Resumen

La orientación de la atención, por medio de una pista retroactiva endógena, para lugares de una escena memorizada, favorece positivamente el procesamiento de forma equivalente al favorecimiento asociado a la pista endógena en las tareas perceptivas. En la percepción pistas endógenas y exógenas tienen dinámicas temporales diferentes. Hemos investigamos la eficacia y la dinámica temporal de la recuperación de la información almacenada en la memoria de trabajo utilizando pistas retroactivas endógenas y exógenas, presentadas a diferentes intervalos antes del estímulo test. Nuestros resultados muestran que las pistas retroactivas endógenas y exógenas proporcionan un beneficio equivalente en exactitude (d’) y tiempo de respuesta, y que este beneficio aumenta con la asincronía entre pista y estímulo test. El rendimiento parece estar vinculado tanto a la validez de la pista, como al intervalo de estímulo, pero no a los diferentes tipos de pista, al menos en los intervalos investigados.
