House - Tree - Person Projective Drawing Technique

Designed to aid clinician in obtaining information concerning an individual's sensitivity, maturity, flexibility, efficiency, degree of personality integration, and interaction with the environment. Subject is asked to draw pictures of a house, a tree, and a person. Subject is given an opportunity to explain the drawings.

In common with other projective measures of personality (e.g. the Rorschach, or TAT), the H-T-P provides a structured context for the projection of unconscious material. Like a specific ink blot or TAT card, the subject is always presented with blank paper (or a standardized drawing form) and standard instructions as to what is to be drawn (the house, the tree, the person). Combining an ease of administration with a maximum of projective potential, the H-T-P allows the clinician to gather information that might not otherwise be available in a structured, verbal interview.

Unlike the Rorschach or TAT, the H-T-P presents a maximum of ambiguity for the subject. Whereas the Rorschach and TAT present a stimulus card which does not change over time, the H-T-P presents the subject with a completely blank field onto which they are asked to draw and project. Every subject will draw a house, but every house will differ. The result is a collection of projective material organized around standard themes. The H-T-P can claim a great deal of freedom from stimulus bias.

There is a smart computer program (Expert System for Projective Drawings, ESPD) that helps to interpret HTP drawings:

ESPD is an expert system for the psychological interpretation of drawings. The purpose of the software is to help psychologists, psychiatrists, art therapists, teachers, social workers etc. who applies drawing tests for the psychological analysis of the personality. The program is designed for the interpretation of projective drawings, e.g. House-Tree-Person Test, Human Figure Drawings, Tree Drawings, Animal Drawings and Free Drawings. The analysis is performed with sophisticated artificial intelligence techniques. The result is a psychodiagnostic report with diagrams and psychological scales.
