A selection of the literature on vision published in the last 2 years from various neuroscience disciplines is reviewed. It is organized around the notion of independent processing mechanisms for sensory cues such as wavelength, intensity and orientation; these are subsequently integrated for the perception of colour, brightness and contours, for example, which then feed into higher order systems for visual recognition (words and objects) and visuospatial cognition. A strict hierarchical system is, however, not plausible. Apart from the physiological evidence against such a concept, the widespread observations of 'knowledge without awareness' suggest direct links between different levels, which by-pass conscious experience.
本文回顾了过去两年间发表的来自不同神经科学学科的关于视觉的文献选集。它围绕着对诸如波长、强度和方向等感觉线索的独立处理机制的概念展开；随后，这些线索被整合起来用于颜色、亮度和轮廓的感知，例如，然后输入到用于视觉识别（单词和物体）和视觉空间认知的高阶系统中。然而，一个严格的层次系统是不合理的。除了有生理学证据反对这一概念外，“无意识的知识”的广泛观察表明不同层次之间存在直接联系，而绕过了有意识的体验。
