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retrieval cues can change due to factors like moving homes and workplaces, leading to fading memories connected to outdated cues.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.
