Short-term memory (STM) and Long term memory (LTM)

Psychologists have conducted research that has found important differences in the duration,

capacity and encoding of information in STM and LTM.

You need to be able to explain what short-term memory is:

Find the key terms on p.5

Read: Short-term memory

Use the information to answer the following question:

Explain what is meant by short-term memory (STM). (2 marks)

You need to be able to explain what long-term memory is:

Read: Long-term memory

Use the information to answer the following question:

Explain what is meant by long-term memory (LTM). (2 marks)

You need to be able to explain what duration means.

There are important differences in how long a memory lasts in STM and LTM.

Read the ‘Can You....? questions on p.5

A Repeated Measures Experiment

In a repeated measures experiment each participant takes part in all of

the conditions under test.

Peterson and Peterson conducted a repeated measures experiment

to find out how long a memory lasts in short-term memory.

Have a look at the blue table on p.77 ‘Comparing experimental designs’.

You need to know two strengths and two weaknesses of the three main experimental

designs. These tables will help you to do this.

Turn to p. 5Read the box: ‘Design your own study of the duration of short-term

memory’.In pairs you are going to replicate

Peterson and Peterson’s (1959)

repeated measures experiment that

found out how long a memory can last in

STM.
