The “binding problem” has been a central question in vision science for some 30 years: When encoding multiple objects or maintaining them in working memory, how are we able to represent the correspondence between a specific feature and its corresponding object correctly? In this letter we argue that the boundaries of this research program in fact extend far beyond vision, and we call for coordinated pursuit across the broader cognitive science community of this central question for cognition, which (...) we dub “Binding Problem 2.0”.

(von der Malsburg, 1981), “the binding problem” has with the visual percept of it, so that both are effortlessly captured the attention of researchers across many disci- perceived as being aspects of a single event. I like to plines, including psychology, neuroscience, computa- refer to these sorts of problems as perceptual binding tional modeling, and even philosophy. Despite the is- problems, since they involve unifying aspects of per- sue’s prominence in these fields, what “binding” means cepts. (...) In addition, there are cognitive binding problems: is rarely made explicit. In this paper, I will briefly survey they include relating a concept to a percept, such as the many notions of binding and will introduce some linking the visual representation of an apple to all the issues that will be explored more fully in the reviews semantic knowledge stored about it (it is edible, how it that follow.

Our brains process visual data in segregated, specialized cortical areas. As is commonly remarked, the brain processes the what and the where of its environment in separate, distal locations. Indeed, regarding the what information that the brain computes, it responds to edges, colors, and movements using different neuronal pathways. Moreover, so far as we can tell, there are no true association areas in our cortices. There are no convergence zones where information is pooled and united; there are no central neural (...) areas dedicated to information exchange. Still, the visual features that we extract separately have to come together in some way, since our experiences are of these features united together into a single unit. The binding problem is explaining how our brains do that, given the serial, distributed nature of our visual processing. How do our minds know to join the perception of a shape with the perception of its color to give us the single, unified experience of a colored object? (shrink)

It is important to separate the question of binding from the problem of consciousness. Undoubtedly, there are some close connections between the two: my conscious experience is of a bound unity. But my unconscious experiences -- subliminal impressions, masked primings, etc. -- might be bound too for all I know. Hence, some of the recent commentators speak too loosely when they talk of 40 Hz oscillations solving some problem of conscious perception.

How do separate brain processes bind to form unified, conscious percepts? This is the perceptual binding problem, which straddles neuroscience and psychology. In fact, two problems exist here: (1) the easy problem of how neural processes are unified, and (2) the hard problem of how this yields unified perceptual consciousness. Binding theories face familiar troubles with (1) and they do not come to grips with (2). This paper argues that neuroelectrical (electromagnetic-field) approaches may help with (...) both problems. Concerning the easy problem, standard accounts of neural binding by synchrony, attention, and convergence raise serious difficulties. These are avoided by neuroelectrical approaches in which the brain’s field binds distributed processes in myriad neurons. Concerning the hard problem, binding theories do not squarely address how to get from neural unity to unified consciousness. This raises metaphysical difficulties involving reductions, emergence, etc. Neuroelectrical (and Russellian) approaches may help avoid these difficulties too. These approaches may thus deserve further investigation as binding theories. (shrink)

The binding problem is fundamental to visual perception. It is the problem of associating an object's visual properties with itself and not with some other object. The problem is made particular difficult because different properties of an object, such as its color, shape, size, and motion, are often processed independently, sometimes in different cortical areas. The results of these separate analyses have to be combined before the object can be seen as a single coherent entity as (...) opposed to a collection of unconnected features. Visual bindings are typically initiated and updated in a serial fashion, one object at a time. Here, we show that one type of binding, location-identity bindings, can be updated in parallel. We do this by using two complementary techniques, the simultaneous-sequential paradigm and systems factorial technology. These techniques make different assumptions and rely on different behavioral measures, yet both came to the same conclusion. (shrink)

In this article, I explicate a new problem for a variant of panpsychism, strong experiential monism, that is the view that all being is experiential. I contrast the view with weak experiential monism, a softer variant that allows for non-experiential bare particulars to act as the carriers of properties. I argue that strong experiential monism can’t explain what works as the ontological commonality between the referents of one experience of something and another experience of that same thing; in other (...) words, in virtue of what are those experiences about the same thing at all. If they aren’t about the same ontological existent at all, the apparent mutual coherence between these experiences (as manifest in our ability to discuss about them in a seemingly coherent way, for example) requires explanation. I argue that strong experiential monism necessitates a more or less brute kind of parallelism between the experiences to explain their mutual coherence. Alternatively, the strong experiential monist must either retreat to weak experiential monism and non-experiential bare particulars or to a more robust kind of property dualism or dual-aspect monism.

The binding problem is to explain how information processed by different sensory systems is brought together to unify perception. The problem has two sides. First, we want to explain phenomenal binding: the fact that we experience a single world rather than separate perceptual fields for each sensory modality. Second, we must solve a functional problem: to explain how a neural net like the brain links instances to types. I argue that phenomenal binding and functional (...) binding require very different treatments. The puzzle of phenomenal binding rests on a confusion and so can be dissolved. So only functional binding deserves explanation. The general solution to that problem is that information to be bound is arrayed along different dimensions. So sensory coding into separate topographic maps facilitates functional binding and there is no need based on the unity of perception for special mechanisms that bring "back together" information in different maps. (shrink)

Despite its prominent role in cognitive psychology, its relevance for the research of consciousness, and some helpful clarification (e.g., Revonsuo 1999), the binding problem is still surrounded by considerable confusion. In this paper, I first give an informal but systematic overview on the diversity of forms the binding problem can assume, and then attempt to extract, on the basis of "working definitions" of various much-discussed types of binding, a common denominator. I propose that at the (...) heart of the binding problem lies the notion of representing an entity as having a certain property, and discuss several objections that could be raised against the proposed analysis, as well its usefulness and implications.

