Over the last few decades, different interventions were shown to be effective in changing cognitive performance in preschoolers from poor homes undertaking tasks with executive demands. However, this evidence also showed that not all children included in the intervention groups equally increased their performance levels, which could be related to individual and contextual variability. The present study aimed to explore the impact of a computerized cognitive training intervention with lab-based tasks in preschoolers from Unsatisfied Basic Needs (UBN) homes under the consideration of their baseline performance. In the context of a randomized controlled trial design, different interventions were administered to children according to their baseline performance in a variety of cognitive tasks (i.e., executive attention, inhibitory control, working memory, and planning demands). The results showed different patterns of impact on performance depending on the experimental group, supporting the importance of considering individual and contextual differences in the design of interventions aimed at optimizing executive functions in poverty-impacted sample populations in early stages of development.

The use of human neuroimaging technology provides knowledge about several emotional and cognitive processes at the neural level of organization. In particular, electroencephalographic (EEG) techniques allow researchers to explore high-temporal resolution of the neural activity that underlie the dynamics of cognitive processes. Although EEG research has been mostly applied in laboratory settings, recently a low-cost, portable EEG apparatus was released, which allows exploration of different emotional and cognitive processes during every-day activities. We compared a wide range of EEG measures using both a low-cost portable and a high-quality laboratory system. EEG recordings were done with both systems while participants performed an active task (Go/NoGo) and during their resting-state. Results showed similar waveforms in terms of morphology and amplitude of the ERPs, and comparable effects between conditions of the applied Go/NoGo paradigm. In addition, the contribution of each frequency to the entire EEG was not significantly different during resting-state, and fluctuations in amplitude of oscillations showed long-range temporal correlations. These results showed that low-cost, portable EEG technology can provide an alternative of enough quality for measuring brain activity outside a laboratory setting, which could contribute to the study of different populations in more ecological contexts.

Durante el nivel inicial, los infantes suelen recibir respuestas emocionales y conductuales de manera impulsiva, dado que carecen de la aptitud de abstención de conductas que no son afectadas a la ocasión. En este punto, las Habilidades Sociales (HHSS) y las Funciones Ejecutivas (FE) serán facilitadoras de la interacción asertiva con otros, favoreciendo el control conductual y evitando los Problemas de Conducta (PC). El objetivo de este estudio fue analizar la correlación entre las FE, la percepción parental en relación con las emociones, y la percepción de los docentes respecto de las HHSS y la conducta en niños del nivel inicial de educación; a tal fin se realizó un estudio cuantitativo, transversal, descriptivo-correlacional, en base a un diseño no experimental. La muestra estuvo integrada por 36 niños / as de nivel inicial, a quienes se les administró una batería neuropsicológica, además se incluyeron dos cuestionarios, uno para padres y otro para docentes. Se encontró correlación entre HHSS y PC; entre Planeación y Emociones; y entre Atención y Concentración y Memoria de Trabajo. Se concluye que los niños de nivel inicial tienen una conducta socialmente habilitada, y manejan sus emociones sin dificultad indistintamente del sexo, según la perspectiva parental y docente.

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.

Contemporary evidence shows that different intervention approaches can be effective in improving executive cognitive performance in preschoolers from poor homes. However, several aspects about the role of individual and contextual differences in intervention effects remain to be elucidated. The present study aimed to explore the impact of a computerized executive cognitive intervention with lab-based tasks in preschoolers from Unsatisfied Basic Needs (UBN) homes. In the context of a randomized controlled design, different activities were administered to children according to their baseline performance in a variety of cognitive tasks tapping inhibitory control, working memory, and planning demands (i.e., high- and low-performance intervention and control groups). Results suggested that the impact of the intervention was shown preferentially by high-performers in Tower of London and K-Bit tasks, who increased their performances in the posttest assessment. This finding supports the importance of considering individual and contextual differences in the design of interventions aimed at changing the cognitive performance of children from poor homes.
