Primacy effect = remembering words at the beginning of a list because they are in LTM.
Recently effect = remembering words at the end of a list because they are in STM.
Glazer and Cunitz 1966
Procedure: Participants were shown a list of words, one at a time and then asked to free recall the words. One group free recalled immediately and the other group free recalled after 30 seconds delay with no rehearsal (prevented by counting).
Findings: the group who immediately recalled showed primacy effect and recency effect. The group who recalled after a delay showed only primacy effect.
Conclusion: Both groups remembered words at the beginning of the list because they were in long term memory. But the delay group didn't remember the words at the end of the list because they were not able to maintain the words in short term memory. This shows there are two different stores of memory.
