Topic: constrained grasping

Dexterous object manipulation with the freedom of choice of contact points has primarily been shown to elicit a feedback-dependent force control as opposed to the classically studied memory representation-based force control for constrained grasping. We probed this dichotomy in sensorimotor integration by introducing uncertainty about the grasp type during movement preparation within the context of motor planning. An inverted T-shaped instrumented manipulandum was presented to 24 participants, and they were asked to reach, grasp, and lift it while minimising the peak roll. On certain catch tri
