During infant language acquisition, which outcome occurs regarding variegated babbling following canonical babbling when an infant experiences inconsistent caregiver responsiveness to their vocalizations?

💡 Explanation

Delayed variegated babbling emerges because inconsistent caregiver responsiveness disrupts the infant's ability to refine their vocalizations through feedback. This affects their transition to producing varied syllable structures, therefore delaying the expected progression, rather than promoting advanced imitative behaviors.
