“…That is, a frequent explanation for deaf children's delays in language development, social development, and academic achievement is that their hearing losses prevent their acquiring knowledge relevant to those domains by overhearing the conversations of others as well as communication aimed at them (De Raeve, 2016;Holcomb, 2013;Marschark & Hauser, 2012). Although it is difficult to quantify the effects of overhearing the language of others (or not), findings indicating rapid growth in vocabulary following cochlear implantation among deaf children have suggested that the improved hearing provided by cochlear implants (CIs) might be of significant benefit to incidental learning (Connor, Craig, Raudenbush, Heavner, & Zwolan, 2006;Hayes, Geers, Treiman, & Moog, 2009). Neither CI use nor age of implantation has been found to provide significant long-term benefits to vocabulary or world knowledge (Convertino, Borgna, Marschark, & Durkin, 2014), but the potential for improved hearing and spoken language interactions with diverse others may provide benefits to the development of social maturity.…”
