描述了关于知觉分组的近期研究，特别强调确定分组因素起作用的层面。与将分组视为一种早期的、二维的、基于图像的过程的经典观点相反，近期的实验结果表明，它受到与知觉恒常性相关的现象的强烈影响，比如双眼深度知觉、明度恒常性、无模态完型和错觉轮廓。这些发现意味着至少某些分组过程是在现象知觉层面而非视网膜图像层面起作用。据报道的初步证据显示，分组会影响知觉恒常性，这表明分组过程也必定在早期的、恒常性之前的层面起作用。如果是这样，分组可能是视觉组织中一个普遍存在的、持续进行的方面，它发生在每个表征层面，而不是一个相对于其他知觉过程能够明确定位的单一阶段。（C）2003爱思唯尔有限公司。保留所有权利。
Recent research on perceptual grouping is described with particular emphasis on identifying the level(s) at which grouping factors operate. Contrary to the classical view of grouping as an early, two-dimensional, image-based process, recent experimental results show that it is strongly influenced by phenomena related to perceptual constancy, such as binocular depth perception, lightness constancy, amodal completion, and illusory contours. These findings imply that at least some grouping processes operate at the level of phenomenal perception rather than at the level of the retinal image. Preliminary evidence is reported showing that grouping can affect perceptual constancy, suggesting that grouping processes must also operate at an early, preconstancy level. If so, grouping may be a ubiquitous, ongoing aspect of visual organization that occurs for each level of representation rather than as a single stage that can be definitively localized relative to other perceptual processes.
