Localisation of aspects of language
Aim – To demonstrate different levels of activity in the brain resulting from different types of language.
Method– A specialised scanner was used to measure different levels of brain activity in the left hemisphere of the cerebral cortex. Participants were asked, on three separate occasions, to (a) listen passively to a list of nouns on a tape recorder; (b) think of verbs to attach to a noun (e.g. to ‘eat a cake’); and (c) silently read the list of nouns.
Conclusion– The scan demonstrates that certain areas of the brain are involved with different aspects of language. The brain scans also showed that other areas of the brain were involved, especially when people were asked to link nouns and verbs together.
