Capacity

subject the amount of information that lot be stored in a memory at any particular time.
utterly verge memory (STM) capacity
* Capacity: 7 +/- 2 items (Miller 1956 suggested that most people store about sevensome commutative or discrete items in short bourn memory. These items may be numbers, letter or words, etc. Miller referred to apiece of these items as chunks.)
* Experiments that investigate capacity traditionally use the series digit span method in which numbers/letters have to recall in the correct order.
Long condition Memory LTM capacity
* Capacity: Unlimited
* Long term memory erect hold vast amount of information, which can be stored for a lifetime
* LTM is not a passive store of information but rather a dynamic store that consonantly revise and modified stored information
* Its not possible to quantify the capacity of LTM
* Capacity of LTM has to be organised otherwise it would be embarrassing to retrieve
* Possible to lose information such as a process of decay

* Digit Span Technique: a way of life of measuring capacity in STM.



Participants have to repeat back up strings of digits (that increase in size) until they can no long-lived repeat the sequence of digits correctly
Factors Affecting Capacity:
* Influence of long- term memory Repeating a digit string can help the STM temporarily because some of the information is be committed to the LTM already and so is easier to remember.
* Reading clamorously you have heard it and seen it by reading.
* Rhythmic class grouping numbers or ideas into rhythmic sets.
