Document Summary
Noted that stimuli associated with food elicited salivation. Extinction (in above context): does the salivating continue to follow the ringing of the bell without the reward of food? https://onedrive. live. com/edit. aspx?resid=740cce59d570b80e!183&cid=740cce59d570b80e&app=onenote. Ex: little albert (small child) was exposed to a rats (cs) Then a loud noise (ucs) was paired with the cs. These together (paired) formed a fear of rats (ucr/cr) Extinction would include exposing little albert to rats without its paired loud noise over and over again. Cs (familiar injection setting) elicits cr (counteraction to drug; ex. Unfamiliar setting (no cs, no cr) - death by respiratory depression. Cr (anticipation of "high") [just like the salivation in anticipation of food in pavlov"s study] Extinction (cues, cs, without reward of drug, ucs) Result = aversion (strong dislike) to the food (cs) and it"s taste and smell. Doesn"t follow normal rules of cs-ucs-ucr timing (this can take a very long time instead of being very swift and quick)
