Positive after-images (PAIs) evoked by low intensity stroboscopic flash are erased by voluntary large amplitude saccadic eye movements. The duration of the PAI is shortened by a Jendrassik manoeuvre. The results suggest that muscle spindle afferent impulses conducted centrally are involved in the erasure phenomenon. The duration of the PAI is modifiable by drugs. The social implications of PAI are considered briefly.
低强度频闪闪光诱发的正后像（PAIs）可通过随意的大幅度眼球快速运动消除。正后像的持续时间可通过詹德雷西克动作缩短。结果表明，向中枢传导的肌梭传入冲动参与了消除现象。正后像的持续时间可被药物改变。简要讨论了正后像的社会影响。
