Capacity - Memory

Question 1

How much information can STM store?

Answer 1

7+ or -2 chunks of information.

Question 2

How much information can LTM store?

Answer 2

Can store unlimited information.

Question 3

What was Jacobs’ aim in his study in Capacity in STM?

Answer 3

Aim was to see how much information can be stored in STM.

Question 4

Explain the process of Jacobs’ study in Capacity in STM.

Answer 4

• He used a serial digital span technique to asses the capacity of the participants memory.
• They were given a series of digits or letter that they were asked to recall.
• Started off with 1 digit or letter and increased as they recalled them.
• Once the recollection fell to 50% or less of correct letters or digits, the participants had reached their capacity.

Question 5

What were the results of Jacobs’ study in Capacity in STM

Answer 5

Found that participants recalled more digits than letters. Digit recollection was 9.3 and letter recollection was at 7.3 so therefore STM has a limited capacity.
