Figure 3
Average response frequencies (black dots) and curve fitting results (black line) for a representative subject. For log scaling factors smaller than 0, avatar movements were reduced. For log scaling factors greater than 0, avatar movements were augmented. For a log scaling factor of 0, no modulation was applied. Colored lines indicate the curve metrics derived: XY0.25 (green), XY0.50 = point of subjective equality (PSE) (red), and XY0.75 (blue). The PSE was close to 0 consistent with expectations for a two-alternative forced choice paradigm.
