Extinction: In operant conditioning, extinction occurs when a previously reinforced behavior no longer receives reinforcement, resulting in a decrease or cessation of that behavior.
Spontaneous Recovery: Spontaneous recovery refers to the reappearance of an extinguished response following a rest period after extinction.
Generalization: Generalization is the tendency for similar stimuli to elicit similar responses. In terms of behavior change, it means applying learned behaviors in various situations or contexts beyond where they were initially learned.
