Multi-store model of memory

Question 1

What is the capacity of the Sensory Register?

Answer 1

Unlimited

Question 2

What is the duration of the Sensory Register?

Answer 2

500 milliseconds

Question 3

How does the Sensory Register encode?

Answer 3

Modality-based sensors: Iconic, Echoic and Haptic

Question 4

What is the capacity of the Short Term Memory? Other stuff about the study?

Answer 4

7 + or - 2, Jacobs 1887 Digit Span technique. “Chunking” information makes it easier to recall

Question 5

What is the duration of the Short Term Memory? Other stuff about the study?

Answer 5

Around 18 seconds, Peterson and Peterson. Trigrams were used, filler task given to prevent maintenance rehearsal, time for filler task gradually increased.

Question 6

How does the Short Term Memory encode?

Answer 6

Acoustically, Baddeley 1966

Question 7

What is the capacity of the Long Term Memory?

Answer 7

Unlimited

Question 8

What is the duration of the Long Term Memory?

Answer 8

Indefinite, Bahrick et al

Question 9

How does the Long Term Memory encode?

Answer 9

Semantically, Baddeley 1966

Question 10

What is the name of the model of memory with three boxes, and who came up with it?

Answer 10

Multi-store model, Atkinson + Shiffrin

Question 11

What did Baddeley do? (With encoding of STM)

Answer 11

1966, gave participants 4 lists of words (on paper) then asked for recall immediately. He found that STM encodes acoustically as it was confused when words sounded similar.

Question 12

What did Baddeley do? (With encoding of LTM)

Answer 12

He upped the length of the list to 10 words, and asked for a distractor task to be done 4 times over a course of 20 minutes. Words with similar meanings were recalled the worst, suggesting Semantic recall.

Question 13

Support for the STM and LTM working separately?

Answer 13

Beardsley brain scanning, showed how prefrontal cortex was active during STM, but not LTM
