本研究使用两个英语前缀“in-”/“im-”和“un-”来考察变异模式与言语感知之间的关系。在自然语言中，“in-”由于潜在的语音同化过程而变化，而“un-”则表现为表层变化的模式，先于唇词干进行同化。在GO/NO-GO词汇判断实验中，受试者被呈现了一组发音错误的刺激，其中鼻音前缀被改变(用[m]替换[n]，或者反之亦然)，除了没有改变前缀的真实单词。前缀之间在对未改变的单词的反应中没有发现显著的差异。在发音错误的项目中，对“un-”形式的反应比对“in-”形式的反应更快、更准确，尽管在唇形语境中，显著的交互作用减轻了这种影响。这些结果表明，变化模式的规律性对单词的词汇规范有影响，并反对激进的规范不足的解释，这些解释主张最大限度地稀疏词汇。
This study examines the relationship between patterns of variation and speech perception using two English prefixes: “in-”/“im-” and “un-”. In natural speech, “in-” varies due to an underlying process of phonological assimilation, while “un-” shows a pattern of surface variation, assimilating before labial stems. In a go/no-go lexical decision experiment, subjects were presented a set of “mispronounced” stimuli in which the prefix nasal was altered (replacing [n] with [m], or vice versa), in addition to real words with unaltered prefixes. No significant differences between prefixes were found in responses to unaltered words. In mispronounced items, responses to “un-” forms were faster and more accurate than to “in-” forms, although a significant interaction mitigated this effect in labial contexts. These results suggest the regularity of variation patterns has consequences for the lexical specification of words, and argues against radical underspecification accounts which argue for a maximally sparse lexicon.
