What term describes the sequence of language development that begins with child-directed speech?

The sequence of language development that begins with child-directed speech is best described by the term "universal sequence and normative benchmark." This concept refers to the predictable progression and stages that children typically follow as they acquire language skills, starting from the early interactions they have with caregivers, often characterized by simplified speech patterns that are intentionally directed towards them.

Child-directed speech, or "motherese," plays a key role in this process as it is designed to capture a child's attention and make it easier for them to learn. This speech typically includes exaggerated intonation, slower pace, and clear articulation, which can encourage infants to mimic sounds and learn new words. The universal sequence outlines the various milestones, such as cooing, babbling, and the use of single words, eventually leading to more complex sentence structures. By establishing norms for language development, this benchmark aids researchers and clinicians in identifying typical versus atypical language acquisition patterns in children.

The other options either refer to specific aspects of language development or do not encompass the broader sequence and benchmarks recognized in developmental linguistics. Holophrases refer specifically to single words that convey complete ideas, while naming expansion pertains to the process of adding more complexity to a child's vocabulary through rich descriptive language. Cognitive language acquisition focuses more on
