Problem: The theory rests on several vital concepts: The self-system: This protective mechanism helps you avoid anxiety. It works by organizing experiences that threaten your security. Your self-system grows from interpersonal interactions and acts as both shield and filter. Dynamisms: These patterns of transformation link energy with situations. They become your usual ways of connecting with others. Personifications: These mental images build from emotional experiences with others. Sullivan saw three main personifications: the "good me" (tied to reward), the "bad me" (tied to punishment), and the "not me" (tied to overwhelming anxiety). Why are these all important when applying to the real world. Need Assignment Help?
