Traditional explanations of multistable visual phenomena (e.g. ambiguous figures, perceptual rivalry) suggest that the basis for spontaneous reversals in perception lies in antagonistic connectivity within the visual system. In this review, we suggest an alternative, albeit speculative, explanation for visual multistability – that spontaneous alternations reflect responses to active, programmed events initiated by brain areas that integrate sensory and non-sensory information to coordinate a diversity of behaviors. Much evidence suggests that perceptual reversals are themselves more closely related to the (...) expression of a behavior than to passive sensory responses: (1) they are initiated spontaneously, often voluntarily, and are influenced by subjective variables such as attention and mood; (2) the alternation process is greatly facilitated with practice and compromised by lesions in non-visual cortical areas; (3) the alternation process has temporal dynamics similar to those of spontaneously initiated behaviors; (4) functional imaging reveals that brain areas associated with a variety of cognitive behaviors are specifically activated when vision becomes unstable. In this scheme, reorganizations of activity throughout the visual cortex, concurrent with perceptual reversals, are initiated by higher, largely non-sensory brain centers. Such direct intervention in the processing of the sensory input by brain structures associated with planning and motor programming might serve an important role in perceptual organization, particularly in aspects related to selective attention.

A central question in philosophical and sociological accounts of technology is how the agency of technologies should be conceived, that is, how to understand their constitutive roles in the actions performed by assemblages of humans and artifacts. To address this question, I build on the suggestion that a helpful perspective can be gained by amalgamating “actor-network theory” and “postphenomenological” accounts. The idea is that only a combined account can confront both the nuances of human experiential relationships with technology on which (...) postphenomenology specializes, and also the chains of interactions between numerous technologies and humans that actor-network theory can address. To perform this amalgamation, however, several technical adjustments to these theories are required. The central change I develop here is to the postphenomenological notion of “multistability,” i.e., the claim that a technology can be used for multiple purposes through different contexts. I expand the postphenomenological framework through the development of a method called “variational cross-examination,” which involves critically contrasting the various stabilities of a multistable technology for the purpose of exploring how a particular stability has come to dominate. As a guiding example, I explore the case of the everyday public bench. The agency of this “mundane artifact,” as actor-network theorist Bruno Latour would call it, cannot be accounted for by either postphenomenology or actor-network theory alone. (shrink)

In this paper, in the first place, I aim to enquire into Bernard Stiegler’s critical appropriation of his mentor Jacques Derrida’s notion of différance, emphasizing how Stiegler’s philosophy of technology stems from an original interpretation of the main tenets of deconstruction. From this perspective, I will investigate Stiegler’s definition of technology as tertiary retention, i.e., exosomatized, artificial memory interrelating with biological memory, testing its hermeneutic strengths as well as possible weaknesses. In the second place, I aim to contrast Stiegler’s understanding (...) of technology with the concept of multistability brought forward by postphenomenological philosophies of technology such as those elaborated by Don Ihde and Peter-Paul Verbeek. This investigation will enable me to submit that Stiegler’s approach represents a peculiar and innovative way to conceive of technology. On the one hand, indeed, it does not seem to fall prey to the criticisms raised by postphenomenology against traditional philosophies of technology such as Martin Heidegger’s or Jacques Ellul’s, deemed to be overly deterministic, abstract and pessimistic in their understanding of technology. On the other, it retains important methodological precautions from deconstruction, thereby pointing at some possible blind spots of postphenomenology, especially concerning the vexed question of the empirical-transcendental divide, which Stiegler aims to develop beyond both Derrida’s and postphenomenology’s stances.

