Left-handedness and mirror writingFeatured science projectScience project video


The hypothesis that left handers will be able to perform mirror writing more quickly than right-handers is correct.

Mirror writing was once used as a form of cipher. In modern times, one of the most common forms of mirror writing is seen on the front of ambulances so that drivers in front of the ambulance can read the text in their rear view mirrors. Famous Italian inventor and painter Leonardo da Vinci was known to have kept most of his notes in mirror language.

Also consider

Repeat this science fair project by comparing the ability of ambidextrous persons to mirror-write.

Try to conduct another experiment with emphasis on gender and each gender’s ability to perform mirror writing.

Also, does age have any bearing on a person's ability to mirror-write? Are kids better than adults? Are adults better than retirees? How about the level of education of the participant? Does that have a bearing on your results?
