Experimental evidence for MSM

As you have now learned, there is some support for MSM from case studies but this type of evidence as many flaws, not least that the data may not be generalisable given that they are performed on unique individuals who may nt be representative of the majority of people with that specific type of brain injury for some particular reason. This means that the evidence that they provide for MSM is questionable.

In your essay about MSM, you may therefore wish to examine experimental evidence which has the advantage of having higher internal validity, reliability and generalisability.

Use the following worksheet to learn about numerous experimental studies that have been used to support MSM’s claims about the differences between short and long terms memory with regard to coding, capacity and duration, but also the idea that rehearsal is necessary in order for information to move from STM to LTM.

This handout contains information about Murdock’s serial position curve which can be explained using MSM, thus strengthening the explanatory value of the theory. If you would like to replicate this study, you could use the word list contained in the following document.

Glanzer and Cunitz (1966) is also mentioned in the handout; this study introduced an interference task between the presentation of the word list and the free recall task. As the participants were unable to sub-vocally rehearse the final few words in the list whilst completing the interference task, the recency effect was all bit eliminated. This highlights the importance of rehearsal if information contained in STM is to transfer successfully to LTM (which is necessary for recall of information over 30 seconds subsequent to encoding and storage).

The following google slides show was created using pear deck for the interactive elements and maybe useful to support online learning. It was designed for synchronous work but could easily be adapted fr asynchronous work. There are also answers/directions in the notes section on some of the slides: https://docs.google.com/presentation/d/1DjifoHQuuBTHFtBG7iPSErlQ3VKx5FkNqujFqL4iUH4/edit?usp=sharing

There is also a model SAQ here which uses Glanzer and Cunitz as the example research study:
