Abstract: The purpose of this experiment is to investigate the ability of generalizationof the golden haired monkey (Rhinopithecus Roxellanae)from three dimensionalobjects to their two dimensional representative photographs and pictures. Wedeveloped a modfied apparatus after WGTA in pushing form, which is suitablefor our own use. The experiment was conducted on 3 golden haired monkeys(2?,1?), aged from 2-3 years. The Ss were birert trained to discriminatebetween two objects:an ink bottle like block and a cabin like gray woodenblock. Then the photos and pictures of the objects were randomly shown tothem to examine if the discrimination could be transfered. All three subjectsshowed no generalization, i. e. they reacted to the photos and pictures rand-omly.
