Final answer:
Dr. Trahan endorses the nativist perspective of language development, which believes that language is etched into the structure of the brain.
Step-by-step explanation:
Dr. Trahan, who endorses the nativist perspective of language development, would likely believe that language is etched into the structure of the brain. This viewpoint, associated with linguist Noam Chomsky, posits that humans are born with an innate biological mechanism, often referred to as the language acquisition device (LAD), which enables them to learn language. The nativist perspective contrasts with behaviorist theories such as B. F. Skinner's idea that language is learned through reinforcement and other environmental factors. Nativists argue that the complexity of language and the speed and similarity with which children across different cultures learn to speak suggest the presence of inborn language faculties.
