Play therapy for autism Play therapy is a psychological treatment for autism based on teleological theory. In cases where the child is unable to express and understand verbally, the therapist replaces language with play in which the child can express the psychological aspects of his or her body functions. In the process of play, children learn about the separation of the person and the self, and learn interpersonal and social skills to develop social adjustment. The purpose of play therapy for autism is to use the qualities of play to bring out the child’s own self-healing power, to express the inner complex, and to enable normal personality development. Art therapy for autism is generally known as drawing therapy. The purpose of art therapy is to present the repressed feelings and conflicts in the subconscious of the autistic person through drawing and its creative free expression activities, and to obtain expression and satisfaction from the process of drawing to achieve the effect of diagnosis and treatment of autism. Sensory integration therapy for autism is due to brain dysfunction, which is unable to integrate the five basic sensory stimuli such as visual, auditory, tactile, vestibular and kinesthetic sensations into an appropriate response. The purpose of autism sensory integration therapy is to provide the input of the above sensory stimuli and control them appropriately, so that the child can direct his or her own activities according to the internal drive and automatically form a compliant response, thereby contributing to the combination and unification of these senses to achieve the effect of autism treatment. Music therapy for autism can be divided into group therapy and individual therapy. The main therapeutic tools are drums and cymbals, which allow autistic children to improvise and play freely in order to achieve self-expression, liberation and self-expression. Music therapy can help people with autism focus, develop imagination, stabilize emotions, promote socialization and language interaction, and develop new leisure skills and interests.
