There are terms for the rolling sound of thunder (goro goro, ごろごろ), the flickering light off a pond (kira kira, きらきら) and the slippery but firm feeling of a fish’s scales (tsuru tsuru, つるつる). Japanese is one that is rich in sensory vocabulary, McCormick said. It sounds like what it means.”ĭifferent languages vary in how the sounds of words convey meaning. In her doctoral research at Emory University, Kelly McCormick, a cognitive scientist, asked, “What is the underlying neurological processing for feeling like something is a good match?” She keeps a list of words whose meanings she feels relate to their pronunciation. Studies continue to explore the kiki/bouba effect and what we can learn from it. In a 2014 article in the academic journal Language and Speech, Annette D’Onofrio, an assistant professor of linguistics at Northwestern University, attributed the phenomenon to the shape our mouths make when we say “kiki” and “bouba.” With “bouba,” our lips are rounded and our oral cavity is open whereas our lips become tight and constrained when we pronounce “kiki.” When spoken aloud, the word “kiki” uses more energy, as seen in spectrograms. Why so many of us are in agreement on these words isn’t entirely clear, but there are some theories.
