The expectation then is that oral language outcomes of children websites (A.G. Bell Association for the Deaf, National Acoustics Lab. Sign languages are languages that use the visual-manual modality to convey meaning. It is considered the first modern treatise of sign language phonetics, setting out a method of oral education for deaf people and a manual alphabet. The correlation between sign and spoken languages is complex and varies. The most obvious difference is that: a) a spoken language is produced by the Originally Answered: What are the differences between a sign language and a.

Early identification of hearing loss through universal newborn hearing screening and the use of new hearing technologies including cochlear implants make spoken language an option for most children.

However, there is no consensus on what constitutes optimal interventions for children when spoken language is the desired outcome.

Intervention and educational approaches ranging from oral language only to oral language combined with various forms of sign language have evolved.

Studies addressing early intervention will be selected in which therapy involving oral language intervention and any form of sign language or sign support is used.

Comparison groups will include children in early oral language intervention programs without sign support. The primary outcomes of interest to be examined include all measures of auditory, vocabulary, language, speech production, and speech intelligibility skills. We will include randomized controlled trials, controlled clinical trials, and other quasi-experimental designs that include comparator groups as well as prospective and retrospective cohort studies.

Case-control, cross-sectional, case series, and case studies will be excluded. We anticipate that a narrative synthesis of the evidence will be required. We will carry out meta-analysis for outcomes if clinical similarity, quantity and quality permit quantitative pooling of data. Discussion This review will provide evidence on the effectiveness of using sign language in combination with oral language therapies for developing spoken language in children with hearing loss who are identified at a young age.

The information from this review can provide guidance to parents and intervention specialists, inform policy decisions and provide directions for future research. Children, Hearing loss, Spoken language, Sign language, Outcomes, Systematic review Background Population-based newborn hearing screening has become a standard of care in the developed world to improve the developmental outcomes for children with permanent hearing loss [ 1 - 3 ].

Childhood hearing loss is one of the most common congenital disorders affecting 1 to 3 per live births [ 3 - 5 ] resulting in 1, to 1, affected children born in Canada annually [ 6 ].

Signed languages can do so many things spoken languages can’t

Hearing loss interferes with typical language acquisition and children are at risk of developing sub-optimal spoken language, and consequently poorer academic and literacy skills, than their peers with normal hearing [ 7 - 10 ]. While there is good evidence that newborn screening achieves early identification of hearing loss, the evidence for the effectiveness of screening in improving spoken language outcomes has been less convincing [ 211 - 13 ].

It is well recognized that early identification is not sufficient to improve communication skills and that intervention using hearing prostheses and early language stimulation must follow [ 114 ]. These programs can be grouped into two distinct philosophies: This review will therefore address the issue of interventions aimed at developing spoken language outcomes and will not deal with philosophical differences that exist between various stakeholders involved in supporting children with hearing loss and their families.

Despite a growing body of evidence that children with hearing loss can develop oral language skills [ 91819 ], there have been longstanding disagreements about optimal interventions when spoken language development is the desired outcome [ 20 ].

Although there is substantial and variable anecdotal evidence supporting various intervention approaches, there is little scientifically based consensus. However, this information is necessary to: From a theoretical perspective, research in neuroplasticity and critical periods of learning [ 2122 ] lend support to the theory that optimal intervention involving rich auditory and oral language stimulation should be initiated in infancy to mitigate the effects of hearing loss [ 23 - 25 ].

The expectation then is that oral language outcomes of children receiving auditory-based intervention should be better than those of children who are deprived of this intensive auditory stimulation through the addition of visual information which might slow down or interfere with spoken language acquisition.

Another body of research suggests that signed languages such as American Sign Language ASL are processed in the brain in the same manner as spoken languages, are therefore complementary, and provide a strong foundation for learning oral languages [ 2627 ].

Applying this reasoning, associations such as the Bilingual Coalition of Canada have called for access to ASL for all children with hearing loss even when parents choose spoken language as the desired mode of communication for their child.

This practice raises further questions about whether the addition of signs might promote spoken language acquisition in children with impaired hearing. Recently, the American Academy of Pediatrics concluded that baby sign language is a tool for improving communication in young children with normal hearing [ 29 ].

The uncertainty surrounding the most appropriate interventions required to achieve age-appropriate language skills is one of the major challenges facing newborn hearing screening initiatives. There is good evidence for positive spoken language outcomes from the cochlear implant literature [ 182530 ] but considerable debate continues about what constitutes optimal intervention approaches for promoting spoken language acquisition, regardless of degree of hearing loss.

In essence, the new possibilities for children due to newborn hearing screening, new technologies, and emerging evidence on using signs with normal hearing children have re-ignited the debate on best practices for children with hearing loss. Accordingly, the primary purpose of this research is to connect researchers and knowledge users to examine the evidence for the effects of various treatment options for early-identified children with hearing loss when the desired outcome is spoken communication.

The major question addressed in this proposal is specific to the components or characteristics of the intervention and the auditory and spoken language capacity of the developing child.

