Experiment 2
Experiment 2 was designed to probe feedback responses to unexpected force fields and investigate possible differences in participants’ ability to adapt the feedback response of an ongoing movement (Evolution of extracted parameters in the null field trials in experiment 2. To assess the influence of force field trials on the control strategy in more detail, we measured the change in MS on the trials immediately following a force field trial (Looking at the adaptation to the randomly interleaved force field trials, participants showed an adaptation across trials as shown by an increase in the correlation between the force applied by the robot and the force produced by the participant (Outputs of the force field trials of experiment 2.
