Working Memory Training May Increase Working Memory Capacity but Not Fluid Intelligence

Abstract

Working memory is a critical element of complex cognition, particularly under conditions of distraction and interference. Measures of working memory capacity correlate positively with many measures of real-world cognition, including fluid intelligence. There have been numerous attempts to use training procedures to increase working memory capacity and thereby performance on the real-world tasks that rely on working memory capacity. In the study reported here, we demonstrated that training on complex working memory span tasks leads to improvement on similar tasks with different materials but that such training does not generalize to measures of fluid intelligence.

  • Increases in working memory capacity are typically thought to mediate the effects of working memory training on fluid intelligence or academic attainment.

    “This is because effects of working memory training on fluid intelligence or academic attainment are typically seen as being mediated by (i.e. dependent upon) increases in working memory capacity (Harrison et al., 2013; Lange & Süß, 2015; Tidwell et al., 2014; von Bastian & Oberauer, 2014).”
  • In those studies, active controls showed no gain from baseline and were not better than passive controls, which suggests the null transfer result did not depend on control type.

    “It is important to note, however, that their active control groups did not improve over baseline, nor did they outperform their associated passive control groups, suggesting that the failure to find transfer was irrespective of control type.”

  • Two prominent recent studies that used active control groups did not observe transfer to fluid intelligence.

    “With this in mind, two recent, widely publicized training studies used active controls and failed to find transfer to measures of Gf (Harrison et al., 2013;Redick et al., 2013).”

  • Cognitive training has been shown to have an impact on task performance and on fluid intelligence tests.

    “Cognitive training has shown to have an impact on task performance and on fluid intelligence (Gf) tests [13-15].”
  • The cognitive processes involved in different distractor tasks (e.g., equation verification vs mental rotation) have minimal overlap.

    “The overlap in the cognitive processes involved in performing distractor tasks such as verifying equations and judging whether letters are upright or mirror-reversed when mentally rotated (Harrison et al., 2013) is minimal.”

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.
