Age at Intervention for Permanent Hearing Loss and 5-Year Language Outcomes

Abstract: OBJECTIVES: Universal newborn hearing screening has been implemented to detect permanent childhood hearing loss (PCHL) early, with the ultimate goal of improving outcomes through early treatment. However, there is disagreement between studies on the size of this benefit and in some cases whether it is significantly different from 0. There have been no studies of sufficient size in which researchers have determined reliably whether the effect varies with degree of PCHL. We aimed to explore how intervention timing influences 5-year language in children with PCHL. METHODS: Via a prospective study of 350 children, we used standard multiple regression analyses to investigate the effect of age at intervention or hearing screening on language outcomes after allowing for the effects of nonverbal IQ, degree of PCHL, sex, birth weight, maternal education, additional disabilities, and communication mode. RESULTS: The benefit of early intervention for language development increased as hearing loss increased. Children whose amplification started at age 24 months had poorer language than those whose amplification started at 3 months. The difference was larger for 70-dB HL (−11.8 score points; 95% confidence interval [95% CI]: −18.7 to −4.8) than for 50-dB HL (−6.8; 95% CI: −10.8 to −2.8). Children who received cochlear implants at 24 months had poorer language than those implanted at 6 months (−21.4; 95% CI: −33.8 to −9.0). There was no significant effect of screening on outcomes. CONCLUSIONS: Early intervention improves language outcomes, thereby lending support to streamlining clinical pathways to ensure early amplification and cochlear implantation after diagnosis.

W(h)ither the Deaf Community? Population, Genetics, and the Future of Australian Sign Language

Abstract: CCORDING TO ENROLLMENTS in schools for the deaf and data from the national census and neonatal hearing screening programs, the incidence of severe and profound childhood deafness in Australia is, and has been, less than commonly assumed. Factors implicated include improved medical care, mainstreaming, cochlear implants, and genetic science. Data for the United States, Britain, and other developed countries seem consistent with those for Australia. Declining prevalence and incidence rates have immediate implications for sign-based education, teacher-of-the-deaf training programs, and educational interpreting. There are also serious consequences for research, documentation, and teaching regarding Australian Sign Language (Auslan), and for the future viability of Auslan. Prompt action is essential if a credible corpus of Auslan is to be collected as the basis for a valid and verifiable description of one of the few native sign languages in the world with significant attested historical depth.

Learning from the Longitudinal Outcomes of Children with Hearing Impairment (LOCHI) study: summary of 5-year findings and implications

Abstract: Objective: This article summarises findings of the Longitudinal Outcomes of Children with Hearing Impairment (LOCHI) study, and discusses implications of the findings for research and clinical practice. Design: A population-based study on outcomes of children with hearing loss. Evaluations were conducted at five years of age. Study sample: Participants were 470 children born with hearing loss between 2002 and 2007 in New South Wales, Victoria and Queensland in Australia, and who first received amplification or cochlear implantation by three years of age. Results: The earlier hearing aids or cochlear implants were fitted, the better the speech, language and functional performance outcomes. Better speech perception was also associated with better language and higher cognitive abilities. Better psychosocial development was associated with better language and functional performance. Higher maternal education level was also associated with better outcomes. Qualitative analyses of parental perspectives ...

Benefits of Sign Language Interpreting and Text Alternatives for Deaf Students' Classroom Learning

Abstract: Four experiments examined the utility of real-time text in supporting deaf students' learning from lectures in postsecondary (Experiments 1 and 2) and secondary classrooms (Experiments 3 and 4). Experiment 1 compared the effects on learning of sign language interpreting, real-time text (C-Print), and both. Real-time text alone led to significantly higher performance by deaf students than the other two conditions, but performance by deaf students in all conditions was significantly below that of hearing peers who saw lectures without any support services. Experiment 2 compared interpreting and two forms of real-time text, C-Print and Communication Access Real-Time Translation, at immediate testing and after a 1-week delay (with study notes). No significant differences among support services were obtained at either testing. Experiment 3 also failed to reveal significant effects at immediate or delayed testing in a comparison of real-time text, direct (signed) instruction, and both. Experiment 4 found no significant differences between interpreting and interpreting plus real-time text on the learning of either new words or the content of television programs. Alternative accounts of the observed pattern of results are considered, but it is concluded that neither sign language interpreting nor real-time text have any inherent, generalized advantage over the other in supporting deaf students in secondary or postsecondary settings. Providing deaf students with both services simultaneously does not appear to provide any generalized benefit, at least for the kinds of materials utilized here.

Principles and Practices of Literacy Development for Deaf Learners: A Historical Overview

Abstract: Since the very beginning of formal approaches to deaf education, the development of literacy has been a priority issue The history of educational initiatives in this area is entwined with the history of prevailing attitudes and practices toward the impact of deafness on the development of deaf children more generally In particular, arguments about whether a visual input (reading) can take the place of a diminished auditory input and whether educators should accommodate or seek to ameliorate the effects of the special linguistic characteristics of deaf learner-readers have resulted in a wide variety of practices and perspectives These varied practices and perspectives continue to have impacts on current educational debate and practice This article provides a brief historical overview of these educational endeavors, noting the enduring questions and issues that remain for the field to address
