To investigate whether the STM and LTM are separate stores.
Procedure
Participants were given a list of 21commonwords to memorise one after another, they were asked to recallasmany as possible.
Findings
Participants remembered more words on average from the beginning (Primacy Effect) and end (Recency) of the list than the middle, This is known as the serial position effect.
Primacy Effect
The tendency to recall information presented at the start of a list better than information at the middle or end
Recency Effect
The tendency to recall later words
Conclusion
Ps remembered more words from the beginning of the list because they had been transferred by rehearsal to the long-term memory. Words at the end of the list were still in the STM. Words in the middle were forgotten because of the limited capacity of the STM (7±2 (Miller))