A central issue in postphenomenology is how to explain the multistability of technologies: how can it be that specific technologies can be used for a wide variety of purposes (the “multi”), while not for all purposes (the “stability”)? For example, a table can be used for the purpose of sleeping, having dinner at, or even for staging a fencing match, but not for baking a cake. One explanation offered in the literature is that the (material) design of a technology (...) puts constraints on the purposes for which technologies can be used. In this paper, I argue that such an explanation—while partly correct—fails to address the role of the environment in which human beings operate in putting constraints on technology use. I suggest that James Gibson’s affordance theory helps highlighting how stabilities in technology use arise in the interaction between human being and environment. Building on more recent approaches in affordance theory, I suggest that the environment can be conceptualized as a “rich landscape of affordances” that solicits certain actions, which are not just cued by the environment’s material structure, but also by the normativity present in the form of life in which a human being participates. I briefly contrast the approach to affordances developed in this paper with how Klenk (2020) and Tollon (2021) have conceptualized the “affordance character” of technological artifacts, and highlight how a focus on the situated nature of affordances augments these earlier conceptualizations.

In this paper, a discrete-time dynamic duopoly model, with nonlinear demand and cost functions, is established. The properties of existence and local stability of equilibrium points have been verified and analyzed. The stability conditions are also given with the help of the Jury criterion. With changing of the values of parameters, the system shows some new and interesting phenomena in terms to stability and multistability, such as V-shaped stable structures and different shape basins of attraction of coexisting attractors. The (...) eye-shaped structures appear where the period-doubling and period-halving bifurcations occur. Finally, by utilizing critical curves, the changes in the topological structure of basin of attraction and the reason of “holes” formation are analyzed. As a result, the generation of global bifurcation, such as contact bifurcation or final bifurcation, is usually accompanied by the contact of critical curves and boundary. (shrink)

In this paper, a 4D fractional-order centrifugal flywheel governor system is proposed. Dynamics including the multistability of the system with the variation of system parameters and the derivative order are investigated by Lyapunov exponents, bifurcation diagram, phase portrait, entropy measure, and basins of attraction, numerically. It shows that the minimum order for chaos of the fractional-order centrifugal flywheel governor system is q = 0.97, and the system has rich dynamics and produces multiple coexisting attractors. Moreover, the system is controlled (...) by introducing the adaptive controller which is proved by the Lyapunov stability theory. Numerical analysis results verify the effectiveness of the proposed method. (shrink)

The notion of “multistability” is a central fixture of the postphenomenological framework of thought, one of the central ideas that enables this perspective to avoid both shallow determinism and instrumentalism.

This is a commentary piece on Marco Pavanini's article ' ‘Multistability and Derrida’s Différance: Investigating the Relations Between Postphenomenology and Stiegler’s General Organology' in which I critically extend upon his comparative analysis of postphenomenology''s notion of multistability and Stiegler's conception of organology, focusing in particular on the pharmacological nature of Stiegler's organology and the latter's most recent re-interpretation of it in terms of entropy and negentropy. Among other things I show, and both are more intended as additions than (...) criticisms with respect to Pavanini’s very helpful comparison, that the most important concern for Stiegler in theorizing technology is the fact that the transductive relations between the three organ systems distinguished in his pharmaco-organology of technology open up affective or libidinal circuits between these systems, i.e., circuits either of desire or drive depending on the way the pharmakon is adopted or not, and that these circuits are fundamentally noetic circuits vulnerable to denoetization; and that these libidinal-noetic circuits as conditioned by technology should be interpreted in terms of entropy and negentropy. Both insights are lacking in postphenomenology, which generally fails to consider the irreducibly destitutive character of all technology, rightfully emphasized by Pavanini, since it lacks a genuine pharmacological awareness.

Modern health care is inextricably bound up with technologically mediated knowledge and practice. It is vital to investigate its use and role in different clinical contexts characterized, on one hand, by face to face practitioner and patient encounters (where technology may be conceptualised as hindering therapeutic relations) and, on the other hand, by practitioners’ encounter with bodily parts in laboratories (where conceiving of patients may be thought of as confounding objectivity). To contribute to the latter, I offer an ethnographic analysis (...) of cytology laboratory practitioners’ work and microscopic assessment of normal and abnormal cells. First, I discuss the biomedical literature on cytology and the quest for a non-variational bodiless vision. Second, I discuss the concept of multistability, first developed by philosopher of technology Don Ihde, here used to analyse technologically mediated perception and how practitioners interact with technology. Combined with long term ethnographic fieldwork it enables access to, and analysis and articulation of the implicit multifaceted practitioner–technology–cell interface embedded in clinical practice and diagnostic processes. I will also address some implications of my analysis for clinical cytology. (shrink)

