Abstract
We have shown that the thresholds for egocentric perception of object motion are significantly raised during concurrent head oscillations of ± 20° about the vertical Z-axis and fixation of the target (Degner and Brandt 1981; Brandt 1982). Subjects were exposed to the target which randomly moved either to the right or to the left at a constant angular velocity of 24’ arc/s with a stepwise increase in exposure times from 0.25 to 10 s (20 repetitions of each stimulus condition). Conservative determination of threshold was based on 18 out of 20 possible correct perceptions of movement as well as direction. Sinusoidal active head oscillations raised the detection threshold for object motion by a factor of 2.9 at 1 Hz and 6.4 at 2 Hz oscillations (Fig. 2) despite intended stabilization of the target on the retina. This effect increases disproportionately with increasing eccentricity of the image of the moving stimulus on the retina (Fig. 3).
