Laughter Responsiveness and Acoustic Alignment in Parent-Child and Adult-Adult Interaction

Résumé

While alignment in laughter production has been shown in adults, its presence in children remains understudied. We examined laughter responsiveness and acoustic alignment in middle childhood, comparing parent-child and parent-adult computer mediated conversations. While no significant differences were found in laughter frequency, antiphonal laughter was less frequent in parent-child interactions, despite intra-dyadic balance. Acoustic analysis revealed an increase in low-frequency spectral modulations in antiphonal laughter. To test whether this was due to local alignment with the preceding laughter, we compared distances from genuine and pseudo-random initiating antiphonal laughter pairs. In parent-adult interactions, genuine laughter pairs exhibited greater acoustic similarity than pseudorandom pairs, a pattern absent in parent-child interactions. Our study contributes to discussions on alignment theories and the role of laughter in pragmatic development.
