Piaget believes that language development is guided by and reflected in cognitive development. Therefore, the development of language depends on the development of thinking. Unlike Piaget, Vygotsky believes that the rapid growth of language increases an individual's ability to participate in social dialogue while performing tasks that are culturally meaningful.Verbal intelligence as one of the multiple intelligences has a great impact on how people communicate and interact with each other. The purpose of this study is to investigate the effect of language development on increasing and expanding linguistic intelligence in the fields of verbal and practical intelligence.For this purpose, 24 students of Hekmat Elementary School in Mashhad who met the entry and exit criteria were selected and randomly selected in two groups of 12 experimental and control. The experimental group was cognitive based on language development in the form of verbal intelligence and intelligence. Received practice and the control group had no special training. The results of independent t-test showed that students' performance in tests of both types of intelligence in the experimental group was significantly different from the performance of students in the control group. The results of this research can be useful for teachers of different languages and measuring students' linguistic and practical intelligence in order to better learn that language.
