认知控制过程使我们能够在对我们的认知系统提出不断变化的要求的世界中灵活行动。冲突任务尤其是一致性序列效应被认为是研究认知控制的有效工具。然而，在过去的十年中，出现了一个争议是否一致序列效应确实是一个有效的措施的认知控制过程。这场争论导致了越来越复杂的范式的发展，涉及众多的，错综复杂的设计实验条件，其目的是排除低层次的，联想的学习机制，如功能绑定作为一种替代解释的一致性序列效应的出现。在这里，我们试图超越这种全有或全无的思维，通过调查的假设，即认知控制过程以及功能绑定机制发生在同一任务的试验。基于理论上的双路线模型的冲突下的行为，我们表明，这两类认知机制应影响行为在不同的点的决策过程。通过比较这些预测，从一个适应西蒙任务的连续鼠标运动，我们发现的证据表明，控制过程和功能绑定机制确实共存的任务，但它们遵循不同的时间模式。我们认为，这种动态的认知加工方法开辟了新的途径来调查的多样性共存的过程，有助于选择的行为。
Cognitive control processes enable us to act flexibly in a world posing ever-changing demands on our cognitive system. To study cognitive control, conflict tasks and especially congruency sequence effects have been regarded as a fruitful tool. However, for the last decade a dispute has arisen whether or not congruency sequence effects are indeed a valid measure of cognitive control processes. This debate has led to the development of increasingly complex paradigms involving numerous, intricately designed experimental conditions which are aimed at excluding low-level, associative learning mechanisms like feature binding as an alternative explanation for the emergence of congruency sequence effects. Here, we try to go beyond this all-or-nothing thinking by investigating the assumption that both cognitive control processes as well as feature binding mechanisms occur within trials of the same task. Based on a theoretical dual-route-model of behavior under conflict, we show that both classes of cognitive mechanisms should affect behavior at different points of the decision process. By comparing these predictions to continuous mouse movements from an adapted Simon task, we find evidence that control processes and feature binding mechanisms do indeed coexist within the task but that they follow distinct timing patterns. We argue that this dynamic approach to cognitive processing opens up new ways to investigate the diversity of co-existing processes that contribute to the selection of behavior.
