Tomassini, A., Morgan, M. J. & Solomon, J. A. (2010). Orientation uncertainty reduces perceived obliquity. Vision Research, 50(5), pp. 541-547. doi: 10.1016/j.visres.2009.12.005
Abstract
The influence of prejudice on perception should be greatest when certainty about stimulus identity is least. We exploited this relationship to reveal visual biases for the cardinal orientations: vertical and horizontal. Specifically, when we increased the variance of orientations in an array of grating patches, estimates of the mean became less oblique. This result is consistent with a stable prior, or prejudice, for those orientations most prevalent in natural scenes.
