The term autism comes from the Greek word autos meaning I. The term itself denominates conditions under which a person does not have any social interaction or, in other words, isolates itself to be alone. It is primarily a socialization and communication disorder. The word autism was first introduced by dr. Leo Kanner in 1943 and dr. Hans Asperger in 1944. They were the first to explain the term itself and because of them an autistic person today is considered to be a person with difficulties in communication, behaviour and social interactions. Our intention was to turn theory into practice through kindergarten activities by setting autism-adjusted tasks. We noted and documented the present state and the state after the programme was completed. The programme itself was based on the development of verbal and non-verbal communication, visual functions, social interactions and the elimination of unwanted behaviour. We have reached positive results through individual work with an autistic boy, consultation with his teacher and his kindergarten friends. At first, the boy rejected any cooperation, though with time, he let us reach some results. Therefore, it has been concluded that autistic persons need more time to start communication and to open up to a new, previously unknown person. Autistic children have difficulties in non-verbal communication. They tend to avoid eye contact. Not being focused on attracting attention to certain details, they do not share interests with others. Furthermore, they are unable to immitate voices, gestures as well as determining their meanings. The inability of immitation occurs in the development of children with diagnosed autistic stages. Therefore, it is necessary, with motivating children, to make the learning of immitation interesting so that they can learn how to immitate movements and play. The most intense period of speech and language development occurs in the first three years of a child's life in anticipated phases. The child goes through phrases from the first scream and vocalisation to conscious participation in conversation in which the child expresses his or her thoughts, feelings, attitudes and needs.
