    Generalization, Discrimination, and Extinction

    1.3K
    Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
    Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...
