Abstract:
We have analysed several recent studies of suprathreshold contrast perception in terms of the normalization of CTFs originally suggested by Georgeson and Sullivan (1975). When suprathreshold responses for different spatial frequencies are compared it is necessary to consider the effects of normalization across CTFs of different spatial mechanisms.
