title: Arcs in perceptual space--going off at a tangent.
abstract: Underestimating the curvature of an arc may result from our tendency to view it as prolonged in the direction of the tangent to its ends. Support is given here for this hypothesis, but evidence is also provided that tangent deviation may alter an arc's circularity along its whole length.
