What happened
A study led by animal behaviorist Eleonora Biffi at the University of Parma, published in Proceedings of the Royal Society B, tested whether dogs show the bouba/kiki effect. In two near-identical experiments (51 dogs, then 19 dogs whose owners wore headphones playing rock music to block sound cues), dogs watched two screens while 'Bouba' or 'Kiki' played from speakers, and GoPro footage was fed into an AI head-direction tracker as a proxy for gaze. The reported result: dogs looked significantly more at the rounded shape during 'Bouba' and at the spiky shape during 'Kiki', above chance.
Why it matters
For a builder audience this changes no tool, price, or policy - there is no Malaysian or Southeast Asian angle in the text, and nothing here affects what you ship. The one transferable detail is methodological: the team used off-the-shelf GoPro capture plus an AI head-pose model to turn video into a quantitative gaze measure over ~15-minute sessions, which is the same cheap pattern anyone doing behaviour coding or user-session analysis could copy. If you are not doing vision-based measurement, skip this one.
Discussion angle
Worth 60 seconds at most: the study's real engineering content is using an AI head-tracking model as a measurement instrument on 15 minutes of GoPro footage - ask the room whether they'd trust a vision model as the scorer in their own experiments, and what validation they'd demand before believing the 70-dog result.