The Necker cube and the productive class of related stimuli involving multiple depth interpretations driven by corner-like line junctions are often taken to be ambiguous. This idea is normally taken to be as little in need of defense as the claim that the Necker cube gives rise to multiple distinct percepts. In the philosophy of language, it is taken to be a substantive question whether a stimulus that affords multiple interpretations is a case of ambiguity. If we take into account (...) what have been identified as hallmark features of ambiguity and look at the empirical record, it appears that the Necker cube and related stimuli are not ambiguous. I argue that this raises problems for extant models of multistable perception in cognitive neuroscience insofar as they are purported to apply to these stimuli. Helpfully, similar considerations also yield reasons to suggest that the relevant models are well motivated for other instances of multistable perception. However, a different breed of model seems to be required for the Necker cube and related stimuli. I end with a sketch how one may go about designing such a model relying on oscillatory patters in neural firing. I suggest that distinctions normally confined to the philosophy of language are important for the study of perception, a perspective with a growing number of adherents. (shrink)

We explore experimental methods used to study the phenomena of perceptual organization, first studied by the Gestalt psychologists. We describe an application of traditional psychophysics to perceptual organization and offer alternative methods. Among these, we distinguish two approaches that use multistable stimuli: (1) phenomenological psychophysics, in which the observer's response is assumed to accurately and directly reflect perceptual experience; and (2) the interference paradigm, in which an observer's response is evaluated as correct or incorrect because it pertains to a corrigible (...) task, but does not directly reflect the observer's experience. We show that phenomenological psychophysics can yield valuable information about perceptual organization and lends itself to the development of quantitative theory. We discuss some criticisms of the method and argue that the two approaches that use multistable stimuli are complementary. We also compare each of the approaches with traditional psychophysics. We conclude that the several methods are convergent. (shrink)

This article is an extended commentary inspired by Alan Drengson's paper “Shifting Paradigms: From Technocrat to Planetary Person” (Drengson 2011). In this article Susan Greenwood and I echo Drengson's criticism that Euro-American science is incomplete, having committed what Thomas Roberts calls “The Singlestate Fallacy: the erroneous assumption that all worthwhile abilities reside in our normal, awake mindbody state” (Roberts 2006:105). This singlestate fallacy is vividly portrayed in Mary Shelley's novel Frankenstein, whose critique of Euro-American science is revisited in this article. (...) Alternatively, Greenwood and I suggest that what is needed is a multimodel framework “that allows for in-depth analysis of the different modes of consciousness.” Roberts refers to this alternative attitude toward science as the Multistate Paradigm. An awareness of the transformational character of shamanism is also explored in this article as a means to overcome the oppositions between the technocratic and person planetary perspective, and their related gender associations.

Expanded new edition of the landmark book demonstrating the practice of phenomenology through visual illusions and ambiguous drawings.

How should we understand postphenomenological methodology? Postphenomenology is a research perspective which builds on phenomenological and pragmatist philosophy to explore human–technology relations, but one with open methodological questions. Here, I offer some thoughts on the epistemological processes that should be (and often implicitly may be) at work in this research. In particular, I am concerned with postphenomenological research on technological “multistability,” i.e., a device’s ever-present capacity to be used for a variety of purposes, and to always be meaningful in (...) multiple ways. I develop a methodology called “variational cross-examination,” which entails the critical contrast of a device’s various stabilities. As a set of instructive examples, I draw on my own line of research on the politics of public spaces, and especially the critique of anti-homeless design. (shrink)

