Cognitive and speech development in children

Аннотация

В данной статье рассматривается развитие речи у детей с расстройствами аутистического спектра (РАС), с акцентом на трудности, обусловленные социальными, неврологическими и сенсорными факторами. Анализируется, как эти факторы влияют на овладение языком, и предлагается комплексная модель для понимания и поддержки речевого развития у детей с РАС.

However, for children with Autism Spectrum Disorder (ASD), the trajectory of speech development often diverges significantly from typical patterns. Autism, a neurodevelopmental condition, is characterized by a range of symptoms including challenges in social communication, restricted or repetitive behaviors, and sensory sensitivities [1]. These symptoms contribute to the complexity of language development in children with ASD, making speech delays or atypical language patterns a defining feature of the condition. Understanding how children with ASD acquire or fail to acquire speech remains a critical area of research, particularly as speech is a fundamental aspect of social interaction and cognitive development [4]. While much attention has been given to the early identification of autism and behavioral interventions, less focus has been placed on the unique pathways of speech development in these children. As the prevalence of autism continues to rise, it is increasingly important to investigate how neurological, sensory, and social factors interact to shape the speech development process in children with ASD [2]. This article aims to explore these factors by synthesizing existing research and proposing a framework that accounts for the multifaceted nature of speech development in children with autism. Speech development in typical children is governed by a variety of theoretical models, each offering different perspectives on how language is acquired. Children with ASD exhibit significant differences in brain structure and function, which may underlie many of the challenges they face in acquiring language. Neuroimaging studies have identified abnormalities in areas of the brain involved in language processing, such as the left hemisphere’s language areas, including Broca’s area (responsible for speech production) and Wernicke’s area (involved in language comprehension) [2]. These findings suggest that children with ASD may have altered neural connectivity, particularly in regions related to social communication and language processing, which could hinder the development of typical speech skills [5]. Moreover, sensory processing differences are a hallmark of autism. Many children with ASD experience sensory sensitivities, either hypersensitivity or hyposensitivity, to auditory, visual, or tactile stimuli [4]. These sensory differences can disrupt the way children with autism perceive and process speech sounds, leading to difficulties in understanding spoken language or producing clear, intelligible speech. For example, a child who is hypersensitive to sound may become overwhelmed by background noise, making it difficult for them to focus on conversations or follow 240 "ZAMONAVIY TILSHUNOSLIK VA TARJIMASHUNOSLIKNING DOLZARB MUAMMOLARI" mavzusidagi xalqaro ilmiy-amaliy anjuman verbal instructions. Conversely, a child with hypo-sensitivity to sound may fail to notice important linguistic cues, such as intonation or prosody, which are essential for effective communication [3]. Correlation between speech and cognition is one of the most debated topics. What is the relationship between cognition and speech and language development? Both are interrelated. One cannot function or develop without the other. Children require cognitive skills such as attention to grasp the sounds made by the mother. They need to process and store these in their long- and short-term memory for further use. They need to differentiate between sounds, build vocabu
