Numerous studies have shown evidence for a sparse lexicon in speech perception, often in the guise of underspecification, where certain information is omitted in the specification of phonological forms. While previous work has made a good case for underspecifying certain features of single speech sounds, the role of phonological context in underspecification has been overlooked. Contextually-mediated underspecification is particularly relevant to conceptualizations of the lexicon, as it is couched in item-specific (as opposed to phoneme-specific) patterning. In this study, we present behavioral and ERP evidence that surrounding phonological context may trigger underspecified lexical forms, using regular morphophonological alternations in English.
众多研究已为言语感知中存在稀疏词汇表提供了证据，这种情况通常以特征不充分说明的形式出现，即语音形式的说明中某些信息被省略。虽然先前的研究很好地论证了对单个语音的某些特征进行不充分说明，但语音语境在特征不充分说明中的作用却被忽视了。语境介导的特征不充分说明与词汇表的概念化特别相关，因为它基于特定项目（而非特定音素）的模式。在本研究中，我们利用英语中规则的形态音位交替，给出行为学和事件相关电位证据，表明周围的语音语境可能触发特征不充分的词汇形式。
