Question 24

Sweet Scents?

There are many different ambient scents used in aromatherapy that are claimed to influence emotional states. A psychologist wants to use the laboratory experimental method to investigate if exposure to lavender essential oil scent reduces anxiety levels in participants who are completing a challenging cognitive task under time pressure compared to a neutral control condition.

Explain how you would conduct a study using the laboratory experimental method to investigate if exposure to lavender essential oil scent reduces anxiety levels in individuals completing a challenging cognitive task. Justify your decisions as part of your explanation. You must refer to:

  • the experimental design you would use
  • how you would operationalise the dependent variable (DV) in a way that would produce quantitative data
  • one ethical consideration you would take into account.

You should use your own experience of practical activities to inform your response.
