Art Therapy is a form of expressive therapy that uses art-making and creativity to increase emotional well-being. Art Therapy is based on the belief that the creative process involved in making art is healing and life-enhancing. Art Therapists have specialized knowledge about the psychological aspects of the creative process, especially the affective properties of different art materials and techniques. It involves using a wide variety of art materials, such as paints, clay and batik, to create a visual representation of thought and feelings. Art Therapy can be an individual activity, but is often used very successfully in group situations.
