Lift sensations can occur through partial stimulation in the periphery of the temporal field of vision of one eye, by offering vertically moving patterns on a monitor screen. The parameters are: (1) the size of the stimuli offered; (2) the circumference of the area of the field of vision; (3) the degree of periphericity of the area studied, and (4) the angular velocity of the vertically moving patterns. Self-motion sensations can only be aroused if the stimuli offered are observable, i.e. at least compatible in size with the value of the visual acuity in the area of the field of vision that is being examined. By the slow angular velocities of stimuli that are offered at 50 or 60° in the periphery, linear self-motion sensations can arise even when only a small area of the field of vision is stimulated. Enlargement of the area of stimulation and of the objects of stimulation induce increased sensations, at lesser peripherals as well as by higher angular velocities. During this optokinetic stimulation, a vertical line, placed in front of the subject, seems to be slightly tilted.
