Language development refers to the words, their pronunciation, and the methods of combining them for the understanding of the others.Language development concerns itself with the length and the patterns of sentence structure, grammatical construction, and syntax.Heredity and environment interact to influence the development of skills in all areas, be it the development of language, cognitive, physical, or social skills. Children acquire language since they are genetically predisposed to do so and the environment also plays a significant role in it as language development is a product of both heredity and environment.The learner-centered and low-anxiety classroom environment has a great impact on language acquisition. By this, they will show a greater motivation to read aloud in class or write an essay without the fear of being criticized.The biological/hereditary factors include the genetic make-up of the child and the maturational timetable. Basic to learning a language is the ability to listen and produce sounds.The following three facts point out that we are biologically predisposed to acquire language:Firstly the human body, as you have read, is equipped for the purpose of speaking, hearing, and understanding language.Secondly, all newborns are most responsive to the sound of the human voice which shows that we have an inborn ability to learn the language.Thirdly, all children go through the same stages while acquiring language and they do so at approximately the same ages, irrespective of the language they speak. Hence, it is clear that both (A) and (R) are false.
