Models of memory

HideShow resource information
What are the 3 stages of the Multi store memory?
Sensory register, STM, LTM
1 of 17
What is the sensory memory?
Brief storage of sensory information. Duration is around a second but if you pay attention to it it goes into STM
2 of 17
How does the information stay in STM and move to LTM?
Through rehearsal
3 of 17
What research backs the Multi store model?
Baddeley, Bahrick, Peterson & Peterson, HM and Miller as they show that LTM and STM are seperate with different capacities, duration and encoding
4 of 17
What research goes against the Multi store model?
KF- STM is made of 4 different stores, and HM- LTM is made up of 3 seperate stores
5 of 17
What is the case of KF?
He had a bike accident and damaged his verbal memory but still had his visual memory in STM.
6 of 17
What is the Working Memory Model?
More complex description of STM, shows it has 4 parts
7 of 17
What are the 4 parts of Working memory?
Phonological loop, visuo spatial sketchpad, central executive and the episodic buffer
8 of 17
What is the phonological loop and it's 2 parts?
It stores verbal information. Phonological store- retains words & the articulatory control system- rehearse words.
9 of 17
What is the capacity of the phonological loop?
How many words can be said in about 2 seconds.
10 of 17
What is the visuo spatial sketchpad?
Stores visual and spatial information. It has a limited capacity and brief duration
11 of 17
What is the central executive?
It controls and directs, stores some information and retrieves info from the LTM
12 of 17
What is the episodic buffer?
Holds info that is both visual and acoustic with limited capacity
13 of 17
Research for working memory?
Dual task technique, KF, Brain scans
14 of 17
What is the dual task technique?
Baddeley and Hitch give people 2 tasks; 2 lists of words or a list of words & a picture to remember, they found they could remember the different things easier than the same things
15 of 17
Brain scans?
Carter scanned brains and found that when different activities were being done different parts of the brain were active
16 of 17
Against the working memory?
EVR- had a brain tumour and some of his executive skills were damaged and some were ok, showing that the central executive is seperate parts
