In his meeting with the "severely mentally disabled" child, the educator often faces behavior patterns that are completely unfamiliar to him. Between his own world and the world of this child, who stands before him, there is almost no relationship, or if there is, it is called into question.

This monograph presents, on one hand, an interdisciplinary systematic analysis of the theoretical positions from which the phenomenon of "severe intellectual disability" - "multiple disabilities" is approached, and on the other hand, it outlines fundamental psycho-pedagogical and teaching principles that will allow the reader (parent, educator, student) to understand more deeply the child with multiple disabilities and his world.
