Results from the blind tilting task further indicate that it was not haptic information about the glass
diameter that was responsible for superior performance in the manual tilting task. In the blind tilting
task, participants grasped the glasses through an opening in the curtain and, thus, had access to haptic
information about the diameter, but they still did not use this information. Therefore, we conclude
that dynamic sensorimotor information conveyed by the tilting movement, rather than static information
about the diameter, facilitated a mental simulation.
