The objective of this research was to analyze the effects of an intervention program through neurofeedback, on the cognitive performance in children with inattention indicators. A quasi-experimental pretest-posttest study was used under a positivist epistemology, with a comparative analysis for each evaluated cognitive process. A sample of 29 cases was intentionally selected from a group of children and young adolescents with low performance indicators from a Therapeutic Center from Cucuta-Colombia. The neurofeedback program was developed in 20 sessions with the purpose of increase low-beta waves (12-16 Hz) and inhibition theta waves (4-7 Hz). A comparative statistically analysis with five months of difference was carried out using Wilcoxon test, finding significant differences between the pretest and the posttest in neuropsychological tests of auditory-visual attention, encoding memory and planning. The results are discussed with empirical backgrounds that have shown positive effects in this type of interventions.
