Classical conditioning :(p. 136)- when an innate reflex is produced by a once neutral stimulus (originally evokes no response: ivan pavlov-russian medical researcher. (dog & bell experiment, conditioned stimulus (cs) unconditioned stimulus, conditioned response, unconditioned response. Extinction-withholding the ucs after the cs leads to elimination of cr: sounding the bell and not giving food leads to elimination of salivation after hearing bell. Spontaneous recovery-cr reappears at quicker rate than when initially learned: case of little albert: Conditioned baby boy to be scared of white lab rat. Generalization-apply the cr to stimuli that are not exact but represent. Discrimination-learning to respond to specific stimuli but not similar. Nauseous feeling (cr) after sight or smell of particular food (cs), if food was once associated with illness: ex. After experience of food poisoning: cancer patients(p. 142)
