Outline of Final Research Achievements

This study investigated how the information of force and displacement is used to perceive the elasticity. Pressing strength was adjusted for object stiffness, where objects were pressed more strongly if objects were harder or the stiffness difference between compared objects was small. Besides, the pressing forces applied to two compared objects approached the same magnitude with increasing object stiffness. Further, the type of perceived kinesthetic information used to discriminate between objects also changed along with stiffness range, corroborating the changes of motor control. Differences in force were most easily perceived at lower stiffness ranges, while displacement differences were perceived more readily at higher stiffness ranges.
