Throughout history, each of our senses has been crucial to our survival, enjoyment and evolution.
Our senses work together to paint a picture of the world around us. They help to identify the difference between what is dangerous, what is nourishing, what is joyful and what is necessary for our growth. Working together, the senses deliver important messages to our brains that directly dictate what we do and how we feel.
Crossmodal perception is when two or more senses interact with each other, creating a deeper, richer and all-encompassing experience like synesthesia.
Two researchers, Daniel Wesson and Donald Wilson, noted that this unique experience could have had an evolutionary purpose – the combination of an unfamiliar odour and the sound of movement could have alerted us to a nearby predator.
Now, though, with predators no longer our primary concern, we can combine sound and scent in a much more positive and lighthearted way to bring joy to our everyday lives.
