Retinal Persistence now and then

Scientists orignally thought retinal persistence was caused by slow movement of the frames in the camera, and the mind saw flashing pictures. But we know thats not true becasue at higher rates of frames per second the retinal persistence is not prevalent as much. The slow frames caused a flicker affect like in a flip book. The sensitivity of a persons peripheral vision will give different degrees of retinal persistence, or the viewing of the picture that you mind still sees even though the frame has passed.
