A Study of Memory in Aged People
Memory performances were studied in a group of 22 old (65–74 years) and 29 very old (75–91 years) women, and compaired with performances of a group of 31 middle-aged (35–49 years) women, matched for socio-economic and cultural level. The intellectual level did not differ significantly as estimated by the Terman Vocabulary test, but in Raven’s Coloured Matrices there was a considerable decline with age. Digit span forwards and still more backwards was reduced with age.
To study memory performances, a test comprising three subtests, 30 figures, 30 word pairs and 30 personal data were used. Remembering was studied both immediately after presentation of the material (immediate memory score) and three hours later (delayed memory score), the difference between the two being forgetting scores. A considerable decline of immediate and delayed memory scores with age was found, but forgetting measures did not increase. The regression lines between immediate and delayed scores were also quite similar. The findings indicate a pronounced decline of registration with age but do not show any decline of retention, such a decline of course not being disproved.
