The Process of Language and Speech: Genetic and Environmental Factors in Language Acquisition
Overview
This reflection paper analyzes a documentary about language acquisition and speech development, examining how children acquire language through both genetic and environmental factors. The paper discusses key findings including vocabulary development in children, the role of division of labor in language evolution, and the genetic basis of language through FoxP2 gene research.
What this reflection paper covers
- Introduction discussing vocabulary acquisition in young children
- Historical and sociological origins of language through division of labor
- Finch experiment demonstrating innate language development in isolation
- Genetic analysis of FoxP2 gene and communication disorders
- Conclusion on the informativeness of documentary evidence

The Process of Language and Speech
This documentary is very educative because of the interesting issues being portrayed in the film. I am surprised that a child knows more than five thousand words by the time they are five years old. I have learned that human beings discovered language due to the division of labor, which is a societal norm. The need to give and take instructions on the division of work led to the development of language to represent the particular instructions. I also learned that a baby learns language through the mother while they are still in the womb.
The finch experiment that involved birds was used in place of the forbidden experiment that was necessary to examine whether infants develop language when left alone without prior exposure. Notably, the results from the experiment indeed showed that infants developed a language when they are isolated and left in a state without previous exposure to any language. Birds were isolated from the rest when they were young, and they learned to produce a sound that indicated a kind of communication. However, the sounds were not that of their parents, meaning they developed their way of communicating (Thomas & Palmer, 2009).
The implication of the genetic discovery on FoxP2 is that language is genetically inherited. It means that a disorder in communication can be passed down to other generations from a parent.