In this paper, a novel no-equilibrium 5D memristive hyperchaotic system is proposed, which is achieved by introducing an ideal flux-controlled memristor model and two constant terms into an improved 4D self-excited hyperchaotic system. The system parameters-dependent and memristor initial conditions-dependent dynamical characteristics of the proposed memristive hyperchaotic system are investigated in terms of phase portrait, Lyapunov exponent spectrum, bifurcation diagram, Poincaré map, and time series. Then, the hidden dynamic attractors such as periodic, quasiperiodic, chaotic, and hyperchaotic attractors are found under (...) the variation of its system parameters. Meanwhile, the most striking phenomena of hidden extreme multistability, transient hyperchaotic behavior, and offset boosting control are revealed for appropriate sets of the memristor and other initial conditions. Finally, a hardware electronic circuit is designed, and the experimental results are well consistent with the numerical simulations, which demonstrate the feasibility of this novel 5D memristive hyperchaotic system.

Due to the introduction of memristors, the memristor-based nonlinear oscillator circuits readily present the state initial-dependent multistability, i.e., coexisting multiple attractors. The dimensionality reduction modeling for a memristive circuit is carried out to realize accurate prediction, quantitative analysis, and physical control of its multistability, which has become one of the hottest research topics in the field of information science. Based on these considerations, this paper briefly reviews the specific multistability phenomenon generating from the memristive circuit in the (...) voltage-current domain and expounds the multistability control strategy. Then, this paper introduces the accurate flux-charge constitutive relation of memristors. Afterwards, the dimensionality reduction modeling method of the memristive circuits, i.e., the incremental flux-charge analysis method, is emphatically introduced, whose core idea is to implement the explicit expressions of the initial conditions in the flux-charge model and to discuss the feasibility and effectiveness of the multistability reconstitution of the memristive circuits using their flux-charge models. Furthermore, the incremental integral transformation method for modeling of the memristive system is reviewed by following the idea of the incremental flux-charge analysis method. The theory and application promotion of the dimensionality reduction modeling and multistability reconstitution are proceeded, and the application prospect is prospected by taking the synchronization application of the memristor-coupled system as an example.

Simple models for the evolution of qualitative multistate traits are considered, in which the traits are permitted to evolve in time-dependent versus speciation-dependent fashion. Of particular interest are the means and variances of distances for these traits in evolutionary phylads characterized by different rates of speciation, when alternative characters are neutral with respect to fitness, and when the total number of observable characters is limited to small values. As attainable character states are increasingly restricted, mean distance (D) in a phylad (...) decreases, regardless of whether evolution is a function of time or of rate of speciation. The ratio of mean distances in species-rich and species-poor phylads of comparable evolutionary age (DR/DP) remains near one when differentiation is proportional to time, even when attainable character states are severely restricted. DR/DP also nears one as a result of restricting character states when differentiation is proportional to rate of speciation, but the effect is not severe unless the number of character states is very small and the probability of change per speciation very large. These and other results are discussed with reference to available data sets on qualitative multistate traits. (shrink)

Due to the complex behavior of a multiscroll chaotic system, it is a good candidate for the secure communications. In this paper, by adding an additional variable to the modified Lorenz-type system, a new chaotic system that includes only linear and piecewise items but can generate 4n + 4 scroll chaotic attractors via choosing the various values of natural number n is proposed. Its dynamics including bifurcation, multistability, and symmetric coexisting attractors, as well as various chaotic and periodic behaviors, (...) are analyzed by means of attraction basin, bifurcation diagram, dynamic map, phase portrait, Lyapunov exponent spectrum, and C0 complexity in detail. The mechanism of the occurrence for generating multiscroll chaotic attractors is presented. Finally, this multiscroll chaotic system is implemented by using the Altera Cyclone IV EP4CE10F17C8 FPGA. It is found that this FPGA-based design has an advantage of requiring less resources for 0% of the embedded multipliers and 0% of the PLLs of this FPGA are occupied. (shrink)

