When Little Lisa says "Color dat ball," and her father responds with "What color is the ball?" what linguistic technique is being used?

The situation described showcases the technique of recasting, which involves rephrasing or restating a child's utterance in a more grammatically correct or complete form. When Little Lisa says, "Color dat ball," her father’s response, "What color is the ball?" serves to both correct and expand upon her original statement without directly pointing out any mistake. This technique helps children learn proper language structure and vocabulary by providing them with clearer and more accurate language examples while keeping the conversation natural and engaging.

In this context, while modeling could also refer to demonstrating proper speech, recasting specifically highlights the child's speech and offers a constructive response aimed at enhancing their language development. Shadowing and imitation involve more direct copying or repetition of a child's words, which is not the case in this scenario where the father rephrases Lisa's statement instead of simply echoing it.
