In the context of language acquisition, the phenomenon where adults provide feedback and corrections to children's speech is known as what?

The appropriate term for the phenomenon where adults provide feedback and corrections to children's speech is expanding. This process involves adults taking a child's utterance and expanding it into a more complex or grammatically correct version. For instance, if a child says, “Doggy run,” an adult might respond with, “Yes, the big dog is running fast!” This not only models correct language use but also helps children learn structure and vocabulary in context.

Expanding is crucial because it encourages children to understand the nuances of language and provides them with grammatical structures they can emulate in their own speech. This feedback reinforces their understanding and helps solidify their language skills as they grow.

Other concepts, such as reinforcement, modeling, and imitation, play roles in language development but do not specifically refer to the act of elaborating on a child's speech. Reinforcement refers to providing positive or negative feedback based on a child's response, modeling involves demonstrating language use for the child to see, and imitation is when a child replicates what they hear. Expanding focuses explicitly on the interactive process between adult and child that effectively teaches and enriches language use.
