【摘要】：选择性注意是指在注意的同时有意识地对非注意对象进行抑制，使之不致进入意识的心理功能。目前，选择性注意的大部分理论都是基于二维条件下的研究得到的。但在现实生活中，我们是处在一个三维的世界中，，因此二维条件下注意的分配理论是否可以拓展到三维领域一直存在争议。本研究主要使用额外单例范式，讨论三维条件下不同干扰属性产生的注意捕获是否有别于二维条件。实验一探讨在实验场景下不同干扰属性产生的注意捕获情况。结果显示注意的捕获不显著，而且三维条件设置没有起到作用。可能是由于呈现了注视点的缘故，导致被试无法在短时间内呈现完整的三维感知效果以及影响了注意窗口的大小。实验二采用整体背景加深的方式来提醒被试注意，并且将注视点删去。结果显示，当出现了作为奇异颜色刺激的绿色圆形时，被试搜索靶子的反应时明显减慢，表明被试在第一时间出现了注意捕获。实验二出现三维效果而不显著，表明深度空间的作用虽然产生，但可能并没有以前研究者预期的那么大，即由于深度条件的设置所带来的注意分配的损耗并不足以影响由新异刺激带来的强烈的注意捕获所增加的那部分反应时。因此，可以推断，注意在深度上的分配并不是“深度盲”的，但可能没有前人所预期的那样强烈。
[Abstract]:Selective attention refers to the psychological function of consciously suppressing unnoticed objects while paying attention to them so that they do not enter into consciousness. At present, most of the theories of selective attention are based on two-dimensional conditions. However, in real life, we are in a three-dimensional world, so whether the distribution theory can be extended to the three-dimensional field has always been controversial. In this study, an extra singleton normal form is used to discuss whether the attention capture generated by different interference attributes under three dimensional conditions is different from that of two dimensional conditions. Experiment 1 discusses the attention capture of different interference attributes in the experimental scene. The results show that the capture of attention is not significant, and the three-dimensional condition setting does not play a role. It may be due to the presence of fixation points that the participants are unable to present a complete 3D perception effect and affect the size of the attention window in a short period of time. In experiment 2, the whole background was used to remind the participants, and the fixed point was deleted. The results showed that the response time of the target was obviously slowed down when the green circle appeared as the stimulus of strange color, which indicated that the attentional capture appeared in the first time. Experiment two has a three-dimensional effect that is not significant, suggesting that the effect of depth space, although produced, may not be as large as previously anticipated by researchers. That is, the loss of attention distribution caused by the setting of depth conditions is not enough to affect the increased response of the intense attention capture caused by the new and different stimuli. Therefore, it can be inferred that the distribution of attention in depth is not "depth blind", but may not be as strong as previous expectations.
