Types of Memory

Question 1

What are the 3 types of memory?

Answer 1

Sensory Register
Short-term memory (STM)
Long-term memory (LTM)

Question 2

What is the sensory register?

Answer 2

• Temporarily stores information from our senses
• Unless we pay attention, it disappears quickly through spontaneous decay
• Limited capacity + V limited duration
• Info coded depending on sense - tactile, visual or auditory

Question 3

short-term memory - capacity, duration, coding

Answer 3

limited capacity + limited duration

coding usually acoustic (sound)

Question 4

long-term memory - capacity, duration, coding

Answer 4

unlimited capacity + unlimited duration

coding usually semantic (meaning of the info)

Question 5

What are the different types of LTM?

Answer 5

Episodic memory
Semantic memory
Procedural memory

Question 6

What is episodic memory?

Answer 6

• Stores realistic events with details such as, time, places and feelings
• Declarative

Question 7

What is Semantic memory?

Answer 7

• Stores facts and knowledge, JUST THE FACTS AND KNOWLEDGE

- Declarative

Question 8

What is Procedural memory?

Answer 8

• Stores info on how to do stuff e.g running or swimming

- Not declerative

Question 9

study for sensory register

Answer 9

Sperling (1960) - An investigation of the sensory register:
Method:
- lab experiment
- participants shown grid with three rows or four letters for 50 milliseconds
- participants had to immediately recall either whole grid or randomly chosen row

Results:

• Only managed to recall 4/5 letters on average
• When a particular row was indicated, they could recall an average of 3 items

Conc:
- Participants didn’t know which row would be selected so the whole grid was held In their sensory register. They couldn’t report the whole grid because the trace faded before they finished recall

Question 10

Study for STM

Answer 10

Peterson and Peterson (1959) - The duration of STM

Question 11

Study for LTM

Question 12

Study for different capacity of memory
