We post often about synaesthesia, a strange neurological condition characterized by a link between two or more senses. (A particular musical note "sounds" red, etc.) New research suggests that many more people may have synaesthesia than realize it. In one experiment at McMaster University in Canada, self-described non-synaesthetes associated the smell of certain foods with certain colors and textures. From New Scientist:
When the researchers analysed the results, along with some obvious associations – lemon with yellow and peppermint with smooth, hard and sticky – they found some odd ones.
Do we all have some synaesthetic ability?
Significantly more people than chance, for instance, associated the smell of mushrooms with the colours blue or yellow. Lavender elicited the colour green and the texture of sticky liquid, while ginger was perceived as black and sharp.
"The influence of learning is there," (researcher Ferrinne) Spector told a meeting of the American Synesthesia Association in Hamilton on 27 September, "but it cannot explain all associations."

In a blog post, spokesman Matthias Rose says that it’s had a good 20-year run and is obsolete. But it’s also true that the decoding patents expired last year, […]
Freddy deBoer writes that he’s been telling the same joke for years about Silicon Valley’s only product, which might be universalized as “At last, a way to verb with nouns on the internet!” But the social-media techopoly is stable, now, and so the venture capitalists have moved on to the three terrible trends that will […]
As the old saying goes, “You should sit in meditation for 30 minutes every day. Unless you are too busy, in which case you should meditate for an hour.” Since most of us have an endless list of things to do and people to see, carving out quiet time can feel impossible, especially when most […]
