The objective of this research was to analyze the effects ofan intervention program through neurofeedback, on the cognitiveperformance in children with inattention indicators. Aquasi-experimental pretest-posttest study was used under apositivist epistemology, with a comparative analysis for eachevaluated cognitive process. A sample of 29 cases was intentionallyselected from a group of children and young adolescentswith low performance indicators from a TherapeuticCenter from Cucuta-Colombia. The neurofeedback programwas developed in 20 sessions with the purpose of increaselow-beta waves (12-16 Hz) and inhibition theta waves (4-7Hz). A comparative statistically analysis with five months ofdifference was carried out using Wilcoxon test, finding significantdifferences between the pretest and the posttest inneuropsychological tests of auditory-visual attention, encodingmemory and planning. The results are discussed with empiricalbackgrounds that have shown positive effects in thistype of interventions.
