Unit 1: Memory Theory

Question 1

The Atkinson Shiffrin Model

Answer 1

• 3 zones of memory
• how info is transferred
• 3 ways to compare/contrast memory modes

Question 2

Sensory store

Answer 2

• “loading dock”
• buys brain time to store it before doing something with it
• most info does not pass this zone
• Atkinson Shiffrin model

Question 3

Short term memory(stm)

Answer 3

• what you’re thinking about right now

- Atkinson Shiffrin model

Question 4

Long term memory (Ltm)

Answer 4

• childhood
• “safe of memories stored”
• very fast
• importance

Question 5

Attention (transfer)

Answer 5

-info gets transferred from sensory store because the brain may pay attention to it

Sensory store➡️STM

Question 6

Maintenance rehearsal(transfer)

Answer 6

-keep info in STM long enough to complete a task

STM⬅️Maintence rehearsal

Question 7

Active rehearsal

Answer 7

-using tools to help keep info into LTM

STM➡️LTM

Question 8

Retrieval

Answer 8

-transfer back and forth from STM to LTM to remember

STM⬅️LTM

Question 9

Decay time

Answer 9

• how long will info stay before it disappears
• Aspects of the model
• sensory store: 1 sec
• STM: 20-40 secs (unless rehearsed)
• LTM: unlimited

Question 10

Storage capacity

Answer 10

• how much room in memory before it’s clogged
• Sensory time: unlimited
• STM: 5-9 chunks
• LTM: unlimited
• Aspects of the model

Question 11

Encoding mode

Answer 11

• how info is organized in memory
• Sensory store:random
• STM: acoustic
• LTM:Semantic
• Aspects of the model
