coding, capacity and duration

• what is memory 


  the ability to take info, store it and then recall it at a later point
• what’s the three words that come under “what is memory”

  encoding, storage , retrieval
• what does semantic mean


  meaning
• what does acoustic mean 


  sound
• what does coding mean


  how the info is processed to get into the store
• how do we encode info


  from our five senses
• how does the STM encode info


  acoustically
• how does the LTM encode info 


  semantically
• what research has been done on coding in STM 


  baddeley (1966) gave participants 6 letter sequences to remember
• what research has been done on coding LTM 


  baddeley gave participants a list of semantically similar or dissimilar words
• how can we evaluate research into coding?

  well controlled

  ecological validity

  
• what does capacity mean


  the amount of info the store can hold

  it’s unlimited and takes in everything from senses
• what research has been done on the capacity of STM


  Miller (1956) concluded that the capacity of the STM is about 5-9 items
• what research has been done about chunking?


  grouping info to make it meaning and more helpful to remember
• what research has been found about digit span?


  -miller (1956) research is supported by jacob’s (1887)

  -used where participants were given one letter or number to recall, if they got it right they were given 2 to recall this kept going until the participants would make a mistake in recall
• evaluation of capacity in STM


  (the graph)

  
• what is duration 


  how long info lasts in the store
