- 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.
- Tongue contour for /s/ and /?/ in children with speech sound disorder(2014) WERTZNER, Haydée Fiszbein; FRANCISCO, Danira Tavares; PAGAN-NEVES, Luciana de OliveiraPURPOSE: To describe the tongue shape for /s/ and /∫/ sounds in three different groups of children with and without speech sound disorder. METHODS: The six participants were divided into three groups: Group 1 - two typically developing children, Group 2 - two children with speech sound disorder presenting any other phonological processes but not the ones involving the production of the /∫/ and Group 3 - two children with speech sound disorder presenting any phonological processes associated to the presence of the phonological process of palatal fronting (these two children produced /∫/ as /s/) aged between 5 and 8 years old, all speakers of Brazilian Portuguese. The data were the words /'∫avi/ (key) and /'sapu/ (frog). Tongue contour was individually traced for the five productions of each target word. RESULTS: The analysis of the tongue contour pointed to evidences that both /s/ and /∫/ were produced using distinct tongue contours for G1 and G2. The production of these two groups was more stable than G3. The tongue contour for /s/ and /∫/ from the children in G3 was similar, indicating that their production was undifferentiated. CONCLUSION: The use of the ultrasound applied to the speech analysis was effective to confirm the perceptual analysis of the sound made by the speech-language pathologist.
- Ocorrência de erros fonológicos de acordo com a gravidade em crianças com transtorno fonológico(2014) WERTZNER, Haydée Fiszbein; SANTOS, Perla Isabel dos; PAGAN-NEVES, Luciana de OliveiraPurpose to describe and quantify speech errors in children with speech sound disorder according to severity calculated by the indexes percentage of consonants correct revised and process density index and also to determine whether children with different degrees of severity differ in the predominant error observed during speech production. Methods speech samples of 21 children aged between 5;2 and 7;11 years-old with speech sound disorder were analyzed. Absolute indexes of substitution, omission and distortion, percentage of consonants correct revised and process density index were calculated based on two phonology tasks (picture naming and imitation of words). Results there were differences in the predominant type of error in speech indicating that substitution was the most occurring type of error. Substitution was the most frequent type of error for the most severe children while for the less severe ones the study did not indicate a prevalent type of error. The analysis of the total sample the correlation analysis indicated that the higher the occurrence of substitution less the number of distortion. Conclusion in general terms substitution was the most frequent type of error. Equivalence of the type of errors was observed for the less sever children while substitution was the most frequent type of error for the more sever group of children. Absolute indexes were effective and efficient to indicate the most frequent type of error according to the severity of the disorder.
- Auditory and Visual Sustained Attention in Children with Speech Sound Disorder(2014) MURPHY, Cristina F. B.; PAGAN-NEVES, Luciana O.; WERTZNER, Haydee F.; SCHOCHAT, ElianeAlthough research has demonstrated that children with specific language impairment (SLI) and reading disorder (RD) exhibit sustained attention deficits, no study has investigated sustained attention in children with speech sound disorder (SSD). Given the overlap of symptoms, such as phonological memory deficits, between these different language disorders (i.e., SLI, SSD and RD) and the relationships between working memory, attention and language processing, it is worthwhile to investigate whether deficits in sustained attention also occur in children with SSD. A total of 55 children (18 diagnosed with SSD (8.11 +/- 1.231) and 37 typically developing children (8.76 +/- 1.461)) were invited to participate in this study. Auditory and visual sustained-attention tasks were applied. Children with SSD performed worse on these tasks; they committed a greater number of auditory false alarms and exhibited a significant decline in performance over the course of the auditory detection task. The extent to which performance is related to auditory perceptual difficulties and probable working memory deficits is discussed. Further studies are needed to better understand the specific nature of these deficits and their clinical implications.
