Memory

Question 1

Define capacity

Answer 1

Amount/ quantity-the quantity of information stored

Question 2

Define duration

Answer 2

Time - the length of time information is held for

Question 3

Define coding

Answer 3

Format - the type or format of information being stored

Question 4

What is the multi-store model of memory?

Answer 4

A linear model suggesting that all memory stores are separate and unitary
Was proposed by Atkinson and shiffrin (1986)

Question 5

Describe the sensory register

Answer 5

Capacity - very large
Duration - very brief (milliseconds)
Coding - sense specific

Question 6

Describe short term memory

Answer 6

Capacity - 5-9 chunks of information
Duration - 18-30 seconds
Coding - acoustic format

Question 7

Describe long term memory

Answer 7

Capacity - unlimited
Duration - lifetime
Coding - semantically (by meaning)

Question 8

Describe the multi-store model of memory

Answer 8

• is a linear model suggesting that all memory stores are separate and unitary - information enters sensory register, has a large capacity but very brief duration (milliseconds), is coded sense specific
• if we pay attention this information enters STM, capacity of 5-9 pieces of information, duration of 18-30 secs and is coded acoustically
• transferred to LTM, has unlimited capacity, lifetime duration, coded semantically
• information may be recalled from LTM into STM for easy retrieval

Question 9

Describe the procedure in the study for coding in STM and LTM

Answer 9

Baddeley
Procedure
Gave different list of words to 4 groups of participants to remember
Group 1- acoustically similar (hat,cat)
Group 2- acoustically dissimilar
Group 3- semantically similar (big,huge)
Group 4- semantically dissimilar
Participants were shown original words and asked to recall them in certain order
