Resumen

La amplitud de Memoria de Trabajo (MT) se ha relacionado con el control de la atención en situaciones de interferencia. Sin embargo, existe discusión sobre la naturaleza unitaria o múltiple de la inhibición. En este estudio exploramos la relación entre la amplitud de MT y la inhibición en la memoria semántica y episódica. En el Experimento 1, participantes de alta y baja amplitud juzgaron la relación entre palabras mientras suprimían dibujos relacionados semánticamente (inhibición semántica). En el Experimento 2 exploramos la inhibición episódica mediante una tarea de interferencia proactiva. Los participantes de baja amplitud fueron susceptibles a la interferencia tanto semántica como episódica, mientras que las personas de alta amplitud resistieron a la interferencia en ambas tareas. Nuestros datos apoyan la relación entre la amplitud de MT y la susceptibilidad a la interferencia a través de mecanismos de supresión en memoria semántica y episódica.
