When different stimuli are presented dichoptically, perception alternates between the two in a stochastic manner. After a long-lasting and rigorous debate, there is growing consensus that this phenomenon, known as binocular rivalry (BR), is the result of a dynamic competition occurring at multiple levels of the visual hierarchy. The role of low- and high-level adaptation mechanisms in controlling these perceptual alternations has been a key issue in the rivalry literature. Both types of adaptation are dispersed throughout the visual system and have an equally influential, or even causal, role in determining perception. Such an explanation of BR is also in accordance with the relationship between the latter and attention. However, an overall explanation of this intriguing perceptual phenomenon needs to also include noise as an equally fundamental process involved in the stochastic resonance of perceptual bistability.
当以双眼分视的方式呈现不同刺激时，知觉会以随机方式在两者之间交替。经过长期而激烈的争论，越来越多的人达成共识，即这种被称为双眼竞争（BR）的现象是视觉层级多个层面发生动态竞争的结果。低层次和高层次适应机制在控制这些知觉交替中的作用一直是竞争文献中的关键问题。这两种适应类型都分散在整个视觉系统中，并且在决定知觉方面具有同等影响力，甚至具有因果作用。对BR的这种解释也与它和注意力之间的关系相一致。然而，对这种有趣的知觉现象的全面解释还需要将噪声作为涉及知觉双稳态随机共振的同样基本的过程包括在内。
