Weber-Fechner behavior in symmetry perception?
PA van der Helm - Attention, Perception, & Psychophysics, 2010 - Springer
The literature contains several allusions to the idea that detection of (mirror) symmetry in the
presence of noise follows the Weber-Fechner law. This law usually applies to first-order
structures, such as length, weight, or pitch, and it holds that just-noticeable differences in a
signal vary in proportion to the strength of the signal. Symmetry, however, is a higher order
structure, and this theoretical note starts from the idea that, in noisy symmetry, the regularity-
to-noise ratio defines the strength of the signal to be considered. We argue that the …
