Within the research of mirror writing there is a large debate on who is superior at writing in mirror reverse, left or right handed individuals. The most known examples representing either side of the argument are Tankle and Heilman (1983), who claim that left handers are better at mirror writing; and Vaid and Stiles-Davis (1989), who claim that there are no differences between the two handedness groups. This study was conducted in order to finally determine who is superior by examining both left and right handers ability to mirror write, with both their dominant and non-dominant hands. In addition to this we have also examined the participant’s ability to complete a dual task at the same time in order to assess the cognitive load of mirror writing, and have also examined the effect of symmetry of letters on mirror writing ability. Our results showed that left handers were better at mirror writing with their non-dominant hand which does not support Tankle and Heilman’s (1983) claim, however our results also do not support Vaid and Stiles-Davis (1989) as we did not find that left and right handers were exactly the same when mirror writing. Our results also showed that mirror writing has a high cognitive load and asymmetrical letters are the hardest to write in both forward and mirror reverse. In conclusion more research is required to further determine who is superior at mirror writing.
