与传统的感知方法不同，“主动感知”意味着感知处理不是简单地导致行动，而是本身受到与行动有关的处理的影响--在与环境的持续交流中，涉及适应环境中的统计规律(“先验”)。在过去的二十年里，知觉的概念化有了几个新的发展(我们对此做出了重大贡献)：(I)行动对知觉的因果影响，(Ii)预测性编码，(Iii)动因的“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)的主旨是将迄今为止基本上分开处理的这些发展整合到一个连贯的、统一的框架中。在这一框架内要进行的具体工作包括整个知觉-认知-行动环路，特别是：视觉加工中基于记忆的预测性效应(例如，维度加权、上下文线索、有意绑定；在扫视眼球运动和手动(例如，抓取)动作之前的注意力的动态分配和预期接受场重新映射；多模式知觉和行动；以及预测性知觉处理的数学模型。N=11个个人项目在设计上“真正”是跨学科的，包括实验P、生物P、发展P、神经P、神经学、神经精神病学和数学，并使用了各种神经科学技术，除了行为方法：脑电、功能磁共振、TMS、神经心理评估-从而促进了神经科学和认知视角在“主动知觉”研究中的整合。计划中的研究还包括重点研究正在考虑的功能的发育(正常衰老与病理性衰老)，以及在神经学/精神病学的高级诊断学以及技术应用(例如脑机接口、社交机器人)中的应用领域。

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).
