The multi store model

Question 1

what is the capacity of STM

Answer 1

7+-2
miller 9 numbers
7 letter (chunking improves)

Question 2

who discovered capacity stm?

Answer 2

jacob

Question 3

experiment for Capacity stm is

Answer 3

writing down sequences with the amount of numbers increasing
e.g. 4153, 41528 etc

Question 4

what is the duration STM

Answer 4

less than 18 sec

Question 5

who found duration of STM

Answer 5

Peaterson + Peaterson

Question 6

what is the experiment for duration stm
+ finidngs

Answer 6

trigram GKI684
count from 6…5…4…
from 8..7…
till 18
recall trigram
* found: 80%=3 sec
20%=9 sec
2%=18 sec

Question 7

encoding of stm

Answer 7

acustic

Question 8

who found encoding of stm

Answer 8

Baddeley

Question 9

experiment for encoding

Answer 9

4 listis
acustically similar + disimilar
semantically similar + disimilar
AS=10% brain is interested
AD=82%
SS=65%
SD=71%

Question 10

what is the Capacity of LTM

Answer 10

unlimited
lifetime

Question 11

what is the duration of LTM

Answer 11

lifetime

Question 12

who found duration of LTM

Answer 12

Bahrick

Question 13

experiment for duration LTM

Answer 13

400 ppl
classmates
1. with: 15y after=90%
48y= 70%
2. w/o: 15y=60%
48y=30%

accesebility becomes harder

Question 14

how LTM encodes?

Answer 14

semantically

Question 15

who found encodig for LTM

Answer 15

Baddeley

Question 16

how encoding for LTM was found

Answer 16

slides of 10 relevant words for 3 sec
interferences test = hearing and writing 8 numbers 3 times
recaling words from slides in order in 20 min
semantically sim = more interesting, no problem retreiving acoustic sim words

Question 17

who came up with MSM?

Answer 17

Atkinson and Shiffrin 1968

Question 18

describe MSM

Answer 18

ensory info->sensory register->attention->STM(maintenace rehersal)(I>displacment)->repetition<-retrieval->LTM (I> decay)

Question 19

what is the Key study?

Answer 19

Mardock: the serial position curve
Primacy effect=remmeber begining of the list as w r repeating them- transfering to ltm
Recency effect=within the duration and capacity of stm
middle of the list=displaced
supporting the concept of rehesal being necessary to transfer things to ltm

Question 20

eval 1 TOP

Answer 20

sooprt from KF case study

Question 21

eval 1 point

kf

Answer 21

accident
reduced capacity of stm = 1-2 digits
yet his LTM was normall
meaning it is sepaprate stores

Question 22

eval 1 tail

kf

Answer 22

however, the deficit was onlt for verbal info, visual stm and acoustic was normall
This chalanges the msm = there are sub stores
too simplistic

Question 23

eval 1 double

Answer 23

research whows that stm is divided into dif substores, which are not only duration capacity etc,
but the kind of memory
same for ltm : rehersal explains semantic ltm, but doesnt explain episodic tm

Question 24

eval 2 top

Answer 24

another case study that supports MSM

Question 25

eval 2 point

HM

Answer 25

H.M. patient
had hippocumpus removed from both sides
to stop his severe suffering of epilepsy
after operation he could not form any tm memories
but he could remember ltm that was before operation

Question 26

eval 2 tail

HM

Answer 26

supporting msm
as stm and ltm are in dif locations
therefore his previos ltm wasnt damagaged, but the reason why he couldnt form new ltm is because his stm was damaged therefore he couldnt form new ltm

Question 27

eval 3 top

Answer 27

questioning how separate ltm and stm and does actually stm comes first before ltm

Question 28

eval 3 point

separation of stm and ltm?

Answer 28

Logie 1999= stm relies on ltm.
‘AQABBCITC’ - to chunk them you need to recall meaningful groups of letters and these meaning dont come from stm. they come from ltm.
Ruchin= asking ppts to recall aactual words VS pseudo-words. more brain activity for normal words, showung involvment of other areas not just stm

Question 29

eval 3 tail

separation of stm and ltm?

Answer 29

showing stm is hust a part of ltm
not a separate store
