Experimental runs from two participants. The first participant started both run #1 (solid black line) and run #2 at 1 semitone (ST, dotted black line). The second participant started run #1 at 1 ST (solid blue line) and started run #2 at 0.5 ST (dotted blue line). Red arrows indicate the last four reversals that were calculated for the just-noticeable-difference (JND) for participant #1, run #1.
