Cognitive control is assumed to establish context-specific representations of tasks ( task sets ) in task switching. Current theories assume a task-set decay process after task performance and prior to performing the subsequent task. However, this decay process has remained functionally underspecified. The aim of the present project is to specify the functional target of decay in task switching. The first hypothesis is that decay refers to the response set , which represents the cognitive meaning of the responses according to the current task goal. The second hypothesis is that the process of response-set biasing continues even after response execution, so that the onset of decay is related to the completion of response-set biasing rather than to the completion of the overt response. Finally, it is hypothesized that response- set biasing in task switching is related to reinforcement learning based on a generic action monitoring system. The project aims to provide empirical evidence for these hypotheses concerning functionally specified cognitive mechanisms. On the theoretical level, this project also aims to connect theories of response set in task switching to theories of action (or error ) monitoring in single-task situations.

认知控制被认为是建立任务（任务集）在任务切换的特定语境的表征。目前的理论假设一个任务集衰减过程后，任务的执行和执行之前的后续任务。然而，这一衰变过程在功能上仍然没有得到充分说明。本项目的目的是指定的功能目标的衰减任务切换。第一个假设是，衰减是指响应集，它代表了根据当前任务目标的响应的认知意义。第二个假设是，响应集偏置的过程甚至在响应执行之后仍在继续，因此衰减的开始与响应集偏置的完成有关，而不是与公开响应的完成有关。最后，假设任务切换中的反应集偏差与基于通用动作监控系统的强化学习有关。该项目旨在为这些关于功能特定的认知机制的假设提供经验证据。在理论层面上，本项目还旨在将任务转换中的反应集理论与单任务情况下的行动（或错误）监控理论联系起来。