A review undertaken in to update the United States Preventive Services Task Force recommendations on newborn hearing screening highlighted the need for further research to demonstrate the effectiveness of the entire process of screening to intervention [ 2 ].

Inas Ontario was implementing newborn hearing screening, a review commissioned by Health Canada [ 31 ] compared outcomes for various interventions across the spectrum from oral to sign language approaches but failed to find conclusive evidence, citing study quality as an important barrier to knowledge synthesis in the field. Since this year old Health Canada review, technology has dramatically impacted pediatric hearing care such that early intervention for all children and early cochlear implantation including recently the use of bilateral implants to treat the most severe losses have become the new standards of care.

Several new studies investigating the impact of newborn hearing screening outcomes and of early cochlear implantation have been published since the review. Objectives of the review The objective of this systematic review is to answer the following question: In addition, potential moderating factors that may impact spoken language development will be investigated, if possible. Each component of the project includes stakeholders to ensure relevance of the project for parents, clinicians, and decision-makers.

Search methods for study identification A comprehensive search strategy was developed by an experienced information specialist and peer reviewed using the Peer Review of Electronic Strategies tool [ 33 ].

We will hand search recently published issues of key journals for example, Ear and Hearing, Journal of Deaf Studies and Deaf Education for additional studies not yet indexed in electronic databases.

Bell Conference as well as relevant professional websites A. Selection criteria Study designs It is anticipated that this review will include primarily non-randomized studies as well as observational studies as our previous review in this field of study yielded only one randomized controlled trial [ 31 ].

Accordingly, we will include the following study designs: Population Included studies will meet the following criteria: Studies that include only outcomes of children with developmental disabilities that involve cognitive delay in addition to hearing impairment will be excluded.

Intervention We will include studies addressing early intervention aimed at spoken language development, at least comprised of: Relevancy of papers will be assessed on the basis of the components of the approach that is, spoken language intervention with or without some form of sign language includedand not on the basis of the program label.

Outcomes Primary outcomes Primary outcomes will include all measures of listening and spoken language development including auditory skills for example, speech perception testsoral receptive and expressive vocabulary and language, speech production, and speech intelligibility. These outcomes are well supported in the recent literature as clinically relevant outcomes [ 131825 ].

However, during the broad and focused screening stages, articles will not be excluded on the basis of outcomes. Adverse outcomes Any adverse outcomes as reported in studies will be collected. Time frame Given our interest on the effects of visual sign languages on early identified children, we will only include studies published onward as previous generations of children were unlikely to receive the same standards of care related to early identification of hearing disorders and access to new hearing technologies for example, cochlear implantation.

Language For feasibility, only articles written in the English and French languages will be included. Articles in other languages will be screened at the broad screening level for potential relevance and the details of any relevant citations will be included in the final report. Data collection Study selection Once all records have been retrieved through electronic and other searching methods, they will be compiled in a Reference Manager database and checked for duplication.

All remaining citations will then be exported to the Distiller Systematic Review Software DSRan internet-based software program [ http: The correlation between sign and spoken languages is complex and varies depending on the country more than the spoken language. While recent studies claim that International Sign is a kind of a pidginthey conclude that it is more complex than a typical pidgin and indeed is more like a full sign language. Linguistics[ edit ] In linguistic terms, sign languages are as rich and complex as any spoken language, despite the common misconception that they are not "real languages".

Professional linguists have studied many sign languages and found that they exhibit the fundamental properties that exist in all languages. While iconicity is more systematic and widespread in sign languages than in spoken ones, the difference is not categorical.

They have complex grammars of their own and can be used to discuss any topic, from the simple and concrete to the lofty and abstract. Sign languages, like spoken languages, organize elementary, meaningless units called phonemes into meaningful semantic units.

These were once called cheremes from the Greek word for "hand" in the case of sign languages, by analogy to the phonemes from Greek for "voice" of spoken languages, but now also called phonemes, since the function is the same.

This is often called duality of patterning.

As in spoken languages, these meaningless units are represented as combinations of features, although often also crude distinctions are made in terms of handshape or handformorientationlocation or place of articulationmovementand non-manual expression. Common linguistic features of many sign languages are the occurrence of classifiersa high degree of inflection by means of changes of movement, and a topic-comment syntax.

More than spoken languages, sign languages can convey meaning by simultaneous means, e. Though there is still much discussion on the topic of iconicity in sign languages, classifiers are generally considered to be highly iconic, as these complex constructions "function as predicates that may express any or all of the following: Across the field of sign language linguistics the same constructions are also referred with other terms.

Today, linguists study sign languages as true languages, part of the field of linguistics. Relationships with spoken languages[ edit ] Sign language relief sculpture on a stone wall: Instead, sign languages, like all natural languages, are developed by the people who use them, in this case, deaf people, who may have little or no knowledge of any spoken language. As a sign language develops, it sometimes borrows elements from spoken languages, just as all languages borrow from other languages that they are in contact with.
