For many years reading and language specialists have argued about whether children with reading and learning disabilities have a general linguistic deficit or one in a specific area.
It is accepted that young children need language processing skills to meet the requirements of skilled reading. Skills in speech perception, vocabulary, short-term memory, syntax and semantics are all important language processing skills for children beginning reading.
In recent years, phonological and phonetic deficits have been considered by many language authorities to be the language deficits that most clearly distinguish weak from normal readers. There is evidence that deficits in these areas are linked to poor reading. My Department has not carried out any studies in this area.
