Aging studies typically assess subjects after the age of maturity while developmental research focuses on changes before the age of maturity. There are few investigations of memory using the same assessment instrument in children, adults, and older adults. In the present study a computerized explicit memory task for visuospatial information was used to examine the effect of age on retention in subjects ranging in age from 5 to 89 years of age. It was hypothesized that visuospatial memory would decline with age, as has been demonstrated for verbal memory. Participants were administered a computerized version of the game of concentration or memory cards. A grid display of 24 cards (4 rows 6 columns) was presented on the computer screen. The subjects were instructed to turn over one card at a time to produce a picture and then match it by turning over the identical picture from the remaining cards. When a match was achieved the cards were taken out of play. Participants were instructed they would receive multiple trials and that the cards would remain in the sample place on all trials (five immediate trials and one 20 minute delayed trial). Subjects between 5 and 9 years of age performed significantly poorer than subjects 10-14 and 15-19 years of age. An age related memory decline was detected in subjects 40 years of age and older. Subjects in their 60s and 70s plus performed more poorly than all other age groups. In contrast to the poorer retention over a delay for verbal material demonstrated by the elderly, no delay related decline was detected for the visuospatial information in this task for any age group.
