实验1证明了颜色对金鱼听觉辨别的混合阻挡-遮蔽效应。在实验2中（线的颜色和角度不同），金鱼被颜色遮挡了角度，颜色被角度遮挡了。在实验3中（同样是线的颜色和角度不同），鲤鱼被颜色遮挡了角度，但同样的动物（如之前的研究中的金鱼）并没有表现出更大的维度内转移而不是维度外转移。这些结果与“阻碍和遮蔽是脊椎动物学习的普遍现象”的假设是一致的。他们还认为，造成遮挡和遮蔽的过程不同于产生空间转移效应的过程。
In Experiment 1, a mixed blocking-overshadowing effect of color on an auditory discrimination was demonstrated in goldfish. In Experiment 2 (with lines differing in color and angle), blocking of angle by color and of color by angle was demonstrated in goldfish, In Experiment 3 (again with lines differing in color and angle), overshadowing of angle by color was demonstrated in carp, but the same animals (like goldfish in a previous study) failed to show greater intradimensional than extradimensional transfer. These results are consistent with the hypothesis that blocking and overshadowing are general phenomena of vertebrate learning. They suggest also that the processes responsible for blocking and overshadowing are different from those which produce the dimensional transfer effect.
