熟悉和可识别的刺激在双眼竞争中具有优势，这种优势通常归因于它们在优势阶段的加工增强。然而，熟悉和可识别的刺激在打破抑制方面是否有优势？测试图像逐渐被引入一只眼睛，以与呈现给另一只眼睛的标准高对比度动态噪声模式竞争。结果表明，面对相同的抑制噪声，直立脸比倒立脸获得优势所需的时间更短。结果还表明，中文读者比希伯来语读者更快地获得优势，而希伯来语读者则相反。这些结果表明，熟悉和可识别的信息，即使是被压抑和不可见的信息，处理方式也与不熟悉的信息不同。显然，关于视觉形式的高级信息确实有助于刺激在抑制阶段的强度。
Familiar and recognizable stimuli enjoy an advantage of predominance during binocular rivalry, and this advantage is usually attributed to their enhanced processing during the dominant phase. However, do familiar and recognizable stimuli have an advantage in breaking suppression? Test images were gradually introduced to one eye to compete against a standard high-contrast dynamic noise pattern presented to the other eye. Results showed that an upright face took less time than an upside-down face to gain dominance against the identical suppression noise. Results also showed that for Chinese readers, Chinese characters were faster to gain dominance than Hebrew words, whereas for Hebrew readers, the reverse was true. These results suggest that familiar and recognizable information, even when suppressed and invisible, is processed differently from unfamiliar information. Apparently, high-level information about visual form does contribute to the strength of a stimulus during its suppressed phase.
