Language production in shared task settings

通常，人们在社交互动的背景下说话。然而，令人惊讶的是，很少有人知道语言产生的神经认知过程是如何被社会互动塑造的。利用语言生产中的一个行之有效的效果，我们调查的程度时，命名一系列的图片与任务的合作伙伴所经历的语义干扰。在单个主题设置中，命名延迟随着给定语义类别的每个新图片而增加，即所谓的累积语义干扰（例如，霍华德等人，2006年）。最近，已经证明，命名laveli不仅会增加对说话者自己先前命名语义相关图片的响应，而且还会响应他们的任务伙伴命名图片（Hoedemaker，Ernst，Meyer，& Belke，2017; Kuhlen & Abdel Rahman，2017）。这表明，任务合作伙伴代表对方的行动，并代表他们的合作伙伴参与词汇化。基于这些发现，我们想具体说明（1）合作伙伴引发的语义干扰背后的机制，（2）代表合作伙伴的词汇通达在多大程度上反映了合作伙伴的任务（而不仅仅是自己的任务）的具体性质，以及（3）合作伙伴引发的词汇通达是否取决于任务合作伙伴或任务设置的特点。最后，我们想了解（4）我们在联合图片命名框架内的发现如何扩展到对话。我们希望通过一系列的实验，根据行为观察lavelion在联合图片命名和电生理，事件相关的记录这些问题的见解。从这里提出的项目的结果将有助于更好地了解语言生产过程中的社会互动，以及加深我们的理解如何灵活的语义系统适应社会背景。

Typically, people speak in the context of social interaction. Yet, surprisingly little is known about how the neuro-cognitive processes of language production are shaped by social interaction. Drawing upon a well-established effect in language production we investigate the degree of semantic interference experienced when naming a sequence of pictures together with a task partner. In single subject settings, naming latencies increase with each new picture of a given semantic category, so-called cumulative semantic interference (e.g., Howard et al., 2006). Recently, it has been demonstrated that naming latencies not only increase in response to speakers’ own prior naming of semantically related pictures, but also in response to their task partner naming pictures (Hoedemaker, Ernst, Meyer, & Belke, 2017; Kuhlen & Abdel Rahman, 2017). This suggests that task partners represent each other’s actions and engage in lexicalization on behalf of their partner. Based on these findings we want to specify (1) the mechanism behind partner-elicited semantic interference, (2) the extent to which lexical access on behalf of the partner reflects the specific nature of the partner’s task (and not just the own task), and (3) whether partner-elicited lexical access depends on characteristics of the task partner or the task setting. Finally, we want to understand (4) how our findings within the framework of joint picture naming scale up to conversation. We expect insights into these questions through a series of experiments based on behavioral observations of latencies during joint picture naming and electrophysiological, event-related recordings. The results from the here proposed project will contribute to a better understanding of language production during social interaction as well as deepen our understanding of how flexibly the semantic system adapts to social context.
