SENSORY INTEGRATION AND ITS SIGNIFICANCE FOR CHILD DEVELOPMENT

Abstract

The article is devoted to highlighting the features of sensory integration manifestation in childhood and its significance for the holistic development of the child. This includes uncovering the characteristics and patterns of mental development during childhood, describing the main stages of sensory integration development in ontogenesis, and examining sensory integration disorders and the application of sensory integrative therapy with children. A review of foreign and domestic literature on the research problem has shown that there is a growing interest in sensory integration in modern psychology as the foundation for a child's holistic development. Sensory integration is a process occurring in the brain that organizes information received through the senses (vision, hearing, touch, smell, taste), gives meaning to these sensations by filtering information, selecting what to focus on, and enabling us to act and react thoughtfully to the situation we are in. It also forms the basis for theoretical learning and social behavior. The harmonious development of a child depends on the coordinated functioning of all sensory systems. The article explores the features and patterns of mental development in childhood, such as heterochrony, asynchrony, staging, differentiation, and integration of mental processes and properties, as well as changes in the determinants of mental development and plasticity. The main stages of sensory integration development in ontogenesis are also examined. The importance of the sensory-perceptual sphere in a child’s development is underscored, as sensory development is the foundation of a child’s intellectual growth. Sensory development involves the development of sensations and perceptions, as well as the understanding of objects' forms, colors, sizes, and spatial locations, as well as the objects and phenomena of the surrounding world. Perception is formed based on the synthesis of various sensations: visual, auditory, tactile, kinesthetic, olfactory, and others. Perception reflects the objectivity, integrity, structure, constancy of objects, and others. Early childhood is the most favorable period for the improvement of sensory organ functions and the accumulation of representations about the surrounding world. Knowledge of the surrounding reality in children begins with the analysis of information received through touch, visual observation, sounds, smells, various tastes, and so on. It has been established that childhood plays a crucial role in sensory integration, as a child organizes not only visual and auditory sensations but also the sensations of their own body and the force of gravity, which contributes to the child’s holistic development. A significant portion of a child’s learning ability lies in their ability to integrate sensory information, as learning depends on the ability to perceive and process sensations from their movements and external influences and to use this information for planning and organizing behavior. It has been found that sensory integration facilitates the development of motor skills, movement coordination, spatial orientation, and visual and auditory perception, particularly by filtering and organizing information to help the child focus on solving specific tasks. Moreover, sensory integration contributes to the development of cognitive mental processes: attention, memory, thinking, and speech. Sensory integration also enhances a child's adaptation to the environment, social interaction, communication, and the formation of independence and curiosity in the child. Sensory integration disorders (hyposensitivity and hypersensitivity of sensory systems) have been analyzed, and the main principles of sensory-integrative therapy with children have been outlined. Children with reduced sensory processing abilities often experience difficulties in carrying out voluntary actions, which in turn can affect learning and behavior. Therefore, sensory-integrated therapy aimed at developing and integrating sensations contributes to improving the child’s learning and behavior. In conclusion, sensory integration is of great importance for child development.
