“…This work has again underscored the generality of some of the findings we discussed, by revealing striking parallels with visual bistability (Carter et al, 2008;Davidson & Pitts, 2014;Holcombe & SeizovaCajic, 2008;Hupé et al, 2008;McKendrick et al, 2011;Pressnitzer & Hupé, 2006;Snyder, Holder, et al, 2009;. The work has also suggested experimental handles that might be used to control stimulus strength in non-vision paradigms, inviting a systematic evaluation of Levelt's propositions outside of the visual domain.…”

“…A considerable number of recent studies have focused on perceptual bistability outside of vision, namely in the domains of audition (Davidson & Pitts, 2014;Denham & Winkler, 2006;Hupé, Joffo, & Pressnitzer, 2008;Moore & Gockel, 2012;Pressnitzer & Hupé, 2006;, haptics (Carter et al, 2008;Holcombe & Seizova-Cajic, 2008), proprioception (Holcombe & Seizova-Cajic, 2008) and olfaction (Zhou & Chen, 2009).

The ‘laws’ of binocular rivalry: 50 years of Levelt’s propositions

It has been fifty years since Levelt's monograph On Binocular Rivalry (1965) was published, but its four propositions that describe the relation between stimulus strength and the phenomenology of binocular rivalry remain a benchmark for theorists and experimentalists even today. In this review, we will revisit the original conception of the four propositions and the scientific landscape in which this happened. We will also provide a brief update concerning distributions of dominance durations, another aspect of Levelt's monograph that has maintained a prominent presence in the field. In a critical evaluation of Levelt's propositions against current knowledge of binocular rivalry we will then demonstrate that the original propositions are not completely compatible with what is known today, but that they can, in a straightforward way, be modified to encapsulate the progress that has been made over the past fifty years. The resulting modified, propositions are shown to apply to a broad range of bistable perceptual phenomena, not just binocular rivalry, and they allow important inferences about the underlying neural systems. We argue that these inferences reflect canonical neural properties that play a role in visual perception in general, and we discuss ways in which future research can build on the work reviewed here to attain a better understanding of these properties.

“…First, because the model can take as input any auditory signal, it opens the door to future efforts to integrate our understanding of auditory bistability across multiple paradigms. Human listeners show apparent bistable responses to a number of other auditory stimuli, including Shepard tones [95][96][97] and repeated words [6]; natural extensions of our Central and Object stages of processing could be used to model these additional tasks. Second, it provides a useful test of simpler, more abstracted models of adaptation, inhibition and noise [18,19,38,42,43,45].…”

AbstractPerceptual bistability—the spontaneous fluctuation of perception between two interpretations of a stimulus—occurs when observing a large variety of ambiguous stimulus configurations. This phenomenon has the potential to serve as a tool for, among other things, understanding how function varies across individuals due to the large individual differences that manifest during perceptual bistability. Yet it remains difficult to interpret the functional processes at work, without knowing where bistability arises during perception. In this study we explore the hypothesis that bistability originates from multiple sources distributed across the perceptual hierarchy. We develop a hierarchical model of auditory processing comprised of three distinct levels: a Peripheral, tonotopic analysis, a Central analysis computing features found more centrally in the auditory system, and an Object analysis, where sounds are segmented into different streams. We model bistable perception within this system by injecting adaptation, inhibition and noise into one or all of the three levels of the hierarchy. We evaluate a large ensemble of variations of this hierarchical model, where each model has a different configuration of adaptation, inhibition and noise. This approach avoids the assumption that a single configuration must be invoked to explain the data. Each model is evaluated based on its ability to replicate two hallmarks of bistability during auditory streaming: the selectivity of bistability to specific stimulus configurations, and the characteristic log-normal pattern of perceptual switches. Consistent with a distributed origin, a broad range of model parameters across this hierarchy lead to a plausible form of perceptual bistability. The ensemble also appears to predict that greater individual variation in adaptation and inhibition occurs in later stages of perceptual processing.Author summaryOur ability to experience the everyday world through our senses requires that we resolve numerous ambiguities present in the physical evidence available. This is accomplished, in part, through a series of hierarchical computations, in which stimulus interpretations grow increasingly abstract. Our ability to resolve ambiguity does not always succeed, such as during optical illusions. In this study, we examine a form of perceptual ambiguity called bistability—cases in which a single individual’s perception spontaneously switches back and forth between two interpretations of a single stimulus. A challenge in understanding bistability is that we don’t know where along the perceptual hierarchy it is generated. Here we test the idea that there are multiple origins by building a simulation of the auditory system. Consistent with a multi-source account of bistability, this simulation accurately predicts perception of a simple auditory stimulus when bistability originates from a number of different sources within the model. The data also indicate that individual differences during ambiguous perception may primarily originate from higher levels of the perceptual hierarchy. This result provides a clue for future work aiming to determine how auditory function differs across individual brains.

“…Third, there are many additional bistable and multistable paradigms to consider modeling [6,33,34,[112][113][114][115][116][117]. A first step towards handling these paradigms could be to extend the features included in the Central analysis to spectral-temporal features.…”

Ensemble modeling of auditory streaming reveals potential sources of bistability across the perceptual hierarchy

Perceptual bistability-the spontaneous, irregular fluctuation of perception between two interpretations of a stimulus-occurs when observing a large variety of ambiguous stimulus configurations. This phenomenon has the potential to serve as a tool for, among other things, understanding how function varies across individuals due to the large individual differences that manifest during perceptual bistability. Yet it remains difficult to interpret the functional processes at work, without knowing where bistability arises during perception. In this study we explore the hypothesis that bistability originates from multiple sources distributed across the perceptual hierarchy. We develop a hierarchical model of auditory processing comprised of three distinct levels: a Peripheral, tonotopic analysis, a Central analysis computing features found more centrally in the auditory system, and an Object analysis, where sounds are segmented into different streams. We model bistable perception within this system by applying adaptation, inhibition and noise into one or all of the three levels of the hierarchy.
