memory- memory models Flashcards
MSM
strength- research support for separate LTM and STM (2)
-baddeleys research showed STM coding is acoustic, LTM coding is semantic
-supports MSM’s view that STM+LTM are separate and independent
MSM
strength- research support for separate LTM and STM COUNTERPOINT (2)
-artificial materials in studies that support MSM (jacobs, baddeley, peterson+peterson)
-lacks mundane realism (tasks arent reflective of everyday memory tasks)–>cant be generalised (its not a good explanation of how memory works)
MSM
criticism-more than one STM type (2)
-KF study: KF had amnesia- STM recall for digits was poor when they were read out to him (auditory) but recall was better when he read them to himself (visual)
-MSM is inaccurate as there are multiple STM stores and it isnt unitary
MSM
criticism- more than one rehearsal- elaborative rehearsal (4)
-prolonged rehearsal not needed to transfer to LTM
-researchers found type of rehearsal is more important than amount
-elaborative rehearsal= link info to existing knowledge
-MSM doesnt fully explain how LTM storage is achieved
WMM
strength- research support for multiple WMM stores (4)
-researchers supported existence of visuospatial sketchpad
-p’s did visual+verbal task simultaneously and performance wasnt affects
-p’s did 2 similar tasks (both visual/verbal) and performance declined substantially
-similar tasks compete for same slave system- must be separate subsystems for visual and verbal info
WMM
strength: research support- clinical evidence (3)
-KF study supports existence of separate visual+acoustic stores
-KF had amnesia- STM recall for digits was poor when they were read out to him (auditory) but recall was better when he read them to himself (visual)
-damaged phonological loop but visuospatial sketchpad was intact
WMM
criticism- CE isnt well known- questions validity of model (4)
-has limited capacity but it hasnt been quantified experimentally
-EVR study- he had a brain tumour removed. Performed well on reasoning tasks, had problems with decision making
-EVR’s CE was damaged+intact
-baddeley claims CE is most important but least understood component
