Delayed First Language Acquisition in Deaf Children and Its Impact on Mental Lexicon Organization and Academic Success
Language acquisition plays a crucial role in cognitive development, communication, and academic success. Deaf children who experience delayed first language acquisition often face significant challenges in mental lexicon organization, which can have lasting effects on their overall language development and cognitive abilities. This paper explores how delayed language acquisition in deaf children impacts their mental lexicon organization, the cognitive repercussions, and the consequences for academic success.
Cognitive Development and Its Repercussions Language is deeply intertwined with cognitive processes such as memory, reasoning, and executive function. When first language acquisition is delayed, cognitive development is also hindered. Deaf children with limited linguistic input often exhibit delays in working memory, abstract reasoning, and problem-solving skills.

Furthermore, language serves as a medium for thought, and without early exposure, conceptual development is restricted. Research suggests that children with late language exposure struggle with complex cognitive tasks, such as understanding metaphors, forming logical sequences, and making inferences. These challenges stem from an underdeveloped linguistic framework, which impairs the ability to structure thoughts coherently and communicate effectively.
Delayed first language acquisition in deaf children significantly impacts mental lexicon organization, cognitive development, and academic success. The lack of early linguistic exposure disrupts the formation of a well-structured mental lexicon, leading to long-term difficulties in language processing and cognitive functioning. These challenges translate into academic struggles, affecting literacy, comprehension, and overall educational attainment. Early intervention, exposure to a first language (whether spoken or signed), and specialized educational support are crucial in mitigating these effects and ensuring that deaf children reach their full cognitive and academic potential.
Deaf infants need language from birth to thrive academically and socially.
