Longitudinal Evidence That Increases in Processing Speed and Working Memory Enhance Children's Reasoning

Kail, Robert V.·2007·Psychological Science

Abstract

As children develop, their information-processing speed (PS) increases, and they retain more information in working memory (WM); these changes have been hypothesized to drive age-re-lated improvements in reasoning and problem solving. For example, in Fry and Hale’s (1996) cascade model, develop-mental change in PS increases the functional capacity of WM, which in turn facilitates reasoning. Studies have shown that developmental increases in PS and WM during childhood and adolescence predict developmental improvements in inductive reasoning (Fry & Hale, 1996) and in accuracy on arithmetic word problems (Kail & Hall, 1999). However, although these findings are consistent with the cascade model, they provide relatively weak support because they are based on concurrent correlations derived from cross-sectional studies. The present work was designed to provide a stronger test of the cascade

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?

  • The neurocognitive effects show greater maturational effects on speed than on accuracy, consistent with prior studies on age-related performance changes.

    “The neurocognitive effects indicate greater maturational effects on speed than accuracy, which is consistent with multiple studies on age-related changes in performance across the lifespan (Kail 2007;Coyle et al. 2011).”

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.
