Molyneux proposed a scenario where a person blind from birth learns to distinguish a cube from a sphere by touch. Would they then be able to recognise these shapes visually upon gaining sight? Studying this question in humans is ethically challenging. However, Dr Versace and her team used chicks, which hatch with well-developed sensory systems.
Remarkably, when exposed to light for the first time, chicks that had touched a smooth object preferentially approached the visual representation of a smooth object, and vice versa. This suggests that chicks can inherently link touch with sight, even without any prior visual experience. This breakthrough opens exciting new avenues in understanding how our brains process information across different senses. It could also lead to a deeper understanding of how our senses develop and interact with the world around us.Researchers have made an important discovery about the way our brains process the sensations of sound and touch.
