A free recall study done by these researchers supports the MSM of memory. They found that given an interference task after hearing a list of words, causes the recency effect to disappear but the primacy effect is still maintained.
To get full credit: How do their findings support MSM then?
Who are Glanzer and Cunitz.
Supports the existence of a short-term store (the words at the end of the list were in short term store and thus disappeared after an interference task) and supports existence of long-term store. The words at the beginning of list presumably got rehearsed and transferred from STS to LTS.
