What is the primary focus of behavior analysis?

The primary focus of behavior analysis is the modification of observable behaviors. This discipline centers on understanding and changing behaviors through various interventions based on the principles of learning, especially as they relate to reinforcement and punishment. Behavior analysts assess how behaviors are learned and maintained, applying this knowledge to encourage positive behavior change in individuals.

Behavior analysis does not primarily focus on internal states such as thoughts and emotions, which is why options related to cognitive processes and the assessment of emotional responses are not considered the core of this field. While developmental psychology may provide context for understanding behaviors in different life stages, it is not the fundamental focus of behavior analysis itself. Instead, behavior analysis emphasizes directly observable behaviors, making option C the most appropriate answer.
