本研究利用双眼竞争来检验情感相关图片在视觉系统中是否被优先处理。当两幅不相容的图片分别呈现给双眼时就会发生双眼竞争。如果图片无法合并为一个单一明确的知觉，双眼竞争就会导致两种知觉交替出现。然而，情感图片内容是否会影响图片的相对优势一直存在争议。向45名健康参与者呈现了20对来自国际情感图片系统（IAPS）的情感图片和中性图片。正如所假设的那样，无论是在首次知觉方面，还是在每次试验的总观看时间方面，情感图片都明显比中性图片更具优势。我们得出结论，双眼竞争中情感图片的相对优势为视觉系统中情感刺激的优先处理提供了进一步的支持。
This study used binocular rivalry to examine whether emotionally relevant pictures are processed preferentially in the visual system. Binocular rivalry occurs when two incompatible pictures are presented to both eyes. If the pictures cannot be merged to a single unambiguous percept, binocular rivalry results in an alternation of the two percepts. However, it has been controversial whether emotional picture content can influence a picture's relative predominance. Twenty pairs of emotional and neutral pictures from the International Affective Picture System (IAPS) were presented to 45 healthy participants. As hypothesised, emotional pictures significantly predominated over neutral pictures, both with respect to the first percept and the total viewing time across each trial. We conclude that the relative predominance of emotional pictures in binocular rivalry provides further support for the preferential processing of emotional stimuli in the visual system.
