最近的许多心理和神经语言学工作旨在通过研究语义不匹配的处理来阐明句子意义的构成机制。语义构成理论的一个有争议的例子是诸如“小丑跳了十分钟”这样的表达，其中守时动词的体属性与持续修饰语的体属性发生冲突。有人建议此类句子涉及强制操作，将动词的准时含义转变为迭代含义。然而，针对这一假设的加工研究产生了不同的结果。在这项研究中，我们测试了如何通过自定进度阅读和脑磁图解决方面不匹配的四种假设。使用一组以准时为规范的动词，我们确定了不匹配的直接行为成本。发现这种处理的神经相关性与先前与补体强制的解决有关的中线前额叶区域的效果相匹配。我们还发现了对右侧额叶和颞叶部位的早期影响。我们认为，在目前文献中的代表性假设中，这些数据与一种说法最为一致，即方面不匹配最初涉及异常含义的构成，随后通过强制修复。 (C) 2008 Elsevier Inc. 保留所有权利。
Much recent psycho- and neuro-linguistic work has aimed to elucidate the mechanisms by which sentence meanings are composed by investigating the processing of semantic mismatch. One controversial case for theories of semantic composition is expressions such as the clown jumped for ten minutes, in which the aspectual properties of a punctual verb clash with those of a durative modifier. Such sentences have been proposed to involve a coercion operation which shifts the punctual meaning of the verb to an iterative one. However, processing studies addressing this hypothesis have yielded mixed results. In this study, we tested four hypotheses of how aspectual mismatch is resolved with self-paced reading and magnetoencephalography. Using a set of verbs normed for punctuality, we identified an immediate behavioral cost of mismatch. The neural correlates of this processing were found to match effects in midline prefrontal regions previously implicated in the resolution of complement coercion. We also identified earlier effects in right-lateral frontal and temporal sites. We suggest that of the representational hypotheses currently in the literature, these data are most consistent with an account where aspectual mismatch initially involves the composition of an anomalous meaning that is later repaired via coercion.
