RESUMEN
We designed and evaluated the efficacy of a computer-based cognitive training program (Executive Function Enhancement Program [EFEP]) to stimulate executive functions through enhancing planning in normally-developing children. A total of 111 Colombian children participated in the study. Fifty-nine (53%) of the children were assigned to the experimental condition (application of the EFEP program) with two levels of planning performance, and fifty-two (47%) to the waiting list control condition with the same two levels of planning. The training program was applied three times a week over six weeks, with post-intervention assessment two weeks after the end of training. A follow-up assessment was carried out three months later. Results showed that the intervention program was particularly effective in the children with lower pre-intervention performance in planning, demonstrating that the program is an efficient therapeutic instrument for enhancing the executive function of planning in children between 5 and 7 years old.
