Abstract
This study examined the effect that bimodal interference has on the language development of hearing children of hearing-impaired mothers. Twenty-six children, between 24 months and 74 months, were given a battery of tests. None of the children was receiving intervention by a speech pathologist. Analysis of the children's oral language skills showed that the children used sentence constructions which can be related to the influence of either the manual sign language or the oral English language. Some structures have stemmed from neither language and were idiosyncratic for that child. This study has identified probable bimodal interference effects as characteristic of the language development of hearing children of hearing-impaired mothers.
