Pesquisa do Estado do Rio Grande do Sul (FAPERGS) / There is relative consensus that low level and quality of education are limiting factors of a country?s growth. Statistics show that many students have difficulties in learning or do not display the necessary abilities to succeed academically. Trying to reduce such difficulties, neuropsychology has developed remediation and rehabilitation interventions. There is, however, a need to invest in intervention programs that promote cognitive health and stimulate neurocognitive skills among children. These programs may potentiate cognitive processes and lead to short and long term benefits. Evidence shows that the executive functions (EF) have a crucial role in education, and are relevant in learning and in autoregulatory behavior. Given this context, the objective of this thesis was to develop and verify the effectiveness of an early and preventive neuropsychological intervention program with the intent of stimulating the EF among Elementary School students. The program was called Program of Neuropsychological Stimulation of Cognition in Students: emphasis on Executive Functions, or PENcE (an acronym from its original name in Portuguese, Programa de Estimula??o Neuropsicol?gica da Cogni??o em Escolares: ?nfase nas Fun??es Executivas). The First Study performed a systematic review of empirical studies about neuropsychological interventions of EF among children with typical development, looking for an overview that could guide the construction of the PENcE. Nineteen studies were found through the PRISMA method: most of them provided evidences that the children who participated in the intervention programs improved their executive functions. For the most part, they used computerized cognitive training to stimulate working memory. Other studies proposed a curricular approach to potentiate autoregulation. It was possible to observe that the studies are very heterogenic in terms of approach, methods, and closing measurement tools. Computerized trainings seem improve trained cognitive skills, but are limited in terms of transferring gains. Curricular programs seem more generalizable, with effects on transferring gains and functionality. The objective of the Second Study was to present the process of construction and content validity evidences for the PENcE. There were four steps involved in reaching that goal: internal stage of program organization; program construction; analysis by expert judges; and data integration and program finalization. All stages were important and contributed to improve the program. Furthermore, the assessment of the program (global and of each module) presented a level of agreement among judges equal to one, allowing for the achievement of content validity evidences. Finally, the Third Study investigated the effectiveness of the PENcE among children attending 3rd and 4th grades of Elementary School. It also analyzed the effects of transferring to other skills (executive, cognitive, academic, behavioral) beyond the main executive closings. From an initial sample of 160 children, 113 participated in the study. They were divided into two groups: experimental group (EG) (n=64) and control group (CG) (n=49). There were no differences between the groups before the intervention. After the study, the groups were compared, and the EG presented significant gains in inhibitory control, working memory, and abstract planning. There were transferring effects to other cognitive abilities (such as attention and fluid thinking), academic abilities (math and written skills), and changes in behavior (relationship and behavioral problems), and the overcame the CG. As a group, the findings from the three studies offer an early and preventive intervention program that has theoretical basis, has followed a rigorous construction process, and possesses content validity and effectiveness analysis. For future studies, it is suggested to extend and adapt the program to other age groups and to children who already present executive deficits, including learning difficulties and ADHD. Moreover, with the goal of contributing to public policies, it is recommended that the PENcE be implemented in public schools in developing countries, helping to bridge the gap between neuropsychology and education in a practical way. / Atualmente, h? relativo consenso de que o baixo n?vel educacional e a reduzida qualidade do processo de escolariza??o s?o fatores limitadores