Face aftereffects are sensitive to changes in viewpoint, suggesting view-specific face coding, yet are not entirely eliminated by changes in viewpoint, suggesting view-invariance. To determine whether broad view-tuning can account for these findings we measured the reduction of a figural face aftereffect induced in one view by concurrent adaptation to an opposite distortion in a second viewpoint, varying the angle between these views. To the degree that the same neural population codes both viewpoints, the opposing aftereffects should cancel. Cancellation increased monotonically as the angle between two adapting views decreased, consistent with broadly tuned, view-specific coding of face shape.
