Drawing therapy is a diagnostic and therapeutic process that uses drawing and its creative freedom of expression to bring out the subconscious repressed feelings and conflicts, and to express and satisfy them in the process of drawing. Both adults and children can present a complete expression in the space of a few inches, and can satisfy their psychological needs in the process of “appreciating themselves”. As a “subtle” language, the counselor can decipher the code of the mind through the painting, and analyze the “symptoms” that are deeply troubling people. As an effective tool for psychological diagnosis and treatment, it can be said that “silence is better than sound, and indistinct descriptions can be seen” – the effectiveness of diagnosis and treatment by means of painting is huge and unique. Painting is the expression of the subconscious mind, painting applies the projection technique, and painting has a rich language and clear connotation. As a tool for emotional expression, painting can reflect people’s inner, subconscious level information, and is the process of visualizing the subconscious content. People are less defensive about drawing and unconsciously project their deep inner motivations, emotions, anxieties, conflicts, values and desires in their drawings, sometimes releasing more quickly what was hidden or repressed in their early memories and beginning to reconstruct the past. Thus, drawings convey a far richer and more expressive message than words. Moreover, in the process of drawing, individuals can further clarify their thoughts, make the intangible tangible, and concretize the abstract into mental imagery. Human beings have pictures first and then words, and children also learn to draw before they learn words. A picture is worth a thousand words – because pictures convey more information than words, and reading pictures is the easiest and most direct way to understand people’s inner world. Any scribble, the size of the drawing, the weight of the brush, the spatial configuration, the colors, the composition, etc., have a specific meaning and convey an individual message. Through the process of expression, presentation, transformation, integration, and evaluation by the helper and the counselor, the individual expressions of emotion sublimation, evaporation, and acceptance, and finally, the helper recovers and perfects his personality.
