Multi-store memory model content

Question 1

Atkinson and Shiffrin (1968) aim

Answer 1

Created the first model of memory

Question 2

Atkinson and Shiffrin (1968) model

Answer 2

made up of three distinct (unitary) stores

Question 3

Atkinson and Shiffrin (1968)
memory model explained
(sensory)

Answer 3

• information enters sensory memory
• duration = lost almost instantaneously unless paid attention to
• capacity = a lot of sensory information can be taken in

Question 4

What happens if sensory memory is paid attention to?

Answer 4

it is passed into the STM

Question 5

Atkinson and Shiffrin (1968) memory model explained (Short-Term memory)

Answer 5

• capacity = 7(+/-2) items
• duration avg. is 18 seconds
  but max. is 30 seconds.

Question 6

How is STM encoded into LTM

Answer 6

• acoustically (maintenance rehearsal) = keeps stm present in STM
• semantically (elaborative rehearsal) STM into LTM

Question 7

Atkinson and Shiffrin (1968) memory model explained (Long-Term memory)

Answer 7

• capacity = potentially unlimited
• duration = potentially unlimited

Question 8

How is information lost in Sensory memory?

Answer 8

decay

Question 9

How is information lost in STM?

Answer 9

Decay/ Displacement

Question 10

What is displacement?

Answer 10

Displacement is when the capacity of STM is reached, and other information is lost and replaced or displaced by new information.

Question 11

How is information lost in LTM?

Answer 11

interference

Question 12

What is interference?

Answer 12

when information can be confused during encoding or combined with other information that distorts the memory.
