Coding, capacity and duration of memory

Question 1

Coding

Answer 1

Format in which information is stored in various memory stores

Question 2

Capacity

Answer 2

Amount of info that can be held in memory store

Question 3

Short-term memory

Answer 3

Limited capacity memory store

Question 4

Long-term memory

Answer 4

Permanent memory store- semantic, unlimited capacity, can store memories for a lifetime

Question 5

Research on coding & evaluation

Answer 5

Baddeley- Acoustic in STM, semantic in LTM

Artificial stimuli

Question 6

Jacob’s research on capacity

Answer 6

Digit span- Jacobs 9.3 digits, 7.3 letters

Question 7

Evaluation for capacity

Answer 7

Lacking validity

Not so many chunks- only about 4

Question 8

Research on STM duration

Answer 8

STM- Peterson and Peterson: up to 18 seconds without rehearsal
.

Question 9

Evaluation for duration

Answer 9

Meaningless stimuli
Higher external validity
Peterson and peterson may be displacement not decay

Question 10

Duration

Answer 10

Length of time info can be held in memory

Question 11

Research on LTM duration

Answer 11

LTM- Bahrick et al (yearbooks): recognition of faces after 15 years: 90%, recall 60%. Recognition dropped to 70% after 48 years

Question 12

Miller’s research on capacity

Answer 12

Everyday practice- noticed things come in 7’s
Can recall 5 letters as well as 5 numbers
=Chunking

Question 13

The 4 groups for coding research

Answer 13

Acoustically similar
Acoustically dissimilar
Semantically similar
Semantically dissimilar
