Preverbal Communication

The stage of communication development before the consistent use of recognizable words, typically occurring in neurotypical children between birth and approximately 12 months of age. Preverbal communication includes vocalizations (babbling, cooing), gestures, eye gaze, facial expressions, and body movements used to express needs and engage socially. Many individuals with autism spectrum disorder, intellectual disabilities, or other developmental conditions may remain at the preverbal stage well beyond the typical age range, communicating primarily through non-word vocalizations and gestures. Understanding preverbal communication is essential for designing appropriate assistive technologies and interventions that meet individuals at their actual developmental level rather than their chronological age.
