Middle Childhood (ages 6-12)
Erickson described the psychological crisis of middle childhood as "Industry versus Inferiority". Industry refers to a child's internal sense of competence. Do they believe they are capable to accomplish age-appropriate tasks, such as making friends, playing team games, succeeding in school?
Early Adolescence (ages 12 to 18)
Erikson's stages (as adapted in Newman & Newman, 2006) describes the crisis of Early Adolescence as "Group Identity versus Alienation". During the middle school and high school years adolescents are attempting to find their place in the social stratus of their peers. This means becoming part of a group, identifying with that group as whole, forming intimate friendships within the group, and participating in mutual activities.
