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.

Deaf and hard-of-hearing (DHH) children born to hearing parents have profound theory-of-mind (ToM) delays, yet little is known about how providing hearing assistance early in life, through cochlear implants and hearing aids, influences their ToM development. We thus addressed (a) whether young DHH children with early hearing provision developed ToM differently than older children did in previous research and (b) what ToM understandings characterize this understudied population. Findings from 84 three- to six-year-old DHH children primarily acquiring spoken language demonstrated that accumulated hearing experience influenced their ToM, as measured by a five-step ToM scale. Moreover, language abilities mediated this developmental relationship: Children with more advanced language abilities, because of more time using cochlear implants and hearing aids, had better ToM growth. These findings demonstrate the crucial relationships among hearing, language, and ToM for DHH children acquiring spoken language, thereby addressing theoretical and practical questions about ToM development.

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.

Examining the importance of morphosyntax comprehension in literacy acquisition across languages, this chapter will highlight the bilingual and bimodal advantages some deaf and hard-of-hearing (DHH) learners may possess. Since DHH readers may experience variations in hearing, language, and literacy levels, we examine the interplay of how they develop literacy skills. The complexity of the interplay among the components of reading and writing are considered along with the current research on morphosyntax interventions and assessments for this population of learners. Morphosyntax components that are historically challenging for DHH learners are discussed. Potentially promising practices across morphology and syntax are reviewed, as well as implementations for practice that include an informal assessment designed for DHH learners. Future research necessary to expand our knowledge of how morphology and syntax connect to text is included as a call to action in the quest to improve literacy outcomes for DHH readers.

This article provides an overview of the workings of an oral school for children who are deaf or hard of hearing. The key features of the school include low student-teacher ratios, teachers who are trained as oral educators of deaf children, ongoing staff and parent education, specialized curricula, and a strong emphasis on listening and speaking throughout the day. Approximately 75% of the students at the school use cochlear implants; the remainder wear hearing aids. The graduates of this program have shown that an oral school can help many children who are deaf or hard of hearing achieve success as oral communicators and students in mainstream classrooms.

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.

Purpose We review the evidence for attenuating visual input during intervention to enhance auditory development and ultimately improve spoken language outcomes in children with cochlear implants. Background Isolating the auditory sense is a long-standing tradition in many approaches for teaching children with hearing loss. However, the evidence base for this practice is surprisingly limited and not straightforward. We review four bodies of evidence that inform whether or not visual input inhibits auditory development in children with cochlear implants: (a) audiovisual benefits for speech perception and understanding for individuals with typical hearing, (b) audiovisual integration development in children with typical hearing, (c) sensory deprivation and neural plasticity, and (d) audiovisual processing in individuals with hearing loss. Conclusions Although there is a compelling theoretical rationale for reducing visual input to enhance auditory development, there is also a strong theoretical argument supporting simultaneous multisensory auditory and visual input to potentially enhance outcomes in children with hearing loss. Despite widespread and long-standing practice recommendations to limit visual input, there is a paucity of evidence supporting this recommendation and no evidence that simultaneous multisensory input is deleterious to children with cochlear implants. These findings have important implications for optimizing spoken language outcomes in children with cochlear implants.

Strong language skills are linked to children’s literacy and social and emotional outcomes, and they are critical for educational success throughout life. However, many children who are deaf and hard of hearing (DHH) experience challenges with developing language and literacy outcomes that are commensurate with their peers with typical hearing. In particular, some children who are DHH have difficulties in understanding and using language in social contexts, specifically in regard to the more subtle and complex pragmatic skills such as contingency, inferencing, topic maintenance, and repair. This chapter suggests that such challenges evident in natural conversations may impact children’s reading comprehension. It further explores the interplay between pragmatic skills, Theory of Mind, and the complex inferential and metacognitive skills required for reading comprehension in children and young people who are DHH. Finally, the chapter addresses the implications of these links and suggests future directions for research.

Recent improvements in cochlear implants (CIs) and hearing aid technology are providing deaf children better access to sounds, yet many children with CIs and digital hearing aids continue to experience significant difficulties in verbal language learning, reading, and writing. It has been shown that explicit and intentional memory processes, like verbal rehearsal or semantic organizational strategies, can explain the language and literacy outcomes of CI and hearing aid users. More recently, however, researchers have suggested also an involvement of implicit memory, and particularly implicit sequence learning (SL), in the language and literacy delay of these children. This chapter reviews and discusses studies bringing evidence of the involvement of inefficient explicit memory processes and implicit SL in the language and literacy development of children with CIs. It is argued that the interaction between explicit and implicit memory processes (verbal rehearsal and implicit SL) can better account for CI users’ problems with language and literacy acquisition.
