当一个人被要求注视时，他会旋转眼睛，使注视目标的图像落在他的中央凹花束内，这是他视网膜上最能看到细节的部分。如果他被要求保持注视目标，他的眼睛会做出一致但独特的缓慢和快速的微型眼球运动模式。这种保持的注视模式传统上被认为是“非自愿的”、“自发的”或“反射性的”，主要是因为这些眼球运动非常小（比普通的自愿运动行为小得多），而且还因为个人通常不知道打算或实际上进行任何这些小的眼球运动（1）。我们认为，传统观点并不完全正确。
When a human being is asked to fixate, he rotates his eye causing the image of the fixation targetto fall within his foveal bouquet-the part of his retina where he sees details best. If he is then asked to maintain fixation on the target, his eye makes a consistent but idiosyncratic pattern of slow and fast miniature eyemovements. This maintained fixation pattern has traditionally been considered to be" involuntary,"" spontaneous," or" reflexive," largely because these eyemovements are extremely small (much smaller than ordinarv voluntary motor acts), and also because the individual is not ordinarily aware of intending to make or of actually making any of these small eye movements (1). We believe that the traditional view is not entirely correct.
