BIOGRAPHY

| "I'm fascinated by the fact that we live in a time when so many people are doing fantastic work, and thinking in areas which it's not remotely possible for me to keep up with & and these people are prepared to talk about it. They're prepared to come on In Our Time and other programmes on Radio 4 and try and talk to the rest of us ..." |

PERCEPTION AND THE SENSES

Use our research page to find our more about this subject.
Barry Stein's laboratory at Wake Forest University in the United States found that the shape of a right angle drawn on the hand of a chimpanzee starts the visual part of the brain working, even when the shape has not been seen. It has also been discovered that babies learn by touch before they can properly make sense of visual data, and that the senses of smell and taste chemically combine to give us flavour.
Perception is a tangled web of processes and so much of what we see, hear and touch is determined by our own expectations that it raises the question of whether we ever truly perceive what others do.
What governs our perception of the world? And are we correct to distinguish between sight, sound, smell, touch and taste when they appear to influence each other so very much?
