Final answer:
BF Skinner emphasized that language is acquired through reinforcement or feedback, such as parental approval or being understood. Language development is a combination of nature and nurture, as it is partially inborn and partially learned through interactions with the linguistic environment.
Step-by-step explanation:
BF Skinner emphasized that language is acquired through reinforcement or feedback. He believed that language learning occurs when individuals receive approval or understanding in response to their attempts at communication. For example, when a child asks for juice and says 'me juice,' their mother giving them a cup of apple juice reinforces their language development. Skinner's theory suggests that language is acquired through a combination of nature and nurture, as it is partially inborn and partially learned through interactions with the linguistic environment.
