Study Notes

Understanding Forgetting and Memory Decay

  • Memory fades over time due to natural decay of physical structures in the brain, including patterns of atoms and molecules.
  • Heating environments can accelerate memory decay, as demonstrated in a study with fish where increased tank temperatures led to faster dissolution of memory structures.

Interference in Memory

  • Interference occurs when new information disrupts the recall of previously learned material, especially with similar types of information.
  • Examples of interference: learning a new phone number can hinder the ability to remember an older number, but unrelated concepts (like dance moves) do not interfere.

Changes in Retrieval Cues

  • As time passes, retrieval cues can change due to factors like moving homes and workplaces, leading to fading memories connected to outdated cues.
  • Childhood amnesia is linked to multiple factors, including the passage of time, interference from new memories, and changes in retrieval cues.

Childhood Amnesia

  • Generally affects memories from before the age of two or three.
  • Factors influencing childhood amnesia may include language development, which can alter memory capabilities, and brain maturation processes.

Amnesia and Brain Damage

  • Amnesia portrayed in films (e.g., Eternal Sunshine of the Spotless Mind, The Bourne Identity) reflects real-life cases of memory loss.
  • Two primary types of amnesia exist:
    • Retrograde Amnesia: Loss of memory for events before an incident (like trauma).
    • Anterograde Amnesia: Inability to form new memories after an event.

Case Study: Clive Wearing

  • Clive Wearing suffered severe brain damage from viral encephalitis, affecting key brain areas, including both temporal lobes and the hippocampus.
  • He retains no long-term memory and struggles to form new memories, experiencing life on a moment-to-moment basis, akin to constant rebirth.

Clive's Daily Experience

  • Clive documents every moment he perceives as awake in a diary, as he has no recollection of prior entries.
  • He emphasizes the newness of each awakening, interpreting previous experiences as irrelevant or unrecognizable.
  • Clive’s accounts reveal no memories of dreams or continuity, underscoring the depth of his amnesia and the fragility of human memory.

Memory and Forgetting

  • Memory fades over time due to physical decay of molecular structures in the brain.
  • An experiment demonstrated that heating the water temperature in a fish tank increased forgetting due to accelerated molecular dissolution.
  • Interference from new information can disrupt memory recall; similar types of information affect retention more significantly than dissimilar information.
  • Retrieval cues change over time, impacting memory; relocation and changes in surroundings may hinder access to past memories.
  • Childhood amnesia, where memories before age two or three are typically forgotten, arises from time passage, interference, and changes in retrieval cues.
  • Language acquisition might transform memory processes, complicating the recollection of pre-linguistic memories.
  • Brain maturation may contribute to the effects of childhood amnesia.

Types of Amnesia

  • Retrograde amnesia involves loss of memories before an incident (e.g., trauma or stroke); often depicted in films like "Jason Bourne."
  • Anterograde amnesia leads to an inability to form new memories, causing individuals to lose their sense of continuity in life.
  • Clive Wearing, a notable case of anterograde amnesia, lost both past memories and the ability to create new ones due to brain damage from viral encephalitis.
  • Wearing records diary entries as a compulsive way to track his consciousness, perceiving each moment as an entirely new experience.

Implicit and Explicit Memory

  • Individuals with anterograde amnesia may still develop implicit memories, allowing them to learn skills without conscious awareness.
  • Practical tasks, such as mirror drawing, demonstrate that even amnesic individuals can improve with practice despite lacking explicit memory of learning.
  • Famous patient HM provided insight into amnesia, showcasing that new skills can be acquired without the individual acknowledging prior learning.
  • The film "Memento" explores the distinction between explicit and implicit memory, highlighting the complexity of memory systems.
