Abstract

The discovery that experience-driven changes in the human brain can occur from a neural to a cortical level throughout the lifespan has stimulated a proliferation of research into how neural function changes in response to experience, enabled by neuroimaging methods such as positron emission tomography and functional magnetic resonance imaging. Studies attempt to characterize these changes by examining how practice on a task affects the functional anatomy underlying performance. Results are incongruous, including patterns of increases, decreases and functional reorganization of regional activations. Following an extensive review of the practice-effects literature, we distinguish a number of factors affecting the pattern of practice effects observed, including the effects of task domain, changes at the level of behavioural and cognitive processes, the time-window of imaging and practice, and of a number of other influences and miscellaneous confounding factors. We make a novel distinction between patterns of reorganization and redistribution as effects of task practice on brain activation, and emphasize the need for careful attention to practice-related changes occurring on the behavioural, cognitive and neural levels of analysis. Finally, we suggest that functional and effective connectivity analyses may make important contributions to our understanding of changes in functional anatomy occurring as a result of practice on tasks.

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

  • Reduced activation in SFG and R-MFG may indicate diminished control demands with training or shifts in processing mode.

    “Similarly, reduced activation in the SFG and R–MFG—prefrontal nodes involved in sustained attention, updating, and interference control—may indicate diminished control demands with training or shifts in processing mode67,75,76.”
  • Kelly and Garavan noted that decreases are often observed in prefrontal and parietal areas associated with attentional control, increases have generally been seen in premotor and motor areas during motor tasks, and a redistribution is often found in tasks where different cognitive processes operate during early and late training.

    “Kelly and Garavan [51] noted that decreases are often observed in prefrontal and parietal areas associated with attentional control, increases have generally been seen in premotor and motor areas during motor tasks, and a redistribution is often found in tasks where different cognitive processes operate during early and late training [61, 63].”

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.
