Answer:
Adolescent
Step-by-step explanation:
According to Erikson's theory, there are eight different stages of psychosocial development in which individuals pass through from infancy to late adulthood. Individuals that are of age 13 to 19 tend to have an "Identity crisis." Whereby they are having identity versus role confusion which are often influenced by role models and or peer group. In this stage, they constantly ask the question of "Who am I? And Who can I be?"
Hence, in this case, given that Justin appears to have an identity crisis, Erikson would say that Justine appears to be an ADOLESCENT.
