- Habilidades metafonológicas em crianças com transtorno fonológico: a interferência da idade e da gravidade(2014) WERTZNER, Haydée Fiszbein; PULGA, Marina Jorge; PAGAN-NEVES, Luciana de OliveiraPurpose The objective of the present study is to assess the metaphonological skill levels of children with speech sound disorders as a function of age and disorder severity as assessed by the Lindamood Auditory Conceptualization Test (LAC-3 adapted to the Brazilian Portuguese language). Methods Fifty children with speech sound disorder between the ages of five years and seven years and 11 months were given three versions (I-A, I-B and II) of the Lindamood Auditory Conceptualization Test and then divided by age and speech sound disorder severity assessed by Percentage Consonants Correct-Revised (PCC-R) scores. Results The skills testing results indicate that younger children with 85% PCC-R or less experience greater difficulty than the other children with auditory perception and exhibit more disorganized phonological systems, as shown in their execution of simple metaphonological skills throughout testing, which involve discriminating between isolated phonemic units. The complex task results do not provide sufficient information to determine which cognitive-linguistic knowledge features among children with speech sound disorder are most heavily affected. Conclusion The skills testing results indicate that children with more severe speech sound disorder, who thus present higher degrees of phonological system disorganization, experience greater difficulty in the area of auditory perception. The results further indicate that regardless of the degree of disorder severity, children with phonological disorders struggle with more complex metaphonological skills, and those with greater degrees of disorder severity also struggle to master simpler metaphonological tasks.
- Aplicação de medidas de gravidade e de inconsistência de fala em crianças com transtorno fonológico(2013) WERTZNER, Haydée Fiszbein; PEREIRA, Karina; SILVA, Thaís Zemlickas; PAGAN-NEVES, Luciana de OliveiraPURPOSE: To describe the severity indexes PCC-R, IRS, IRO, IRD, PDI and SII in children with speech sound disorder with and without the phonological process of devoicing and verify its efficiency in identifying differences among children. METHODS: This is retrospective and cross-sectional study involving 20 children with speech sound disorder between 5 and 8 years-old. Two subgroups were created according to the presence of the phonological process of stops and fricatives devoicing. Phonology test from the infantile language test (ABFW) was used to calculate productivity of phonological processes, the number of different types of phonological processes and the indexes PDI, PCC-R, IRS, IRO and IRD. Speech inconsistency test was applied to calculate the speech inconsistency index. Data were statistically analyzed. RESULTS: The study demonstrated that children with speech sound disorder and the presence of fricative and/or stops devoicing were more severe and presented higher values of the speech inconsistency index, PDI, IRS, IRO and IRD. The articulatory error most observed for both groups was the substitution while distortion occurred more in the group of children without the phonological process of devoicing. CONCLUSION: The severity indexes used were efficient to differentiate children with from children without the presence of the phonological processes of devoicing. There is evidence that children who have the phonological process of devoicing have difficulty with the phonological representation of the sound.
