Acceptance of novel flavours is increased after early experience of diverse tastes

It is found that the more an animal experiences diversity of flavours at one time the more it will accept novel flavours later, and this effect is found with rats using flavoured solutions rather than solid foods.

Abstract

WE believe that the more an animal experiences diversity of flavours at one time the more it will accept novel flavours later. Thus, rats given several distinctive flavours early in life would be more likely to accept an unfamiliar flavour later than would rats whose early gustatory experiences have been less varied. This hypothesis has had some empirical support in the literature. Kuo1, for example, mentions pilot research suggesting that cats, dogs and mynah birds raised on restricted diets for extended periods avoided new food, while others of their kind reared on varied diets ate novel foods readily. We have now found a similar effect with rats using flavoured solutions rather than solid foods.
