Perceptual speed in adulthood: cross-sectional and longitudinal studies

Schaie, K. Warner·1989·Psychology and Aging

Abstract

Cross-sectional data on age differences in perceptual speed are presented from the Seattle Longitudinal Study for the age range 22-91 years (N = 1,620, first assessed in 1977; N = 628, first assessed in 1984). In addition, 838 subjects were followed over the 7-year interval. Markers of perceptual speed were the Identical Pictures and Finding A's tests from the ETS Kit of Factor-Referenced Tests. Significant age differences, age changes, and cohort differences were found at both observed variable and latent construct levels. Cross-lagged correlations examine the role of perceptual speed in predicting later performance on other abilities (Verbal Meaning, Inductive Reasoning, Spatial Orientation, Number, and Word Fluency). When perceptual speed is partialled out of scores for these abilities, aging effects are reduced markedly for all abilities, but least for Spatial Orientation and Inductive Reasoning.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Information processing speed accounts for a significant proportion of the variance in mental abilities such as fluid intelligence and working memory capacity.

    “This single factor in turn accounts for a significant proportion of the variance found in mental abilities such as fluid intelligence and working memory capacity (Salthouse, 1993; Schaie, 1989).”

  • Cognitive slowing cannot fully account for age-related cognitive decline.

    “However, it has been argued that cognitive slowing cannot fully account for age-related cognitive decline (Bugg et al., 2006; Salthouse, 1991; Schaie, 1989).”

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.
