Forgetting

The Many Faces of Forgetting: Toward a Constructive View of Forgetting in Everyday Life

Authors: Fawcett & Hulbert, 2020

Forgetting

  • Fundamental Questions
    • Is forgetting always bad?
    • No. There are complex implications surrounding forgetting in cognitive functioning.
  • Problems with Memory
    • Inability to remember and the inability to forget can both present problems.
  • Positive Aspects of Forgetting
    • Forgetting contributes significantly to our well-being:
    • Guardian: Helps in forgetting negative thoughts promoting a positive self-image.
    • Librarian: Aids in organizing thoughts.
    • Inventor: Supports creativity and flexible thinking.

Mechanisms of Forgetting

  • Pre-encoding Forgetting

    • Occurs when information is not attended to.
    • Happens shortly after encoding when a piece of information is deemed irrelevant.
    • Item method directed forgetting employed.

  • Post-encoding Forgetting

    • Decay: Memory fades over time.
    • Interference: Similarity between information interferes with storage or retrieval (example: multiple visits to the same location).
    • Cue Appropriateness: Retrieval might fail due to inappropriate or changed cues between encoding and retrieval. (example: context shifts)
    • Inhibition: Information is actively suppressed, complicating retrieval efforts.
    • Retrieval-Induced Forgetting (RIF): A phenomenon where recalling certain memories can lead to forgetting related memories.
    • Think/No-Think (TNT): A paradigm that illustrates suppression-induced forgetting (SIF).

The Guardian: Serenity and Stability

  • Cultural Maxim: "Time heals all wounds"
    • The process of forgetting thoughts and feelings tied to negative experiences is crucial for emotional well-being.
  • Highly Superior Autobiographical Memory (HSAM)
    • Individuals with HSAM struggle with this aspect of forgetting.
  • Variability in Memory Suppression Abilities
    • Individual differences exist in the capacity to suppress memories. Poor memory control is often associated with:
    • Rumination.
    • Worry.
    • PTSD diagnosis.
    • Individuals exhibiting poor memory control may be overrepresented in various clinical populations.
  • Challenges of Suppression
    • Suppressing unwanted thoughts may not be a helpful strategy unless appropriate support systems are in place (referencing Marsh et al., 2018).

The Guardian: Self-schema Changes

  • Self-perception Over Time
    • Self-schemas evolve and often minimize past behaviors inconsistent with the current self.
    • Example: Bad grades may be misremembered as better than reality.
    • Forgetting past embarrassments, while focusing on positive experiences, can render the embarrassing details difficult to access over time.

The Librarian: Organization

  • Functionality of Memory in the Present
    • Memory is essential for functioning and helps prioritize what information is stored for easy retrieval while allowing regular information to be forgotten when it is not required.
    • Example: Specific details, like those of coins, tend to be forgotten unless pertinent to current functionality.
  • Retrieval of Memories
    • Recent experiences that are more relevant and current are easier to retrieve compared to distant memories.
    • Contextual Cues: A distinctive sight, smell, or location can facilitate access to autobiographical memories that may otherwise remain inaccessible.

Reconsolidation

  • Memory Alteration
    • Once memories are retrieved, they can be changed and re-stored differently.
    • Study Reference: Hupach et al., 2007 exemplify this through a study involving two lists:
    • Study List 1.
    • Delay of two days.
    • Study List 2 presented.
    • Either reminded of List 1 or not after another two-day delay before recall of List 1.

The Librarian: Generalized Representation Development

  • From Episodic to Semantic Memory
    • Involves creating an abstract, generalized representation based on numerous specific, detailed instances.
    • Encoding the general gist may entail forgetting verbatim details.
    • Fuzzy-trace Theory: Brainerd & Reyna, 2002 discusses how understanding the general reference can lead to more robust memory retention.
    • The Testing Effect: Repeated retrieval can aid in the generalization of knowledge.

The Inventor: Exploration and Creativity

  • Functional Fixedness Overcoming
    • Individuals demonstrating greater Retrieval-Induced Forgetting (RIF) show enhanced performance on the Remote Associates Test (RAT).
    • Example: The words "cottage – swiss – cake" demonstrate how forgetting misleading associates may assist in generating solutions.
    • Individuals with lower RIF perform comparably on RAT but often need longer breaks between tasks.
    • Intentional Forgetting: Ability to selectively forget certain associates can lead to more efficient problem-solving capabilities.
  • Nostalgia: Positive feelings of re-engaging with the past rely on forgetting specific details to experience pleasant emotions.

Forgetting: Conclusions

  • Cognitive Feature: Forgetting is fundamentally a feature of cognition rather than a mere flaw.
  • Social Media Impact: Social media platforms, with their unerring records and automatic reminders, can inhibit natural forgetting processes.
    • Relevant issues include bullying and job applications.
  • Overall Importance of Forgetting: Forgetting tends to be beneficial, creating pathways for generalizations, facilitating current thinking, and enhancing creative thought processes.
