与传统的感知方法不同，“主动感知”意味着感知处理并不简单地导致行动，而是本身受到与行动相关的处理的影响-在与环境的持续交换中，涉及对环境中统计信息的适应（“先验”）。在过去的二十年里，知觉的概念化有了一些新的发展（我们对此做出了重大贡献）：（i）行动对知觉的因果影响，（ii）预测编码，（iii）主体的“情境性”，以及（iv）给定外部世界状态的行动（替代）的“效用”。拟议的多学科DFG研究单位“主动感知”（RU-AP）的主旨是将这些迄今为止在很大程度上被单独对待的发展整合到一个连贯统一的框架中。在这一框架内要进行的特定工作链涵盖了整个感知-认知-行动循环，特别是：视觉处理中的预测性、基于记忆的效应（例如，维度加权、上下文提示、有意绑定;注意力的动态分配和预期感受场重映射，在扫视眼球运动和手动（例如，抓取）动作;多模态感知和动作;以及预测感知处理的数学建模。N=11个独立的项目是“真正的”跨学科的设计，与实验P的贡献，生物学P.，发展P.，神经-P.，神经病学，神经精神病学和数学，并使用各种神经科学技术，除了行为方法：脑电图，功能磁共振成像，经颅磁刺激，神经心理学评估-从而促进神经科学和认知观点在“主动感知”研究中的整合。计划中的研究还包括关注正在考虑的功能的发展（正常与病理性衰老），以及神经病学/精神病学高级诊断的应用领域以及技术应用（例如，BCI，社交机器人）。

In contrast to traditional approaches to perception,"Active Perception" implies that perceptual processing does not simply lead to action, but is itself influenced by action-related processing - in a continuous exchange with the environment, involving adaptation to the statistical regularities in the environment ("priors"). In the past two decades, there have been several new developments in the conceptualization of perception (to which we have contributed significantly): (i) causal influence of action on perception, (ii) predictive coding, (iii) "situatedness" of the agent, and (iv) "utility" of an action (alternative) given the state of the external world. The thrust of the proposed, multidisciplinary DFG research unit "Active Perception" (RU-AP) is to integrate these developments, which have hitherto been treated largely separately, into a coherent, unifying framework. Particular strands of work to be pursued within this framework encompass the whole perception-cognition-action loop, in particular: predictive, memory-based effects in visual processing (e.g., dimension weighting, contextual cueing, intentional binding; dynamic allocation of attention, and anticipatory receptive-field re-mapping, prior to saccadic eye movements and manual (e.g., grasping) actions; multi-modal perception and action; and the mathematical modelling of predictive perceptual processing. The N=11 individual projects are "truly" interdisciplinary by design, with contributions from Experimental P., Biological P., Developmental P., Neuro-P., Neurology, Neuropsychiatry, and Mathematics, and use a variety of neuroscience techniques, besides behavioral approaches: EEG, fMRI, TMS, neuropsychological assessment - thus fostering an integration of the neuroscientic and cognitive perspectives in research on "Active Perception". The planned research also includes foci on developmental (normal vs. pathological aging) of the functions under consideration, with areas of application in advanced diagnostics in neurology / psychiatry as well as technical applications (e.g., BCI, social robotics).
