(1) Gesture-based narrative trainings using non-referential beat gestures

​

These studies used a between-subjects training with a pretest and immediate posttest design to investigate whether narrative training with observing beat gestures as well as encouraging children to produce these gestures contribute to improving their narrative performance at posttest.

​

We conducted a longitudinal study that analyzes the speech and gestures produced by 45 14- to 58-months-old children in naturalistic interactions with their caregivers. Results showed that the early spontaneous production of non-referential beat gestures, as opposed to the production of referential iconic gestures and non-referential hand flip gestures, predicts later narrative abilities at 5 years of age. We also carried out a very detailed analysis of children's target sentences with co-speech gestures (beat, flip and iconic gestures) following a pragmatic coding scheme.

​

The study aims to assess the predictive value of gestures in children's narrative development by comparing the effects of referential iconic gestures and non-referential gestures produced in narrative corpora. Specifically, we investigate whether referential iconic gestures and/or non-referential gestures performed by 5- to 6-year-old children while producing narratives can signal changes in children's later narrative performance two years later. Results demonstrated that referential iconics (as opposed to non-referential gestures) that accompanied narratives produced by children at 5 and 6 years of age are significant predictors of later narrative scores two years later.
