Veinticinco años reformulando el concepto del lenguaje en psicolingüística clínica y en logopedia

In this ephemeric issue for the 25th year of the Revista de Logopedia Foniatría y Audiología publication, the author offers a brief and critical summary of the evolution of the concept of Language in this field. In this critical review the author values the evolution of formalistic and idealistic postures towards a more functionalistic point of view, integrated in the cognitive neuropsychology. The reasons of dissatisfaction are revised, including the limits of some current innovations. Finally, and focusing in the Specific Language Impairment (SLI), a new causal model is outlined in order to help its evaluation and intervention, and also as a working frame for future research.
