Document Summary
A form of classical conditioning in which a gastrointestinal illness becomes a conditioned aversive stimulus. Stimulus generalization: aversion generalizes to other foods that are similar. Extinction: aversion can be placed on extinction with repeated presentations and no illness. Overshadowing: more salient foods may become more aversive than other not-as-salient foods. Blocking: conditioned aversive foods presented may block others from becoming aversive. Latent inhibition: unfamiliar foods may more readily condition to a taste aversion than familiar foods due to historical associations. Major differences between taste aversion and classical conditioning. Cs-us relevance: rats have a predisposition to readily associate nausea with taste, also have a predisposition to readily associate painful events with visual/auditory stimuli. Limits to training: stereotyped action sequences/fixed action patterns may become dominant in settings that resemble the natural environment, the conditioned stimulus (cs) becomes strongly associated with food and elicited species-specific behaviour patterns associated with feeding.
