Question 1

What is the capacity of short term memory

Answer 1

7 +/- 2

Question 2

What is capacity and how is it represented

Answer 2

A measure of how much can be held in the memory. It is represented in terms of bits of information, such as numbers of digits

Question 3

What is coding

Answer 3

The way information is changed so it can be stored in the memory. Information enters the brain via the senses. It is then stored in various forms, such as visual codes, acoustic codes or semantic codes

Question 4

What is duration

Answer 4

A measure of how long a memory is available before it is no longer available

Question 5

What is the long term memory

Answer 5

Your memory for events that have happened in the past. this lasts from anywhere between 2 minutes to 100 years. LTM has potentially unlimited duration and capacity and tends to be coded semantically

Question 6

What is short term memory

Answer 6

Your memory for immediate events. STM’s are measured in in seconds and minutes rather than hours and days. They will disappear unless they are rehearsed. STM also has a limited capacity of 4 items or chunks and tends to coded acoustically and is sometimes referred to as working memory and lasts around 18 seconds

Question 7

What is semantic coding

Answer 7

Information that is remembered by meaning

Question 8

What is acoustic coding

Answer 8

Information that is remembered by sound

Question 9

What is visual coding

Answer 9

Information that is remembered by images
