A case study research on Justin Herald’s language development

The first language development of a 4-year-old was the subject of this case study. Additionally, it examines the problems and processes that influence L1 development. Over the span of two months, the researcher observed and documented the subject's generated sounds, phrases, and sentences as well as how the learner responded to various linguistic stimuli to understand how the youngster internally interpreted them. According to the findings of the study, the child's phonological development should be taken into account and more emphasis placed on assisting the child in coping with phonological awareness in the target language, particularly in critical vowels and diphthongs. The child also struggled with language and communication, which were greatly influenced by his environment. Undoubtedly, a child's early language development is greatly influenced by the environment and its surroundings. To promote practical and meaningful language learning and growth, both parents and teachers should constructively profit from them at different phases of the process of learning.
