Recent studies have documented frequency effects for word n-grams, independently of word unigram frequency. Further studies have revealed constructional prototype effects, both at the word level as well as for phrases. The present speech production study investigates the time course of these effects for the production of prepositional phrases in English, using event related potentials (ERPs). For word frequency, oscillations in the theta range emerged. By contrast, phrase frequency showed a persistent effect over time. Furthermore, independent effects with different temporal and topographical signatures characterized phrasal prototypicality. In a simulation study we demonstrate that naive discrimination learning provides an alternative account of the data that is as least as powerful as a standard lexical predictor analysis. The implications of the current findings for models of language processing are discussed. (PsycINFO Database Record
近期研究记录了词元组的频率效应，与单词单字频率无关。进一步的研究揭示了构式原型效应，在单词层面以及短语层面均有体现。本言语产生研究使用事件相关电位（ERP）来探究这些效应在英语介词短语产生过程中的时间进程。对于单词频率，出现了θ频段的振荡。相比之下，短语频率随时间呈现出持续效应。此外，具有不同时间和地形特征的独立效应表征了短语原型性。在一项模拟研究中，我们证明朴素辨别学习为数据提供了一种替代解释，其效力至少与标准词汇预测分析相当。讨论了当前研究结果对语言处理模型的启示。（《心理学文摘数据库记录》
