<p style="text-align: justify;"><strong>Objectives. </strong>The variability of disorders in the formation of dialog skills of preschoolers with autism spectrum disorders (ASD) does not always depend on the level of intellectual development. In issues of speech development, it is important to take into account both the specifics of understanding the reversed speech at the level of interrogative statements, and the aspects of structuring and semantics of the answer proposed by the child with ASD himself. In order to study the specifics of mastering the basic conversational skills by children with ASD who have unimpaired intellect, a special pilot study was designed and conducted.</p> <p style="text-align: justify;"><strong>Methods.&nbsp;</strong>The peculiarities of understanding questions of various purposes and structures by students of the age of 5&mdash;7 years (group 1 &mdash; 51 children) with unimpaired intellect and ability of verbal communication were studied. Children of group 1 and preschoolers of group 2 of younger age (from 3 years 10 months to 5 years 2 months, a total of 28 participants) were presented with 48 questions, hierarchically organized based on ontogenetic patterns associated with the formation of cognitive concepts, which are accessible to a typically developing child by a certain age. The results obtained in both groups were compared.</p> <p style="text-align: justify;"><strong>Results.&nbsp;</strong>Only 2.3% of the proposed 3,708 questions remained unanswered, and the number of correct (adequate) answers, depending on age, tended to increase (for example, preschoolers with ASD of 4 years gave 68% correct answers, preschoolers of 5 years &mdash; 73%). The study shows that, in terms of nature and specifics of dialog skills, students with ASD 5-7 years old have no significant differences from the typically developing preschoolers of a younger age group: the number and quality of correct answers from children with ASD at the age of 6 years is comparable with the number of correct answers from typically developing preschoolers of 4 years old.</p> <p style="text-align: justify;"><strong>Conclusions.&nbsp;</strong>In the process of forming dialog skills in the structure of developmental education for children with ASD, the teacher should rely solely on the traditional spontaneous question-and-answer method, they should also consider the semantics and pragmatics of the proposed lexical material. The data obtained will be useful for special education teachers in selecting the content for speech development, taking into account the individual typological characteristics of children with ASD.</p>
