Although several studies have examined infants' sensitivity to perceptual organizational cues, few have examined the functional relations among these cues. We examined how uniform connectedness (UC) functions in relation to shape and luminance similarity. UC has been characterized as the entry-level mechanism of perceptual organization and would therefore be predicted to be more salient than the other two cues. We found that UC was more salient than shape similarity organization was, to the point that 6- to 7-month-old infants failed to even organize on the basis of shape in the presence of UC. Luminance similarity, however, was more salient than UC, even though UC was detected by infants in the presence of luminance cues. We conclude that UC is not necessarily the most salient mechanism of perceptual organization in infancy. Moreover, the luminance-UC-shape salience hierarchy exhibited by 6- to 7-month-olds in the present study is consistent with the order of development of sensitivity to these organizational cues.

婴儿期感知性组织提示中的均匀连接性，亮度和形状相似性之间的关系。

尽管有几项研究检查了婴儿对感知性组织暗示的敏感性，但很少有研究检查这些暗示之间的功能关系。我们研究了形状和亮度相似性如何统一连接（UC）。UC被认为是感知组织的入门级机制，因此可以预测它比其他两个线索更为突出。我们发现，UC比形状相似性组织更为突出，以至于在存在UC的情况下，6至7个月大的婴儿甚至无法根据形状进行组织。但是，即使婴儿在有亮度提示的情况下检测到UC，亮度相似度也比UC更为突出。我们得出的结论是，UC不一定是婴儿期感知组织的最重要机制。此外，
