According to the psychosocial theory of development proposed by Erik Erikson, adolescents go through the stage of "Identity vs. Role Confusion." This stage typically occurs during adolescence, which is when individuals are trying to figure out their own identity, roles, and contributions to society. If the conflicts and challenges at this stage are unresolved, it can lead to feelings of confusion about oneself and one’s place in the world.
In Laurie's case, her stress and recurring physical symptoms seem to be related to pressures she faces in her academic life, particularly around identity and achievement. The difficulty she has in choosing topics for her assignments and the resulting stress might reflect her struggle with identity formation and her desire to live up to certain academic expectations. Therefore, her unresolved conflict at this stage can lead to role confusion, which is related to both identity formation and the general challenges of adolescence.
Given this understanding, the correct answer is:
d. A, B and C
This captures the idea that Laurie's unresolved conflicts can lead to issues related to adolescence, role confusion, and identity formation.
