working memory model Flashcards
(29 cards)
who came up with the WMM
Baddeley and Hitch- 1974
what is the central executive in the WMM
supervisory component that has overall control of working memory
what is the capacity of the central executive
limited but it can process information from any sensory system
why is the central executive described as an attentional controller in WMM
because it can focus, switch and divide attentions
what does the inner voice do in the phonological loop in WMM
it deals with auditory information
what does the phonological store do in WMM
it holds words that are heard
what does the articulatory loop do in WMM
it maintains acoustic rehearsal
what is the capacity of the phonological loop in WMM
2 seconds worth of what you can say
what is the phonological similarity effect in WMM
where it is more difficult to remember similar sounding words and letters
what is the word length effect in WMM
short monosyllabic words are more likely to be recalled than longer polysyllabic words
what does the visuo-spatial sketchpad do in WMM
it stores visual information for when its required- inner eye
what are the 2 sub-systems of the VSSP in WMM
visual cache and inner scribe
what does the inner scribe do in WMM
records the arrangements of objects in the visual field
what case study supports WMM
KF
what happened to KF
he got in a motorcycle accident and could process visual information but struggled with verbal information
how does KF support in WMM
it supports the existence of 2 separate visual and verbal stores in STM as it seems like his phonological loop is affected but the VSSP isn’t
what are the practical applications of WMM
it has been argued to help children with ADHD by breaking down information into manageable chunks with frequent repetition to help them remember things
how do brain scan studies support WMM
Smith(1995) used brain scans to show how different areas of the brain are active when doing visual or verbal tasks which suggests that the VSSP and the phonological loop are separate systems
name a criticism of the WMM
not all aspects of this model are fully understood which is a weakness as further research is needed
what store supports the phonological similarity effect in WMM
phonological loop
what are the stores in the phonological loop in WMM
what are the stores in the phonological loop
what does the visual cache do in WMM
stores visual data
what is the phonological loop in WMM
slave system that deals with the temporary storage of verbal information
what does the articulatory rehearsal support in WMM
the word length effect
