Abstract
Este estudio analiza si los datos procedentes de informes parentales son una fuente de información fiable sobre el desarrollo gramatical temprano. Se trata de un estudio de validez concurrente que compara la información aportada por los padres a través la versión española de los Inventarios MacArthur-Bates con medidas tomadas a partir del habla espontánea de los 35 niños participantes. Se elaboró un protocolo observacional para evaluar el nivel de desarrollo gramatical en niños menores de 2,06 años de edad. Se analizaron las relaciones entre las puntuaciones en los inventarios, los datos procedentes del protocolo observacional y la longitud media de las emisiones (LME) producidas espontáneamente por los niños. Los resultados muestran que los informes parentales sobre el desarrollo gramatical de los niños correlacionan bien con las otras dos medidas, aunque en diferente grado. Las implicaciones de estas diferencias son discutidas en relación al problema de la medida del lenguaje en las primeras fases del desarrollo gramatical.
This study analyzes parental report data as a source of information about toddlers’ grammatical development. It is a study of concurrent validity that compares parents’ reports obtained with the European Spanish version of the MacArthur-Bates Communicative Development Inventories (CDI) with spontaneous speech measures from 35 children who took part in this study. An observational tool was developed to assess the level of grammatical development of children under 2;06. The relationship between the scores from the parental report, data from the observational tool, and the MLU (mean length of utterances) of the children’s spontaneous speech were analyzed. Results show the parental report to be highly associated with the other language measures, but to differing degrees for the different measures. The implications of these differences are discussed.
