ABSTRACT: In the largest, longitudinal study of young, deaf children before and three years after cochlear implantation, we compared symbolic play and novel noun learning to age-matched hearing peers. Participants were 180 children from six cochlear implant centers and 96 hearing children. Symbolic play was measured during five minutes of videotaped, structured solitary play. Play was coded as "symbolic" if the child used substitution (e.g., a wooden block as a bed). Novel noun learning was measured in 10 trials using a novel object and a distractor. Cochlear implant vs. normal hearing children were delayed in their use of symbolic play, however, those implanted before vs. after age two performed significantly better. Children with cochlear implants were also delayed in novel noun learning (median delay 1.54 years), with minimal evidence of catch-up growth. Quality of parent-child interactions was positively related to performance on the novel noun learning, but not symbolic play task. Early implantation was beneficial for both achievement of symbolic play and novel noun learning. Further, maternal sensitivity and linguistic stimulation by parents positively affected noun learning skills, although children with cochlear implants still lagged in comparison to hearing peers.

ABSTRACT: PURPOSE: To evaluate joint engagement (JE) in age-matched children with and without hearing and its relationship to oral language skills. METHOD: Participants were 180 children with severe-to-profound hearing loss prior to cochlear implant surgery, and 96 age-matched children with normal hearing; all parents were hearing. JE was evaluated in a 10-minute videotaped free play task with parents. Engagement states ranged from the lowest (unengaged) to the highest level (symbol-infused coordinated). Standardized language measures were administered. RESULTS: Multivariate analyses were conducted between the groups, stratified by chronological and language age. Children who were deaf (Deaf) spent less time in total symbol-infused JE than children with normal hearing (NH) across all ages. The majority of the Deaf group (83%) fell in the lowest language age group, in comparison to 35% of the NH group, and spent significantly less time in symbol-infused JE than hearing children. These delays were also observed in the Deaf group, who fell into the 18-36 month language age. No children in the Deaf group had achieved a language age of > 36 months. CONCLUSIONS: Young children with and without hearing had different developmental trajectories of JE, which were related to oral language skills.

3 Article Effects of maternal sensitivity and cognitive and linguistic stimulation on cochlear implant users' language development over four years. 2013

ABSTRACT: OBJECTIVES: To examine the effects of observed maternal sensitivity (MS), cognitive stimulation (CS), and linguistic stimulation on the 4-year growth of oral language in young, deaf children receiving a cochlear implant. Previous studies of cochlear implants have not considered the effects of parental behaviors on language outcomes. STUDY DESIGN: In this prospective, multisite study, we evaluated parent-child interactions during structured and unstructured play tasks and their effects on oral language development in 188 deaf children receiving a cochlear implant and 97 normal-hearing children as controls. Parent-child interactions were rated on a 7-point scale using the National Institute of Child Health and Human Development's Early Childcare Study codes, which have well-established psychometric properties. Language was assessed using the MacArthur Bates Communicative Development Inventories, the Reynell Developmental Language Scales, and the Comprehensive Assessment of Spoken Language. RESULTS: We used mixed longitudinal modeling to test our hypotheses. After accounting for early hearing experience and child and family demographics, MS and CS predicted significant increases in the growth of oral language. Linguistic stimulation was related to language growth only in the context of high MS. CONCLUSION: The magnitude of effects of MS and CS on the growth of language was similar to that found for age at cochlear implantation, suggesting that addressing parenting behaviors is a critical target for early language learning after implantation.
