STROBE FREQUENCY IN THE ROD AND FRAME EFFECT

This experiment dealt with the role of strobe frequency on the rod and frame effect in frame-dependent and frame-independent subjects in lig ht of the destabilizing effect of strobe lighting on body posture. Ana lysis showed that the frame effect was resistant to strobe illuminatio n and was significantly stronger at 2 Hz than at 9 Hz. Since the strob oscopic effect was not related to the extent of the frame effect obser ved in normal light, there was no over-all dependence on the different components of the visual field (static and kinetic). Moreover, analys is of eye movements during stroboscopic exposure confirmed previous ob servation of a visual scanning style related to orienting activity.
