To experience that visual clues influence our perception of odors.
- Peppermint extract
- Banana extract
- Strawberry extract
- Odorless food colorings: red, green, yellow
- Small balls made of absorbent material
- Small transparent plastic cups with a cover
- Prepare three plastic cups: a red one with mint, a green one with banana, a yellow one with strawberry;
- Present a single participant with the three cups mentioning that there is an odor in each cup.
- Ask them to look at the cup and guess which odor it is;
- Let them smell and ask them to guess which odor it is.
Seeing where an odor comes from influences the way we perceive odors and can trick us to think that we are smelling something that we are not.
