What is the difference between Erikson and Skinner theory?

Erikson's theory is centered on the social development of humans. Each stage of development, for a total of 8 stages, is centered on a crisis including two poles. It is a turning point at which the ego can be strengthened, or made more vulnerable. For example: * Young Adulthood (19-40 years) * Psychosocial Crisis: Intimacy vs. Isolation * Virtue developped : love Skinner's theory is centered on learning, or more precisely, on operant conditioning, in which a person's or an animal's behaviour is reinforced through the use of consequences. Ex: A rat that learns to press a lever to receive sweetened water drops.
