Assignment accuracy as a function of the number of subjects.

<p>The assignment accuracy was examined within the data collected in the main experiment using N = 1, 2, 3, … 16 subjects as reference. The assignment accuracy was 33.46% (chance = 06.25%, solid black line) when all 16 subjects were used as reference. The shaded area represents the standard deviation of assignment accuracies observed with repeated assignments (i.e. across the assignments generated with all unique combinations of subjects drawn from the sample of 16).
