capacity

• P: one criticism of the research investigating STM is that Miller's original findings have not been replicated

  E: Cowan reviewed a variety of studies on the capacity of STM and concluded that STM is likely to be limited to 4 chunks. research on the capacity of STM for visual information also found that 4 items was the limit

  L: this suggests that STM may not be as extensive as we thought
• P: it seems that the size of the chunk affects how many chunks you can remember

  E: simon found that people had a shorter memory span for larger chunks, such as 8 word phrases, than smaller chunks such as one syllable words

  L: this continues to support the view that STM has a limited capacity and refines our understanding
