This study was aimed at investigating mechanisms of consciousness using bistable perception. In 4 experimental conditions, 1, 2, 4 or 8 Rubin's face-vase ambiguous figures were presented for 3 min.In Experiment 1, 40 subjects looked at the center of the screen and pressed a specific key correspondent to the figure where they perceived a reversal. In Experiment 2, 32 subjects controlled with eye-tracker performed a similar task in which they pressed the spacebar whenever they perceived a reversal in any of the figures.At the end of each condition subjects estimated its duration. Results showed that changing the number of figures does not alter the number of reversals, producing a flat I/O curve between the two parameters. Estimated time lapse showed a negative correlation with the number of reversals. These findings are discussed considering the relationships between bistable perception, attention, and consciousness, as well as the time perception literature.
本研究旨在使用双稳态知觉来探究意识的机制。在 4 种实验条件下，呈现 1、2、4 或 8 个 Rubin 的面孔花瓶歧义图形，持续 3 分钟。在实验 1 中，40 名被试注视屏幕中央，并按下与他们感知到反转的图形相对应的特定键。在实验 2 中，32 名被试用眼动追踪器控制，执行类似的任务，当他们在任何一个图形中感知到反转时，就按下空格键。在每个条件结束时，被试估计其持续时间。结果表明，改变图形的数量不会改变反转的数量，在这两个参数之间产生一个平坦的 I/O 曲线。估计的时间滞后与反转的数量呈负相关。考虑到双稳态知觉、注意力和意识之间的关系，以及时间知觉文献，讨论了这些发现。
