Copious evidence indicates that, even in the first year of life, children’s language development is beginning and is impacted by a wide array of cognitive and social processes. The extent to which these processes are dependent on early language input is a critical concern for most deaf and hard-of-hearing (DHH) children, who, unlike hearing children, are usually not immersed in a language-rich environment until effective interventions, such as hearing aids or cochlear implants, are implemented. Importantly, some cognitive and social processes are not dependent on the early availability of language input and begin to develop before children are fitted for hearing aids or cochlear implants. Interventions involving parent training may be helpful for enhancing social underpinnings of language and for maximizing DHH children’s language learning once effective hearing devices are in place. Similarly, cognitive training for DHH children may also provide benefit to bolster language development.

The theory of embodiment postulates that cognition emerges from multisensory interactions of an agent with its environment and as a result of multiple overlapping and time-locked sensory-motor activities. In this chapter, we discuss the complex multisensory system that may underlie young children’s novel word learning, how embodied attention may provide new insights into language learning after prelingual hearing loss, and how embodied attention may underlie learning in the classroom. We present new behavioral data demonstrating the coordination of sensory-motor behaviors in groups of young children with prelingual hearing loss (deaf, early implanted children with cochlear implants and hard-of-hearing children with hearing aids) and without hearing loss (two control groups of peers matched for chronological and hearing age). Our preliminary findings suggest that individual differences and variability in language outcomes may be traced to children’s coordination of auditory, visual, and motor behaviors with a social partner.

PurposeThis study evaluated psychometric properties of 2 phonological awareness (PA) tests normed for hearing children when used with deaf and hard-of-hearing (DHH) children with functional hearing. It also provides an in-depth description of these children's PA.MethodOne hundred and eight DHH children (mean age = 63.3 months) with cochlear implants or hearing aids were assessed in the fall and spring of the school year. Sixty-three percent communicated only with spoken language; 37% communicated with both sign and speech. Examiners administered PA subtests from the Phonological Awareness Test—2 and the Test of Preschool Early Literacy, along with assessments of speech perception and early literacy.ResultsItem analyses indicated that both tests showed good psychometric properties (e.g., high item discriminations and internal consistencies). DHH children scored higher on subtests and items that measured words, rhymes, and syllables than those that assessed phonemes. Although subtest difficulty influenced the factor structure in the fall, spring PA was best characterized as a single factor. PA correlated concurrently and predictively with early literacy.ConclusionsThis study suggests that these 2 standardized tests are valid for use with DHH children with functional hearing. Although delayed, these children's PA was structurally similar to that of hearing children.

Objective This study aims to describe the effects of primary language and insurance status on care utilization among deaf or hard-of-hearing children under active otolaryngologic and audiologic care. Study Design Cross-sectional analysis. Setting Multidisciplinary hearing loss clinic at a tertiary center. Subjects and Methods Demographics, hearing loss data, and validated survey responses were collected from 206 patients aged 0 to 19 years. Two-sided t tests and χ2 tests were used to obtain descriptive statistics and hypothesis testing. Results Of the sample, 52.4% spoke primarily English at home. Non-English-speaking children and families were less likely to receive psychiatric counseling (12.2% vs 35.2% in the English group, P < .001) and reported more difficulty obtaining educational interventions ( P = .016), and 68.9% had public insurance. Parents of publicly insured children were less likely to know the type or degree of their child’s hearing loss (56.9% vs 75.4%, P = .022), and these children were older on presentation to the clinic (8.5 vs 6.5 years of age, P = .01) compared to privately insured children. Publicly insured children were less likely to receive cochlear implants ( P = .046) and reported increased difficulty obtaining hearing aids ( P = .047). While all patients reported impairment in hearing-related quality of life, publicly insured children aged 2 to 7 years were more likely to perform below minimum thresholds on measures of auditory/oral functioning. Conclusion Even when under active care, deaf or hard-of-hearing children from families who do not speak English at home or with public insurance face more difficulty obtaining educational services, cochlear implants, and hearing aids. These findings represent significant disparities in access to necessary interventions.

In this study, we investigated the perceptual function of deaf/hard of hearing children. The sample of the study consisted of 58 pupils aged 8-13 years old (3rd-6th graders) with severe (60-90 db) or profound (90 db and above) neurosensory hearing loss – pre-lingual with or without cochlear implants. Children with co-morbidity (intellectual disabilities, syndromes, autism, motor disorders, etc.) and children with post-lingual deafness/hearing impairment were excluded. In order to investigate their perceptual function, the Perceptual Functionality Criterion was used. The results of the study show that deaf/hard of hearing participants exhibit a “sporadic” profile regarding the general perceptual functionality. In particular, the participants were found to perform similarly in terms of visual-perceptive skills, while there was one exception, i.e. their visual-motor skills were worse. Higher scores have been shown in the domain of kinesthetic and tactile perception and lower ones regarding vestigial perception, especially in terms of the sense of balance. In addition, the perceptual function was investigated among the cochlear implant participants and those with conventional hearing aids. The results showed no significant differences between the two groups regarding the perceptual function, although the visual perception was found to be significantly better among the users of conventional hearing aids relative to cochlear implant users. Finally, the perceptual function was investigated in terms of the main method of language/communication used. The data indicated that participants, regardless of whether they use sign language, total/bilingual or oral communication, performed roughly similarly on the test variables. Among the different types of main method of language/communication, statistically significant differences were absent, though regarding the visual and kinesthetic perception sign language users outperformed the users of oral communication.

Radical advancements in hearing technology in the last 30 years have offered some deaf and hard-of-hearing (DHH) children the adequate auditory access necessary to acquire spoken language with high-quality early intervention. However, meaningful achievement gaps in reading and spoken language persist despite the engineering marvel of modern hearing aids and cochlear implants. Moreover, there is enormous unexplained variability in spoken language and literacy outcomes. Aspects of signal processing in both hearing aids and cochlear implants are discussed as they relate to spoken language outcomes in preschool and school-age children. In suggesting areas for future research, a case is made for not only expanding the search for mechanisms of influence on outcomes outside of traditional device- and child-related factors, but also for framing the search within Biopsychosocial systems theories. This theoretical approach incorporates systems of risk factors across many levels, as well as the bidirectional and complex ways in which factors influence each other. The combination of sophisticated hearing technology and a fuller understanding of the complex environmental and biological factors that shape development will help maximize spoken language outcomes in DHH children and contribute to laying the groundwork for successful literacy and academic 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.
