Rhythms of Attentional Exploration and Selection

越来越多的证据表明，我们知觉经验的现象学的、连续的流依赖于一系列离散的时刻，类似于视频剪辑的快照。我们的感知和注意力过程的节奏主要通过行为数据来证明。包括我们在内的研究表明，感知信息是在离散样本中处理的，导致性能在有利和不利时刻之间波动。然而，仍然存在三个关键差距。我们对以下方面知之甚少：（1）在两个知觉样本期间和之间的心理物理表现背后的机制;（2）这些有节奏的心理表征如何在神经水平上实现;（3）我们是否可以在神经表征和行为表现之间建立因果关系。在这个项目中，我们建议使用心理物理学，脑电图（EEG）和经颅磁刺激（TMS）来解决这些及时的问题。杜格博士在巴黎的团队和布施博士在明斯特的团队之间的合作，以及我们在跨国水平上的研究协调（具有可比性和互补性的范式和方法），将更快地加深我们对注意力探索和选择节奏的了解。

Accumulating evidence suggests that the phenomenological, continuous stream of our perceptual experience relies on a series of discrete moments, similar to the snapshots of a video clip. The rhythms of our perceptual and attentional processes have been demonstrated mostly with behavioral data. Studies, including ours, showed that perceptual information is processed in discrete samples, leading to performance fluctuating between favorable and less favorable moments. Yet, three critical gaps remain. Very little is known about: (1) the mechanism underlying psychophysical performance during and between two perceptual samples; (2) how these rhythmic mental representations are implemented at the neural level; and (3) whether we can establish a causal relation between neural representations and behavioral performance. In this project, we propose to address these timely questions using psychophysics, electro-encephalography (EEG) and transcranial magnetic stimulation (TMS). The collaboration between Dr. Dugué's team in Paris, and Dr. Busch's team in Muenster, with the coordination of our research at the transnational level (with comparable and complementary paradigms and approaches) will more quickly further our knowledge about the rhythms of attentional exploration and selection.
