Trata-se de estudo correlacional, transversal, de natureza predominantemente quantitativa. Os instrumentos de coleta de dados s?o os subtestes do dom?nio ?Aten??o/ Fun??es Executivas? do NEPSY-II. Foram avaliadas 80 crian?as entre 5 e 8 anos de idade, de ambos os sexo, estudantes de escolas p?blicas e particulares da cidade de Natal - RN. A amostra foi segmentada em intervalos de seis meses para posterior an?lise das estrat?gias e tipos de erros. Foram realizadas an?lises de vari?ncia (multivariada e univariada), testes post hoc de Tukey e Games-Howell para verificar o efeito da idade sobre o desempenho nos testes. Correla??es posteriores indicaram a for?a e a dire??o do relacionamento entre as vari?veis. Identificaram-se dois picos de desenvolvimento no intervalo de seis meses adotado para as habilidades de aten??o seletiva e controle inibit?rio. Os resultados indicam que n?o h? influencia significativa do sexo e tipo de escola sobre o desempenho da amostra. O desempenho dos pr?-escolares (5 e 6 anos) foi inferior aos demais subgrupos na maioria dos testes. Destaca-se o papel do discurso de autoregula??o entre os pr?-escolares durante as atividades de maior demanda executiva e o recurso da abstra??o como estrat?gia de resolu??o entre os mais velhos. Identificaram-se trajet?rias de desenvolvimento semelhantes entre as habilidades de aten??o seletiva e controle inibit?rio. De maneira geral, h? decr?scimo no n?mero de erros e aumento de acertos com a progress?o da idade. Pesquisas longitudinais futuras podem ampliar a faixa et?ria abarcada neste estudo, investigando o curso desenvolvimental das habilidades executivas. / This study aimed to establish the developmental profile of executives components in typical child development. This is a correlational cross-sectional study of predominantly quantitative. The instruments for data collection are the subtests included in the NEPSY-II Attention and Executive Functioning domain. Eighty children between 5 and 8 years of age, of both genders, students from public and private schools in the city of Natal were evaluated. The sample was divided into six-month intervals for subsequent analysis of strategies and types of errors. Analysis of variance (univariate and multivariate) and Tukey and Games-Howell post hoc tests were conducted to verify the effect of age on test performance. Subsequent correlations indicate the strength and direction of the relationship between variables. Were identified two peaks of development in the six-month interval adopted for the skills of selective attention and inhibitory control. The results indicate that there?s no significant influence of sex and type of school on the performance of the sample. The performance of preschool children (5 and 6 years) was lower than the other subgroups in most tests. Highlights the role of autoregulation discourse among preschool children during activities of greater executive demand and the abstraction resource as a resolution strategy between the older. Were identified similar development trajectories among selective attention abilities and inhibitory control. In general, there is a decrease in the number of mistakes and increase of success with the age progression. Future longitudinal research can extend the age range encompassed in this study, investigating the developmental course of executive abilities.
