关于英语动词的规则和不规则过去时形式的表示和处理的理论对于它们是否应该被视为一种统一现象(例如,两者都受规则管辖,或两者都由联结主义网络生成),或作为两种不同类型的语言实体(例如,由语法规则形成的规则,存储在词汇记忆中的不规则)存在分歧。在本文中,我们提供了来自正电子发射断层扫描研究的数据,其中受试者被要求说出规则、不规则和随机数词干的过去时态形式。我们发现,在规则任务和不规则任务中,皮质激活的数量和区域存在很大差异,并且在产生过去时态时的反应时间也显着不同。我们将我们的发现解释为支持语法/词汇理论,并讨论我们的结果对一般语言理论的影响。*
Theories about the representation and processing of regular and irregular past tense forms of verbs in English have disagreed as to whether they should be treated as a unified phenomenon (e.g. both rule-governed, or both generated by a connectionist net), or as two distinct types of linguistic entities (e.g. regulars formed by rules of the grammar, irregulars stored in lexical memory). In this article we present data from a positron emission tomographic study in which subjects were asked to produce the past tense forms of regular, irregular, and nonce stems. We find very different amounts and areas of cortical activation in the regular and irregular tasks, as well as significantly different reaction times in producing the past tenses. We interpret our findings as supporting the grammar/lexicon theories, and discuss the implications of our results for general linguistic theory.*
