Poison-induced neophobia in rats: Role of stimulus generalization of conditioned taste aversions

摘要: Rats repeatedly injected with lithium chloride were subsequently tested drinking novel and familiar solutions of both casein hydrolysate vinegar. Injections in the absence edibles result only a small, sometimes not reliable, increased avoidance vinegar solutions. In contrast, if subjects acquired an aversion to saccharin as injections, this learned generalized hydrolysate, generalization greatly enhanced by novelty flavor. However, aversions did generalize solution nearly much These results suggest that previous observations poison-induced neophobia probably part stimulus conditioned taste addition test some other factor, such salience or similarity aversive flavor, is also involved aversions.
