What is coding?
The format in which information is stored in memory stores
What is duration?
The length of time information can be held in menoryy
What is capacity?
The amount of information that can held in a memory store
What list of words did the group 1 in Baddeleys study have to remember?

Semantically similar words ( great, large, big)
What lists of words did Group 4 in Baddeleys study have to remember?

What did Baddeley find about recall from the STM immediately?
tended to do worse with acoustically similar words
What did Baddeley find about recall from the LTM after 20 minutes ?
They did worse with semantically similar words
What do Baddelys findings suggest?
That information is coded acoustically in STM and semantically in the LTM
How did Jacobs find out how much information the STM can hold at one time?
By measuring participants digit span
What was the procedure for Jacobs digit span test?
The research reads out four digits and participants had to recall this out loud in the correct order» digits increase until participants can no longer remember
What was the mean span for digits across all participants ?
9.3 items
What was the mean span for letters across all participants ?
7.3
What did Miller make observations of ?
everyday practices
