MSM

• Supporting research from Miller (1959) for the idea of a limited capacity of 5 to 9 items of information in the STM, while Peterson and Peterson (1959) supports the idea of a limited duration in the STM and Bahrick (1975) supports the idea of a lifetime duration in the LTM.

  These studies all support the different elements of MSM and so suggests that the model is an accurate representation of human memory and that STM and LTM are two separate, independent memory stores.
• However, there is evidence to suggest that the MSM is oversimplified.

  For example, the case of KF, who was injured in a motorcycle accident and afterwards was able to recall information from LTM however he had issues with his STM. KF's impairment was mainly for verbal information and his memory for visual information was largely unaffected.

  This suggests that there are at least two separate components within STM which suggests that the MSM may provide an oversimplified account of STM.
• Furthermore, the idea that the MSM is too simple is also supported by Tulving (1985) who proposed that there are three different LTM stores and they each process different kinds of information.

  These findings undermine the model of the LTM in the MSM and suggest that the model is not an accurate representation of memory as previously suggested.
