摘要

感知以闪电般的速度解决计算要求很高的问题。它从退化的输入中恢复复杂的世界表征,通常在几毫秒内。任何知觉理论都必须能够解释这是如何可能的;换句话说,它必须能够解释感知的计算可追溯性。为数不多的尝试之一是信息封装假说,该假说认为,感知之所以能够快速,是因为它通过放弃对存储在认知中的信息的访问,使计算成本保持在较低水平。我认为,我们没有令人信服的理由相信封装解释了(甚至有助于解释)感知可追溯性,而且有很多理由怀疑它。这是因为与信息访问相比,感知存在更深层次的计算挑战,而这些挑战可能会使访问成本变得无关紧要。如果这是正确的,它破坏了封装的核心计算动机,并将我们送回绘图板,以解释感知可追溯性。

How Is Perception Tractable?
Perception solves computationally demanding problems at lightning fast speed. It recovers sophisticated representations of the world from degraded inputs, often in a matter of milliseconds. Any theory of perception must be able to explain how this is possible; in other words, it must be able to explain perception’s computational tractability. One of the few attempts to move toward such an explanation is the information encapsulation hypothesis, which posits that perception can be fast because it keeps computational costs low by forgoing access to information stored in cognition. I argue that we have no compelling reason to believe that encapsulation explains (or even contributes to an explanation of) perceptual tractability, and much reason to doubt it. This is because there exist much deeper computational challenges for perception than information access, and these threaten to make the costs of access irrelevant. If this is right, it undermines a core computational motivation for encapsulation and sends us back to the drawing board for explanations of perceptual tractability.

期刊介绍: In continuous publication since 1892, the Philosophical Review has a long-standing reputation for excellence and has published many papers now considered classics in the field, such as W. V. O. Quine"s “Two Dogmas of Empiricism,” Thomas Nagel"s “What Is It Like to Be a Bat?” and the early work of John Rawls. The journal aims to publish original scholarly work in all areas of analytic philosophy, with an emphasis on material of general interest to academic philosophers, and is one of the few journals in the discipline to publish book reviews.
