A BBC News article reveals research done by UK scientists that suggests language may not be necessary for intelligence, particularly mathematical reasoning. Rosemary Varley and other researchers at the University of Sheffield department of Human Communication Sciences discovered that patients suffering from severe aphasia who had lost the ability to understand or produce syntactic language, were still able to solve mathematical problems. The new study contradicts prior studies in which subjects used an area of the left frontal lobe associated with language understanding to solve math problems. Researchers now suggest we look for signs of mathematical reasoning in other animals. A paper about this research, titled "Agrammatic but numerate", will be published in an upcoming issue of the Proceedings of the National Academy of Sciences.
