If you look at the bouba/kiki effect[0] almost everybody shares this synesthesia-like shape to sound mapping. I'm pretty sure that as the concept of synesthesia is more well-know you'll see many more people report it. Don't have any source for this but I feel like these synesthesia like mappings are pretty fundamental when learning/memorizing. Seems to me like everybody makes these unusual associations that don't seem to follow any obvious logic to memorize things. But not everybody can readily verbalize and describe what they're seeing/feeling. Say when speaking or listening to Chinese I have a visual sensation representing the tonality. Which to me is pretty obviously an adaptive technique that helped me learn. [0] https://en.wikipedia.org/wiki/Bouba/kiki_effect https://en.wikipedia.org/wiki/Bouba/kiki_effect
