| Popis: | Sutnmary.-This experiment dealt with the role oE strobe frequency on the rod and frame effect in frame-dependent and frame-independent subiects in light of the destabilizing effect of strobe lighting on body posture. Analysis showed that the frgme effect was resistant to strobe illumination and was sigdicantly stronger at 2 Hz than at 9 Hz. Since the srroboscopic ec Witkin & Asch, 1948), some subjects misjudge the visual vertical and tend to err in the direction of the frame's tilt; this hen omen on is known as the frame effect. The most common explanation for the occurrence of the frame effect is the visuovestibular interaction (Ebenholtz, 1985a, 1985b, 1990; Ebenholtz & Callan, 1980). The frame effect may be regarded as the static form of roll vection (Dichgans & Brandt, 1978; Ebenholtz, 1977; Howard & Templeton, 19661, and as such, the frame contributes to the control of body posture and egocentric orientation, both of which are principally dependent on peripheral visual information (Leibowitz & Post, 1982). Indeed, studles have shown that the influence of the frame extends to the control of body sway (Witkin & Wapner, 1950). Thus, an upright observer in front of a tilted surroundmg frame has the sensation of being tilted in the opposite direction (Ebenholtz & Benzschawel, 1977; Sigman, Goodenough, & Flannagan, 1978). This postural effect in turn influences the positioning of the rod. Therefore, individual Merences in the effect of the tilted frame could reflect differences in vection sen'Address correspondence and requests for reprints to C.
