Several studies have shown that short-term monocular patching can induce ocular dominance plasticity in normal adults, in which the patched eye becomes stronger in binocular viewing. There is a recent study showing that exercise enhances this plasticity effect when assessed with binocular rivalry. We address one question, is this enhancement from exercise a general effect such that it is seen for measures of binocular processing other than that revealed using binocular rivalry? Using a binocular phase combination task in which we directly measure each eye's contribution to the binocularly fused percept, we show no additional effect of exercise after short-term monocular occlusion and argue that the enhancement of ocular dominance plasticity from exercise could not be demonstrated with our approach.
多项研究表明，短期单眼遮盖可在正常成年人中诱导眼优势可塑性，其中被遮盖的眼睛在双眼视觉中会变得更强。最近有一项研究表明，在通过双眼竞争进行评估时，锻炼可增强这种可塑性效应。我们提出一个问题，锻炼带来的这种增强效应是否具有普遍性，即在使用双眼竞争所揭示的指标之外，对于其他双眼处理指标也能观察到这种效应？通过一项双眼相位组合任务，我们直接测量每只眼睛对双眼融合感知的贡献，结果显示短期单眼遮盖后锻炼并无额外效应，并认为我们的方法无法证明锻炼能增强眼优势可塑性。
