Age and flexible thinking: An experimental demonstration of the beneficial effects of increased cognitively stimulating activity on fluid intelligence in healthy older adults

Tranter, Lesley J., Koutstaal, Wilma·2008·Aging Neuropsychology and Cognition

Abstract

The disuse hypothesis of cognitive aging attributes decrements in fluid intelligence in older adults to reduced cognitively stimulating activity. This study experimentally tested the hypothesis that a period of increased mentally stimulating activities thus would enhance older adults' fluid intelligence performance. Participants (N=44, mean age 67.82) were administered pre- and post-test measures, including the fluid intelligence measure, Cattell's Culture Fair (CCF) test. Experimental participants engaged in diverse, novel, mentally stimulating activities for 10-12 weeks and were compared to a control condition. Results supported the hypothesis; the experimental group showed greater pre- to post-CCF gain than did controls (effect size d=0.56), with a similar gain on a spatial-perceptual task (WAIS-R Blocks). Even brief periods of increased cognitive stimulation can improve older adults' problem solving and flexible thinking.

  • Tranter and Koutstaal (2008) found that older adults introduced to mentally stimulating activities showed greater gains on a measure of fluid intelligence than a control group.

    “They found that, when compared with a control group, the experimental group showed greater gains on a measure of fluid intelligence, suggesting that engaging in mentally stimulating activities for a short period is indeed beneficial to cognition.”

  • When individuals participate in a cognitive-training program, beneficial effects on cognitive performance tend to be relatively narrow, usually localized to the specific cognitive test trained.

    “For instance, research suggests that when individuals participate in a cognitive-training program, the beneficial effects on cognitive performance tend to be relatively narrow in scope, usually localized to the specific cognitive test that was trained (e.g., Ball et al., 2002; Willis et al., 2006; but see Tranter & Koutstaal, 2008).”
  • The CCFT is considered a superior and more specific measure of fluid intelligence compared to measures using only matrix tasks.

    “The CCFT is considered a superior and more specific measure of fluid intelligence compared to measures using only matrix tasks [45,46]”

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.
