Experiment 1, Dimensionality Reduction

Data for Experiment 1 can be reduced to a 2-D representation. The figure shows all observers' matches and the tests plotted in the transformed space. The left panel plots the third axis (D3) against the diffuse direction (D1) for the purple test condition. The right panel is in the same format but is for the yellow-green test condition. The symbols follow the same format as in Figure 4 of the paper.
