• When we hear certain sounds, our brains often pair them with specific shapes. • For example, most people will associate a sharp-sounding word with a jagged, pointed shape, while a soft, rolling word is linked to something smooth and curved. • This fascinating phenomenon is known as the bouba-kiki effect.
Article Summaries:
- A recent study shows that baby chicks, like human adults, link certain sounds to specific shapes-a phenomenon known as the bouba‑kiki effect. Researchers presented chicks with visual shapes and auditory stimuli, finding that the animals consistently paired “sharp” sounds with jagged, pointed shapes and “soft” sounds with smooth, rounded shapes. The results suggest that this cross‑modal correspondence is not unique to humans and may reflect a shared, early‑developed neural mechanism for integrating auditory and visual information. The findings broaden understanding of perceptual organization across species.
