Figure 7.

Contextual effects vary with dwell time. A, The mean ± SE force on clamp trials (in direction toward target T1) as a percentage of the force required for estimated complete compensation. Values for all experiments (on the last third of trials during force-field exposure) are plotted as a function of the mean dwell time that subjects used in these conditions, with SE indicated by horizontal error bars. Note that most of the horizontal error bars are so small that they disappear under the symbols. For comparison, the results from the visual static conditions are plotted as a line (shaded region indicates SE) across all dwell times, because they are not related to a particular dwell time. B, The mean ± SE MPE over the last block of trials during force-field exposure. C, The mean ± SE MPE over the first block of trials in the postexposure session in all experiments. D, The mean ± SE peak velocity across all subjects in all experimental conditions experiments (on the last third of trials during force-field exposure), plotted as a function of dwell time.
