Сomprehensive support of children with autistic spectrum disorders

Today, autism is a significant social problem that is becoming more widespread, affecting children who have the same type of developmental problems, but with different options for overcoming them. This is what causes the idea of autism as a set of autism spectrum disorders. Children with ASD are a polymorphic group, which manifests itself in psychological and pedagogical features, which complicates social adaptation. In psychological and pedagogical terms, children with ASD are allocated to a special group, since interaction is built differently due to qualitative communication disorders. In many cases, children with ASD who come to school have unformed learning behaviors. For the successful development of the program material in children with ASD, it is necessary to form a stereotype of educational behavior, on which all school education is based. Deficits in the formation of these skills can lead to a longer period of adaptation of the child in school and to difficulties in mastering the program. In this article, we consider the necessary skills, the formation of which is aimed at psychological and pedagogical assistance to a child with ASD in preparation for school.

Selecting Program Material by Audio Features for Low-Frequency Perceptual Evaluation of Loudspeakers

The program material is of great importance for the results of the listening tests on loudspeakers, while the process of how to select the program material remains ambiguous. This paper investigates the criterion for selecting programs suitable for low-frequency perceptual evaluation based on the audio features of the program. A listening test was conducted to identify the more discriminating and revealing programs in the low-frequency range. Based on the listening test results, various characteristics of the programs, including dynamic, timbral, rhythmic, and spectral features, were extracted. Their relationships with the program’s discrimination ability are discussed. The results suggest that programs with a slow and clear rhythm and a smooth and even spectrum in the whole band are more discriminating in detecting the spectral differences in the low frequencies. By using these significant features, a discriminant analysis was performed to predict the ability of the program to reveal the spectral irregularities. The predictive accuracy of the derived discriminant function was 95% in separating the discriminating and undiscriminating programs.
