RESUMO

En este estudio investigamos el efecto de la edad en dos tareas de memoria implícita, la prueba de compleción de raíces y la de generación de categorías, y comparamos la actuación de jóvenes y mayores en estas pruebas con la actuación en una prueba de memoria explícita (reconocimiento ‘antiguo-nuevo’). Nuestra predicción fue que los jóvenes actuarían mejor que los mayores en la prueba de reconocimiento, mientras que ambos grupos mostrarían efectos de priming similar en ambas pruebas de memoria implícita. Los resultados mostraron: (a) en los dos grupos de edad hubo priming en ambas tareas de memoria implícita; (b) los jóvenes mostraron más priming que los mayores en la tarea de compleción de raíces, mientras el priming fue similar en ambos grupos en la tarea de generación de categorías; y (c) los jóvenes actuaron mejor que los mayores en la prueba de memoria explícita. Estos resultados no solo mostraron disociación entre las tareas de memoria implícita y explícita, sino también entre dos tareas de memoria implícita (AU)


In this study, we investigated the effect of aging on two implicit memory tasks, word-stem completion and category generation, and on explicit recognition. We compared the performance of young and older adults on these implicit memory tasks with those of explicit recognition. We expected better performance of young than older adults in the explicit memory task and similar priming in both implicit memory tasks. The results showed that young adults performed better than older adults in the recognition task. Moreover, both age groups showed priming in the implicit memory tasks, although priming was greater in young adults compared to older adults in the word-stem completion memory task, whereas both age groups showed similar levels of priming in the category generation task. The present results showed dissociations as a function of age not only between the explicit and the implicit tasks but also between the implicit tasks (AU)
