Area between Average and Minimum Jerk Curves in XY and Planes. Left: Area between the model curve and the normalized curves for paths in the XY plane. (In order from left to right ND Drink (red), Drink Imagined (blue), Drink Absent (green), ND Feed (red), Feed Imagined (blue), Feed Absent (Green). Average area in the XY plane is 1121.7 mm^2. The object present condition of the drink task produces significantly greater curvature than the other two conditions (p < .0001), which are not significantly different from each other. The feed task shows no significant differences between any of the three conditions. Right: Area between the model curve and the normalized curves for paths in the XZ plane. (In order from left to right ND drink(red), Drink Imagined (blue), Drink Absent (green), ND Feed (red), ND Drink (blue), ND Absent (green). Average area in the XZ plane is 2922.2 mm^2. The object present condition of the reach-to-cup event of the drink task has the greatest area (p < .0001).
