Evaluation
++ Research
Glanser and Cunitz presented 2 groups of participants with the same list of words/ Participants remembered the first and last few words but not the middle words. This is because the first words were put into the LTM through the primacy effect and the last were in the shirt term memory (recency effect).
Implies the long and short term are seperate stores
++ Naturalistic research
HM - removed temporal lobes and couldn't form new long term mem. had good short term mem.
-- Alternative theories
WMM
-- Hypothetical
Neglects the processes of memory
