Abstract

THIAMINE-SPECIFIC HUNGER CAN BE ADEQUATELY EXPLAINED IN TERMS OF A LEARNED PREFERENCE, FACILITATED BY THE NOVEL-DIET PREFERENCES SHOWN BY THIAMINE-DEFICIENT RATS. A SERIES OF EXPERIMENTS FAILED TO PROVIDE EVIDENCE FOR AN UNLEARNED SPECIFIC PREFERENCE FOR THE TASTE OR SMELL OF THIAMINE IN SUCH SS. LEARNING EXPLANATIONS ALSO APPEAR ADEQUATE TO ACCOUNT FOR CALCIUM HUNGER AND MAGNESIUM AVERSION. IN CONTRAST, SODIUM-DEFICIENT RATS SHOW A SPECIFIC PREFERENCE FOR THE TASTE OF SODIUM SALT WHICH OVERWHELMS THEIR PREFERENCE FOR ARBITRARY NOVEL DIETS. THE IMPROBABILITY OF A LEARNED PREFERENCE FOR SODIUM IS INCREASED BY EVIDENCE THAT IN SOME CASES SODIUM INGESTION MAY HAVE AVERSIVE CONSEQUENCES FOR SODIUM-DEFICIENT RATS. (16 REF.)
