Working Memory Flashcards
1
Q
Working Memory
A
- Limited-capacity system for temporary storage & manipulation of info for comprehension, problem-solving, learning, reasoning, etc.
2
Q
WM-Corporate analogy
A
- Head honcho in charge of info processing = Central Executive
- Controls attention; dividing attention b/t tasks
- Manipulating info for tasks
- Manipulating info for tasks
- Retrieval from LTM
3
Q
Rehearsal Buffers
A
- Phonological Loop
- Visuo-spatial sketchpad
- Keep info around for current tasks
4
Q
Central Executive
A
- Central executive coordinates processing: Focuses on specific parts of a task & switches attention from one part to another
- Deep CE processing leads to transfer to LTM
- assisted by 2 rehearsal buffers
5
Q
Baddeley’s Revised WM Model
A
- Episodic Buffer: Storage system that can integrate info from different modalities.
6
Q
Phonological Loop
A
- aka phonological store, storage unit, “inner ear”
7
Q
Articulatory Loop
A
Articulatory loop: maintenance rehearsal (process)
sound-based, subvocal repetition -“inner voice”
Supporting Evidence:
- Phonological similarity effects
- Word length effects
- Articulatory suppression effects
8
Q
Phonological Similarity Effect Task
A
- remember the following letters; 8s delay; recall
- Memory is poorer when Ps rehearse a set of items that sound similar vs. not
- g c b t v p
- o l k s y g
- Intrusion errors during retrieval:
- Often phonologically similar to TBR words
- Rarely similar in meaning
9
Q
Phonological Word Length Effect
A
- Try to remember the following words; 8s delay; recall
- IV= word length (4-5 letters vs 7-8 letters)
- # of symballs seems to be more important than number of letters
10
Q
Articulatory Suppression Task
A
- Try to remember the following words; 8s delay; (1/2 of Ps read “THE” out loud); recall
- poorer recall with a suppression
- other sound info disrupts rehearsal of TBR info
