This article provides evidence that motion has the ability to stably fuse two different colored ‘spatially separated’ stimuli without impairments against the shape of those separated stimuli. Based on our observations, dilated pupils promote colours fusion; and the optimal fusion happens when the stimuli are moving in opposite direction of the actual physical motion, namely, when there is illusory motion reversal. The previous observations suggested that retinal peripheries have main contributions on the present illusion which we called; motion induced colours fusion ‘MICF’ illusion.

This article provides evidence that the retinal peripheries generate motion reversal perception. Restricted access of the light rays to retinal peripheries due to pupil constriction is found to significantly limit the perception of motion reversal. We used unfolded stimulus, namely, a linear stimulus instead one a radial one to easily validate our theory.

The Rotating Snakes illusion is a motion illusion based on repeating, asymmetric luminance patterns. Recently, we found certain gray-value conditions where a weak illusory motion occurs in the opposite direction. Of the four models for explaining the illusion, one also explains the unexpected perceived opposite direction.We here present a simple new model, without free parameters, based on an array of standard correlation-type motion detectors with a subsequent nonlinearity (e.g., saturation) before summing the detector outputs. The model predicts (a) the pattern-appearance motion illusion for steady fixation, (b) an illusion under the real-world situation of saccades across or near the pattern (pattern shift), (c) a relative maximum of illusory motion for the same gray values where it is found psychophysically, and (d) the opposite illusion for certain luminance values. We submit that the new model’s sparseness of assumptions justifies adding a fifth model to explain this illusion.

AbstractThe Rotating Snakes illusion is a motion illusion based on repeating, asymmetric luminance patterns. Recently, we found certain grey-value conditions where a weak, illusory motion occurs in the opposite direction. Of the four models for explaining the illusion, one (Backus and Oruç, 2005) also explains the unexpected perceived opposite direction. We here present a simple new model, without free parameters, based on an array of standard correlation-type motion detectors with a subsequent non-linearity (e.g., saturation) before summing the detector outputs. The model predicts (1) the pattern-appearance motion illusion for steady fixation, (2) an illusion under the real-world situation of saccades across or near the pattern (pattern shift), (3) a relative maximum of illusory motion for the same grey values where it is found psychophysically, and (4) the inverse illusion for certain luminance values. We submit that the model’s sparseness of assumptions justifies adding a fifth model to explain this illusion.
