Figure 2.

An example of learning streak trials and a test trial. On the left, the distractor distribution and the target orientation is shown for a learning streak. The distractor orientations are sampled from the same distribution throughout the learning trials, however, the target orientation is randomly chosen given that it is at least 60° away from the distractor distribution mean. On the test trial, the target orientation is chosen to yield different CT–PD values. In the example shown here, the distance between the current target orientation (80°) and the previous distractor distribution mean (60°) yields a CT–PD value of +20°.
