How much information can we store, or hold in, STM?
George Miller (1956) “The Magical Number Seven Plus or Minus Two: Some Limits on Our Capacity for Processing Information”
-Miller proposed that STM can store 7 ± 2 units of information for a short period of
  time
-How do we overcome this limit?
 -chunking –
-chunking is best when it is meaningful
       Examples
 

What is the format of information in STM?
 -acoustic/verbal code
     -Conrad (1964) –
     -Baddeley – country names experiment

When we recall information from STM, what is most likely to be recalled?
-serial position curve –
-primacy effects –
-recency effects –

How do we lose information from STM?
-decay
     -Brown (1958), Peterson & Peterson (1959)
     -Brown-Peterson task
     -method

    -results –
    -Brown, Peterson & Peterson interpretation – decay –

-what about interference?

-Waugh & Norman (1965) did an experiment to see what was causing loss
  of information from STM – decay or interference
-method

-results –
-Waugh & Norman concluded that the Brown (1958) and Peterson &
  Peterson (1959) results were due to interference
 -2 types of interference
 1. proactive –
 2. retroactive –

What type of interference best explains the results of Brown
  and Peterson & Peterson?  Why?
    
          -release from PI (proactive interference, Wickens, 1972)
          -method

          -results –
