The author believes that the perception of moving objects is distinct from other visual perceptions. The object of the experiments was to discover whether, when a moving object is observed peripherally, a perception of change of position is ever observed without perception of movement. Reports were obtained from six persons. The observer sat, fixating a point on a wall facing him. At his left was a screen with a circular opening of 12 cm., behind which a strip of paper was made to pass by means of electrically driven drums, and on it, at 12 cm. intervals, were disks of black paper 1 cm. in diameter.
The motor started, the observer was asked to fixate on the wall an excentric angle of 100 degrees, to decrease the latter in steps of 5 degrees and to report observations.
Three observers reported changes of position of the spots at excentric
