Human symmetry detection in dense patterns exhibits
a spatial integration range that becomes narrower with
distance of the symmetry axis from the fovea. This narrowing
violates the general properties of eccentricity that have
been found for all previous visual cortical areas, tasks,
and assessment techniques. This reverse eccentricity scaling
may, in conjunction with the long-range matching properties
for symmetry described in Tyler and Hardage (1996), imply
that symmetry is processed by a specialized cortical area
with non-retinotopic neural architecture.
