Measuring Configural Superiority with the Capacity Coefficient

open access: yesJournal of Vision, 2013
Configural superiority effects are an important component of our understanding of visual perception of many types of stimuli. We propose the capacity coefficient as common framework for measuring configural superiority across a wide range of stimulus types. This measure has a number of advantages.

On an extremal configuration for capacity

open access: yesArkiv för Matematik, 1989
One main result concerns a set \(E\) on the unit circle consisting of a fixed number \(n\) of arcs with total length \(L\). Let \(E^*\) be the set whose arcs have equal length \(L/n\) and are symmetrically distributed around the circle. Then \[ \hbox{cap} E\leq\hbox{cap} E^*=\{\sin L/4\}^{1/n}.
