The Impact

Abstract Profound deafness during childhood affects the normal development of auditory and speech perception, speech production and language skills. Cochlear implants (CIs) have revolutionized the scenario of rehabilitation of profoundly deaf individuals. A prelingual deaf is one who is congenitally deaf or whose hearing loss occurred before speech development. The current review was undertaken to assess the impact of cochlear implants (CIs) in prelingual deaf children on their hearing and speech perception, speech production and language development.

Before And After

The primary purpose of this study was to determine if negative intraoral air pressures (−P o ) produced by young deaf children can be treated effectively with visual feedback. We used two forms of visual feedback. One was a display of the P o signal on an oscilloscope, and the other was movement of cellophane streamers placed in front of the children’s mouths. Participants were two 5-year-old boys who had been using cochlear implants (CIs) for less than 6 months. Both children were congenitally deafened and had very limited speech production and perception skills. In addition to frequent usage of −P o , both children exhibited deviant phonatory behaviors, so phonatory goals were incorporated into treatment. The magnitude and direction of P o was monitored, as well as fundamental frequency and electroglottograph cycle width. Data were collected at baseline, before and after treatment sessions, and 7 weeks after termination of treatment. One child responded well to treatment of −P o with both forms of visual feedback, and progress was maintained at follow-up. For the other child, +P o occurred more frequently as the study progressed, and he rarely produced −P o by the end of the investigation. However, because changes were evident in baseline as well as during treatment, it is difficult to attribute his more frequent use of +P o specifically to treatment. The phonation of the two children changed in ways that were consistent with their phonatory goals, although the degree of change was not always significant. Change was more evident for phonatory behaviors that could be shaped with visual feedback. Although both children exhibited some undesirable speech/voice behaviors in response to visual feedback, there was no evidence of long-lasting mislearning. Although our data are limited, it appears that treatment of −P o can be efficacious for some young children with CIs, even those with very poor speech perception and speech production skills. Further, treatment of −P o can be incorporated effectively with other speech production goals.

PurposeTo determine whether preschool-age children with cochlear implants have age-appropriate phonological awareness and print knowledge and to examine the relationships of these skills with related speech and language abilities.MethodThe sample comprised 24 children with cochlear implants (CIs) and 23 peers with normal hearing (NH), ages 36 to 60 months. Children's print knowledge, phonological awareness, language, speech production, and speech perception abilities were assessed.ResultsFor phonological awareness, the CI group's mean score fell within one standard deviation of the Test of Preschool Early Literacy's (Lonigan, Wagner, Torgesen, & Rashotte, 2007) normative sample mean but was more than one standard deviation below the NH group mean. The CI group's performance did not differ significantly from that of the NH group for print knowledge. For the CI group, phonological awareness and print knowledge were significantly correlated with language, speech production, and speech perception. Together these predictor variables accounted for 34% of variance in the CI group's phonological awareness but no significant variance in their print knowledge.ConclusionsChildren with CIs have the potential to develop age-appropriate early literacy skills by preschool age but are likely to lag behind their NH peers in phonological awareness. Intervention programs serving these children should target these skills with instruction and by facilitating speech and language development.

Introduction The mismatch negativity (MMN) is a negative long-latency auditory potential elicited by any discriminable change in a repetitive aspect of auditory stimulation. This evoked potential can provide cortical information about the sound processing, including in children who use cochlear implants. Objective To identify MMN characteristics regarding latency, amplitude, and wave area in cochlear implanted children and to identify associations among language development, speech perception and family involvement. Methods This is a descriptive, observational, cross-sectional study, which compared two groups: study group—children with cochlear implant, and control group—hearing children. The children were submitted to MMN evaluation with non-verbal tone burst stimulus, differing in frequency in sound field at 70 dBHL, with SmartEP equipment (Intelligent Hearing Systems, Miami, FL, USA). Speech perception and language development questionnaires were also applied, and the family participation in the rehabilitation process was classified. Results The occurrence of MMN was 73.3% for the control group and 53.3% for the study group. Values of latency, amplitude and area of MMN of children using cochlear implants were similar to those of hearing children, and did not differ between groups. The occurrence of MMN was not correlated to the variables of hearing, language and family categories. Conclusion Children with cochlear implants showed similar MMN responses to those of the children in the control group, with mean latency, amplitude and area of 208.9 ms (±12.8), -2.37 μV (±0.38) and 86.5 μVms (±23.4), respectively. There was no correlation between the presence of MMN and children's performance in the auditory and language development tests or family involvement during rehabilitation.

RESUMOObjetivo: Conhecer como as famílias de crianças surdas usuárias de Implante Coclear percebem o desenvolvimento de linguagem da criança e relacionar esses dados com o tempo de uso diário e a quebra do dispositivo. Métodos: Trata-se de pesquisa de caráter exploratório com abordagem quantitativa. Realizou-se um levantamento do número de crianças implantadas em um serviço de saúde auditiva de um hospital escola, entre 2013 e 2015 e para aqueles que aceitaram participar da pesquisa, aplicou-se entrevista e a Escala de Aquisições Iniciais de Linguagem (ELM) com um dos membros da família, sendo esta áudio-gravada, via contato telefônico. Resultados: Das 66 crianças implantadas neste período, 52 participaram da pesquisa, sendo que destas 51 utilizavam o dispositivo. Verificou-se que a maioria (90,4%) frequentava terapia fonoaudiológica e as famílias relataram que estimulam o desenvolvimento da linguagem das crianças em casa. Aquelas classificadas com desenvolvimento de linguagem típico receberam o implante coclear precocemente, utilizavam o implante coclear o dia todo e nunca tiveram o equipamento quebrado. Quanto à Escala ELM, foi encontrado que existem mais casos de desenvolvimento típico para linguagem receptiva do que para a expressiva. Conclusão: Houve relação entre o uso do dispositivo e o desenvolvimento típico e a quebra do equipamento com desenvolvimento atípico de linguagem. Os familiares referiram que a compreensão de linguagem encontra-se mais adequada do que a produção da fala.

Methods: The research was observational, exploratory, with quantitative approach. A survey of the number of patients implanted in a Hearing Health Service of a public hospital was done, between 2013 and 2015 and it was applied an interview and the Early language Milestone Scale with one of the family members, audio-recorded, through telephone contact. Results: Out of the 66 implanted children, 52 families participated in the research and 51 used the device. It was verified that most of the children (90.04%) were in speech and language therapy and the families stimulated language development at home. The children with typical language development got the IC early in life, used the device all day and the implant never broke. In the ELM scale, it was found that there are more cases of typical development for receptive language than for expressive. Conclusion: There was a relationship between the use of the device and typical language development and the problems in the device with atypical language development. The families see that the children show receptive language development better than the expressive language.Key words: Cochlear Implantation; Deafness; Hearing Loss; Language; Child Development

Specific Factors

Newborn hearing screening programs and early diagnosis allow deaf children to receive hearing aids and/or cochlear implants very early in life. However, even within these early intervention scenarios, deaf children remain at risk of delays in spoken language acquisition despite what is expected based on their hearing recovery scores. The first part of this chapter offers an overview of recent studies on the role of specific factors (i.e., age at diagnosis, age at cochlear implant activation, family environment, and exposure to sign language) in affecting communicative and linguistic development. The second part examines to what extent current cognitive neuroscience research is contributing to refinement of the concept of critical or sensitive periods for the development of the acoustic system and language in deaf children. Clinical and educational implications for promoting language development in deaf children are discussed.
