Multimodal language in bilingual and monolingual children: gesture production and speech disfluency

Abstract

Bilingual and monolingual children might have different styles of using multimodal language. This study investigates speech disfluency and gesture production of 5- and 7-year-old Turkish monolingual (N = 61) and Turkish-English bilingual children (N = 51). We examined monolinguals' Turkish narratives and bilinguals' Turkish and English narratives. Results indicated that bilinguals were more disfluent than monolinguals, particularly for silent and filled (e.g., umm) pauses. Bilinguals used silent pauses and repetitions (e.g., cat cat) more frequently in English than in Turkish. Gesture use was comparable across language and age groups, except for iconic gestures. Monolinguals produced more iconic gestures than bilinguals. Children's overall gesture frequency predicted disfluency rates only in Turkish. Different gesture types might be orchestrated in the multimodal system, contributing to narrative fluency. The use of disfluency and gesture types might provide insight into bilingual and monolingual children's language development and communication strategies. Copyright © The Author(s), 2023.
