verb and construction frequency such that highly entrenched verb–construction combinations were evaluated to be more acceptable. Our finding supports the entrenchment hypothesis that emphasizes the conjoined roles of usage frequency of verbs and constructions in sentence comprehension.

动词和结构频率对句子理解的影响

关于人们如何从输入中提取统计规律以评估句子中动词使用的恰当性，两种理论观点提供了不同的解释。词汇方法强调动词频率在确定动词在句子中的分布偏差中的作用，而防御假说则强调来自动词和论元结构构造的频率信息的联合作用。本研究通过调查说韩语的人对韩语中两种与格模式（宾格-宾格和宾格-宾格）的解释来检验这些叙述。通过对大规模语料库的分析，我们计算了每个与格模式的频率以及与格动词在其中出现的频率。使用这些信息，我们通过操纵与格类型和动词频率对说韩语的人进行了可接受性判断任务。结果表明，说话者的可接受性评级行为受到动词和结构频率之间相互作用的影响，因此高度根深蒂固的动词-结构组合被评估为更容易接受。我们的发现支持强化假设，该假设强调动词的使用频率和结构在句子理解中的联合作用。
