    Proceso de adaptación de los Inventarios de Desarrollo Comunicativo MacArthur-Bates al castellano estándar del Perú
    (Pontificia Universidad Católica del Perú. Fondo Editorial, 2019-12-27)
    We present here the adaptation process of the MacArthur-Bates Communicative Development Inventories (CDI) to the standard Peruvian Spanish and the version of the inventories resulting from this process. These are a tool for the study of early communication (gestures and vocalizations), the initial vocabulary and the first grammatical constructions, for children between 8 and 15 months and children between 16 and 30 months of age. Having a version adapted to Peruvian Spanish will enhance the development of research on early development issues in our country, especially, but not only, linguistic and communicative aspects. In the applied sphere, these inventories are used to detect possible language and developmental disorders. They are, then, indispensable tools, of proven reliability and validity, to measure the communicative development of our children.

    ¿Qué comprenden y dicen los niños peruanos en la primera infancia? Resultados preliminares de tamaño y composición del vocabulario entre los 8 y los 30 meses de edad
    (Pontificia Universidad Católica del Perú, 2021-12-15)
    We analyzed the size and composition of the receptive and productive vocabulary of Spanish-speaking Peruvian children in two age groups: 8 to 15 and 16 to 30 months. We look for significant changes in size based on the age and gender of the children. Regarding the composition of the vocabulary, we consider only those items that occupy the first 50 positions as long as they are understood or produced by at least 50% of the children, and we analyze them on the basis of an exhaustive list of grammatical categories and the children´s age. Finally, we explore the existence of correlations between certain grammatical categories whose syntactic relations could suggest a parallel development, and we compare our results with those of similar studies.
