define working memory
temporary storage system that allows us to hold and manipulate information for cognitive tasks like reasoning, leaning, and comprehension
4 components of Working Memory Model (Baddeley & Hitch, 1974)
(CPVE)
- central executive
- phonological loop
- visuo-spatial sketchpad
- episodic buffer
define central executive
- control center of working memory that directs attention, coordinate tasks, and allocates resources to other components
- it has limited capacity and does not store the information itself
define phonological loops
responsible for processing the auditory and verbal information
2 subcomponents of phonological loops (PA)
- phonological store
- articulatory rehearsal process
phonological store vs articulatory rehearsal process
phonological store
- holds auditory information
articulation rehearsal process
- refreshes stored information through subvocal repetition
2 key effects of phonological loop:
- phonological similarity effect
- word-length effect
phonological similarity effect vs word-length effect
phonological similarity effect
- memory is worse for words that sound alike
word-length effect
- memory is worse for long words rather than short words
define visuo-spatial sketchpad
stores visual and spatial information
2 components of visuo-spatial sketchpad
- visual cache
- inner scribe
visual cache vs inner scribe (VI)
visual cache
- stores form and color
inner scribe
- processes spatial and movement information; assists in rehearsal
define episodic buffer
integrates information from the phonological loop, visuo-spatial sketchpad and the long term memory
define working memory capacity
refers to how much information can an individual process and store simultaneously
assessments to test working memory capacity
- reading span task
- operation span task
reading span task vs operation span task
reading span task
- recall the last word of multiple sentences
operation span task
- solve math problems while remembering words
key findings about working memory capacity
- high working memory capacity is linked to higher intelligence
- stress and anxiety reduce working memory capacity
neural basis of working memory
- prefrontal cortex
- parietal cortex
- left hemisphere
- frontal lobes
critical for central executive functions
prefrontal cortex
processes phonological information
left hemisphere
involved in visuo-spatial sketchpad tasks
parietal cortex
brain damage to the ____ can lead to dysexecutive syndrome which causes issues in planning, problem solving, and multitasking
frontal lobes
define storage
creation of a permanent record of information
3 stages of storage (SSL)
- sensory store
- short term store
- long term store
define sensory store
- initial repository before the information enters short or long term store
- capable of storing information for very brief periods
