Title

The Effects Of Handedness And Dominance On Motor Task Performance

Abstract

Two studies were carried out to examine the effects of user handedness and hand dominance on a motor task using Fitts' law. Study one was designed to validate our previous findings showing differences between leftand right-handed participants who completed a mouse-pointing task using Fitts' law. Results showed that right-handed participants were significantly faster than their left-handed peers, thereby validating our previous findings. Study two examined the effect of handedness and hand dominance on motor task performance by requiring two groups of left- and right-handed participants perform the motor task using both their dominant and non-dominant hands. Results showed a significant interaction between handedness and hand dominance on task performance. Right-handed participants were again significantly faster than their left-handed peers when both groups were using their dominant hand. However, left-handed participants were significantly faster than their right-handed peers when both groups were using their non-dominant hand. These findings might be attributed to prior training with computer mice designs that do not account for user handedness. Both theoretical and practical implications, as well as directions for future studies are also discussed.
