THE EFFICACY OF EARLY IDENTIFICATION AND INTERVENTION FOR CHILDREN WITH HEARING IMPAIRMENT

Abstract

From these findings, the inevitable conclusion is that identification of hearing loss by 6 months of age, followed by appropriate intervention, is the most effective strategy for the normal development of language in infants and toddlers with hearing loss. Identification of hearing loss by 6 months can only be accomplished through universal newborn hearing screening. Some questions that arise as a result of these studies include: What can one conclude from the finding that the language skills of children with mild hearing losses are no better than those with greater losses? If the finding holds up, it indicates a great need for investigations into biobehavior theories of language acquisition and into the part played by the prenatal 4 months of hearing. And it also shows a need for answering the question, When does a hearing loss begin?, because it certainly seems that all hearing losses are similar in their outcomes. Can the findings from these studies be used to benefit normally hearing children who are at risk for language delays as a result of limited language environments? Such children suffer from auditory deprivation just as surely as those with hearing losses. If the language skills of the latter children can be brought to normal range by early intervention, the same strategy may help high-risk populations. The efficacy of early intervention is just as valid for these children as it is for the children with hearing impairment. Now that the benefits of early identification of children with congenital hearing loss have been demonstrated, these benefits should be extended to all children who are at risk for language delays, with appropriate interventions applied immediately.
