Language processing is the ability to attach linguistic meaning of increased complexity to auditory information that is received and to then formulate a response (Richard, 2001). Children with language processing difficulties do not have difficulty hearing and they have normal/near normal basic receptive/expressive language skills. The auditory information is received accurately however the child has difficulty attaching meaning to it as the linguistic difficulty of the task increases.
