Flashcards

Chess Expert Memory

Chess experts have superior memory for chess games compared to meaningless games, due to semantic (meaning-based) memory for chess.

Episodic Memory

Memory that allows updating of impressions based on new info.

Semantic Memory

Memory for facts and general knowledge, like the rules of chess.

H.M. Case Study

Patient with severe amnesia, impacting memory, showing distinct memory functions.

Study Notes

Types of Memory

  • Memory is not a single entity, but rather a collection of interacting systems.
  • Spatial metaphors are used to understand memory (capacity, duration).
  • Atkinson & Shiffrin's Modal Model proposes separate memory stores (sensory store, working memory, long-term memory).
  • Short-term store (STS) and long-term store (LTS) are functionally independent, and can be dissociated clinically.
  • Long-term memory has different subtypes: episodic, semantic, and procedural.
  • Episodic memory involves personal experiences ("remember").
  • Semantic memory involves facts and general knowledge ("know").
  • Procedural memory involves skills and habits (implicit knowledge).

Some Experiments in Memory

  • Ebbinghaus's CVCs study revealed rapid forgetting, exhibiting a forgetting curve.
  • War of the Ghosts study by Bartlett showed that memory is constructive, not a precise reproduction. People interpret information and fill in gaps based on prior knowledge, resulting in distortions and modifications compared to the original.
  • Chess Master Study: Chess experts showed superior memory for meaningful chess positions, proving that skill and experience contribute significantly to memory performance.
  • Susan Bower study: People show biases in remembering details of an event which is influenced by whether recalling these details in the short-term or long term after an event. Episodic memory allows for updating impressions of people based on new information.

Additional Information

  • Memory can be both unitary and may have multiple components.
  • Clinical studies have shown memory can be disrupted or altered, even in specific areas, suggesting its components are dissociable.
  • Researchers like Bartlett studied how people reconstruct memory, creating an outline of reconstructive memory.
  • The Modal Model of Memory has many assumptions. It is a model often referred to in memory research.
  • Ebbinghaus, 1885, provided key findings regarding memory.
  • Research and models like Atkinson & Shiffrin's Modal Model, Bartlett's work, and Bower's work provide varying perspectives on the nature and function of memory.
