Perceptual rivalry with vibrotactile stimuli

Perceptual Analysis of Vibrotactile Stimuli and Its Application to Vibrotactile Rendering of Music

Binocular rivalry and perceptual coherence

in E2 binding [17]. The equivalent position typically contains an aromatic or hydrophobic residue in the RING fingers and particularly in the U box, where it is almost invariably aromatic (Figure 1). The structural models show that this aromatic residue in the RING fingers and in the U-box domain is exposed (Figure 2) and could directly contribute to E2–ubiquitin binding via hydrophobic or arom...

Binocular Rivalry Stimuli are Common but Rivalry is not

Recently Arnold (2011) asked “Why is binocular rivalry uncommon?”. He answered in an entertainingly written, provocative article, for which I thank and congratulate him. However, I will argue that Arnold’s answer falls short in two respects and his assumption that rivalry is uncommon is correct for two reasons other than the one he discusses. Binocular rivalry is a phenomenon of human visual pe...

Fusion and Rivalry Are Dependent on the Perceptual Meaning of Visual Stimuli

We view the world with two eyes and yet are typically only aware of a single, coherent image. Arguably the simplest explanation for this is that the visual system unites the two monocular stimuli into a common stream that eventually leads to a single coherent sensation. However, this notion is inconsistent with the well-known phenomenon of rivalry; when physically different stimuli project to t...

Tri-stable stimuli reveal interactions among subsequent percepts: Rivalry is biased by perceptual history

In rivalry, constant stimuli allow several interpretations ("percepts"). Percepts are characterized by their probability to occur and by the duration of their dominance. During continuous presentation of bi-stable stimuli, both percept probabilities are trivially 50%. To disentangle the processes triggering a percept from those stabilizing it, we introduce tri-stable stimuli having three percep...
