Results of experiment 3. It is shown the second choice correct detection against the detectability estimated from first choice correct detection. It is also shown the predictions of the SDT for both the first and the second choice in the 3AFC experiment. Results of experiment 2 are also plotted and one subject performed two different session of experiment 3, so that 12 points are plotted (5 from experiment 2 and 7 from experiment 3).
