Neuropsychological aspects of 10-year-old children

Abstract

Objective: To characterize neuropsychological aspects of 10-yearold children. Method: Out of 30 children, 26 cognitively normal 10-year-old public school students answered tests extracted from Luria-Nebraska Neuropsychological Battery: Children's Revision. The study was transversal. Descriptive and inferential statistical analysis were carried out. Results: Most of the 10-year-old children retold a story (69.2%), understood it making correct inference (84.6%) and reproduced it adequately in writing (76.9%) -14.9% was the average number of incorrectly written words and 0.179 was the errors per written word coefficient. Besides, 53.8% showed logical thought process and 73.1% had a correct notion of "x more than…". They got five out of eight in the visuo-spatial test, an intermediary result. These results show that the tertiary areas of units II and III are developed in most 10-year-old children. The most frequent types of written mistakes were: oral influence (26.3%), multiple representation (22.5%) and omission (18.4%). As to coding principles, the mostly uncomplied with rule was vowel nasalization at end of syllable (23,53%). Conclusions: Ten-year-old children in the studied population understood and reproduced a story orally and in writing with a low coefficient error/word. The majority completed the visuospatial tests and presented logical thought process. When "x more than…" notion is absent it may be an indicator that all is not well in the reading/writing process. estatística descritiva e inferencial. Resultados: A maioria das crianças recontou a história (69,2%), fez sua inferência mostrando tê-la compreendido (84,6%) e a reproduziu adequadamente por escrito (76,9%). Em média, apresentaram 14,9% de palavras escritas incorretamente e coeficiente de 0,179 erros/palavra escrita. Além disso, 53,8% tiveram raciocínio lógico e 73,1% tinham uma noção de "a mais". Responderam cinco de oito no teste visuo-espacial, sendo este um resultado intermediário. Esse desempenho atesta que, aos dez anos, as áreas terciárias da unidade II e III, estão desenvolvidas na maioria das crianças. Tipos de erros grafêmicos mais frequentes: oralidade (26,3%), representação múltipla (22,5%) e omissão (18,4%). A regra referente à nasalização da vogal em final de sílaba não final de vocábulo foi a mais desrespeitada (23,53%). Conclusão: Estudantes de 10 anos da população estudada compreenderam e reproduziram oralmente e por escrito uma história com baixo coeficiente de erros/palavra escrita. A maioria respondeu à prova visuo-espacial e apresentou raciocínio lógico. A ausência de noção de "a mais" pode ser um preditor de inadequação de leitura/escrita. Keywords

Evidences of validity and reliability of the Luria-Nebraska Test for Children

“…Along the development from preschool age to adolescence there is acquisition and refinement of cognitive functions. This result is supported by the maturation of the nervous system (especially the myelination and optimization of neural networks by synaptic pruning) and environmental stimulation that usually puts the child before many cognitive challenges, mainly in school activities (Osborn & Pereira, 2012).…”

There is no pulp necrosis or calcific metamorphosis of pulp induced by orthodontic treatment: biological basis

“…The orthodontic forces are very light in any situation, because the goal is to induce these phenomena of cellular stress and periodontal ligament inflammation in the periodontal ligament, which represents a membranous structure of only 0.25mm - which corresponds to the thickness of a paper leaf - formed by specialized fibrous connective tissue. 1 , 2 …”

“…This represents a physiological mechanism of the periodontal ligament to cushion the heavy masticatory forces. 1 , 2 Considering that this applies to the occlusal loads, which are very intense and incomparably extreme or heavy, by deduction it may be inferred that they apply even more to orthodontic forces, which are extremely light or moderate.…”
