Lexical-motor synesthesia

ES EN

Very few cases have been documented of this type of synesthesia, which involves involuntary, consistent associations of certain body movements with words as they are heard or thought of.

The first reference to the phenomenon – and the only published study so far – dates back to 1966, when ethnologist and psychoanalyst George (or Georges) Devereux wrote about the case of a young Hungarian who had been a friend of his during their teenage years. The boy had the habit of striking poses or making very specific movements each time he heard certain proper names: the name “Jenö”, for example, prompted him to move his foot as if he was pressing down a pedal or stepping on someone else’s foot. Devereux questioned him extensively on this rather odd behaviour and found that there tended to be a conceptual relationship between the movements and the names, corresponding to an action that he had often actually or potentially carried out with someone who went by that name in his early childhood. The name of his doctor, for example, was connected to the movement of tilting his head back as if to receive a spoonful of medicine. Devereux used the term “audio-motor” to refer to the new type of synesthesia he had discovered.

Recently reported cases of lexical-motor synesthesia

In recent months I had the interesting opportunity to chat online with someone who experiences the same phenomenon as Devereux’s friend. The whole conversation can be read here. This is a short excerpt:


“Some/most words for me are strongly associated with certain actions or movements - I am almost always semi-consiously seeing abstract actions for words in my mind, ie: as I type the word "word", the movement associated my fingers gently touching my lips (semi-parted) and then reaching out. I get this very strongly for proper nouns/personal names and not very strongly/not at all for more verbs, but most words have an action attached which rarely if ever changes. (...)

Also, the actions in my mind are entirely abstracted, so I can't always express the action with my body accurately if I wanted to. (...)

A lot of the actions also make logical sense (like "word") but some really don't (like "Eliot") (...)
The spelling of word changes the action too, if I am reading it. The same word with two spellings have slightly different but very similar movements. (...)
o
The actions do tend to make logical sense - socks and Sonya (similar-ish words) are very similar up pulling actions, but the 'ng' sound in Sonya makes it more of a flexing action (ng can also make words more of scrunching action or a downwards action depending on context).

Here’s another case showing similarities with the two previous ones:

Basically every word has a moving image of a dancing body that I see in my mind. Depending on the word it shows a different part of the body (some are just hands or legs, or entire body). The movements don’t last long, it is just very short moving image for each word. The images for each word have been consistent as long as I can remember, and the images are very specific. Like if I try to imitate them they don’t come across quite right. Sometimes it’s hard to read because the moving images kind of take over.

I have no control over it, and the more I focus on the individual word the images get more vivid. I love acting out the body movement for each word. As a kid I loved to go swimming bc some words matching body movement (ones that involve leg movement) was easier to do weightless.

These cases remind me of some I included on my page about “figurative images as a synesthetic concurrent” under the heading “proper names-images/actions”, such as this one (although the lady in question doesn’t seem to feel driven to actually imitate the actions she perceives):


My husband’s name is Travis,  and when I hear his name I get simultaneous images of a seatbelt being buckled up and a slice of American cheese being unwrapped.”
