In two experiments, the hemispheric asymmetry for a haptic perception of length was investigated. As stimulus, thin sticks were pasted on the wooden board with some intervals. In both experiments, after the learning the criterion length, the participants were asked to trace and report the length of the intervals between the sticks. In experiment 1, participants were instructed to report the length by moving their left or right index finger, freely. In experiment 2, they were instructed to report the length by moving their finger joint or their elbow joint, respectively. In the results, there was significant left hand (right hemisphere) advantage for the under 5 cm length condition in both experiments. There was no difference between the moving joints used for the judgements. The right hemisphere advantage for metric perception of the visual and haptic information was discussed.
