The Lacunae of Loss? Aging and the Differentiation of Cognitive Abilities

Rabbitt, Patrick, Anderson, Mike·2006·Lifespan CognitionMechanisms of Change

Abstract

This chapter examines the effect of aging on cognitive abilities and asks whether all cognitive abilities show evidence of decline or whether some abilities are relatively spared. Declines in specific abilities would be lacunae of loss sparing the archipelagos of surviving abilities. This chapter looks at evidence from the perspective of maintenance or loss of consistency of relationships between mental abilities as age advances. Analysis of cross-sectional data from a large elderly sample showed age impaired performance on all tests that individuals were given, with the exception of some vocabulary tests. However, the amounts of total variance in test performance associated with differences in age between forty-nine and ninety-two years were very modest—not exceeding 22%. Further analysis of the data set showed that levels of correlations between scores on intelligence tests and other tests of fluid intelligence, between intelligence tests and other cognitive tests, and between other cognitive tests are consistently higher in a sample aged from seventy to ninety-two years than in a sample aged from forty-nine to sixty-nine years.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
