A cognitive psychologist conducts an experiment to investigate the effect of ambient olfactory cues on semantic retrieval speed.
One group of participants performs a category-generation task (listing as many unique animal species as possible in a 2-minute limit) in a laboratory room diffused with natural peppermint essential oil.
The other group performs the exact same category-generation task in an identical room with no diffused scent (normal room air).
State the fully operationalised independent variable (IV) and the fully operationalised dependent variable (DV) for this investigation.
