The human species has developed exponentially throughout history, in regards to how cognitive processes and developments function. Many have theories about how humans learn, advance, and how they came to be what they are today. Theories such as Operant and Classical Conditioning are some of the most famous methods of behavior correction, and are used today even though they are over one hundred years old. Research on how infants develop their cognitive thinking helps analysts teach youth in the most efficient ways possible, according to the stage of development said child is at.

Actions will be likely to occur again in the future when rewarded properly. This includes positive reinforcement for good behavior, and negative reinforcement for bad behavior. This theory is used in many areas of modern social development, such as schools and correctional therapy to teach positive actions to the learners. For example if somebody is caught shoplifting, they are punished by jail time, community service or other forms of penalty. This teaches the offender that their actions are wrong, and therefore they will be less likely to commit the crime again. Forms of punishment such as this are excellent examples of Operant Conditioning as the action is shoplifting, the punishment is a verdict determined by a figure of authority. Operant Conditioning is used continually in the criminal justice system to prevent crimes from occurring in the future. According to Sigmund Freud, the human personality is made up of three primary components: the Id, the Ego and the Superego. These components work together to create complex human behaviors. The Id is
