Oral Language DisabilitiesChildren with learning disabilities may display deficits in one or more of the following areas: oral expression, listening comprehension, written expression, basic reading skills, reading comprehension, mathematics calculation, or mathematics reasoning (Federal Register, 1977). Although language is one of many areas in which a child may evidence a learning disability, the ramifications are tremendous with language, as they may be associated with problems in reading, spelling, writing, and arithmetic.
