Abstract
Three groups of rats were given 4 days of exposure to saccharin solution: for the recovery group, exposure to saccharin was paired with recovery from thiamine deficiency; the familiarity group was given sacccharin without experiencing either illness or recovery from illness; the recovery-familiarity group was given saccharin after recovering from thiamine deficiency. When these groups were later given saccharin solution followed by an injection of lithium chloride, only the familiarity and recovery-familiarity groups showed a strong long-lasting aversion to saccharin solution. The results are discussed in relation to the previously observed effects of novelty on food preferences and taste aversions in the rat.
