Figure 2.

Nine velocity prototypes for experiment 1 in (meter per second) and (degree per millisecond), respectively. Each prototype is depicted as star plot containing the four velocity components drawn onto color coded lines equally dividing the drawing plane. For each line the distance of the dot from the center determines the absolute value of the corresponding velocity component, the error bars visualize the SD of this value. Whether the value is positive or negative determines at which part of the line relative to zero point the value is plotted. Percentage of data points assigned to the individual prototypes determines the relative occurrence of each prototype. For detailed description, see text.
