Document Summary
Frequencies further away from 500hz produce a weaker conditioned response: when charting the level of response (y-axis) vs. Conditioned response o for example, we may restrict the conditioned response towards a certain breed of dog by continuously showing a picture of it: unlike extinction, the rest of the generalization gradient remains intact. Discrimination just narrows down the conditional stimuli that invoke the conditional response: cs+ and the cs- o through discrimination training, we can shape the level of conditioned response generated in a generalized conditioned stimuli. This is typically the portion which produces zero conditioned response after discrimination training. For example the 500hz (cs+) sound is followed by the unconditional stimulus of shock while the. After discrimination testing, the subject will not react to the 600hz stimuli while they will react to all the other generalizations of the conditioned stimuli (ranging from 0hz- 580hz) cs 600hz us none . Cs 500hz us shock us/cr fear of.
