          Abstract

          Mediante la prueba computarizada Memonum se evaluaron los efectos de dos intervalos de exposición de dígitos (1 y 8 segundos), y la presentación de un distractor sobre el desempeño de la memoria de trabajo en 80 mujeres mayores de 50 años. Se evidenció un efecto significativo del intervalo sobre las variables: número de aciertos, aciertos acumulados, y empleo de estrategias adicionales, demostrando un mejor desempeño mnemónico en participantes que presentaron la prueba en el intervalo de 8 segundos y sugiriendo que un tiempo amplio de exposición potencia la capacidad de almacenamiento de la memoria en adultos mayores. La presencia del distractor tuvo un efecto significativo sobre el número de aciertos acumulados, considerándose como un estimulo interferente capaz de afectar la memoria de trabajo en adultos mayores.

          Translated abstract

          By means of the Memonum computerized test the effects of two exhibition intervals of digits (1 and 8 seconds), and the presentation of a distracter were evaluated on the working memory performance in 80 women older than 50 years. Significant effect of the exhibition interval on the number of successes, total successes and use of additional strategies it was revealed, demonstrating better mnemonic performance of participants that presented the test in the interval of 8 seconds and suggesting that a wide time of contact with the information power the memory's storage capacity in older adults. The distracter presence had a significant effect on total successes variable, considered as interfere stimulus able to affect the working memory in older adults.

              The processing-speed theory of adult age differences in cognition.

              A theory is proposed to account for some of the age-related differences reported in measures of Type A or fluid cognition. The central hypothesis in the theory is that increased age in adulthood is associated with a decrease in the speed with which many processing operations can be executed and that this reduction in speed leads to impairments in cognitive functioning because of what are termed the limited time mechanism and the simultaneity mechanism. That is, cognitive performance is degraded when processing is slow because relevant operations cannot be successfully executed (limited time) and because the products of early processing may no longer be available when later processing is complete (simultaneity). Several types of evidence, such as the discovery of considerable shared age-related variance across various measures of speed and large attenuation of the age-related influences on cognitive measures after statistical control of measures of speed, are consistent with this theory.
