What is the theory that explains the way the brain groups items according to proximity and similarity, as well as trying to complete an unfinished pattern or non-existent shape

The correct answer is Gestalt

Gestalt is a client-centered psychotherapeutic approach. This approach helps customers focus on the present. They come to understand what is really happening in their lives now.
