Working Memory Flashcards
The manipulation and application of working memory for planning task switching attention stimulus selection and the inhibition of inappropriate reflexive behaviors
Cognitive control
The active and temperature representation of info that is maintained for short term to help us think and decide what to do next
Working memory
Sensory memories
Brief transient sensations of what you just perceived
Short term memory or the info you are currently working with
Working memory
STM capacity:
7 plus or minus 2
5-9 pieces of info (chunks)
Finding meaningful info in STM
Chunking (recoding)
3 components of working memory:
Phonological loop
Sketch pad
Central executive
Word length effect
Less capacity to memorize lists of multiple syllable words compared to single syllable words
Transient memories are processed in two stages:
Sensory memory
STM (working memory)
Central executive
Cognitive control; manipulation of remembered info, planning, behavior elevation/inhibition
Visuospatial sketchpad
“Minds eye” visual system for working with info taken in from sensory store or retrieved from LTM
Phonological loop
“Minds ear” 2s long auditory system for working with remembered auditory info
Brain structure thought to play dominant role in working memory
PFC
Dysexecutive syndrome
Frontal cortex damage equals a decrease in working memory and executive function
Phonological loop is located in the
Left hemisphere
