Title: Spoken word learning in infants with hearing loss: The role of parent interactions.

Abstract: Language serves as a foundation for social and cognitive development. As compared to normal hearing (NH) peers, many deaf infants with hearing aids (HAs) and cochlear implants (CIs) display speech and language delays throughout childhood. Predictors for speech and language performance include, for example, age at implantation (Houston & Miyamoto, 2010), amount of residual hearing (El-Hakim et al., 2001), and communication mode (Kirk, Miyamoto, Ying, Perdew, & Zuganelis, 2000). After accounting for these factors, considerable individual differences remain. In the present study, we investigated the role of parents’ scaffolding of attention on hearing-impaired infants’ novel word learning. Previous research indicates that NH infants’ early word learning is facilitated when parents’ labeling of novel objects is synchronized with infants’ self-directed looking and touching of the novel objects (Yu & Smith, 2012). For hearing-impaired children, research indicates that parents use more directive parenting styles than parents of NH children(Meadow-Orlans, 1997). We predict that parent-infant coordination of looking and touching behavior may be influenced by the infants’ hearing status and that differences may be predictive of infants’ word learning.
