Study Notes
Memory: Introduction
- Memory is the ability to store and recall information.
- Memory failure is commonly experienced, for example forgetting a neighbor’s name, forgetting to tell a friend about a book to get for college, forgetting to pick up a brother after school, or forgetting to pay a friend for a loan.
Clive Wearing
- Clive Wearing, a famous example of memory loss, suffered from a compromised ability to form new memories (anterograde amnesia).
Key Components of Memory
- There are three crucial parts:
- Encoding: How gets information into memory
- Storage: How information is maintained in memory
- Retrieval: How information is accessed from memory
Encoding
- Attention is critical to encoding.
- Divided attention hinders memory.
- Encoding can be categorized by levels of processing:
- Shallow: focusing on the physical appearance of information (e.g., the shape of a word).
- Intermediate: focusing on the sound of information (e.g., the sound of a word).
- Deep: focusing on the meaning of information (e.g., understanding the concept behind a word).
- Deeper levels of processing result in longer-lasting memory codes.
Storage
- Computer metaphors influenced models of memory storage, particularly the information processing models.
- The multi-store model by Atkinson and Shiffrin (1970s) is a widely accepted theory.
- It proposes three distinct stores:
- Sensory Memory: brief preservation of auditory, tactile, or visual information, lasting only milliseconds or seconds.
- Short-Term Memory (STM): has limited capacity, holding around 7 ± 2 units of information (Miller’s Law), and a limited duration of about 20 seconds, unless rehearsed.
- Long-Term Memory (LTM): holds information indefinitely and has unlimited capacity, with debate regarding if it’s truly permanent due to potential decay, interference, and retrieval failure.
Short-Term Memory as Working Memory
- Working memory, proposed by Baddeley and Hitch (1974), is a more dynamic concept than STM, involving not just rehearsal but also manipulation of information.
Long-Term Memory
- Long-term memory is further organized into logical systems such as declarative and procedural memory.
Clive Wearing and Memory Components
- Encoding: Clive Wearing’s encoding process was severely affected, resulting in his inability to form new memories.
- Working Memory: Clive Wearing’s working memory appears to have remained intact.
- Sensory Memory: It is unclear if Clive Wearing was able to form new sensory memories.
