House-Tree-Person test (HTP), also known as "House-Tree-Person test", abbreviated as "HTP".
In this test, the consultant gives the visitor a pen, eraser, and paper, asking them to draw a picture on white paper with the themes of "house," "tree," and "person." Then, based on certain standards, the drawings are analyzed, evaluated, and interpreted to understand the visitor's inner world.
Similar to the sand box therapy method that Nan Zhubin commonly uses, House-Tree-Person is also a type of projective test belonging to the psychoanalytic school, aimed at exploring the visitor's subconscious.
Utilizing House-Tree-Person, visitors can present their thoughts, which they cannot describe in words, or even those they have not yet realized, in the form of drawings, offering the consultant a more direct perception and judgment.
