Figure Legend: From: Probing intermediate stages of shape processing Journal of Vision. 2015;15(7):1. doi:10.1167/15.7.1 Figure Legend: Dependence of angle discrimination and appearance on the shape of the triangle containing the angle (A). (B) Angle discrimination is significantly better (thresholds lower) when angles are embedded in isosceles triangles (light gray bar) compared to scalene (dark gray) or randomly shaped triangles (black). (C) The shape of the triangle also affects the appearance of the angular magnitude. Comparing angles embedded in various scalene triangles to those that are part of an isosceles shape shows systematic biases. Scalene angles are judged smaller than matching isosceles angles, and the magnitude of the bias increases with increasing ratio of the sides that enclose the scalene angle. The two top angles in (A) are the same, but observers typically judge the isosceles as more obtuse. (B) and (C) adapted with permission from Kennedy et al.
