    • short term memory store
      retains information for an ongoing task
    • duration
      18-30 seconds, limited duration
    • capacity
      limited, 7+-2
    • coding
      sensory and semantic, but main code that short term memory uses is acoustic
    • miller 1956
      suggested that we can sometimes combine individual letters into larger more meaningful chunks
    • chunking
      chunking is when we group individual letters together into meaningful units
    • miller suggested that the capacity of stm is determined by the number of chunks not the number of individual items that we have to recall
    • miller still agreed, however, that the maximum capacity of stm is 7 but isn't limited to 7 individual letters, but 7+-2 chunks of information
    • by chunking we can hugely improve capacity of stm
