Article: La relación entre el aprendizaje léxico y el desarrollo gramaticalThe relationship between lexical learning and grammatical development
[show abstract] [hide abstract]
ABSTRACT: El presente trabajo se centra en estudiar la relación que existe entre el desarrollo de léxico y el de la morfosintaxis. Concretamente pretendemos explorar el tipo de vocabulario que mejor predice el desarrollo de la morfología verbal y el de la complejidad gramatical, así como establecer el tipo de relación entre desarrollo léxico y desarrollo morfosintáctico. La muestra comprende 517 niños de edades comprendidas entre los 18 meses y los 30 meses. Los datos se han recogido a partir de la adaptación al catalán del instrumento MacArthur-Bates Communicative Development Inventories (CDI). Los resultados muestran que el mejor predictor del desarrollo morfológico y gramatical es el vocabulario de clase cerrada, conjuntamente con el vocabulario general. Por otra parte, se observa una relación predominantemente lineal entre el desarrollo del léxico y el desarrollo morfosintáctico.The present study focuses on the relationship between lexical and morphosyntactic development. Specifically, we intend to explore which kind of vocabulary best predicts the development of verbal morphology and grammatical complexity, and to analyse the relationship between lexical and morphosyntactic development. The sample was composed of 517 children aged from 18 months to 30 months. The data were collected by means of the Catalan adaptation of MacArthur-Bates Communicative Development Inventories (CDI). The results show that the best predictor of morphological and grammatical development is closed class vocabulary, together with general vocabulary. On the other hand, a predominantly linear relationship between lexical development and morphosyntactic development is observed.Infancia y Aprendizaje 10/2010; 33(4):435-448. · 0.40 Impact Factor -
Article: A comparative study of the phonology of pre-school children with specific language impairment (SLI), language delay (LD) and normal acquisition.
[show abstract] [hide abstract]
ABSTRACT: The phonology of two groups of SLI (n = 5) and LD (n = 5) children was analysed at age 3 and compared with two control groups: an age control (n = 5) and a language level control (measured using the MLU-W) (n = 5). Children with SLI and LD showed a delay in the acquisition of segments, syllabic structures and word structures, and in the simplification processes, compared with their age control group. However, SLI children also displayed significant differences vis-à-vis their language level controls, mainly in early acquisitions: vowels, nasals and stops at the segmental level, and in CV structures at the syllabic level. There is also a simplification process that seems to be more prevalent in these children than in their language level controls, namely, the deletion of unstressed syllables, mainly initial ones. The results enable SLI to be distinguished from LD and suggest that the development of SLI phonology is deviant. This deviation is interpreted as being a plateau in early acquisitions when later acquisitions have already appeared. The results are considered in the light of Leonard's surface hypothesis and an exclusively linguistic cause for this disorder is ruled out.Clinical Linguistics & Phonetics 01/2003; 16(8):573-96. · 0.64 Impact Factor -
Article: Phonological profile of Spanish-Catalan children with specific language impairment at age 4: are there any changes over time?
[show abstract] [hide abstract]
ABSTRACT: The phonology of a group of Spanish-Catalan children with specific language impairment (SLI, n = 5), who had been analysed at age 3;10, is now analysed at age 4;09 and compared with two control groups: an age-matched control (n = 5) and a language level control (measured using the mean length of utterance by words; n = 5). The children with SLI continue to show a delay in the acquisition of segments, syllabic structures and in the use of the simplification processes, but not in word structures, compared with their age-matched controls. Children with SLI also display significant differences compared with their language level controls, but not in the same areas as observed at age 3: the differences are now in nasals and liquids at the segmental level, and in CCV, CVC and other complex structures at the syllabic level. There are also some simplification processes that seem to be more prevalent in these children than in their language level controls: absence of trill, cluster reductions and consonant deletions. The results enable us to interpret SLI as more than a delayed development and to show the differences in the profiles over time.Folia Phoniatrica et Logopaedica 02/2006; 58(6):400-14. · 1.12 Impact Factor -
Article: Influence of phonology on morpho-syntax in Romance languages in children with Specific Language Impairment (SLI).
[show abstract] [hide abstract]
ABSTRACT: The profiles of children with Specific Language Impairment (SLI) differ greatly according to the language they speak. The Surface Hypothesis attempts to explain these differences through the theory that children with SLI will incorrectly produce elements in their language with low phonological weights or that are produced in a non-canonical prosodic structure. Previous studies have shown that the most characteristics errors produced by Catalan and Spanish-speaking children with SLI include function word omission (morpho-syntax) and weak syllable omission (phonology). The omission of function words points to a morpho-syntactic explanation of SLI, while weak syllable omission supports a phonological explanation of SLI. Yet, function words are weak syllables; thus, it is possible that the same mechanism underlies both problems. Data were extracted from spontaneous language produced by five children with SLI and five comparison children matched for age and MLU-w. They were assessed on two occasions: at 3;10 and 4;9 years of age. These interviews were then transcribed and the morphological and phonological errors coded. A non-parametric mean analysis and various regression analyses were conducted. The results show that function word omission and weak syllable omission were the most characteristic errors made by Spanish and Catalan-speaking children with SLI and established that omissions increase as prosodic weight decreases. They also indicated that weak syllabic omission may explain most function word omissions. The data support the Surface Hypothesis and suggest that the same impaired mechanism may underlie the morphological and phonological problems SLI children display.International Journal of Language & Communication Disorders 42(3):325-47. · 1.95 Impact Factor -
