who carried this research
baddeley
what did baddeley and hitch say
STM was not just 1 store but number of difference stores
says if do 2 things same time and both are visual tasks, you perform less well than if separate
central executive
is to direct attention to particular tasks. keep eye on everything that’s going on and deal with tasks requiring attention.
HAS LIMITED CAPACITY
phonological loop
LIMITED CAPACITY
code speech sounds, involving maintenance rehearsal, deals with auditory info,
phonological store inner ear
articulately process inner voice
visuo spatial sketchpad
codes visual info in terms of separate objects as well as to arrange, VISUAL/SPATIAL INFO IS TEMPORARY STORed HERE.
visual- what thins looks like
spatial - physical relationships between things
LOGIE said divided into a visual cache which stores info about visual items eg colours
inner scribe which stores arrangement of object in visual field
episodic buffer
received input from sources TEMPORARILY stores and then integrates in order to construct.
NO CAPACITY
both visual and acoustic info.
lim
problems with using case studies
problems with using evidence from case studies of individuals who suffered from brain damage
this is can change behaviour and perfomr worse on task, or can find it difficult paying attention and underperform in tasks
evidence from brain damage patients
SHALLICE AND WARRINGTON studied man stm was greater than visual stimuli. his brain damage seemed to be restricted to phonological loop, another patient who had been involved in road accident performed better on spatial raid than those involving visual imagery
