Learning and Decay of Prediction in Object Manipulation (original) (raw)

This research investigates how predictive responses are developed and decay in object manipulation tasks, specifically focusing on grip force adjustments when objects are handled. Through a series of linked and unlinked trials involving torque motors, findings reveal that anticipatory grip force rapidly develops after linked trials but decays slowly, being influenced by previous experiences rather than the time elapsed. The nature of the object's physical characteristics also dampens prediction mechanisms, highlighting that the learning and decay processes associated with predictive responses are complex and depend significantly on contextual factors.
