Specific language impairment (SLI): concept and features

In this article, and given the importance that this disorder is taking nowadays, I am in the commitment to do a bibliographic review about the specific language impairment, SLI from now on. This disorder has been explained for various authors who intend to give some meaning with their contributions and provide it with clear characteristics. For that, we will see the concepts, a short classification, the educational treatment and the educational intervention that has been done. As a conclusion, I contribute a study of Van der Lely and Howard in 1993. This study aims to clear out what happened to the children who have SLI, if it is a deterioration in the language or a deficit in the long-term memory operation.
