PSYCH MOCK MEMORY LONG ANSWER Q

WMM

what is the working memory model

a model which builds upon the MSM by proposing a more complex short term memory

name the components of the WMM

central executive episodic buffer phonological loop visuo spatial sketchpad LTM

what is the central executive

the control center that monitors incoming information and uses reasoning to allocate to slave systems

central executive CO CA

modal one strand

what is the visuo spatial sketchpad

slave system that holds static images from the inner eye

visuo spatial sketchpad CO CA

visual 4 objects

what is the phonological loop

slave system that holds and rehearses acoustic information

what does the phonological loop split into

primary acoustic store and articulatory process

what is the function of the primary acoustic store

process words you hear

what is the function of the articulatory process

maintenance rehearsal

what is the episodic buffer

a temporary store of information that links the slave systems and the LTM to wider processes

strength of the WMM

supporting study of brain damage patient KF

supporting study WMM

a patient whos short term memory was damaged showed variation in levels of forgetting between visual and auditory stimuli.auditory problems were also limited to verbal material like numbers showing damage was limited to the PL

what does d’espositos study say

MRI scanning showed the prefrontal cortex was activated when verbal and spatial tasks were performed simultaneously but not separately showing the area is associated with the CE

weakness of the WMM

lack of info on the CE

what study demonstrates the lack of info on the CE

Eslinger and Damasio

outline Eslinger and Damasio’s study

they studied a person who had a brain tumour removed who could use reasoning skills but couldn’t make decisions.

explain how eslinger and damasios study shows that there are issues with the CE

use of reasoning skills shows CR is intact but inability to make decisions shows its not
