Specifically analyze possible effects on DHH children’s phonological processing skills.
Methods: The study included 48 children who participated in a
computer-assisted intervention study, which focuses on phoneme grapheme correspondence. Children were 5, 6, and 7 years of age. There were 32 DHH children find more using cochlear implants (CI) or hearing aids (HA), or both in combination, and 16 children with NH. The study had a quasi-experimental design with three test occasions separated in time by four weeks; baseline 1 and 2 pre intervention, and 3 post intervention. Children performed tasks measuring lexical access, phonological processing, and letter knowledge. All children were asked to practice ten minutes per day at home supported by their parents.
Results: NH children outperformed DHH children on the majority of tasks. All children improved their accuracy in phoneme grapheme correspondence and output phonology as a function of the computer-assisted intervention. For the whole group of children, and specifically for children with CI, a lower initial phonological composite score was associated with a larger phonological change between baseline 2 and post intervention. Finally, 18 DHH children, whereof 11 children with CI, learn more showed specific intervention effects on their phonological processing skills, and strong effect sizes
for their improved accuracy of phoneme grapheme correspondence.
Conclusion: For some DHH children phonological processing skills are boosted relatively
more by phoneme grapheme correspondence training. This reflects the reciprocal relationship between phonological change and exposure to and manipulations of letters. (C)2013 Elsevier Ireland Ltd. All rights reserved.”
“Aerial parts essential oil of Nepeta betonicifolia and N. saccharata were obtained by hydrodistillation and selleck analysed by GC-FID and GC-MS. Thirty-three and eighteen components represented 97.9% and 98.2% of the total oils identified, respectively. Main compounds of the oil of N. betonicifolia were 4a alpha,7 beta,7a alpha-nepetalactone (42.0%), germacrene D (6.0%), triplal (5.2%), 1-nor-bourbonanone (4.0%) and 1,8-cineole (3.2%). The principal constituents of the essential oil of N. saccharata were found to be 4a beta,7 alpha,7a beta-nepetalactone (66.9%), germacrene D (12.9%), sabinene (6.5%) and trans-caryophyllene (3.3%). The radical scavenging capacity (RSC) of methanol extracts and chloroform, butanol and water subfractions of aerial parts of N. betonicifolia and N. saccharata were evaluated by using DPPH, FRAP and ABTS assays. TPC of each extract was measured using Folin-Ciocalteau. The antioxidant activity of the butanolic subfractions of both plants was higher than other extracts examined.”
