PSYC 2330 Lecture Notes - Lecture 9: Conditioned Taste Aversion, Gastrointestinal Disease, Radiography
Document Summary
Inborn predispositions to learn were demonstrated with respect to: the separation in time between the cs & us is a critical determinant of conditioning. Learning is unlikely to take place in delays of more than a few seconds: equipotentiality premise it does not matter what stimuli are used in conditioning. Any cs will be equally good in all contexts. Pavlov: any natural phenomenon chosen at will may be converted into a cs any visual stimulus, any desired sound, any odor, & the stimuluation of any part of the skin . * 1 & 2 are not correct every species has predispositions to learn some things better than others. Taste-aversion learning john garcia: exposed rats to flavoured water & bright-noisy water, exposed rats to x-rays gastrointestinal disturbance + nausea, tested drinking of the 2 waters after x-ray exposure, control experiment foot shock. Nausea could not be conditioned to light/noise, nor fear could be conditioned to a taste.
