Erikson and Freud are two of the few theorists who have developed a lifespan approach to development. Freud’s approach to development was psychosexual while Erikson’s was psychosocial. Even though Freud’s theory is better known, Erikson’s theory remains a leading and very much applied model in personality and developmental psychology today. Erik Erikson’s Psychosocial Developmental Stages Erikson believed that each stage of development presents a different crisis that needs to be overcome. If this challenge is resolved, the individual is able to move on to the following stages and lead a healthy, productive life. Industry versus inferiority is the fourth stage of Erik Erikson's theory of psychosocial development, which happens after the third stage of initiative versus guilt.The stage occurs during childhood between the ages of approximately six and eleven. Stage four of Erikson’s theory occurs during the middle school years when children must master skills in math, reading, and writing. At that time the child is faced with the conflict of industry versus inferiority. If the child masters the skills, the child develops a sense of industry and has a positive view of the achievement. Erik Erikson’s Psychosocial Stages (cont.) Age: MIDDLE CHILDHOOD Stage: INDUSTRY VERSUS INFERIORITY Children develop feelings that they can make things, a sense of “I am capable.” FEEDING BEHAVIORS INDUSTRY Child discerns when he or she is hungry or full and acts on these cues.
