Resumen

El Retén Episódico (RE) está tomando un creciente papel central en las explicaciones sobre el funcionamiento de la memoria operativa. De hecho, los últimos estudios de Baddeley y sus colaboradores sitúan al RE en el corazón del sistema de memoria. Recientemente la discusión también atañe a si este componente de la memoria operativa presenta una naturaleza independiente respecto a los recursos del ejecutivo central. Algunos estudios muestran como en tareas automatizadas, la construcción y mantenimiento de elementos almacenados en el RE no requieren de recursos desde el ejecutivo central.

El presente trabajo pretende analizar esta cuestión para lo que se toman diferentes variables y se ha diseñado un nuevo test para medir el EB. En este test de doble tarea, la tarea secundaria consiste en la lectura de textos sencillos que contienen palabras ocultas. Los resultados muestran como a pesar del aumento del procesamiento debido al incremento de la longitud de los textos, no se produce un aumento en la carga demandada por el ejecutivo central, ni en la creación de los agrupamientos de información ni en su mantenimiento. Es por ello, que pensamos que el RE bajo ciertas circunstancias es independiente del ejecutivo central.
