This study examined the Argument Structure Complexity Hypothesis (ASCH, [J. Neuroling. 16 (2003) 151]), by investigating agrammatic aphasic comprehension and elicited production of two types of intransitive verbs (i.e. unergatives and unaccusatives) in sentence contexts. The ASCH attributes production difficulty frequently observed in agrammatic aphasia to the argument structure entries of verbs, stating that verbs with a more complex argument structure (in terms of the number and type of arguments) are more difficult for agrammatic aphasic patients to produce than those with a less complex argument structure. Results showed that eight agrammatic aphasic subjects had production difficulty with unaccusative verb sentences, as compared to unergatives, in the face of near-normal comprehension of both sentence types. These findings support the ASCH that predicts production difficulty with sentences involving unaccusatives with more complex argument structures. Error patterns observed also indicated successful lemma access in that the full array of verb argument structures were produced during sentence attempts, suggesting that complex argument structures hinder appropriate processing after the lemma level.

非宾格动词在句子语境中的语法失语产生与理解

本研究通过调查语法失语理解和句子上下文中两种不及物动词（即非作格动词和非宾格动词）的引出产生，检验了论据结构复杂性假设 (ASCH, [J. Neuroling. 16 (2003) 151])。ASCH 将语法性失语症中常见的产生困难归因于动词的论元结构条目，指出具有更复杂的论元结构（在论据的数量和类型方面）的动词对于语法失语症患者来说比具有一个不太复杂的论证结构。结果表明，在对两种句子类型的理解接近正常的情况下，八位语法失语症受试者在使用非宾格动词句时比非作格更难。这些发现支持 ASCH 预测生产难度的句子涉及更复杂的论据结构的非宾格。观察到的错误模式也表明成功的引理访问，因为在句子尝试期间产生了完整的动词参数结构数组，这表明复杂的参数结构阻碍了引理级别之后的适当处理。
