US scientists have discovered people who can “hear” what they see.
The rare form of synaesthesia – a condition where senses intermingle – came to light after a student reported “hearing sounds” from a screensaver.
Researchers at the California Institute of Technology then found three more people with the same condition, New Scientist magazine reported.
Those affected performed better in tests of recognising visual patterns than those without the condition. – bbc
