Final answer:
Chomsky's Language Acquisition Device proposes that humans are biologically prewired to learn language, and this innate capacity allows language to be acquired in a consistent and predictable manner. Language acquisition is partially inborn and partially learned through interactions with the linguistic environment.
Step-by-step explanation:
Chomsky's Language Acquisition Device suggests that the answer is a. humans are biologically prewired to learn language at a certain time in a certain way.
Noam Chomsky proposed that we are born with an innate capacity to learn language, which he called the Language Acquisition Device (LAD). This mechanism allows us to learn language in a consistent and predictable manner, regardless of our cultural and linguistic background.
Research indicates that language acquisition is partially inborn and partially learned through our interactions with our linguistic environment. It also suggests that there is a critical period for language acquisition, with proficiency being maximal early in life and diminishing as people age.
