A novel illusion of bars made from triangles

Academic Article


  • A repetitive pattern of a triangular luminance profile may be perceived as a triangular-wave grating or as a square-wave grating. This illusion may reflect the operation of cortical phase-selective mechanisms that are biased toward particular phase relations and favor abrupt luminance gradients. Copyright © 1981 AAAS.
