What is coding
coding is the way in which information is stored
what is duration
duration is the period of time information can be stored
What is capacity
capacity refers to the amount of information that can be stored in the stm at one time
what are the three ways information can be coded
acoustically
semantically
visually
coding study
braddeley
describe braddeleys study
had 4 groups who had to learn and then recall words which were either :
1) semantically similar
2) semantically different
3) acoustically similar
4)acoustically different
participants were either asked to recall words immediately or after 20 mins
What did braddeley conclude
that the stm encoded information semantically and the LTM encoded information acoustically
Capacity study
Miller
what is miller say
that the capacity of STM is 7 +- 2
chunking helps remember info
Jacobs digit span
asked to recall sequence of numbers
after each correct recall another number was added
What was the average recall of jacobs digit span
9.3
what is the duration of the STM
18s
LTM duration ?
unlimited
Bahricks LTM duration
participants aged 17yr to 74yrs asked to identify schoolmates
15yr duration = %60 accuracy
48yr duration = 30%
