The N2 component and the ERN/Ne are regarded as indicators of conflict-monitoring (Yeung & Cohen, 2006). In previous studies a modulation of the N2 component and the ERN/Ne by means of anxiety-related treatment conditions as well as correlations of the N2 component and the ERN/Ne with trait-anxiety were found. However, the modulation of the N2 component and the ERN/Ne was generally demonstrated in separate studies so that it remains unknown whether the (quasi-) experimental treatment conditions that allow for a modulation of the N2 component would also lead to a modulation of the ERN/Ne. It remains also unknown whether conditions that allow for a modulation of the ERN/Ne would also lead to a modulation of the N2 component. Therefore, the intended project investigates whether a mutual generalization of the effects of anxiety-related manipulations on the N2 component and the ERN/Ne is possible. Moreover, Yeung and Cohen (2006) assumed that the ERN/Ne is primarily determined by relevant stimuli whereas the N2 component depends primarily on stimuli that are irrelevant for the task. Therefore, Study 1 of the intended project is based on an anxiety-related manipulation that does induce processing of primarily relevant stimuli. The manipu-lation consists of a misattribution of the anxiety and tension that co-occurs with errors of commission to a beverage that is believed to produce corresponding side effects. In contrast, in Study 2 an anxiety-related manipulation based on processing of irrelevant stimuli is applied. The irrelevant stimuli are faces (fearful vs. neutral) as well as aversive verbal-monetary feedback. The manipulation of irrelevant stimuli is expected to have larger effects on the N2 components than on the ERN/Ne. In both studies larger effects are expected for participants with high trait-anxiety when compared to participants with low trait-anxiety. Moreover, it is expected that the correlation of the ERN/Ne with the N2 component depends on trait-anxiety and on the anxiety-related treatment conditions. Overall, the intended project aims at an investigation and further understanding of the similarities of the N2 component and the ERN/Ne in the context of conflict-monitoring. This might lead to a confirmation and further specification of existing models of conflict-monitoring. Furthermore, it is investigated to what degree the similarities of the N2 component and the ERN/Ne depend on trait-anxiety. The dependence of the similarity of the N2 component and the ERN/Ne on trait-anxiety is an indicator of the relevance of trait-anxiety for conflict-monitoring.

N2部分和ERN/Ne被视为冲突监测指标（Yeung和Cohen，2006年）。在以往的研究中，通过焦虑相关的治疗条件以及N2成分和ERN/Ne与特质焦虑的相关性，发现了N2成分和ERN/Ne的调节。N2分量和ERN/Ne的调制通常在单独的研究中得到证实，因此仍然不知道（准）允许调节N2组分的实验处理条件也将导致ERN/Ne的调节。还不知道允许调节ERN/Ne的条件是否也会导致N2组分的调节。因此，本课题研究焦虑相关的操作对N2分量和ERN/Ne的影响是否可能相互概括。此外，Yeung和Cohen（2006）假设ERN/Ne主要由相关刺激决定，而N2成分主要取决于与任务无关的刺激。因此，研究1的预期项目是基于焦虑相关的操纵，诱导处理主要相关的刺激。这种操纵包括对焦虑和紧张的错误归因，这些焦虑和紧张与错误的委托一起发生在被认为会产生相应副作用的饮料上。与此相反，在研究2焦虑相关的操纵的基础上处理无关的刺激。无关的刺激是面孔（恐惧与中性）以及令人厌恶的语言-金钱反馈。不相关刺激的操纵，预计有更大的影响N2组件比ERN/Ne。在这两项研究中，与低特质焦虑的参与者相比，高特质焦虑的参与者预期会有更大的影响。此外，预计ERN/Ne与N2分量的相关性取决于特质焦虑和焦虑相关的治疗条件。总的来说，计划中的项目旨在调查和进一步了解N2部分与紧急反应网络/Ne在冲突监测方面的相似之处。这可能导致确认和进一步具体说明现有的冲突监测模式。此外，它是调查在多大程度上的N2成分和ERN/Ne的相似性依赖于特质焦虑。N2分量和ERN/Ne的相似性对特质焦虑的依赖性是特质焦虑与冲突监控相关性的指标。
