The Reggio Emilia exhibit featured children performing a cross-modal exercise of drawing the sounds of various types of shoes walking down stairs to illustrate the "Hundred Languages of Children" concept. It showed how kids translate auditory experiences into visual ones - high heels would been drawn with spikey patterns and construction boots would be big wavey ones. This is reminiscent of the Bouba-Kiki effect. But other smaller nuances such as duration translating to span and loudness to magnitude.

I took away a fascinating insight from childhood cognition: children effortlessly bridge sensory modalities, an ability that often diminishes in adults to the point that asking an adult to “draw this sound” or “build something that feels like this smell” is met with a blank look but which a child is often completely game to try. Tasking an adult with a cross-modal assignment literally does not compute.

This cross-modal perception revealed that children possess a remarkable synesthetic intuition, using diverse forms of expression to understand and interpret the world—an ability I had completely forgotten as an adult, which hindered my communication with young children in early education environments.

It highlighted the importance of nurturing cross modal communication styles and once one notices it (like in say Mr. Rogers opening ritual to use multiple queues to engage children’s parasympathetic nervous system) one unlocks a whole new vocabulary with not just children but adults. It’s been a powerful tool in my creative toolbox since.

Does this effect have a name?

The shape with sharp, jagged edges would occur in real life if it were made of some hard material, perhaps, like glass, metal, etc. The shape with the soft, curvy lines would occur if it were made of something softer and possibly elastic.

It doesn't take much intuition to guess that the sharper shape will produce a sound closer to "ki," with sharp transients and lots of high frequencies - like a piece of glass or metal falling - and the rounded one perhaps closer to "bou," with softer transients and perhaps a time-varying resonant frequency as the shape is malleable (think of the sound of a drop of water landing).

Ramachandran and Hubbard suggest that the kiki/bouba effect has implications for the evolution of language, because it suggests that the naming of objects is not completely arbitrary. - Nonsense, mama is an easier syllable for mouths to make, that's the sound that cats make as well as cows.

The cards in the game have nonsense words and illustrations. Players work through various scenarios where they try to agree about which nonsense words should go with which illustrations.

I don't think I'm alone in this: I googled Kepick and Oona and found a reference from a 2012 blogpost: https://nwccapstone.blogspot.com/2012/02/meet-oona-and-kepic...

So I have to ponder how bouba/kiki diverged into kepick/oona. Kinda wonder if some random schoolteacher remembered the study but didn't remember the exact names, substituted something similar, and then built it into a curriculum that got picked up by the education system.

Humans have a psychoacoustic effect that makes higher pitch sounds perceived as being louder.

When somethting has a louder intial sound, but the transient sound is about the same, it makes it feel more snappy (like a snare, versus a kick). This is reminiscent of a jagged edge.

I am curious about something with German, and would love feedback from native German speakers: “gendering” on German words seems to be largely arbitrary (as opposed to the romantic languages where gendering seems to align with how the culture associates the word to a gender). My suspicion, that has “felt” correct in most cases, is that gendering in German words is largely an artifact of which article sounds the most correct with the word. Sort of how we might use “a/an” with words that have consonant or vowel starting sounds in English.

Is there any truth to this supposition?

Strangely, everyone I've asked says they would want to be Bouba. No one wants to be Kiki.

Kuchi <> Kiki Banthu <> Bouba

It would be pretty mind-blowing if it still worked.
