Answer 3

Jacobs

Question 4

Who researched the duration of the STM?

Answer 4

Peterson and Peterson

Question 5

Who researched the coding of the STM?

Answer 5

Baddeley

Question 6

How do you research the capacity of the sensory register?

Answer 6

Flashing a 3x4 grid of letters on a screen and the participants recall one row.

Question 7

Who researched the capacity of the sensory register?

Answer 7

Sperling

Question 8

What was the findings of Spelings experiment?

Answer 8

The capacity of the sensory register is quite large

Question 9

What were the findings of Walsh and Thompson’s experiment?

Answer 9

The iconic store has an average duration of 500 milliseconds which decreases as you get older

Question 10

What was the conclusion of Walsh and Thompson’s experiment?

Answer 10

The duration of the sensory memories is limited and dependant on age

Question 11

What did Crowder find out in his experiment?

Answer 11

The sensory register retains information for a few seconds in the iconic store but for two or three seconds in the echoic store

Question 12

What was the conclusion of the experiment done by Crowder?

Answer 12

The sensory information is coded into different sensory stores

Question 13

Who researched the capacity of long term memory?

Answer 13

Anokhin

Question 14

Who researched the duration of long term memory?

Answer 14

Bahrick

Question 15

Who researched the coding of long term memory?

Answer 15

Baddeley

Question 16

What method did Jacobs use to research short term memory?

Answer 16

The digit span technique. This is when participants repeat a string of digits that get longer each time

Question 17

What was Jacobs findings?

Answer 17

People could recall and average of 5-9 digits

Question 18

What was the conclusion to Jacobs experiment?

Answer 18

The short term memory has a limited capacity and the new information is displaced by the old

Question 19

What method did Peterson and Peterson use to research the duration of short term memory?

Answer 19

The participants were given a trigram of three constants. They had to count back in threes from a large number and then they had to recall the trigram in three second intervals

Question 20

What did Peterson and Peterson find out from their experiment?

Answer 20

As the time interval increased less participants recalled the correct trigram

Question 21

What did Peterson and Peterson conclude?

Answer 21

The information in our short term memory is easily lost if we do by rehearse it

Question 22

How did Baddeley research the coding of short term memory?

Answer 22

He gave them two list of words. One was acoustically similar and one was acoustically dissimilar.

Question 23

What did Baddeley find out in his experiment into short term memory?

Answer 23

Participants that has acoustically similar words performed worse than participants with acoustically dissimilar words

Question 24

What did Baddeley conclude about short term memory?

Answer 24

Short term memory is coded acoustically

Question 25

What did Anokhin find out about the capacity of long term memory?

Answer 25

The number of possible neuronal connections in the human brain is 1 followed by 10.5 million km of noughts

Question 26

What did Anonkin conclude?

Answer 26

No human that exists can use all of their potential brain capacity therefore long term memory is unlimited

Question 27

What method did Bahrick use to research the duration of long term memory?

Answer 27

He gave 400 participants aged 17 to 74 a free recall test, a photo recognition test and a name recognition test

Question 28

What findings did Bahrick receive from his experiment?

Answer 28

After 15 years the recognition was 90% and the free recall was 60%. After 48 years the recognition was 80% and the free recall was 30%

Question 29

What did Bahrick conclude from his experiment?

Answer 29

We can store memory for a life time in the long term memory but we can remember it better when we are given cues

Question 30

What was Baddeleys method for researching coding in the long term memory?

Answer 30

Participants were given a list of semantically similar and a list of words that were semantically dissimilar and they were given a 20 minute interval before recall

Question 31

What did Baddeley find about coding in the long term memory?

Answer 31

The similar meaning words were poorly recalled compared to the words with a distinct meaning

Question 32

What was concluded from Baddeleys experiment about coding in the long term memory?

Answer 32

Long term memory is mainly encoded semantically

Question 33

Which experiments are a lab experiments?

Answer 33

Sperling, Jacobs, Petersons and Petersons, Baddeleys(LTM and STM) and Anokhin

Question 34

Which experiments are not a lab experiment?

Answer 34

Walsh and Thompson, Crowder and Bahrick

Question 35

Which experiment does not need an evaluation?

Answer 35

Anokhin
