Vocabulário expressivo de crianças com diferentes níveis de gravidade de desvio fonológico

PURPOSE: to relate task performance of expressive vocabulary with the deviation severity, the age range and the reference values of the vocabulary testing used. METHODS: the sample was made up of 17 subjects with phonological deviation, with ages ranging between 3 years 5 months and 8 years 2 months. They were divided into four groups, based on the PCC analysis and classification regarding the severity grade according to Shriberg and Kwiatkowski (1982). This result allows for classifying the deviation into: severe, moderately-severe, medium-moderated and medium. The Test for Young Children ABFW - Vocabulary was applied. An analysis took place for correlation among age, severity grade for the phonological deviation and reference results of the vocabulary testing. RESULTS: children with minor phonological deviation severity obtained better results than the others, despite the majority of these results not being significant. Younger children showed lower performance than expected. CONCLUSIONS: it is possible to think that the severity of phonological deviation may influence the performance of children in this sample in the expressive vocabulary test.

O papel das variáveis extralinguísticas idade e sexo no desenvolvimento da coda silábica

PURPOSE: To investigate the influence of extralinguistic factors in the acquisition process of the post-vocalic segments /N, L, S, R/. METHODS: The research involved 170 subjects with ages between 1:2 and 3:10 years, within normal phonological development, monolingual speakers of Brazilian Portuguese. The data collected from these subjects were 3026 lexical items originated from AQUIFONO and INIFONO databanks. The roles of extralinguistic and linguistic variables in coda acquisition were investigated, however, in this article, only the results of the variables age and sex were explored. Statistical analysis used the VARBRUL package. RESULTS: Both extralinguistic factors analyzed were relevant to the process of normal phonological acquisition. Age played a statistically favorable role in the acquisition process of all phonemes in both coda positions. There was an increase in the correct production of phonemes with age, however this growth was not linear. The first productions of the rhyme VC with /L/ in final coda occurred at 1:2, while the complete mastery of all four segments licensed in coda position was gradual, and was attained in stages extended until 3:8. Among the variables considered, sex was the second most selected by the statistical program, showing significant statistical differences for the variable sex in the acquisition of codas with medial /N/, /L/ e /S/ and the final coda with /L/. CONCLUSION: It was found a higher probability of correct use of the coda as age increased, but regressions in its use were observed, which should be seen as a normal stage of the development. Regarding sex, there was a tendency for male subjects to present higher phonological precision, however, this does not mean they present different acquisition stages when compared with female subjects.

Vocabulário expressivo de crianças com desenvolvimento fonológico normal e desviante

TEMA: vocabulario expressivo de criancas com desenvolvimento fonologico normal e desviante. OBJETIVO: verificar se as alteracoes das criancas com desvio fonologico ocorrem apenas no nivel fonologico ou se ha algum impacto na aquisicao lexical e comparar o desempenho em vocabulario das criancas desta amostra com os valores de Referencia de Normalidade do teste utilizado. METODO: a amostra foi composta por 36 criancas de ambos os sexos, sendo 14 com desvio fonologico (Grupo Estudo) e 22 com desenvolvimento normal de linguagem (Grupo Controle). Foi aplicado o teste ABFW - Vocabulario (Befi-Lopes, 2000) para avaliar o vocabulario expressivo destas criancas e, apos, foi comparado o desempenho dos dois grupos. RESULTADOS: o desempenho em vocabulario expressivo das criancas com desvio fonologico e semelhante ao das criancas com desenvolvimento fonologico normal. Grande parte das criancas desta amostra atingiu os valores de referencia propostos pelo teste na maioria dos campos conceituais, e o que mais se mostrou complexo para as criancas dos dois grupos foi o Locais. CONCLUSAO: a alteracao das criancas com desvio fonologico e realmente apenas a nivel fonologico, sem impacto no aspecto lexical da linguagem.
