Dynamic and flexible aspects of language production

本项目旨在研究语言产生的动态和情景方面。该项目有两个主要目标。一个目标是研究语义处理的不同方面，超越经典的范畴关系，如联想主题关系，语义距离，或语义丰富的预期信息，并描述这些语义因素的行为和电生理相关。本研究的第二个目标是探讨词汇激活的动力学如何受到更一般的认知加工机制的影响。特别是，我们探讨了歧义的认知处理模式，由歧义文本的呈现引起的（例如，双关语）影响被试命名同音词图片时不同意义的共激活。显性语言产生过程中的事件相关脑电位将被用来跟踪语音规划过程中语义处理的功能和时间动态。

This project aims to investigate dynamic and situational aspects of language production. The project has two major goals. One goal is to investigate different facets of semantic processing beyond classic categorical relations, such as associative-thematic relations, semantic distance, or the semantic richness of the intended message, and to describe the behavioral and electrophysiological correlates of these semantic factors. The second goal of the planned research is to investigate how the dynamics of lexical activation may be affected by more general cognitive processing mechanisms. In particular, we explore whether a cognitive processing mode of ambiguity, induced by the presentation of ambiguous texts (e.g., puns) affects the co-activation of different meanings when participants name the pictures of homophones. Event-related brain potentials during overt language production will be used to track the functional and temporal dynamics of semantic processing during speech planning.
