当从中央凹处观察一些孤立的特征时,一个人的双眼视差的变化会引起其他人的明显深度变化。对于相隔几分钟弧度的特征,其效果相当于其视差信号的汇集,即使这些特征被明显地视为分离的。当它们之间的距离为 4-6 弧分或更长时,效果是相反的:这些特征的表现就好像它们在深度上相互排斥。使用空方法,可以用数字来表征这种相互作用效应。观察者之间存在一些定量的差异,但没有定性的差异,并且在任何一位观察者中,垂直分离的目标之间的视差相互作用不一定与水平分离的目标之间的视差相互作用相同。在 50 毫秒和 1 秒持续时间的演示中都可以看到视差交互效应。当诱导侧翼的消失与测试目标开始同步时,会出现非常小的时间后效应。
When a few isolated features are viewed foveally, changes in the binocular disparity of one introduces apparent depth changes in others. For features a very few minutes of arc apart, the effect is equivalent to a pooling of their disparity signals, even though the features are seen distinctly as separate. When the distance between them is 4‐6 minutes of arc or more, the effect is in the opposite direction: the features act as if they repelled each other in depth. Using a null method, it was possible to characterize this interaction effect numerically. There are some quantitative, but no qualitative, differences between observers, and in any one observer the disparity interaction between vertically separated targets is not necessarily the same as between horizontally separated ones. The disparity interaction effect is seen with presentations both of 50 ms and of 1 s duration. There is a very small temporal after‐effect, seen when the extinction of inducing flanks is synchronous with test target onset.
