Preferences for wavelength and intensity in rhesus monkeys: fact or artifact?
10 adult male rhesus monkeys were tested to determine whether systematic preferences existed for specific color or brightness of visual stimuli. In contrast with previous reports no significant preferences for either specific hues or brightness levels were found. Perhaps methodological or subject variables may be responsible for preferential responding in other situations and account for the present inability to confirm prior work on preferences for color and brightness.
