Autism spectrum disorder is a neurodegenerative disorder that usually manifests itself in the early years of life and lasts throughout life. Its main features are continuous problems in establishing social interactions, verbal and non-verbal communication abnormalities, and stereotypical patterns of behavior and interest. When discussing the design of space for children in the autism spectrum, it is important to pay attention to the knowledge and understanding of how to experience the environment and objects. Describing the sensory differences of perception, processing, and response are important because children are able to learn in the mainstream of the environment. Particular attention to physical spaces is important in designing the healthcare facilities of patients with autism, because it is directly related to the learning and development of these children. Space architecture, with awareness of environmental psychology, creates an atmosphere in which the child, with regard to ethical and behavioral characteristics, as well as communication weaknesses, can undergo stress-free and stress-free rotation. The key question in this article is how can environmental stressors be reduced to a child with autism? Findings suggest that a range of constructive elements such as the color and light in space can have a significant effect on the elimination of any stimulus and stress. Therefore, the present study uses a descriptive-analytic research method to investigate the architectural features of the health-care spaces of patients with autism with the psychology of the environment. architectural features play an important role in the treatment process and enhance the focus of autistic children.
