Document Summary
Extinction: a cr is weakened or eliminated when the cs is repeatedly presented without the us. Tone:shock fear (ns: us ur) Tone no fear (tone is a ns ) The person avoids their fear, they don"t get the exposure they need to get over their fear. The cs does not actually go back to be a ns. Spontaneous recovery is the reappearance of a cr to the cs following a delay after an extinction. Rest, in situation without tone for awhile. Each time the behaviour recovers, it is usually weaker than before and extinguishes more quickly. Learning to inhibit the response to the stimulus. When doing an extinction process, must be persistent. Disinhibition is the sudden recovery of an extinguished cr when a novel stimulus is introduced. The assumption that the light has interfered with the inhibition. Dishabituation is the recovery of habituated response. Disinhibition is the recovery of an extinguished response.
