Capacity, Duration And Coding Flashcards
What is Capacity?
The amount of data a store can hold
What is Serial Recall?
A method of testing memory by asking participants to ask them to repeat information in order.
What is Duration?
The length of time a store can hold data
What is Coding?
The way in which Information is changed in order to be stored in memory
Explain the key study:Miller
Used a serial recall task to determine STM capacity and found that most people could remember between 5-9 items (magic number 7).
What relevance does Miller have?
His study demonstrates the capacity of the STM
Explain the study:Peterson & Peterson
Found that 90% of participants could remember a 3-consonant trigram after 3 seconds, but only 2% could recall it after 18 seconds.
What relevance does Peterson & Peterson have?
It demonstrates the duration of the STM.
Explain the study:Bahrick
Investigated the duration of LTM by asking people to recall people from their high school. Even after 48 years, they scored 70% on photo recal.
What relevance does Bahrick have?
It demonstrates the duration of the LTM.
Explain the study:Baddeley
Found that STM and LTM are coded differently - STM are coded acoustically and LTM coded semantically.
What relevance does Baddeley have?
It demonstrates the coding in STM and LTM.
