We've all heard stories about adults with synesthesia, their senses intermingled in a way that allows them to taste orange, see an E-flat and hear the music of a delicious glass of juice. It's supposedly what gives such self-professed synesthetic musicians as Richard D. James (AKA Aphex Twin) their edge.
But what if I told you that all babies are little Aphex Twins, and not in a creepy way?
Yes, according to a 2011 study published in Psychological Science, we come into this world with our senses so joined that stimulating just one of them reliably stimulates the others. They're essentially tripping at all times.
