Do rod signals add with S cone signals in increment detection

摘要: Test additivity experiments reveal the combination rules for increment detection by rods and an S cone-dominated mechanism isolated means of chromatic adaptation. The measured was corrected (reduced) to compensate partial each both test wavelengths in combined stimuli. small degree found between rod cone signals under these conditions is consistent with either a rod–cone interaction or probability summation independent mechanisms. This contrasts higher previously M L detection.
