You folks could probably answer this question better than anyone else I can think of. Is there any evidence that computer spell checkers help improve peoples’ unaided spelling skills? I ask because I believe it has helped mine. The immediate feedback offered as I type on a word processor seems to break any tendency I might have to start spelling certain words wrong all of the time.
No doubt there are educators, psychologists, and others who would argue that a spell checker makes us lazy and without the spell checker on the system we would soon regress to our primitive spelling roots. Maybe they’re right and my improved spelling is just a figment of my imagination, or perhaps a natural tendency that would have happened anyway after many years of writing.
