Evidence of the bouba-kiki effect in naïve baby chicks
Summary
Researchers demonstrate evidence of the bouba-kiki effect in naïve baby chicks, suggesting cross-modal sound-shape associations may arise early in development without training. The study extends a perceptual bias previously observed in humans to avian species, indicating shared cognitive strategies for linking auditory and visual cues. These findings have implications for understanding innate perceptual mechanisms and could inform AI perception research and human-animal interaction design.
