The approach to psychology that focuses on the organization of perception and thinking in a "whole" sense:

Gestalt perspective

Explanation:

Gestalt psychology was proposed by Kohl-er Koffa and Wertheimer. The meaning of this German word gestalt means the whole picture at once. It is the school of psychology that perceives the whole world at once. Sometimes it is also called the simplest form of psychology. Gestalt psychology explained that the whole object is more important than the sub-part of an object. It describes the unique perception of an object. Proximity, similarity, closure, figure and ground some are the form of Gestalt psychology.  

Thus here Gestalt psychology is the psychology that focuses on the organization of perception and the thinking as a whole.
