Memory Systems
- Ability to encode and retrieve information
Two component memory model
- Memory composed of two systems:
o Working memory (sometimes short term memory)
Info stored for short periods of time
o Long-term memory
WM: neurological sketchpad
- Holding space where info can be accessed for immediate processing
- Limited capacity
- Subsystems hold different kinds of information: central executive, phonological loop, visuospatial
Central executive
- Coordinates operations of working memory
- Doesn’t store information, attends to info deciding what needs to be remembered, and sends to
appropriate system
Phonological loop
- Spoken and written material
- Holds it in speech-based form
- Two components: articulatory control process (minds voice), phonological store (minds ear)
Visuospatial sketchpad
- Stores what things look like (size, shape, texture), spatial info, movement info
- Constantly changing why it is in working memory
Working memory
- Two characteristics
o Duration how long it’s held
Has limited duration if rehearsing is prevented
Error increases with retention interval
20-30 seconds
o Capacity how much is held
Miller’s law
Average number of items between 5-9
“Chunking” information can increase capacity easier to process/store
Limits for movements difficulty remembering beyond 8 movements
Similar to miller’s law
Experts may have long-term WM
- More resistant to interference
- Differentiates experts from novices
