Synesthesia: Why some people hear color, taste sounds
Researchers at The Australian National University (ANU) have shed new light on synesthesia — the effect of hearing colors, seeing sounds and other cross-sensory phenomena. Lead Researcher, ANU Research School of Psychology’s Dr Stephanie Goodhew, said the research found synesthetes had much stronger mental associations between related concepts.
Things like hearing shapes, so a triangle will trigger an experience of a sound or a color, or they might have a specific taste sensation when they hear a particular sound,” she said.
“One person reported that smells have certain shapes. For example the smell of fresh air is rectangular, coffee is a bubbly cloud shape and people could smell round or square.”
