This final paper investigates how the development of speech is related to the development of motor skills in preschool children. In the introduction, it is stated that from birth, speech and motor skills are expressly important to a child. Along with them, the child develops other senses that are essential for his development. In order to see the connection between speech and motor, we have to start from the very beginning, therefore from the first to the third part we are based on speech. In the third part, we will explain what is motor ability, and in the fourth part, what are motor skills and how they develop. This study aims to examine the relationships between motor life skills and language skills in a group of preschool children and to investigate how the level of motor skills in young children is related to language skills in preschool age. The purpose of this paper is to synthesize the literature examining the relationship between motor skill development and the social interaction dimension of participation in young children. Current research examining the impact of motor skill development on social interactions in children with autism spectrum disorder will be discussed, illustrating the interdependence of developmental domains. Implications for physical therapy practice and recommendations for future research are provided.