Here, a novel conservative chaotic oscillator is presented. Various dynamics of the oscillator are examined. Studying the dynamical properties of the oscillator reveals its unique behaviors. The oscillator is multistable with symmetric dynamics. Equilibrium points of the oscillator are investigated. Bifurcations, Lyapunov exponents, and the Poincare section of the oscillator’s dynamics are analyzed. Also, the oscillator is investigated from the viewpoint of initial conditions. The study results show that the oscillator is conservative and has no dissipation. It also has various (...) dynamics, such as equilibrium point and chaos. The stability analysis of equilibrium points shows there are both stable and unstable fixed points. (shrink)

Except the two types of state, complete failure and perfect functioning, some intermediate states also existed between those two states. This characteristic enables multistate system whose components are often of more than two states. Moreover, because of dependence between components, common cause failure enhances the failure risk of components during the operating period of MSS. A protection mechanism needs to be adopted because of the importance of certain components. For a MSS with CCF and protection mechanism, its reliability can be (...) evaluated by a proposed approach. Certain components not only can cause failure at one state, but also can cause failure to other components because of the CCF. Under the impact of one type of CCF, those components can constitute a specific group that can overlap with certain components. Universal generating function is adopted to incorporate the CCF and protection mechanism of a component. Consequently, reliability indices of a MSS can be evaluated by the proposed approach based on UGF. Examples and comparisons illustrate and validate this method. This method can also help engineers prioritize elements that require protection mechanism under various resource limitations. (shrink)

Based on a nonlinear demand function and a market-clearing price, a cobweb model is introduced in this paper. A gradient mechanism that depends on the marginal profit is adopted to form the 1D discrete dynamic cobweb map. Analytical studies show that the map possesses four fixed points and only one attains the profit maximization. The stability/instability conditions for this fixed point are calculated and numerically studied. The numerical studies provide some insights about the cobweb map and confirm that this fixed (...) point can be destabilized due to period-doubling bifurcation. The second part of the paper discusses the memory factor on the stabilization of the map’s equilibrium point. A gradient mechanism that depends on the marginal profit in the past two time steps is adopted to incorporate memory in the model. Hence, a 2D discrete dynamic map is constructed. Through theoretical and numerical investigations, we show that the equilibrium point of the 2D map becomes unstable due to two types of bifurcations that are Neimark–Sacker and flip bifurcations. Furthermore, the influence of the speed of adjustment parameter on the map’s equilibrium is analyzed via numerical experiments. (shrink)

In recent years, the research of chaos theory has developed from simple cognition and analysis to practical engineering application. In particular, hyperchaotic systems with more complex and changeable chaotic characteristics are more sensitive and unpredictable, so they are widely used in more fields. In this paper, two important engineering applications based on hyperchaos pseudorandom number generator and image encryption are studied. Firstly, the coupling 6D memristive hyperchaotic system and a 2D SF-SIMM discrete hyperchaotic mapping are used as the double entropy (...) source structure. The double entropy source structure can realize a new PRNG that meets the security requirements, which can pass the NIST statistical test when the XOR postprocessing method is used. Secondly, based on the double entropy source structure, a new image encryption algorithm is proposed. The algorithm uses the diffusion-scrambling-diffusion encryption scheme to realize the conversion from the original plaintext image to the ciphertext image. Finally, we analyze the security of the proposed PRNG and image encryption mechanism, respectively. The results show that the proposed PRNG has good statistical output characteristics and the proposed image encryption scheme has high security, so they can be effectively applied in the field of information security and encryption system.

This article offers a discussion of the connection between technology and values and, specifically, I take a closer look at ethically sound design. In order to bring the discussion into a concrete context, the theory of Value Sensitive Design (VSD) will be the focus point. To illustrate my argument concerning design ethics, the discussion involves a case study of an augmented window, designed by the VSD Research Lab, which has turned out to be a potentially surveillance-enabling technology. I call attention (...) to a “positivist problem” that has to do with the connection between the design context and the use context, which VSD seems to presuppose, and I argue that it is necessary to clearly distinguish between the two, since the designers’ intentions do not always correspond with the users’ practice; in fact, the relation between design and use is very complex and principally unpredictable. Thus, a design theory must accept that foresight is limited to anticipation rather than prediction. To overcome the positivist problem, I suggest a phenomenological approach to technology inspired by Don Ihde’s concept of multistability. This argument, which is general in nature and thus applies to any theory of design ethics, is intended as a constructive criticism, which can hopefully contribute to the further development of design ethics.

