Document Summary

Types of conditioning patters: delayed response: tone then shock, slight overlap, trace conditioning: tone, then shock much later, simultaneous conditioning procedure, backward conditioning procedure. While eating near a striped panel, rats would be shocked and then a hedgehog would appear. The rats learned to fear the hedgehog even though it appeared after the shock. Perhaps because rats are prepared to fear hedgehogs rather than striped panels. Two control procedures: explicitly unpaired control: the cs and the us never occur close in time and can lead to inhibitory conditioning, random control: cs and us are programmed to occur randomly. Inhibitory conditioning: the cs prevents the occurrence of the us. The (-) does not indicate whether it is a desirable or undesirable stimulus, it indicates if it inhibits or exhibits the unconditioned stimulus. Excitatory: the cs is a predictor that a us will occur. Inhibitory: the cs is not a predictor that a us will occur.
