摘要： 针对“选择性注意基于空间还是基于物体”的问题，从Egly等与Vecera等的争论出发，考察“物体内注意转移”的优势效应是否与空间因素有关。首先，与以往研究结果一致，观察到：与提示无效时相比，空间提示有效时被试对目标的反应较快，这提示基于空间的注意成分的存在；通过改变两个背景物体的形状和颜色，减弱两者之间的知觉组织之后，还发现“物体内注意转移”的优势效应与空间距离无关。后一结果为基于物体的选择性注意成分的存在提供了进一步的证据，并提示，选择性注意选择的“物体”是注意前的知觉组织过程所形成的“知觉物体”。

Abstract: To investigate the mechanism of visual selective attention, the present study was designed to further examine whether the controversial "within-object effect" was space-based or object-based. First, the present study replicated the previous finding by observing that the subjects responded foster to validly cued relative to invalidly cued targets, which suggested the existence of space-based attentional component. Moreover,it was found that, perceptual organization between two context objects attenuated by changing their shape and color, the "within-object effect" was independent on the distance. The latter result provided further evidence for the existence of the object-based component of visual selective attention , and suggested that, what visual attention selects is the "perceptual object" grouped by pre-attentive perceptual organization.
