Bouba-Kiki Effect Observed in Naïve Baby Chicks: New Research Insights
New research, published on February 21, 2026, indicates the presence of the bouba-kiki effect in naïve baby chicks. This finding, sourced from Hacker News and available via Science.org, suggests that the phenomenon, typically associated with human perception and language, may have deeper, more fundamental biological roots.

The bouba-kiki effect, a well-documented phenomenon in human psychology where individuals consistently associate rounded shapes with the sound 'bouba' and spiky shapes with the sound 'kiki,' has now reportedly been observed in naïve baby chicks. This intriguing discovery was published on February 21, 2026, and highlighted by Hacker News, with the full scientific article accessible through Science.org. The original news brief itself is concise, stating only 'Comments,' which suggests that the primary information regarding the methodology, results, and implications of this research is contained within the linked scientific journal article. The observation of this effect in a non-human species, particularly in very young animals, could provide valuable insights into the evolutionary origins of cross-modal correspondences and the fundamental mechanisms of perception and cognition. It raises questions about whether the bouba-kiki effect is a learned association or an innate cognitive bias, and how such biases might influence early development and sensory processing across different species.
