在正常人和患有小脑功能障碍、帕金森病、右或左大脑半球病变、阿尔茨海默病或科尔萨科夫综合征的患者中研究了棱镜眼镜对视觉侧向位移的视觉运动适应。适应分两个阶段进行分析，棱镜眼镜就位后恢复正常指向（误差减少部分）和眼镜移除后相反方向的误指向（负后效部分）。负后效，这似乎是最好的措施，真正的适应，显着减少，只有小脑患者。这种糟糕的表现支持小脑参与运动学习。
The visual-motor adaptation to lateral displacement of vision by prism glasses was studied in normal individuals and patients with cerebellar dysfunction, Parkinson''s disease, right or left cerebral hemisphere lesions, Alzheimer''s disease, or Korsakoff''s syndrome. Adaptation was analyzed in 2 phases, the return to normal pointing with prism glasses in place (the error reduction portion) and the mispointing in the opposite direction after the glasses were removed (the negative aftereffect portion). Negative aftereffect, which seems to be the best measure of true adaptation, was significantly reduced only for the cerebellar patients. This poor performance supports the involvement of the cerebellum in motor learning.
