The basis of the method is the synergetic principle "resonance excitation" and the idea of a synergistic effect. We have developed a model of intervention based on the postulate: "The effectiveness of therapeutic intervention in the development of a child with autism and his family depends not on intensity, but on the internal nature of the child and family as a system." The idea of synergistic effect assumes that the achievements of a child with autism are fundamentally increased due to the organization of coordinated work carried out by an interdisciplinary team of escorts led by the coordinator (in contrast to the work based on the list of certain services that hold different specialists). We especially emphasize that understanding the inner nature of autism implies the need to move away from the format of individual activities with autistic children, gaining a positive experience of living with peers, and purposeful development of their social intelligence.
