Grating detection and identification: comparison of postadaptation reaction times.
The effect of pattern adaptation on grating detection and grating identification was investigated by the method of reaction time. The test and adapting stimuli were sinusoidal vertical gratings. Adaptation caused a spatial frequency-selective increase of the mean detection reaction times. However, the mean identification reaction times were delayed regardless of the adapting spatial frequency. The similarity of the present results with some data about visually evoked potentials is discussed.
