没有经验的观察者在经历随机点立体对的立体感知之前表现出延迟。这种感知时间随着立体图的重复曝光而逐渐减少。我们研究了这种感知学习效应的特异性，使用由短斜线元素组成的立体图。由45°线元素组成的立体图学习完全转移到具有相同元素方向的不相关模式，但转移到具有相反倾斜方向的元素的模式有明显的失败。因此，所获得的立体技能可能是在训练期间受到刺激的定向分析者所特有的。
Inexperienced observers show a delay before experiencing the stereoscopic percept from a random-dot stereo pair. This perception time is progressively reduced with repeated exposures of the stereogram. We have investigated the specificity of this perceptual learning effect, using stereograms made up of short oblique line elements. Learning with a stereogram consisting of 45° line elements transferred completely to an uncorrelated pattern with the same element orientation, but there was a marked failure of transfer to a pattern whose elements had the opposed oblique orientation. Thus the stereoscopic skill that has been acquired may be specific to those orientation analysers that were stimulated during the training period.
