WebDivisive Normalization An important example is the use of probabilistic models [170] to account for divisive normalization. This is a mechanism whereby cells mutually inhibit one another, e ectively normalizing their responses with respect to stimulus inputs. Originally developed to explain non-linear responses to contrast in V1 [59], Webdependent choice. We nd that divisive normalization captures violations of the in-dependence of irrelevant alternatives that cannot be otherwise explained with salience theory, range normalization, or attraction e ect theories. Moreover, we identify a new setting in which the well-established attraction e ects do not occur. JEL: D03, D81, D87 solve matrix equation using cholesky
