Subjects instructed to imagine a beating pendulum develop pursuit eye movements of a frequency comparable to the frequency of a previously visualized real pendulum. The appearance of pursuit rather than saccadic movements supports an "outflow" theory for central control of eye movement and suggests an objective technique for the identification of certain types of visual imagery.
