Making Working Memory Work: A Meta-Analysis of Executive-Control and Working Memory Training in Older Adults

Open access
Karbach, Julia, Verhaeghen, Paul·2014·Psychological Science

Abstract

This meta-analysis examined the effects of process-based executive-function and working memory training (49 articles, 61 independent samples) in older adults (> 60 years). The interventions resulted in significant effects on performance on the trained task and near-transfer tasks; significant results were obtained for the net pretest-to-posttest gain relative to active and passive control groups and for the net effect at posttest relative to active and passive control groups. Far-transfer effects were smaller than near-transfer effects but were significant for the net pretest-to-posttest gain relative to passive control groups and for the net gain at posttest relative to both active and passive control groups. We detected marginally significant differences in training-induced improvements between working memory and executive-function training, but no differences between the training-induced improvements observed in older adults and younger adults, between the benefits associated with adaptive and nonadaptive training, or between the effects in active and passive control conditions. Gains did not vary with total training time.

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

  • Two recent meta-analyses did not find rate of improvement over training to be a significant predictor of transfer.

    “In addition, two recent meta-analyses of working-memory training have not found the rate of improvement over training to be a significant predictor of transfer (Au et al., 2015;Karbach & Verhaeghen, 2014).”
  • Recent research suggests neither length nor number of training sessions nor an adaptive element is necessary for transfer.

    “This is consistent with very recent research suggesting that neither the length nor number of training sessions (Au et al., 2015) nor an adaptive element to training is necessary for transfer (Karbach & Verhaeghen, 2014;Vartanian et al., 2013;von Bastian & Eschen, 2015).”
  • Recent estimates of effect sizes for far transfer to reasoning and fluid intelligence are much smaller than those reported in the earliest working-memory studies.

    “recent estimates of effect sizes especially for far transfer to reasoning and fluid intelligence appear to be much smaller than reported in the earliest working-memory studies.”

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.
