Figure 6.
Effect of previous trial on stiffness (Kyy) produced in the current trial for main study. A, Transitional stiffness difference for all objects, relative to their overall mean, collapsed over all object curvatures. Horizontal axis shows the object curvature on the previous trial, and vertical axis shows how object curvature systematically influences the stiffness on the current trial. B, Stiffness difference for the four objects, relative to their overall mean. Note the difference in scale between A and B (gray area corresponds with scale in A), indicating that the previous trial has a minor influence on the stiffness value of the current trial (∼10%).
