- procedures that combine and modeling to eliminate undesirable behaviors and increase desirable responses.
- behaviorism
- An approach that regards directly observable events - stimuli and responses - as the appropriate focus of study and views the development of behavior as taking place through classical and operant conditioning
- child development
- a field of study devoted to the understanding of constancy and change from conception through adolescence and emerging adulthood
- chronosystem
