Course Introduction
Behavior Modification Exam Questions
Behavior Modification explores the principles and techniques used to understand, predict, and change human behavior through the application of learning theories. Students study the foundations of classical and operant conditioning, reinforcement, punishment, shaping, and modeling. The course emphasizes practical strategies for assessing and modifying behavior in various settings, such as schools, workplaces, and clinical environments. Through case studies and applied activities, students learn to design, implement, and evaluate behavior change programs, considering both ethical implications and cultural factors in behavior modification.
