当参与者适应时间接近的相等和相反的视觉旋转时，第一次的记忆并不巩固。作者调查了这种逆行干扰是否取决于使用相等和相反的旋转。在第1天，不同组的参与者适应了-30度的旋转，5分钟后进行+30度、+60度或-60度的旋转。在第2天，所有组在-30度旋转上重新测试。观察到逆行干扰（在第1天适应相反符号旋转的组中）或逆行易化（在剩余组中）。在所有组中，学习第二个旋转导致第一个旋转的遗忘，这表明所有的视觉旋转都在争夺共同的工作记忆资源，
When participants adapt to equal and opposite visuomotor rotations in close temporal proximity, memory of the 1st is not consolidated. The authors investigated whether this retrograde interference depends on the use of equal and opposite rotations. On Day 1, different groups of participants adapted to a -30degrees rotation followed 5 min later by rotations of +30degrees, +60degrees, or -60degrees. On Day 2, all groups were retested on the -30degrees rotation. Either retrograde interference (in groups who adapted to rotations of opposite sign on Day 1) or retrograde facilitation (in the remaining group) was observed. In all groups, learning of the 2nd rotation resulted in unlearning of the first, indicating that all visuomotor rotations compete for common working memory resources,
