Our senses have a powerful influence over how we behave or respond to different experiences, with a fragrance evoking particular feelings or memories of a past event. A research team led by Kaori Tamura based at Kyushu University, Japan, have shown for the first time that citrus fragrance can disrupt visual memories associated with orange colour. Although previous studies have reported how individuals perceive odour is personal because of their genetic makeup and cultural background, the results of this research experiment showed citrus like odours can disrupt memories associated with orange colour. The interesting finding leaves the way open for future studies to investigate the effects of different fragrances on other colour related memories.

The research article Olfactory modulation of colour working memory: How does citrus-like smell influence the memory of orange colour? is freely available in the journal PLoS ONE.
