三个实验研究了情绪信息是否会影响双眼竞争中的知觉优势。在实验1中，背景中的竞争的情绪性面孔和中性面孔与前景中的光栅刺激相结合。结果显示，与情绪性面孔配对的光栅比与中性面孔配对的光栅更占优势。在实验2中，情绪性面孔和中性面孔以分视的方式呈现，不与其他刺激配对。观察到情绪性面孔占优势。通过检查作为脸 - 房子对呈现的正立和倒置的情绪性面孔和中性面孔的优势持续时间，排除了融合和低水平图像差异的影响（实验3）。在这里，只有在正立面孔的条件下，面孔刺激比房子刺激更占优势。此外，正立的情绪性面孔被感知的持续时间明显长于正立的中性面孔。这些结果为情绪意义对双眼竞争的影响提供了进一步的支持。
Three experiments investigated whether emotional information influences perceptual dominance during binocular rivalry. In Experiment 1, rival emotional and neutral faces in the background were coupled with grating stimuli in the foreground. Results showed that gratings paired with emotional faces dominated over those paired with neutral faces. In Experiment 2, emotional and neutral faces were presented dichoptically, without being paired with other stimuli. Dominance of emotional faces was observed. Fusion and low-level image differences were ruled out by examining dominance periods of upright and inverted emotional and neutral faces presented as face-house pairs (Experiment 3). Here, face stimuli dominated over house stimuli only for upright face conditions. In addition, upright emotional faces were perceived for significantly longer durations than upright neutral faces. The results provide further support for the influence of emotional meaning on binocular rivalry.
