3 fundramental parts of W.M
|
Visuospatial sketch pad (information storage)
Central executive (information processing) Phonological loop (information storage) |
|
|
Phonological loop
|
stores information that can be encoded in acoustic or speech-like format
|
|
|
visuospatial sketch pad
|
stores visual and spatial information
|
|
|
3 keys of Central executive
|
Computational operations on information
Allocation of attention to tasks Acts on information in the storage buffers Pays attention to one buffer or the other |
|
|
Auditory stimuli (in regard to phonological loop)
|
direct access to phonological store
|
|
|
Visual stimuli (in regard to phonological loop)
|
Must be articulated subvocally to produce phonological code..articulate them to yourself..like the digit span task
|
|
|
3 different parts of acoustic similarity (Conrad)..recalling letters in order
This is evidence of phonological loop |
Confusable: the similar sounding letters like B, C, P, T, V
Non-confusable: dissimilar sounding letters Mixed: mixed of similar and dissimilar letters This is evidence for phonological loop |
|
|
Acoustic similarity with words
|
Confusions occur if words sound alike
But not for similar meaning And not for similar looking |
|
|
Articulatory suppression and what it does
|
Repeatedly say "the" when viewing the list..won't be able to repeat words to yourself which prevents formation of phonological code by subvocal articulation
Acoustic confusion effect disappears |
|
|
2 limits of phonological loop
|
Time effects due to decay and speed of rehearsal..only 2 seconds to rehearse before fading away
Chunking effect due to the capacity of the store |
|
|
Dual task interference effects
|
If two tasks require the same cognitive
system, they cannot be performed successfully at the same time. § e.g., two tasks that both require the phonological loop § If two tasks require different cognitive systems, they can be performed at the same time § e.g., one task that requires the phonological loop and one t |
|
|
Which one takes the longest on Brook's task
|
Pointing to the yes or no!
|
|
|
PET subtraction: Spatial
Working Memory formula |
PET activation in Memory
- PET activation in Control Brain areas related to Visuospatial sketch-pad |
|
|
3 central executive functions
|
§ Supervise attention
§ Maintain focus on what is relevant § Planning/Coordination § managing goals, subgoals, multiple tasks § switching from one task to another § updating contents of working memory § Monitoring behavior and inhibiting inappropriate action |
|
|
3 things with frontal lobe syndrome
|
§ Distractibility, difficulty concentrating
§ Problems with organization, planning § Perseveration: fail to stop inappropriate behavio |
