This is a measure of how much can be held in memory. It is represented in terms of bits of information, such as number of digits.

Coding
The way information is changed so that it can be stored in memory. Information enters the brain via the senses. It is then stored in various forms such as visual (pictures), acoustic (sounds), or semantic (meaning of experience) codes.
2 of 15
Duration
A measure of how long a memory lasts before it is no longer available.
3 of 15
Long-term memory (LTM)
Your memory for events that have happened in the past. LTM has potentially unlimited duration and capacity and tends to be coded semantically.
4 of 15
Short-term memory (STM)
Your memory for immediate events. STMs are measured in seconds and minutes rather than hours and days. They disappear unless rehearsed. STM also has a limited capacity of about four chunks of information and tends to be coded acoustically.
5 of 15
Multi-store model
An explanation of memory based on three separate memory stores, and how information is transferred between these stores.
6 of 15
Sensory register
This is the information at the senses. Information is retained for a brief period. We are only able to hold accurate images of sensory information momentarily. The capacity is very large and the method of coding depends on the organ involved.
7 of 15
Central executive
Monitors and co-ordinates all other mental functions in working memory.
8 of 15
Episodic buffer
Receives input from many sources, temporarily stores this information, and then integrates it in order to construct a mental episode of what is being experienced.
9 of 15
Phonological loop
Codes speech sounds in working memory, typically involving maintenance rehearsal.
10 of 15
Visuo-spatial sketchpad
Codes visual information in terms of separate objects as well as the arrangement of these objects in one's visual field.
11 of 15
Working memory model
An explanation of the memory used when working on a task. Each store is qualitatively different.
12 of 15
Episodic memory
Personal memories of events, such as what you did yesterday or a teacher you liked. This kind of memory includes contextual details plus emotional tone.
13 of 15
Procedural memory
Memory for how to do things, for example riding a bicycle or learning how to read. Such memories are automatic as the result of repeated practice.
14 of 15
Semantic memory
Shared memories for facts and knowledge. These memories may be concrete such as knowing that ice is made of water, or abstract, such as mathematical knowledge.
