Memoria del contexto informacional en el envejecimiento fisiológico | Revista Española de Geriatría y Gerontología

Información del artículo

Objetivos

Estudiar los efectos del envejecimiento normal sobre la memoria del contexto de la información (dónde, cuándo y cómo una información se aprende) y sus posibles relaciones con un disfuncionamiento frontal asociado a la edad.

Método

Se evalúan un grupo de sujetos normales, formado por 19 jóvenes adultos y otro por 18 ancianos. Ambos grupos tenían que aprender nueva información real y dos horas más tarde, tenían que recodar la información, así como el contexto en el que la han aprendido. También contestaban a una batería de tests que valoran el funcionamiento frontal: Trail Making, Stroop, Fluencia Alternada y test de Wisconsin.

Resultados

El grupo de ancianos cometía más errores contextuales (72%) que el grupo de jóvenes (16%). El grupo de ancianos mostraba un mayor número de errores contextuales de tipo intraexperimental (39%). Este grupo presentaba peores resultados en los tests frontales que el grupo de los jóvenes, pero esos resultados no estaban relacionados con los de la memoria contextual.

Conclusiones

El grupo de ancianos presenta un olvido del contexto informacional. Pero nuestros resultados no han podido confirmar que el funcionamiento frontal de nuestro grupo de ancianos estuviese relacionado con la memoria contextual.

Objectives

Study the effects of normal aging on the source memory of the information (where, when and how the information is learned) and its possible relationships with a frontal dysfunctioning associated with age.

Method

A group of normal subjects, consisting in 19 young adults and 18 elderly subjects, is evaluated. Both groups had to learn new real information and had to remember the context in which it had been learned in addition to the information two hours later. They also answered a series of tests that assess the frontal functioning: Trail making, Stroop, Altered fluency and Wisconsin test.

Results

The elderly group committed more contextual errors (72%) than the young group (16%). The elderly group showed a greater number of intraexperimental contextual errors (39%). This group presented worse results in the frontal tests than the young group, but these results were not related with those of the source memory.

Conclusions

The elderly group presents a forgetfulness of the informational source. However, our studies could not confirm that the frontal functioning of our elderly group was related with the memory source.
