Chewing gum is often thought of as a simple habit, but some researchers suggest it can increase physiological arousal and thereby enhance cognitive performance, such as memory. A psychologist wants to investigate this further by using the experimental method to determine if chewing gum improves short-term word recall compared to not chewing gum.
Explain how you would conduct a study using the experimental method to investigate if people are able to recall words better when chewing gum compared to when not chewing gum. Justify your decisions as part of your explanation. You must refer to:
You should use your own experience of practical activities to inform your response.
