Figure 5.

Mean grasp height (a) in the joint condition and (c) in the individual baseline of Experiment 2 is shown as a function of object weight and participant. In the joint condition, six of 12 participants systematically modulated the height of their grasp as a function of object weight. Grasp height was not modulated in the individual baseline. The object centrally depicted in (a) illustrates where the three colored stripes were located relative to participants’ grasp positions. Error bars show standard deviations. Panel (b) shows mean color choice (in % of trials) per weight and condition across participants. *p < .05, ***p < .001.
