These difficulties typically result from a deficit in the phonological components of language that is often unexpected in relation to other cognitive abilities. In addition, the difficulties are not typically a result of ineffective classroom instruction. Secondary consequences may include problems in reading comprehension and reduced reading experience that can impede growth of vocabulary and background knowledge.
