Studies in cognitive psychology have shown that the deployment of visual attention operates under spatial limitations, rendering its assignment to multiple locations difficult or costly. This study explored whether this conventional understanding applies to human metaattention as well. I measured the spatial distribution of metaattention during viewing of natural scenes and found that participants believed they could attend to multiple locations simultaneously. Study 2 tested whether this tendency could be modified by information about the tendency to overestimation. After participants were informed of this tendency toward overestimation with both verbal instruction and demonstrations of attentional blindness and blindness to these phenomena, the selectivity of metaattention increased. Study 3 demonstrated that participants overestimated their attentional abilities by comparing the metaattentional drawings and the actual behavioral performances of the same participants. These results were consistent with recent findings of metaattentional overestimation in change detection and suggested human insensitivity in monitoring attentional limitations.
认知心理学研究表明，视觉注意力的分配受到空间限制，使得同时分配到多个位置变得困难或代价高昂。本研究探讨了这种传统的理解是否也适用于人类的元注意。我在观看自然场景时测量了元注意的空间分布，发现参与者认为他们可以同时关注多个位置。研究 2 测试了通过关于高估倾向的信息是否可以改变这种趋势。在参与者通过口头指导和对注意盲视和对这些现象的盲目性的演示了解到这种高估倾向之后，元注意的选择性增加了。研究 3 通过比较元注意的绘图和同一参与者的实际行为表现，证明了参与者高估了他们的注意力能力。这些结果与最近在变化检测中元注意高估的发现一致，并表明人类在监测注意力限制方面的不敏感性。
