Neurobiological correlates of speech production influenced by different emotions

语言研究是一个快速发展和惊人的研究领域。然而，到目前为止，我们对大脑如何协调产生语言的复杂过程以及大脑如何将语言的产生与情感处理等其他过程联系起来知之甚少。该项目将重点研究不同的情感信息对单个单词生成的不同阶段的影响。我们的目标是通过在fMRI测量期间使用不同的任务来表征注意力，感知，认知和情感之间的潜在相互作用，因为这种方法代表了研究几乎每个语言产生水平的大脑过程的绝佳机会。在第一个实验中，受试者将被要求在忽略中性或情感上有价值（积极或消极）的干扰因素的情况下说出一张图片。有了这个任务，我们将能够研究概念、词汇和词汇后的过程。在第二个实验中，我们将使用停止信号任务，受试者将再次说出一张图片，但偶尔必须抑制他们的反应，因为停止信号要么是中性的，要么是积极的，要么是消极的。在这里，我们更愿意进入感知过程和自我监控，这使人类能够几乎没有错误地流利地说话。有了这些数据，我们将更仔细地研究不同的神经关联和网络，它们使我们即使被不同的情绪信息分散注意力，也能流利地说话。总的来说，我们的目的是通过功能神经成像来研究与空间和连通性相关的大脑特征。通过这些结果，我们希望能够阐明异质性结果和高度争议的过程，并根据语言和情感相互作用的潜在神经相关性回答问题。

The investigation of language is a fast growing and amazing research area. However, until now little is known how our brain coordinates the complex processes of producing speech and how our brain connects the production of speech with other processes like emotional processing. The project will focus on the influence of different emotional information on the different stages of single word production. We aim to characterize potential interactions between attention, perception, cognition and emotion by using to different tasks during fMRI measurement as this approach represents a great opportunity to investigate brain processes at nearly every level of language production. In the first experiment, subjects will be asked to name a single picture while ignoring a neutral or emotionally valent (positive or negative) distractors. With this task we will be able to investigate conceptual, lexical and post-lexical processes. In the second experiment, we will use a stop-signal task where subjects will again name a single picture but occasionally have to inhibit their response because of a stop-signal that is either neutral, positive or negative. Here, we rather step into perceptual processes as well as the self-monitoring that enables humans to speak fluently with nearly no errors. With these data, we will have a closer look at different neural correlates and networks that enable us to produce speech fluently even if we are distracted by different emotional information. Overall, we aim to examine the spatial and connectivity related cerebral characteristics by using functional neuroimaging. With the results we hope to shed light on heterogeneous results and highly debated processes as well as answer questions according the underlying neural correlates of the interaction of language and emotion.
