EFFECTS OF REPEATED FOOD DEPRIVATIONS AND REPEATED FEEDING TESTS ON FEEDING BEHAVIOR

DETERMINED SERIES EFFECTS OF REPEATED FOOD DEPRIVATIONS AND MILK INGESTIONS UPON TEST MEASURES. WHEN MALE ALBINO CHARLES RIVER CD STRAIN RATS WERE PLACED IN THE TEST CAGE, THEY DRANK LITTLE MILK. MILK INTAKE GRADUALLY INCREASED AS A FUNCTION OF DAYS OF TESTING. IT IS CONCLUDED THAT A LARGE PORTION OF THE TREND IN MILK INTAKE ACROSS DAYS WAS DUE TO THE REPEATED TEST EXPERIENCES. UNDER THE PRESENT CIRCUMSTANCES, WHERE CUMULATIVE WEIGHT LOSS WITH REPEATED DEPRIVATIONS WAS AVOIDED, LITTLE OR NONE OF THE TREND COULD BE ATTRIBUTED TO REPEATED DEPRIVATIONS. STUDIES EMPLOYING REPEATED MEASURES ON THE SAME SS SHOULD INCORPORATE ADEQUATE CONTROLS FOR SERIES EFFECTS.
