Memory Flashcards
Multi Store model
An explanation of memory that sees information flowing through a series of storage systems
Coding
The means by which information is represented in memory
Capacity
The amount of information that can be stored at a given time
Duration
The length of time information remains within storage
Memory
The means by which the mind stores and retrieves information and events experienced
Sensory register (SR)
A short-duration store holding impressions of information received by the senses
Short-term memory (STM)
A temporary store holding small amounts of information for brief periods
Long-term memory (LTM)
A permanent store holding limitless amounts of information for long periods
Coding in SR
Information is stored in a raw, unprocessed form, Information that is paid attention to passes on to the STM.
Capacity in SR
The capacity of each sensory memory store is very small, with the information contained being in a processed, highly detailed and ever-changing format.
Duration in SR
All sensory memory stores have limited duration, though the actual duration of each store in not constant.
Coding in STM
Visually, Acoustically or Semantically
Capacity of STM
Limited capacity, between five and nine items can be held (7+-2), can be increased by chunking letters
Duration of STM
Information remains in STM for 18-30 seconds, increased by rehearsal
Coding of LTM
Coding is stronger and much deeper, verbal material is mainly semantic, as well as visual and acoustic code
Capacity of LTM
Potential capacity is unlimited, information may be lost due to decay and interference
Duration of LTM
Depends on an individuals lifespan, as memories can last a lifetime
Visually
By thinking of the image of a platypus
Acoustically
By repeatedly saying ‘platypus’
Semantically
By using a knowledge of platypuses, such as their being venomous egg-laying aquatic marsupials that hunt prey through electrolocation
Chunking
Method of increasing STM capacity by grouping information into larger units
Retrieval
The recall of stored memories

Episodic memory
A long-term memory store for personal events. Memories from this store have to be retrieved consciously and with effort
Semantic memory
A long-term memory store from our knowledge of the world. These memories usually also need to be recalled deliberately
Procedural memory
A long-term memory store for our knowledge of how to do things. We usually recall these memories without making a conscious or deliberate effort

Working memory model
An explanation that sees short-term memory as an active store holding several pieces of information simultaneously
Central executive (CE)
Component of the WMM that oversees and co-ordinates the components of working memory
Phonological loop (PL)
Component of the WMM that deals with auditory information
