Document Summary
Problems with classical conditioning explanations of taste aversion: One-trial acquisition of taste aversion (cc usually requires multiple trials) Delayed conditioning of taste aversion (cc usually requires a cue - ns being presented before cs) Selectivity in taste aversion learning (animal skills matter in how they attribute the cause of their sickness) Taste aversions often occur a long time after exposure to an illness- inducing food. Taste aversions will only be associated with the new taste. Latent inhibition: pre-exposure to a stimulus, or a complex of stimuli, lessens the likelihood that associations will later form between that stimulus and subsequent negative outcomes. If you ate oysters a couple of times and didn"t get sick, when you do get sick, you don"t blame the oysters. For a-group rats, exposed to both noise and light followed by a shock, exposure to the light alone leads to a suppression of ongoing bar-pressing behavior.
