Stimuli and Predicted Dissimilarity Matrices

(A) Predicted view-invariant gaze direction dissimilarity structure across the 25 computer-generated faces. The faces are sorted according to the nine distinct gaze directions in the stimulus set (left 40° to right 40° rotation), which were created by incrementally varying head view and eye position relative to the head (five increments between left 20° and right 20° for both).

(B) Predicted dissimilarity structures for the same faces based on alternative accounts of the data corresponding to their physical stimulus features (1-r across image grayscale intensities), head view, and qualitative gaze direction (left/direct/right gaze) ignoring quantitative differences between angles of left and right gaze. Dissimilarity matrices are sorted as in (A).
