Global competition dictates local suppression in pattern rivalry

Global competition dictates local suppression in pattern rivalry.

Certain pairs of visual patterns, when superimposed as if transparent, elicit a wavering percept in which one or the other pattern can enjoy temporary periods of exclusive visibility. This multistable perceptual phenomenon is called monocular rivalry or pattern rivalry (PR) and is most pronounced when the component patterns are faint and devoid of detail. The principal mechanisms that give rise...

Local binocular fusion is involved in global binocular rivalry

We examined whether interocular inhibition in binocular rivalry could occur at the interocular intersection of horizontal and vertical rectangular patches which are locally fusible but globally rivalrous between the two eyes. We measured contrast increment (and decrement) thresholds of a monocularly presented probe which was presented on the horizontal patch corresponding to the intersection. W...

From Local to Global Competition¤

We introduce a framework that has known models of oligopolistic competition with di®erentiated products (the circle, the logit, and the CES) as limit cases. This integrative approach incorporates both localized and global competition, as well as price-sensitive individual demands. It is used to explain the impact of major changes over the last two centuries: reductions in transport costs, incre...

Interactions between global motion and local binocular rivalry

Binocular rivalry is thought to arise from a low-level cortical site. Experiment 1 evaluates this claim with respect to local and global motion processing by using a multiple-aperture motion stimulus and measuring the predominance of global coherence while one of the component gratings is engaged in rivalry. Results show that rivalry suppression of the component grating precludes global coheren...
