Exploring the scope and limits of incremental learning in word production - Evidence from picture-word interference and blocked-cyclic naming experiments

在过去的几年里，词汇加工的实验研究和计算模型一直是言语产生研究的重点。尽管有令人信服的证据表明，产生话语的语境对词汇选择，即说话人实际使用的词汇的选择有很大的影响，但关于语境是否也影响到前面的词汇激活过程，我们知之甚少。目前的研究方案将侧重于这一问题。基于指称交际研究的结果，它将侧重于目标话语之前的语言语境的影响，这些影响是由说话人本人或对话伙伴产生的。特别是，我们将探索，这些语言语境施加的限制是否可以阻止对词汇替代的处理，这将导致局部不恰当的话语。该研究计划将利用在指称交际研究背景下发展起来的范式，从而弥合心理语言学中两个独立的研究传统之间的鸿沟：一方面是探索指称交际的指导原则，另一方面是对概念词汇过程的计时分析。我们的发现将有助于更深入地理解和更全面地模拟语境中说话的认知过程及其灵活性。

In the past years, the experimental investigation and computational modelling of lexical processing was in the focus of speech production research. Although there is there is compelling evidence that the context, in which an utterance is produced, has a strong influence on lexical selection, i.e. the selection of words actually used by a speaker, little is known about whether the context also affects the preceding lexical activation processes. The present research programme will focus on this question. Based on findings from referential communication studies, it will focus on effects from linguistic contexts which precede a target utterance and which are produced by either the speaker herself/himself or a dialogue partner. In particular we will explore, whether constraints imposed by these linguistic contexts can prevent the processing of lexical alternatives which would result in locally inappropriate utterances. The research program will make use of paradigms developed in the context of referential communication studies and will thus bridge the cleft between two - for most parts - independent research traditions in psycholinguistics: the exploration of principles guiding referential communication on the one hand and the chronometric analysis of conceptual-lexical processes on the other. Our finding shall contribute to a deeper understanding and more comprehensive modelling of the cognitive processes underlying speaking in context and their flexibility.
