Step-by-step explanation:
In family systems theory, "Differentiation of self" refers specifically to B) The process of maintaining one's individuality within the family. Differentiation of self involves an individual's ability to separate their own intellectual and emotional functioning from that of their family. It's a concept introduced by psychiatrist Murray Bowen, and it's central to his family systems theory. Differentiation means being able to have different beliefs and values than your family members have and to establish a sense of self that is independent of the family's influence while still maintaining emotional connection to them. This concept is important for understanding how individuals develop a healthy sense of self and navigate their relationships both within the family unit and in the broader society.
As a person progresses through the family life cycle, they may experience increased feelings of independence and individuality, and no longer feel like just "one of the family". This is part of the complex process of socialization and self-development, which occurs throughout a person's life as they prepare for new social environments and expectations.
