Continuous Goal Dynamics Cognitive Control

项目摘要

To pursue appropriate goals in a world full of distraction, cognitive control processes support the shielding and switching of goals according to current affordances. While cognitive psychology has learned much about cognitive control in the last decade, much less is known about the temporal and spatial dynamics of goal representations. How are goals represented in working memory, how and when do cognitive control processes intervene to stabilize or shift these representations?Until recently, a discrete view of goal dynamics prevailed, implicitly supported by the discrete format of standard tasks and also mirrored in the modelling literature. However, in fact, it is still unresolved if goals could also be represented as continuous and possibly overlapping representations. This could lead to a radical change of the affordances to cognitive control processes, e.g. how to keep goal activations patterns stable or how to switch between overlapping patterns of goals.To investigate continuous goal dynamics in time and representational space, this project will merge the line of cognitive control research with research about working memory dynamics and dynamic neural field modelling. Behavioral experiments will use continuous tasks to enable the study of goal dynamics, supported by modelling, based on dynamic neural field models. By this combination, we will gain insight into goal driven behaviour and cognitive control, constraining future theories of volition, and executive functions.

为了在一个充满分心的世界中追求适当的目标，认知控制过程支持根据当前的承受能力对目标进行屏蔽和切换。虽然认知心理学在过去十年里已经了解了很多关于认知控制的知识，但对目标表征的时间和空间动态的了解要少得多。目标在工作记忆中是如何表现的，认知控制过程是如何以及何时干预以稳定或改变这些表征的？直到最近，一种关于目标动力学的离散观点盛行，这种观点得到了标准任务的离散形式的支持，也反映在建模文献中。然而，事实上，目标是否也可以用连续的、可能重叠的表示来表示，这仍然是一个悬而未决的问题。这可能会导致认知控制过程的承受力发生根本性的变化，例如如何保持目标激活模式的稳定或如何在目标重叠模式之间切换。为了研究时间和表征空间中的连续目标动力学，本项目将把认知控制研究与工作记忆动力学和动态神经场建模研究结合起来。行为实验将使用连续任务，以动态神经场模型为基础，在建模的支持下，实现对目标动力学的研究。通过这种结合，我们将深入了解目标驱动的行为和认知控制，从而约束未来的意志理论和执行功能。
