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”。
In view of the issue of “selective attention to space-based or object-based”, from the controversy between Egly et al. And Vecera et al., We investigate whether the dominant effect of “attention transfer in objects” is related to spatial factors. First of all, consistent with the previous research results, it is observed that when the prompt of space is effective, subjects react more quickly to the target than the prompt is invalid, which indicates the existence of space-based attention component. By changing the shape of two background objects and Color and weaken the perceptual organization between the two, we also find that the dominant effect of “attention transfer in the object” has nothing to do with the spatial distance. The latter result provides further evidence for the existence of the selective attention component based on the object and suggests that the selective attention of the “object” of attention is the “perceived object” formed by the prior perceptual organization process.
