Task-set decay, response set, and action monitoring

假设认知控制在任务切换中建立任务（任务集）的上下文特定表示。目前的理论假设任务集衰减过程在任务执行之后和执行后续任务之前。然而，这种衰变过程在功能上仍未得到充分说明。本项目的目的是明确任务切换中衰减的功能目标。第一个假设是衰变指的是响应集，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，即使在响应执行后，响应集偏置过程仍在继续，因此衰减的开始与响应集偏置的完成有关，而不是与显性反应的完成有关。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指定认知机制的假设提供经验证据。在理论层面，本项目还旨在将任务切换中的反应集理论与单任务情境中的行为（或错误）监测理论联系起来。

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.