This article connects value-sensitive design to Gibson’s affordance theory: the view that we perceive in terms of the ease or difficulty with which we can negotiate space. Gibson’s ideas offer a nonsubjectivist way of grasping culturally relative values, out of which we develop a concept of political affordances, here understood as openings or closures for social action, often implicit. Political affordances are equally about environments and capacities to act in them. Capacities and hence the severity of affordances vary with age, (...) health, social status and more. This suggests settings are selectively permeable, or what postphenomenologists call multistable. Multistable settings are such that a single physical location shows up differently – as welcoming or hostile – depending on how individuals can act on it. In egregious cases, authoritarian governments redesign politically imbued spaces to psychologically cordon both them and the ideologies they represent. Selective permeability is also orchestrated according to business interests, which is symptomatic of commercial imperatives increasingly dictating what counts as moral and political goods. (shrink)

Phenomenology and experimental psychology have been largely interested in the same thing when it comes to attention. By building on the work of Aron Gurwitsch, especially his ideas of attention and restructuration, this paper attempts to articulate common ground in psychology and phenomenology of attention through discussion of a new way to think about multistability in some phenomena. What psychology views as an attentionality-intentionality phenomenon, phenomenology views as an intentionality-attentionality phenomenon. The proposal is that an awareness of this restructuring (...) of attentionality and intentionality can benefit both approaches to attention. After reviewing Husserl’s position on attentionality and intentionality, this paper examines multistable phenomena, redefines the attentional transformation called restructuring, discusses disciplinary perspectives on attention and gives an example using common ground.

The emerging school of thought called “postphenomenology” offers a distinct understanding of the ways that people experience technology usage. This perspective combines insights from the philosophical tradition of phenomenology with commitments to the anti-essentialism and nonfoundationalism of American pragmatism. One of postphenomenology’s central positions is that technologies always remain “multistable,” i.e., subject to different uses and meanings. But I suggest that as this perspective matures, philosophical problems are emerging around the notion of multistability, what I call “the problem of (...) invariance” and “the problem of grounding.” These problems point out things that remain unclear within the postphenomenological framework, such as how it handles structural claims regarding a technology’s various stabilities, and how it grounds its claims. How can postphenomenology make structural claims about technology and yet remain anti-essentializing? And on what epistemological basis does it ground its claims about human-technology relations? The paper concludes with a series of prescriptions that, if followed, enable postphenomenology to make edifying claims about technology, all while avoiding the problems of invariance and grounding, and maintaining its commitments to anti-essentialism and nonfoundationalism.

Multistability—the plurality of meanings of technological artifacts—is an emancipatory phenomenon insofar as it allows the user to freely appropriate the object according to his or her interests, even against the will of the designer. The objective of this article is to show how the trend to connect physical and digital artifacts to the Internet poses a danger to the freedom that there is in multistability. By reducing the traditional separation between the artifact and the designer, the connection of (...) the artifact to the Internet allows the designer to continually modify the software that governs or constitutes it, which involves a relative loss of power for the user to determine its meaning. This change, in favor of the designer in the correlation of power among the actors—designer, artifact, and user—from whose interplay the meaning of artifacts arises, favors concentric stabilities and hinders eccentric ones with respect to the will of the designer. Thus, we should rethink the truth value of the designer fallacy, that is, the claim that the meaning of artifacts is determined only by the designer. From a political point of view, the remote control of artifacts and their multistability is an effective pedagogical tool to educate human beings in a time in which texts, according to Sloterdijk, no longer serve this function.
