Final answer:
Emotional Cutoff in Family Systems Theory refers to the reduction or cessation of emotional contact with family members to manage unresolved emotional issues.
Step-by-step explanation:
In Family Systems Theory, the concept of Emotional Cutoff claims that it is a defense mechanism where individuals withdraw or minimize emotional contact with family members as a way to manage unresolved emotional issues. This can manifest as avoidance of personal interactions, restricting conversations to superficial or functional topics, or physically moving away from family. Emotional Cutoff is often a response to the difficulties in balancing individuality with the emotional interconnectedness of the family system.
