The school of thought that defines psychology as a study of observable behavior is behaviorism.
According to the behaviorism school of thought on learning, all behaviors are taught through conditioning, and conditioning is the outcome of environmental interaction. According to behaviorists, environmental cues have an impact on how people behave. The tenet of this school of thought, frequently referred to as behavioral psychology, is that conduct can be empirically and scientifically studied regardless of one's own internal mental processes.
Because cognition, emotions, and mood are just too subjective to be studied, the behavioral psychology theory proposes that only observable behavior should be investigated. According to strict behaviorists, everyone can be trained to complete any task, regardless of one's physical limitations, personality traits, or inner thoughts. The only thing needed is good conditioning.
