poorly the earlier items reflect LTM
the recency effect reflects STM go from short term(most
recent) to long term
(earlier items) 3 Aside: Why is there a primacy effect?
Rundus (1971) – rehearse out loud during encoding, then recall * the early items in the list were more often rehearsed primacy may be related to the extra rehearsals that the first items in the list receive Dissociating STM and LTM
1) Increase study time ‐ 1 vs. 2 sec/item (Murdock, 1962) * influences the LTM portion of curve but leaves the STM portion unaffected study time dissociates STM and LTM 4 2) Introduce a delay between study and test
(Postman & Philips, 1965)
* influences STM but leaves LTM portion of curve unaffected
delay dissociates STM and LTM 1 & 2 together represent a double dissociation
long term memory and short term memory can be moved around with other messing with each other cognitive control Frontal movement Parietal Me...
