The use, acquisition, development and processing of language is a widely researched topic from perspectives such as linguistics, psychology, neurosciences, etc. Its study is decisive not only because it allows us to know how humans communicate and the characteristics of their communication code, but also because through language we can explain human thought and knowledge. Proof of the importance of language is the large number of disciplines that come together in the task of studying it: from linguistics, through philosophy, psychology, neurosciences, phonology, to computer science.

​

The prominence that the area of cognitive linguistics has acquired has not only resulted in radical changes in the theories that try to explain the mind and cognitive development, it has also had an impact on other areas, such as education or artificial intelligence; allowing it to be an important point of reference for the development of computer languages, the improvement of school learning systems, in which practically all the knowledge related to communication or language learning or the clinical area that, where a greater understanding on language acquisition and development is used for the prevention and treatment of language disorders and deficits.

• social welfare. The contributions made by cognitive linguistics, with its various research areas, are vast, with the potential to impact all spheres of the population: from children and people in typical conditions, who benefit from knowledge about the factors that optimize the processes of acquisition, development and use of language; to people at risk, with language alterations or with the use of non-oralized language, who obtain benefits from scientific developments in the matter.

• Diagnosis and prognosis of language disorders. The new advances in the use and processing of language, as well as the different perspectives from which the phenomenon is addressed (such as psychology and neurosciences) offer more and more elements to establish more precise diagnoses and earlier prognoses of language disorders. , therefore also more complete and better targeted interventions.

• Education and Cognitive Linguistics. Beyond the importance of language in all facets of human life, the key role in education is decisive, not only in understanding the cognitive aspects of human oral communication or its implications for learning, but also also because their knowledge lays the foundations for a better understanding of the acquisition and development of written language, as well as for attention to other forms of communication, such as sign language or that which occurs in cases of communication disorders. For example, based on the knowledge that is being generated, the creation of applications that allow stimulation and facilitate learning in the linguistic and school development of children is contemplated.

• Nature of mind and behavior. Language is, par excellence, the most important reference on mental functioning and structure. Its study allows us to understand human thought, either assuming that language is a reflection of this thought, but also, depending on the perspective, assuming a transcendent influence of language (and languages in particular) on human thought and behavior.
