Fig. 5.
Classifier prediction performance for discriminating +60° vs. −30° slants for all regions of interest. Dashed lines indicate the performance predicted for combined-cue conditions based on quadratic summation of performance observed in the Texture and Disparity (single cue) conditions. Error bars indicate SE. Asterisks indicate areas where sensitivity for congruent cues significantly exceeded performance predicted by quadratic summation (dashed horizontal lines) (P < 0.05).
