Memory AO1 Flashcards
How does the sensory register code?
Modality specific (e.g visual-iconic)
How does the short term memory code?
Acoustic
How does the long term memory code?
Semantic
What is the capacity of the sensory register?
Unlimited
What is the capacity of the short term memory?
5-9 items (7+/-2 items )
What is the capacity of the long term memory?
Unlimited
What is the duration of the sensory register?
Limited, less than 0.5 seconds
What is the duration of short term memory?
Limited 18-30 seconds
What is the duration of long term memory?
Potentially forever
What is coding?
The way we process information so it can be stored
What does capacity mean?
This is the amount of information that can be held in memory
What does duration mean?
This is how long the information lasts in memory
Who did research on coding of STM and the procedure?
Baddeley investigated how we code information in our STM and he did this by showing ppts lists of words in 4 categories;
Acoustically similar +dissimilar
Semantically similar+dissimilar
Immediately after ppts asked to recall list in correct order.
What did baddeley find and conclude form investigating coding in STM?
He found that ppts made more mistakes on acoustically similar list and concluded STM mainly coded info acoustically l.
