Since the seminal debates between Helmholtz and Hering, scientists have debated how to best conceptualise how to understand perceptual organisation. One view treats perception as a form of unconscious probabilistic inference; the other treats perception as a consequence of underlying neural dynamics that is responsible for generating our experience. The project will explore a particularly vivid class of illusory contour stimuli that appear to defy probabilistic accounts of perceptual organisation. The results of these studies promise to shed light on both specific models of contour synthesis, and the broader theoretical issues involved in understanding the active role of visual processes in structuring our experience.

自从亥姆霍兹和赫林之间的开创性辩论以来，科学家们一直在争论如何最好地概念化如何理解感知组织。一种观点认为知觉是一种无意识的概率推理;另一种观点认为知觉是负责产生我们经验的潜在神经动力学的结果。该项目将探索一个特别生动的类的虚幻轮廓刺激，似乎无视知觉组织的概率帐户。这些研究的结果有望阐明轮廓合成的具体模型，以及理解视觉过程在构建我们的经验中的积极作用所涉及的更广泛的理论问题。
