A language pathologist from Sweden, Ingrid Behrn, has found that computerized writing aids can improve writing ability in people with aphasia, a condition that can arise after a stroke.
People with aphasia experience a reduced ability to use and understand spoken and/or written language. Ingrid, in her studies, found that spell-check programs combined with word prediction allow subjects to write longer sentences and make fewer mistakes. This is very promising because it could help them better express themselves.
Good news for sufferers of Aphasia; and just earlier today we saw an iPhone app that helps relieve stuttering. Nice to see this kind of beneficial effect from technology.
