One hundred students (64 girls) from Public Schools, with ages raging between 8:0 and 11:11 years, were selected. Twenty students (12 girls) participated in the applicability study, resulting in the study version of the Scales. These scales were later applied to the remaining 80 students (52 girls). The obtained responses were assessed and computed for score assignment: item scores, competence field score (CFS) and raw scale score (RSS). Data were submitted to statistical analysis: the Cronbach's alpha coefficient was calculated and correlations between items (Pearson's correlation coefficient) were verified. A significance level of 0.05 was used.Results: a = 0.866 and a = 0.461 were obtained for the Reading and Writing Scales, respectively. Correlations between the items were observed, ranging from weak to strong, and confirmed the alpha values.Conclusion: The Reading Scale was proven reliable, achieving acceptable levels for diagnostic instruments; the Writing Scale did not present an acceptable reliability level to measure the performance of the tested children.","PeriodicalId":74581,"journal":{"name":"Pro-fono : revista de atualizacao cientifica","volume":"22 4","pages":"509-14"},"PeriodicalIF":0.0,"publicationDate":"2010-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1590/s0104-56872010000400025","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29629667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Participants were 9 children divided in three groups: children in the acquisition process of the phonological contrast (G1); children with phonological disorder (G2); and children with typical productions (G3). The speech productions were analyzed and edited using software Praat. The acoustic parameters adopted were: burst spectral characteristics; CV transition and durational characteristics. Duration parameters were analyzed by Friedman ANOVA while the other parameters were analyzed using two-way ANOVA and Hierarchical Linear Modeling. The adopted statistical significance level was of 0.05.Results: Acoustic analysis indicated the presence of covert contrast in the productions of children in G1 and G2 (80% and 57.14% of substitutions respectively). In addition, acoustic analysis revealed differences in how well the children differentiated the two occlusives and which acoustic parameters were used to differentiate them.Conclusion: A lot of the substitutions presented in the speech of children in typical and deviant acquisition process are in fact covert contrasts.

Fifteen stories were used in the study. Each story was illustrated by four figures. The sequences of figures were created and classified as mechanical, behavioral and intentional according to the relationships presented among the characters. Data were transcribed and analyzed regarding the type of discourse (descriptive, causal and intentional) and the type of organization of the figures.Results: No differences between age groups were observed for temporal ordering. For all age groups, the most frequently presented discourse type was the causal one. Statistically significant differences were observed among age groups for the causal and intentional discourse type. Inasmuch as the age increased, school-age children with TLD reduced the use of the descriptive discourse and increased the use of the intentional one.Conclusion: The ability of temporal ordering is already developed in children with TLD at seven-years of age.

Amplitude was higher in the control group. There was no significant difference between the groups for pure tone thresholds from 0.25 to 20 KHz.Conclusion: The DPOAE were more effective, in comparison to the pure tone audiometry, to detect auditory differences between the groups.

Tests were conducted in three sessions: prior to the adaptation of the hearing aids, fourteen days and three months later.The Portuguese Sentences Lists test in free field was used for testing, and the SRTQ and SRTN were obtained (with noise level settled at 65 dB A). Results were expressed through the signal/noise ratios.Results: The mean values for the SRTQ in the 1st, 2nd and 3rd sessions were 54.43, 51.71 and 52.22 dB A respectively,.
