Practice question · True or false
Language is left-lateralised in about 95 per cent of right-handers.
Hints
- The figure comes from Wada testing and is corroborated by imaging.
- It is around 95 per cent, against roughly 70 per cent for left-handers.
Show the answer
True
Why
True, and the left-handed figure of roughly 70 per cent is the useful companion. Left-handedness shifts the probability without reversing it, which is why handedness alone is a poor guide to an individual patient and the Wada test was used before surgery.
