Results suggest tight coupling between mothers’ and children’s verbal behaviors in interaction when children have normal hearing. Although mother-child interactions seem to be less synchronous when children have hearing loss, children with CIs appear to be sensitive to contingency timing and to attend to and to be partially tuning into the conversational dynamics of their mothers.

Abstract

Parent-child interactions play a central role in early developmental processes. One of the most important characteristics of these interactions, affecting both affiliative bonding and speech and language development, is the temporal coordination of the two partners or ‘synchrony’. It is unclear how synchrony of verbal behaviors is affected by hearing loss. The present work is the first to investigate verbal synchrony between 40 Italian-speaking mothers with normal hearing and their children with normal hearing (NHA; n=20) or with cochlear implants (CIs; n=20) one year after implantation (ages 1;1 - 3;11 years). Mother-child interactions during semi-structured free-play were videorecorded for 20 minutes and transcribed. Vocalizations, overlapping speech, and between- and within-speaker pauses are in the process of being manually coded using Praat. Preliminary data analysis on 10 children in each group showed positive, significant correlations between the duration of maternal vocalizations and that of children’s vocalizations (r = 0.82, p = .004) and between the duration of non-interruptive overlapping speech in mothers and children (r = 0.77, p = .026) only in the NHA group. Tests also showed that the number of children’s contingent responses (operationalized as the number of responses given within 2 seconds from the end of the other speaker’s vocalization) was significantly correlated to the number of mothers’ contingent responses in both groups (NHA: r = 0.94, p < .001; CI: r = 0.92, p < .001). Results suggest tight coupling between mothers’ and children’s verbal behaviors in interaction when children have normal hearing. Although mother-child interactions seem to be less synchronous when children have hearing loss, children with CIs appear to be sensitive to contingency timing and to attend to and to be partially tuning into the conversational dynamics of their mothers. Further analyses will help assess the validity of these results.
