The Influence of Exposure Amount on the Persistence of Short-Term, Haptically Acquired Sensorimotor Memorial Representations

This study investigates the influence that the amount of exposure has on the persistence of sensorimotor memories. Participants acquired memories of an unexpectedly heavy object in one of four groups that varied in the number lifts of the object they each performed. All participants followed this acquisition period with retention lifts immediately and after 2-second and 10-second intervals, as well as after 15 minutes and 24 hours. Grasp force …
