Decoding the biology of language and its implications in language acquisition
- 8 Downloads
Associating human genetic makeup with the faculty of language has long been a goal for biolinguistics. This stimulated the idea that language is attributed to genes and language disabilities are caused by genetic mutations. However, application of genetic knowledge on language intervention is still a gap in the existing literature. In an effort to bridge this gap, this article presents an account of genetic and neural associations of language and synthesizes the genetic, neural, epigenetic and environmental facets involved in language. In addition to describing the association of genes with language, the neural and epigenetic aspects of language are also explored. Further, the environmental aspects of language such as language input, emotion and cognition are also traced back to gene expressions. Therefore, effective language intervention for language learning difficulties must offer genetics-informed solutions, both linguistic and medical.
