John Garcia
proved the others wrong
classical conditioning
challenged the idea that all animals could be conditioned equally well
rats were given one taste, sight, sound as a neutral stimulus
later the rats would be exposed to radiation or drugs (the unconditioned stimulus), which would make the rats sick
through these experiments, Garcia discovered that if a rat became nauseated after presented with a new taste, even if the illness occurred several hours later, the rat would avoid that taste
this contradicted the belief that, for conditioning to occur, the unconditioned stimulus (in this case, sickness) must immediately folloe the conditioned stimulus-to-be (the taste)
Garcia also discovered that the rats developed aversions to tastes, but not to sights or sounds
Garcia's discovery, conditioned taste aversion, is considered a survival mechanism because it allows an organism to recognize foods that have previously been determined to be poisonous, hopefully allowing said organisms to avoid sickness
