Taketa and Uloomu or Bouba and Kiki?

In chapter two we introduced takete and uloomu from John Booth Davies' 1978 landmark book, The Psychology of Music, and the phenomenon in which people across cultures will identify an image with sharp angular lines as takete, and one with curvy lines as uloomu. Fast forward to the present and the currently favored words for the same phenomenon are kik and bouba! It turns out that the origin of taketa goes back to 1947 and Wolfgang Kölher who initially associated the phenomenon with language and language development. New research has show that this phenomenon can be observed even in baby chicks, who, of course, have not developed language proficiency. The abstract from the research suggests "Results from naïve young animals suggest a predisposed mechanism for matching the dimensions of shape and sound, which may be widespread across species."
