Short and Long Term Memory

Question 1

STM

Answer 1

memory of immediate events. measured in seconds and minutes rather than hours or days. limited capacity of 4 chunks and coded acoustically

Question 2

LTM

Answer 2

events that have happened in the past. Last anywhere from 2 minutes to 100 years. unlimited duration and coded semantically

Question 3

Capacity

Answer 3

how much data can be stored

Question 4

capacity of STM

Answer 4

assessed using digit span. Joseph Jacobs found average span for digits was 9.3 items and 7.3 letters.

Question 5

magic number 7 + or - 2

Answer 5

George Miller concluded the immediate memory was 7 plus or minus two

Question 6

Duration

Answer 6

how long a memory lasts before it is no longer available

Question 7

duration of STM

Answer 7

STM is short, less than 18 seconds as long as verbal rehearsal is prevented

Question 8

duration of LTM

Answer 8

can potentially last from 2 minutes to 100 years

Question 9

coding

Answer 9

way info is changed so we can store it. Info enters the brain via senses and then stored in various forms such as visual, acoustic or semantic codes

Question 10

Acoustic coding

Answer 10

STM is encoded usually in acoustic

Question 11

Semantic coding

Answer 11

LTM is usually encoded in semantic
