A simple model describes large individual differences in simultaneous colour contrast.
Vebjørn Ekroll,Franz Faul +1 more
TL;DR: It is argued that the von Kries component reflects theaction of a temporal adaptation mechanism, while the crispening component describes the action of the instantaneous, purely spatial mechanism most appropriately labeled simultaneous colour contrast.
Journal ArticleDOI
On the filter approach to perceptual transparency.
Franz Faul,Vebjørn Ekroll +1 more
TL;DR: It is shown that the parameters of the original model, which are closely related to physical properties, can be transformed into the alternative parameters hue H, saturation S, transmittance V, and clarity C that better reflect perceptual dimensions of perceived transparency.
Journal ArticleDOI
New laws of simultaneous contrast
Vebjørn Ekroll,Franz Faul +1 more
TL;DR: Within this theoretical framework, the universally presumed validity of the complementarity law and Kirschmann's fourth law can be understood as resulting from the failure to take various confounding factors into account when interpreting empirical data, the most prominent of which is the influence of temporal von Kries adaptation.
Journal ArticleDOI
The strengths of simultaneous colour contrast and the gamut expansion effect correlate across observers: Evidence for a common mechanism
TL;DR: It is suggested that this putatively common mechanism of 'crispening' accounts completely for the gamut expansion effect, and partially for the simultaneous colour contrast effect, which seems to depend on von Kries adaptation also.
Reference EntryDOI
Power Analysis for Categorical Methods
TL;DR: In this paper, the authors assess and control the power of chi-square tests for categorical data, including simple null hypotheses and composite null hypotheses for parameterized multinomial models requiring parameter estimation.
