It was previously observed (I) that the vater and food consumption of rats was depressed during exposure to a relatively low dose of low-intensity gamma radiation. 'The severity of this depressian increased with successive ex- posures to radiation, although consump- tion between exposures was similar to or exceeded that of nonirradiated controls. It was suggested that the progressive change in consurnrnatory behavior during repetitive exposure may be, in part, a conditioned response in whch the avoidance of water and food is strength- ened by learning through repeated coupling with the radiation situation. 心理学空间P%s9Ggil%QC

A clearer demonstration of the learn- ing phenomenon would be provided if the conditioned avoidance of water or food could be elicited in the absence of radia- tion exposure. This report (2) describes the results of an experiment designed to prolide such a tcst. The water available during irradiation was made discrimina- ti~e to the animal by the addition of saccharin. Subsequently, the saccharin flavor was employed as a taste stimulus in a postirradiation test for a conditioned avcrsion to the discriminative fluid. The animals were Sprague-Dawley stock bred at this laboratory. Eaeh ani- mal was maintained, in an individual cage. Two plastic 100-ml drinking Bottle? with glass nipples wcre attached ro each cage except during specified periods. The difference imweight of each drinking bottle and of its contents before and after a given test period was used( as the estimatc of fluid consumption. 心理学空间NK5W~4i-pKa
