Feature (Un)Binding and Retrieval in Action Discarding

BRAC框架假设，计划一个行动包括对相应行动的感知特征的临时绑定。这种集成的特征表达称为动作文件。这个项目研究如何在动作丢弃中修改动作文件。动作丢弃可以由于不同的原因而发生，例如，当不再需要最初计划的动作时，或者必须在其执行的过程中被扣留，或者在执行时必须终止。这种丢弃可以用不同的方式解释，例如禁止单个动作文件，或一般阻止传出活动，或解绑动作的特征。这些模型对丢弃某个操作如何影响其他功能重叠的操作的性能做出了不同的预测。因此，我们将在实验中测试这些模型，在这些实验中，参与者计划在不同的时间点必须放弃的特定操作。在另一个特征重叠动作中的性能将指示初始动作文件如何通过丢弃而改变。除了评估表现，我们还将记录脑电(EEG)。我们将主要基于时频分解的脑电活动和多变量模式分析，通过分析指示性脑电参数来支持行为证据。总而言之，这个项目将通过观察BRAC核心机制的镜头来观察抑制过程，并通过揭示它们的神经生理学关联来指定BRAC框架。

The BRAC framework assumes that planning an action comprises of the temporary binding of the perceptual features of the corresponding action. Such integrated feature representations are called action files. This project studies how action files are amended in action discarding. Action discarding can occur for different reasons, such as when an initially planned action is no more needed, or must be withheld on its way to execution, or must be terminated while being carried out. Such discarding can be construed in different ways such as inhibition of individual actions files, or general blocking of efferent activities, or as unbinding of the action’s features. These models make different predictions about how discarding a certain action impacts performance of other, feature-overlapping, actions. Consequently, we will test these models in experiments in which participants plan a certain action which has to be discarded at varying points in time. Performance in another feature-overlapping action will indicate how the initial action file has become altered by discarding. On top of assessing performance we will record electroencephalogram (EEG). We will bolster behavioural evidence by analysing indicative EEG parameters primarily based on time-frequency decomposed EEG activity and multivariate pattern analyses. Altogether this project will specify the BRAC framework by looking at inhibitory processes through the lens of BRACs core mechanisms and by revealing their neurophysiological correlates.
