The results of the study are shown in Table 1.

Table 1 The number of objects participants correctly recalled in each group

Calculate the ratio of the total number of objects correctly recalled in Group A compared to Group B.

Write this ratio in its simplest form.

One factor that can affect the accuracy of memory is context.

Which two of the following are most likely to occur due to context?

Shade two boxes.

Which of the following is the correct definition of a ‘false memory’?

Shade one box.

A researcher wanted to investigate the effect of context on the accuracy of memory.

Describe how she could design a laboratory experiment to do this.

You need to include the following information in your answer:

• a task that she could ask participants to carry out and a description of the data she would collect

• what the conditions of the independent variable would be

• one extraneous variable that could affect the results and how the researcher could control this variable.

The researcher considered different experimental designs when planning her experiment.
