Inborn predispositions to learn were demonstrated with respect to: the separation in time between the cs and us is a critical determinant of conditioning. Learning is unlikely to take place at delays of more than few seconds: (cid:3)equipotentiality(cid:4) premise - it dose not matter what stimuli are used in conditioning. Any cs will be equally good in all contexts. Pavlov: (cid:3)any natural phenomenon chosen at will may be converted into a. Csany visual stimulus, any desired sound, any odor, and the stimulation of any part of the skin(cid:4) Taste-aversion learning - john garcia: exposed rats to flavored water and bright-noisy water, exposed rats to x-rays. 2. gastrointestinal disturbance + nausea: tested drinking of the two waters after x-ray exposure, control experiment with foot-shock. - nausea could not be conditioned to light-noise, nor fear could be conditioned to a taste. - taste-aversion conditioning occurs at delays of over 1 hour. Taste reactivity measure of conditioned taste reactions.
