| Abstract(in English) | The present study addresses the problem of what statistics in the intensity distribution in environment determines the state of brightness adaptation. We measured the perceived brightness for a flash stimulus under various adaptation conditions by using the psychophysical methods of brightness matching and magnitude estimation. The results show that the brightness response functions change their forms not only with the mean intensity but also with the variance of the intensity distribution of the adapting stimuli. This suggests the existence of the adaptation mechanism with a relatively long time scale, whose gain may be controlled by the variance of the stimulus intensity. |