de crescimento de um pa?s. Al?m disso, as estimativas mostram que um elevado n?mero de alunos apresenta dificuldades de aprendizagem ou n?o apresenta habilidades necess?rias para ter sucesso acad?mico. Na tentativa de contribuir com a diminui??o de tais dificuldades, a neuropsicologia desenvolveu predominantemente interven??es de remedia??o e de reabilita??o. Destaca-se, contudo, a necessidade de se investir em programas de interven??es de promo??o ? sa?de cognitiva e de estimula??o de habilidades neurocognitivas em crian?as, uma vez que tais programas podem potencializar os processos cognitivos e levar a benef?cios de curto a longo prazo. Com o avan?o da neuropsicologia, h? evid?ncias de que as fun??es executivas (FE) t?m um papel crucial na educa??o e s?o relevantes para aprendizagem e comportamento autorregulat?rio. Frente a esse contexto, essa tese teve como objetivo desenvolver e verificar a efetividade de um programa de interven??o neuropsicol?gica precoce-preventiva em busca da estimula??o das FE em escolares no Ensino Fundamental I. Tal programa foi denominado Programa de Estimula??o Neuropsicol?gica da Cogni??o em Escolares: ?nfase nas fun??es executivas (PENcE). No primeiro estudo, a partir de uma revis?o sistem?tica, buscou-se caracterizar os estudos emp?ricos sobre interven??es neuropsicol?gicas de FE em crian?as com desenvolvimento t?pico, em busca de um panorama que norteasse a constru??o do PENcE. Seguindo o m?todo PRISMA, foram encontrados 19 estudos e a maioria forneceu evid?ncias que as crian?as que participaram dos programas de interven??o melhoraram suas habilidades executivas. A maioria utilizou o treino cognitivo computadorizado, envolvendo a estimula??o da mem?ria de trabalho. Outros propuseram uma abordagem curricular com intuito de potencializar a autorregula??o. Foi poss?vel verificar que os estudos s?o bastante heterog?neos em rela??o a tipos de abordagem, m?todos e instrumentos de medida de desfecho. Contudo, os treinos computadorizados parecem levar a uma melhora na habilidade cognitiva treinada, por?m, s?o limitados em termos de transfer?ncia de ganhos. Os programas de abordagem curricular, por sua vez, parecem mais generaliz?veis, com efeito de transfer?ncia e ganho na funcionalidade. No Estudo 2, objetivou-se apresentar o processo de constru??o e evid?ncias de validade de conte?do do PENcE. Para isso, quatro etapas foram realizadas: fase interna de organiza??o do programa; constru??o do programa; an?lise de ju?zes especialistas; integra??o dos dados e finaliza??o do programa. Todas as etapas foram essenciais e contribu?ram para aprimorar o programa. Al?m disso, evidenciou-se que a avalia??o global do programa e de cada um dos m?dulos apresentou um n?vel de concord?ncia de 1,0 entre os ju?zes, permitindo obter evid?ncias de validade de conte?do. Por fim, no Estudo 3 buscou-se investigar a efetividade do PENcE em crian?as do 3? ou 4? ano do Ensino Fundamental, bem como, analisar o efeito de transfer?ncia para outras habilidades executivas e cognitivas, habilidades acad?micas e comportamento, para al?m dos desfechos executivos principais. De uma amostra inicial de 160 crian?as, 113 participaram do estudo e foram subdivididas em dois grupos: grupo experimental (GE) (n=64) e grupo controle (GC) (n=49). Os grupos n?o se diferenciaram em nenhuma medida na avalia??o pr?-interven??o. Na compara??o dos grupos, verificou-se o GE apresentou ganhos significativos de controle inibit?rio, mem?ria de trabalho, planejamento abstrato. Houve efeito de transfer?ncia para outras habilidades cognitivas (como aten??o e racioc?nio fluido), habilidades acad?micas (matem?tica e escrita) e mudan?a no comportamento (relacionamento e problemas de conduta), sendo que o GE superou o GC. Em conjunto, os achados dos tr?s estudos contribuem disponibilizando um programa de interven??o precoce-preventiva, que possui embasamento te?rico, que seguiu um rigoroso processo de constru??o e que denota de validade de conte?do e de an?lise de efetividade. Sugere-se, para os pr?ximos estudos, estender e adaptar o programa para outras faixas et?rias e para grupos de crian?as que j? apresentam d?ficits executivos, como com transtornos espec?ficos de aprendizagem e TDAH. Al?m disso, visando a contribuir com as pol?ticas p?blicas, recomenda-se que o PENcE possa ser implementado em escolas p?blicas nos pa?ses em desenvolvimento, rumo a uma interface cada vez mais pr?tica entre neuropsicologia e educa??o.
