Young infants demonstrate a robust listening preference for infant-directed speech (parentese) over adult-directed speech, which aids in early language development and communication.

The analysis

The retrieved literature, particularly established findings referenced in the studies, consistently indicates that infants prefer infant-directed speech. Paper 1 explicitly reaffirms the well-established finding that infants listen longer to IDS, and Paper 5 notes its effectiveness in eliciting responses.
