The ABCs of Alphabet-Magnet Synesthesia

By Elizabeth Preston | March 27, 2015 8:06 am


Is it cool or existentially disturbing to think that your personal brain quirks might come from the toys you played with as a toddler?

In a study published earlier this month, psychologists asked 6,588 American synesthetes what colors they associate with each letter of the alphabet. Then they compared these associations to a certain vintage set of Fisher-Price alphabet magnets. They found that at least 6% of their synesthetes had improbably close matches to the colors of the magnets.

The researchers defined a statistically unlikely match as anyone with more than 10 letters corresponding to the colors of the toy. At least one person had a 26-for-26 correlation, though. For people born between 1970 and 1985, around when the magnet set was manufactured, more like 15% of synesthetes were Fisher-Price matches.

You can see the whole study for free online, or read more about it at Discover’s D-Brief blog. The psychologists—Nathan Witthoft, Jonathan Winawer, and David Eagleman—stress that no one’s synesthesia (as far as they know) is caused by a toy. Rather, people who are already prone to associating letters with colors may learn those associations from something in their environment.

Longtime Inkfish readers will not be surprised that I gasped in excitement when I saw this paper, because I wrote about a preliminary version of the study (with only 11 subjects) back in January 2013. I was also excited to realize that I’m part of the new data set, since I completed a survey at a shortly afterward.

I am not a Fisher Price six-percenter. But my own internal alphabet does seem like an uncanny match to an old set of Playskool magnets, which my mom kindly dug up and photographed a couple years ago (above). Maybe I’ll see these in the next study?

    I don’t match colors to letters, but I do match colors to numbers, from a perfectly obvious source. Working many years with electronic stuff permanently implanted the resistor color code. No mystery there!

      For some time, I correlated them to CGA/EGA-Colors:
      0x8: bright/blinking
      0x4: red
      0x2: green
      0x1: blue

      So 0xC (12) is bright red, 0x3 is cyan (mixing green + blue).

    Consider the abscissa sequence 1) high correlation, 2) no correlation, 3) high correlation. Do we see two stripes or three? Three! One then desires a second block ordered not by alphabetical abscissa but by correlation abscissa, to reduce Mondrian effects.

    Perhaps the Lüscher Color Test was on to something (else).

  • Tim Fisher

    I think we’re all missing the real question here… WHERE IS THE LETTER C?!

    • 7eggert

      There is always a lost letter. Did you look under the couch or in your pet’s lair?

  • 7eggert

    The obvious question: How were the magnet-letter’s colors chosen? Maybe it was by a (latent) synesthete or by a common association between sounds and letters, and then somebody changed some letters to have a better mix of colors? I guess we’ll never know.

    • Abigail Pine

      That’s a good thought. Were the letters chosen randomly, or were they chosen by a synthetic?

  • Destanie Jones

    I think it is interesting how those who grew up around the time the magnets were manufactured, could relate a color to letters all those years later. Although I can understand that if they saw the letters everyday on the fridge for a few years, that they could memorize and associate colors with specific letters in their adult life. I could imagine it invoking a sense of nostalgia for an adult or they may have just gotten lucky.
