Figure 3. Statistical independence of movements.

Figure 3

The probability of hitting the second target given that the first target was missed Inline graphic was plotted against the probability of hitting the second target when the first target was hit Inline graphic. Each point represented a combination of reward and distance conditions from a subject. As most points are distributed symmetrically about the diagonal line, the outcomes of the two movements can be treated as statistically independent. See text.
