The relation between mental rotation and handedness is a consequence of how handedness is measured.

This study investigates the mental rotation performance of right- and left-handers on a chronometric mental rotation task. Hand preference as well as different types of hand performance were measured. Previous studies have reported slightly better mental rotation performance in right-handers compared with left-handers. However, different forms of hand performance were not considered in these studies. In this research, 61 participants completed a chronometric mental rotation task with cube figures. Handedness was measured using the Edinburgh Handedness Inventory, finger tapping, grip strength and the Grooved Pegboard Test. Our results showed that right-handers do not generally show faster reaction times than left-handers on mental rotation tasks, when handedness is measured using a typical handedness questionnaire. However, using a handedness measure of visuo-motor control and manipulation skill, we found that individuals who solved the task faster with their right hand significantly outperformed participants who solved the same test faster with their left hand.
