成功的目标导向行为通常需要持续的感觉处理，同时在工作记忆 (WM) 中维护与任务相关的信息。尽管已知 WM 和感知会相互作用，但人们对如何控制它们的相互作用却知之甚少。在这里，我们测试了这样的假设：WM 感知交互涉及两种不同的控制模式——主动和被动——其方式类似于经典的冲突适应任务（例如斯特鲁普、侧翼和西蒙）。参与者执行了延迟的方向回忆 WM 任务，加上延迟期间发生的独立视觉方向辨别任务，并且操纵的任务之间的方向一致。主动控制体现在任务绩效对先前试验一致性的敏感性（即格拉顿效应）。在不一致的判别所产生的排斥性序列依赖性中观察到反应性控制。从数量上讲，这些效应是通过基于强化学习的模型的参数来解释的，该模型跟踪控制需求的试验间波动：通过阶段控制预测误差（控制 PE）进行反应性控制，以及通过控制 PE 更新每次试验的预测冲突的紧张水平进行主动控制。因此，WM 感知交互可能由控制其他认知领域冲突的相同机制（例如响应选择）来控制。
Successful goal-directed behavior often requires continuous sensory processing while simultaneously maintaining task-related information in working memory (WM). Although WM and perception are known to interact, little is known about how their interactions are controlled. Here, we tested the hypothesis that WM perception interactions engage two distinct modes of control – proactive and reactive – in a manner similar to classic conflict-adaptation tasks (e.g. Stroop, flanker, and Simon). Participants performed a delayed recall-of-orientation WM task, plus a standalone visual discrimination-of-orientation task the occurred during the delay period, and with the congruity in orientation between the tasks manipulated. Proactive control was seen in the sensitivity of task performance to the previous trial's congruity (i.e. a Gratton effect). Reactive control was observed in a repulsive serial-dependence produced by incongruent discriminanda. Quantitatively, these effects were explained by parameters from a reinforcement learning-based model that tracks trial-to-trial fluctuations in control demand: reactive control by a phasic control prediction error (control PE), and proactive control by a tonic level of predicted conflict updated each trial by the control PE. Thus, WM-perception interactions may be controlled by the same mechanisms that govern conflict in other domains of cognition, such as response selection.
