Data were obtained on the spectral sensitivity of the light-adapted monkey by two operant conditioning techniques adapted to use with brief duration stimuli: cued avoidance conditioning, and a positive reinforcement-reaction time method. The results are compared with human photopic spectral sensitivity, and detailed similarities are found.
