Spatial Frequency Adaptation under a Slit-Vision Condition
Summary :
This paper describes a series of experiments on spatial frequency adaptation. The adapting stimulus was a vertical square-wave grating which was moved right and left with constant velocity at the back of a stationary vertical slit. By setting the slit width narrower than a half cycle of the grating, adapting stimuli can be confined to only single edges and bars which repeatedly appear in the slit. Even under this slit vision condition, when adapting frequency was low (0.3, 0.5 and 0.75 c/deg), threshold elevations occurred in the same way as without the slit, where several cycles of the adapting grating could be seen. The position of the largest peak in the elevation profile corresponded to the fundamental frequency of the adapting grating, and the second peak always appeared at a frequency higher than 2 c/deg. The second peak corresponds to a higher harmonic frequency in the adapting stimulus and 2 c/deg corresponds to the lowest adaptable frequency of a sustained system.
