Effects of Perceived Space on Spatial Attention
Robertson, L.C. & Kim, M. (1999). Psychological Science

ABSTRACT: This study demonstrates that a perceptual illusion that alters the perceived length of two lines also affects spatial attention. We used a cuing method that was introduced to study space- versus object-based attention. Two parallel lines of equal length were placed so that the distance between them was equal to the length of the lines. We then added a scene with depth cues to produce a strong illusion that one line was longer than the other. The results showed that spatial attention is distributed in space as it is perceived and altered by perceptual organization. These data have implications for assumptions concerning the spatial medium that guides attention and the role of depth and distance cues in spatial orienting, as well as for understanding attentional sysmtes related to neuropsychological functions that respond to space and objects.

视觉被补偿?抑或视觉的重新定义?

下面这个实验暂时没找到更详尽的报道。
如果该实验能够确定地排除其他因素而导致现象可靠,那么很多传统的属于练功修习范畴的现象,就不是多么虚诞的传闻。 甚至北大陈守良先生几十年所专致研究的特异功能也因此可以有与之相揭发之处。
大概最有意思的还是研究者怎么去解释或者选择什么样的途径去考虑这个现象:
一个可以明确诊断由于眼睛受损而导致在其视野当中存在盲区的患者,如果他把手放置在该盲区,则其在该盲区的视力有确切地提高。
