Long-term change refers to a lasting and enduring modification in behavior that persists over time. It involves the establishment of new behavioral patterns that are maintained even after the removal of reinforcement or punishment.
In operant conditioning, extinction occurs when a previously reinforced behavior no longer receives reinforcement, resulting in a decrease or cessation of that behavior.
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.
