Este artículo pretende identificar los modelos teóricos que describen el desarrollo de la narrativa oral en niños y establecer cuáles componentes del lenguaje influyen en dicho proceso. Con este propósito, llevamos a cabo una revisión sistemática de las investigaciones más recientes sobre este tema (2000-2019). Analizamos 10 estudios longitudinales que reportan resultados de medidas del lenguaje y la narrativa oral tomados durante el seguimiento de una población de niños y niñas por un periodo de al menos 12 meses. Estas medidas son la conciencia metalingüística, el lenguaje estructural y el discurso narrativo, entre otras. Nuestros resultados indican que la habilidad de contar un relato es uno de los mejores predictores del desarrollo del lenguaje en la etapa preescolar y del aprendizaje de la lectoescritura en la edad escolar. También encontramos que los modelos para explicar este proceso son escasos y que ignoran con frecuencia el componente pragmático.
SATReLO is a tool for the creation of customized applications that support language therapy for children with hearing disabilities. These applications consist of video games that replicate therapeutic activities. Video games can motivate children to embrace therapy positively, increasing the time they dedicate towards this therapy, especially at home. SATReLO allows therapists to customize video games according to the needs of each patient and it keeps a record of his or her progress over time. SATReLO contains a software product line, which makes it possible to derive new video games in real time. The process of testing the system, both in terms of functionality and usability, was thorough and allowed many details of its operation to be fine-tuned. Preliminary tests about the impact of the video games in therapeutic process have been very positive.
