Figure 3.
Learning curves of compensatory torque: pregrip and postgrip type switch. A, B, Tcom for two-digit grip trials followed by three-digit grip trials for left and right CM conditions (A, LCM; and B, RCM). C, D, Tcom data from grip type presented in the reverse order (three-digit grip followed by two-digit grip) for LCM (C) and RCM (D). Trials within the dashed box (11–20) indicate the grip type subjects switched to after learning Tcom during consecutive object lifts (trials 1–10) with a different grip type. Data are the averages of all subjects (vertical bars denote SEs).
