Biological Theoretical Perspective

The biological theoretical perspective comes from a man named Noam Chomsky. He believed that all children have a language acquisition device. This is defined in the book as “a biological endowment enabling the child to detect the features and rules of language, including phonology, syntax, and semantics”. The evidence found was that throughout cultures, children tend to have the same language milestones. Most begin at age two to four months by cooing and develop at 13 months with their first words.
The environmental perspective talks about how the environment and their parents affect how the children talk. Roger Brown determines that children learn what words mean through the way that parents are responding to them. He defines terms like

recasting, expanding, and labeling that helps restate, rephrase, and identify things from the children’s simple sentences they say. Betty Hart and Todd Risely found some evidence to prove that language is more environmental through their research on children in welfare homes and children in professional homes. The children in professional homes had a wider vocabulary and the professional parents talked to their children more.
The interactionist view focuses on the importance of biology and environment. They think that “every child benefits enormously from opportunities to talk and be talked with”. This evidence is show through a rich verbal environment with children reaps many positive outcomes, and it is important that the parents pay attention and are involved with the child’s learning or speaking.
I think that I would agree most with the interactionist view because I agree with the environmental position, but it is important to acknowledge the parts of speech that happen on their own biologically. I agree that outside sources can affect the child’s learning, and that they can learn from imitation and soaking up information from others around them. I also agree with the language milestones that children to have certain age ranges that they have similar speaking patterns. The interactionist view takes both of these perspectives into account and combines them.
