You have been asked to investigate the effect of emotion on perception.

Explain how you would design an experiment to do this.

You need to include the following information in your answer:

• what you would ask the participants to do and what data you would collect

• the experimental design you would choose and why this would be suitable

• the results you would expect to find from your experiment including both conditions of the independent variable.

Read the following article.

Table 1 shows the frequency of reported temperature scores for Condition A. One of the scores is missing.

Name the type of data that is shown in Table 1.

Calculate the number of participants who reported a temperature score between 6 and 10.

Show your workings.

Sketch a histogram to show the results in Table 1.

Include the number of participants you wrote in answer to Question 10.2.

Provide a suitable title and labels for your histogram.

The researcher found that participants in Condition B reported the water felt warmer than participants in Condition A.

Using your knowledge of ‘perceptual set’, outline one conclusion that the researcher could make from these findings.

Read the following information.

A teacher carried out an experiment to investigate factors that can affect perception. She divided her class into two groups: A and B. Group A was shown nine different pictures of rabbits. Group B was shown nine different pictures of ducks.

Both groups were then shown Figure 1 and were asked what animal they saw.

The results are shown in Table 1.

Use your knowledge of one factor that affects perception to explain the results shown in Table 1 (on page 10).

Outline how culture can affect perception. Refer to both Marc and José’s comments in your answer.

A researcher studied the effects of emotion on perception.

Two weeks before Christmas, he asked a group of children to each draw a picture of a Christmas tree with presents under it.

Two weeks after Christmas, he asked the same children to each draw a Christmas tree with presents under it.

He counted the number of presents that the children drew before and after Christmas.

Table 1 shows the mean number of presents drawn by children before and after Christmas.

Identify the type of data that is shown in Table 1 and explain your answer.
