When you divide out certain thoughts and isolate them from others, it’s called compartmentalization. Like organizing similar items in different compartments of a desk, compartmentalization separates unrelated thoughts from one another.
Sometimes considered a form of dissociation, compartmentalization is frequently viewed as a psychological defense mechanism. Especially among people who have experienced trauma or other emotionally overwhelming circumstances.
Rather than expose you to painful memories or thoughts, the brain separates them away from the rest of the consciousness — compartmentalizing them.
Under current concepts, however, compartmentalization is now seen as both an unconscious defense mechanism and a psychological tool you can deliberately engage in.
“The benefits of compartmentalization are significant, particularly in managing stress and maintaining focus,” explains Joshua Collins, a licensed clinical social worker and clinical coordinator at SOBA, New Brunswick, New Jersey. “By isolating aspects of life that may cause anxiety or emotional distress, individuals can prevent these feelings from taking over their entire psychological landscape, allowing them to remain productive and composed in various areas of life.”
