Regularity is a ubiquitous feature of the visual world. We demonstrate that regularity is an
adaptable visual dimension: The perceived regularity of a pattern is reduced following
adaptation to a pattern with a similar or greater degree of regularity. Stimuli consisted of 7× 7
element arrays arranged on square grids presented in a circular aperture. The position of
each element was randomly jittered from its baseline position by an amount that determined
its degree of irregularity. The elements of the pattern consisted of dark Gaussian blobs …
