The Psychology and Neuroscience of Forgetting

Wixted, John T.·2004·Annual Review of Psychology

Abstract

Traditional theories of forgetting are wedded to the notion that cue-overload interference procedures (often involving the A-B, A-C list-learning paradigm) capture the most important elements of forgetting in everyday life. However, findings from a century of work in psychology, psychopharmacology, and neuroscience converge on the notion that such procedures may pertain mainly to forgetting in the laboratory and that everyday forgetting is attributable to an altogether different form of interference. According to this idea, recently formed memories that have not yet had a chance to consolidate are vulnerable to the interfering force of mental activity and memory formation (even if the interfering activity is not similar to the previously learned material). This account helps to explain why sleep, alcohol, and benzodiazepines all improve memory for a recently learned list, and it is consistent with recent work on the variables that affect the induction and maintenance of long-term potentiation in the hippocampus.

  • Natural forgetting is an adaptive feature that prevents cognitive overload, maintains information relevance, and enables efficient generalization by removing specific details while preserving important patterns.

    “This natural forgetting is not a weakness but an adaptive feature that prevents cognitive overload, maintains information relevance, and enables efficient generalization by removing specific details while preserving important patterns [19].”

  • Testing forestalls forgetting, unlike many other independent variables (e.g., meaningfulness) that do not influence forgetting rate.

    “It has been argued that testing forestalls forgetting, unlike many other independent variables (e.g., meaningfulness) that do not influence forgetting rate (Underwood 1972, Wixted 2004).”

  • The consolidation hypothesis is now widely accepted based on numerous studies showing that psychological, pharmacological, and electrophysiological manipulations can effectively impair or enhance memory when administered after encoding.

    “The consolidation hypothesis is now widely accepted based on numerous studies showing that psychological, pharmacological, and electrophysiological manipulations, such as interference learning, the administration of norepinephrine and protein synthesis inhibitors or electroconvulsive shocks, can effectively impair or enhance memory, when administered after encoding (e.g., Refs. 803, 1332).”

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.
