  15. Suppression Size: parafoveal Depth: shallow @ near deep @ distance Constancy: intermittent Laterality: mostly O.D. (more alternating @ near) At what viewing distance: dist. < near Retinal Correspondence Normal: nope! Anomalous: uARC mostly Depth: very deep At what viewing distance:ARC at all distances Summary For “Sally”
