Abstract
The standardization sample from the WMS–III (N
= 1250), which varied in age from 16 to 89, was used to determine
whether encoding, retrieval, or storage of verbal and spatial
information was most affected by normal aging. Immediate and
delayed recall and recognition of Logical Memory and Visual
Reproduction were examined. Immediate verbal and spatial recall
significantly deteriorated with increasing age, and the
age-associated deterioration in delayed recall and recognition
was largely explained by poorer immediate memory. These findings,
in concert with the smaller aging effects for percent retention
after a delay, suggest that the aging effect is due to
deterioration in encoding more than retrieval or storage of
new information. While Visual Reproduction deteriorated more
rapidly with age than Logical Memory, the pattern of performance
decrements as a function of age were comparable across both
tests. Decreases in performance were first seen in the fifth
decade with gradual deterioration until the eighth decade when
there was another precipitous drop. These results suggest that
functions that are more dependent on the frontal lobes are more
vulnerable to aging than those that are more dependent on the
temporal lobes. (JINS, 2003, 9, 89–96.)
