在双眼竞争，冲突的单眼图像进行交替抑制。本研究探讨了竞争抑制探测视觉敏感性在竞争与各种探针刺激。当两张脸处于竞争状态时，在抑制过程中，对脸探测的敏感性降低了4倍。当用一个全球运动来探测时，竞争性全球运动也非常激烈。然而，在一个令人惊讶的发现，面部探针的敏感性是完全不受损害的全球运动竞争，和运动敏感性是不受损害的面部竞争。这表明竞争抑制局限于代表图像冲突的神经元，这意味着不同类型的探针不会受到抑制。从感觉上讲，这将使不参与竞争的视觉过程自由发挥正常功能。
During binocular rivalry, conflicting monocular images undergo alternating suppression. This study explores rivalry suppression by probing visual sensitivity during rivalry with various probe stimuli. When two faces engage in rivalry, sensitivity to face probes is reduced 4-fold during suppression. Rivaling global motions also rivaled very deeply when probed with a global motion. However, in a surprising finding, sensitivity to face probes is completely unimpaired during global motion rivalry, and motion sensitivity is unimpaired during face rivalry. This suggests that rivalry suppression is localized to the neurons representing the image conflict, which means that probes of a different kind suffer no suppression. Sensibly, this would leave visual processes not involved in rivalry free to function normally.
