AbstractThe present paper gives an account regarding the findings from the design and implementation of an intervention model for psychology, conducted with children between 5 and 7 years old. The results were obtained by establishing measures of central tendency and variability for each of the groups; scores were compared pretest - posttest trials, using a univariate analysis of variance (ANCOVA) and nonparametric tests with U Mann-Whitney for variables without normal distribution. Within each group a comparison of intergroup differences of mean pretest, posttest with Wilcoxon rank sum. Subsequently, an analysis of covariance to compare mean Post-Test between the two groups adjusted for baseline levels, using this procedure, it was concluded that the intervention program designed improved the performance of participating children.
