Language researchers agree that our language development progresses from babbling to the one- word stage through the two-word, telegraphic speech stage. However, Researchers have disagreed about how we acquire language and move from stage to stage.

Part A: Provide an example of language acquisition that supports the claim that we acquire language through operant conditioning:

Part B: Provide an example of language acquisition that supports the claim that we acquire language because of Chromsky’s “inborn universal grammar” theory. Your example should use the following ideas in the correct context:
• Language acquisition device
• Universal grammar
• Overgeneralization
