ABSTRACT
Resumen El ámbito educativo, indudablemente, puede beneficiarse de los aportes de las neurociencias, enfoque desde el cual, en este estudio, se plantearon los objetivos de explorar la relación existente entre la capacidad intelectual (CI), las funciones ejecutivas (FE) y el rendimiento académico (RA) en adolescentes; analizar si la CI y las FE constituyen variables predictoras del RA, e indagar el funcionamiento ejecutivo de la muestra según la CI fuera baja o alta. Para ello, se realizó un estudio no experimental, transversal, descriptivo-correlacional, en el que participaron 36 sujetos de 13-14 años. Los instrumentos de evaluación utilizados fueron WISC-IV, BANFE-2 y el registro de calificaciones provisto por la institución educativa. Los datos obtenidos fueron sometidos a análisis descriptivos, de correlación y de regresión. Los resultados arrojaron correlación positiva significativa entre las variables CI y FE, y entre la prueba WISC-IV y RA, determinándose el CI como variable predictiva del RA, mientras que en relación con las FE evaluadas con BANFE-2 solo se encontró asociación estadísticamente significativa con las subpruebas correspondientes al área prefrontal anterior. Además se observaron diferencias significativas entre los grupos de alta y baja CI en las FE de planificación, memoria de trabajo (MT) y fluidez verbal, en favor del grupo de alto desempeño intelectual. La conclusión se centra en la importancia de involucrar los hallazgos sobre los diferentes procesos cognitivos en el diseño de las estrategias pedagógicas para favorecer al máximo el RA del estudiante. Finalmente, las limitaciones versaron en relación con el tamaño muestral, y se proponen futuras líneas de estudio que posibiliten generalizar los resultados.
Abstract The study of the relationship between executive functions, intellectual abilities, and academic achievement plays an important role in the field of cognitive neuroscience, particularly for their implications in the educational field. Intelligence has been linked to executive functions. In fact, core aspects of intelligence, such as reasoning, problem-solving and planning, are often included in the wide range of frontal lobe functions and over laps with the so-called higher-level executive functions. In addition, executive functioning abilities are associated with skills put in play when participating in learning activities at school. In this sense, different studies have demonstrated that a lower performance on executive function measures typically is associated with a lower performance across different academic areas. The aim of this work was focused on the relationship between intelligence and executive functions, and their ability to predict academic achievement. In the present study, a non-experimental, transversal and descriptive-correlational design was implemented to explore the relationship between intellectual abilities, executive functions, and academic performance in a sample of 37 adolescents (17 girls) aged 13-14 years. The information was collected through the school reports of participants, and their performance on tests BANFE-2 (neuropsychological battery of the executive functions and frontal lobes) and WISC-IV (Wechsler intelligence scale for children 4th Ed.). Also, adolescents were classified into two groups (high- and low performers) based on their performance on the general intelligence score. Participants with IQ scores below the median were assigned to the low-performing group, while participants with IQ scores above the median were assigned to the high-performing group. The data obtained were subjected to descriptive, correlation and regression analyses. Results showed a pattern of positive and significant correlations between executive functions variables (BANFE-2) and intelligence scores (WISC-IV). The 69 % of significant correlations indicated a moderate - strong degree of association (i. e., 49
