evaluate the working model of memory (Alan Baddeley and Graham Hitch 1974), including the central executive, phonological loop, visuospatial sketchpad, and episodic buffer

who proposed the working model of memory

Baddeley and Hitch 1974

phonological loop - auditory working memory

retains things we hear

allows us to hear how things sound in our mind

helps us understand a sentence of more than a few words

Visuospatial sketchpad - visual working memory

retains things we have seen

helps us picture how things look

Central executive CE - control centre

puts everything together - controls our attention

puts together sounds and vision

Inhibition - CE

screening of irrelevant info

switching - CE

changing our attention from one thing to another

Updating

modifying info from long term memory

recommitting things to memory through episodic buffer

Episodic buffer

helps retrieve info from long term memory

bridge btwn auditory and visual info

encodes new info into long term memory

Strengths of working model memory model

accounts for ability to store and actively process info simultaneously

explains ability to multi task

limitations of working model memory model

central executive most important but least known about it

cannot specify specific function of central executive
