Blind People process touch faster:
Neuroscience research has indicated that blind people can process touch faster than people who have normal vision. "Study suggests brain may adapt to vision loss by increasing speed of tactile perception."
Daniel Goldreich, PhD, of McMaster University explored whether people
who have a special reliance on a particular sense,in the way blind
people rely on touch, would process that sense faster:
"Our findings reveal that one way the brain adapts to the absence of
vision is to accelerate the sense of touch,” Goldreich said. “The
ability to quickly process non-visual information probably enhances the
quality of life of blind individuals who rely to an extraordinary degree
on the non-visual senses.”
Early onset on blindness can sense touch even faster"
The authors tested the tactile skills of 89 people with sight and 57
people with various levels of vision loss. The volunteers were asked to
discern the movements of a small probe that was tapped against the tips
of their index fingers. Both groups performed the same on simple tasks,
such as distinguishing small taps versus stronger taps. But when a small
tap was followed almost instantly by a larger and longer-lasting
vibration, the vibration interfered with most participants’ ability to
detect the tap, a phenomenon called masking. However, the 22 people who
had been blind since birth performed better than both people with vision
and people who had become blind later in life.