Given what we know about the segregated nature of the brain and the relative absence of multi-modal association areas in the cortex, how percepts become unified is not clear. However, if we could work out how and where the brain joins together segregated outputs, we would have a start in localizing the neuronal processes that correlate with conscious perceptual experiences. In this essay, I critically examine data relevant for understanding the neurophysiological underpinnings of perception. In particular, I examine the possibility (...) that 40 Hz. oscillatory firing patterns in cortex are important lower-level neuronal events related to perceptual experiences. I suggest that `binding' - understood as a process of hooking together disparate psychological units - reduces to a property inherent in the structure of our brain's firing patterns. However, this reduction may not reflect the firing rates of individual cells, but instead a `higher level' order superimposed on individual cells' activity. (shrink)

ABSTRACTWhile metaphor researchers commonly use the word “mapping” in explanations of various types of figurative language, there is a lack of recognition that the term is itself metaphorical. In fact, the term has two metaphor-based working definitions, the more commonly cited being that relating to mathematical set theory and the less common definition originating in cognitive neuroscience. Perhaps not coincidentally, terminological inconsistencies relating to mapping have led to theoretical problems both for single-domain theories of metonymy and attempts to examine Lakoff’s (...) invariance hypothesis. This article will assert that expressing metonymic connectivity using the neuroscience term “binding” will both eliminate unnecessary theoretical confusion for cognitive linguists and provide common terminology to facilitate productive communication between cognitive linguists and cognitive neuroscientists.

van der Velde's & de Kamps's model encodes complex word-to-word relations in sentences but does not encode the hierarchical constituent structure of sentences, a fundamental property of most accounts of sentence structure. We summarize what is at stake and suggest two ways of incorporating constituency into the model.

Tsuda's article suggests several plausible concepts of neurodynamic representation and processing, with a thoughtful discussion of their neurobiological grounding and formal properties. However, Tsuda's theory leads to a holistic view of brain functions and to the controversial conclusion that the “binding problem” is a pseudo-problem. By contrast, we stress the role of chaotic patterns in solving the binding problem, in terms of flexible temporal coding of visual scenes through graded and intermittent synchrony.

On the one hand, we think that our conscious perceptions are tied to some stage of whatever processing stream we have. On the other hand, we think that our conscious experiences have to resemble the computational states that instantiate them. However, nothing in our alleged stream resembles our experienced perceptions. Hence, a conflict. The question is: How can we go from what we know about neurons, their connections, and firing patterns, to explaining what conscious perceptual experiences are like? No intuitive (...) answer seems plausible. Our perceptual experiences are complex and unified; however, brains divide their processing tasks into small chunks and segregate those smaller pieces across the gray matter. In this essay, I conjecture that what corresponds to our visual perceptions are higher order patterns of bifurcation in an attractor phase space. If I am correct, then the problem of the explanatory gap in philosophy, the binding problem in psychology, and the problem of perception in neuroscience disappear. If the traditional computational perspective is wrong, and sensory processing is not piece-meal, step-wise, and segregated, then there is no need for something in the head to tie things together.

Theories of perception and of memory are closely allied. The binding problem (which considers how bits of perception are reassembled by the brain) leads to neurophysiological subjectivism. This could be outflanked by arguing with Bergson that perceiving consciousness is out in the world. Thus the brain would bind only behavioral “maps.” In turn, consciousness would retain our personal pasts. Such personal (episodic) memories both help us to recognize present objects and to perform creative acts. Memory, although retentive, is (...) also creative. This is important in rethinking biological and evolutionary memory. (shrink)

The paper discusses one of the central problems of contemporary formal semantics — counterexamples to the predictions of the theory of binding (due to N. Chomsky). In particular, the author addresses cases of the so-called coreferential readings of reflexive pronouns which are standardly predicted to receive only the bound reading. The author examines theories of T. Reinhart and I. Heim and suggests an extension ofthe latter theory in order to enable it to account for the aforementioned readings of reflexive (...) pronouns.

van der Velde & de Kamps argue for the importance of considering the binding problem in accounts of human mental representation. However, their proposed solution fails as a complete account because it represents the bindings between roles and their fillers through associations (or connections). In addition, many criticisms leveled by the authors towards synchrony-based bindings models do not hold.

The binding problem is frequently discussed in consciousness research. However, it is by no means clear what the problem is supposed to be and how exactly it relates to consciousness. In the present paper the nature of the binding problem is clarified by distinguishing between different formulations of the problem. Some of them make no mention of consciousness, whereas others are directly related to aspects of phenomenal experience. Certain formulations of the binding (...) class='Hi'>problem are closely connected to the classical philosophical problem of the unity of consciousness and the currently fashionable search for the neural correlates of consciousness. Nonetheless, only a part of the current empirical research on binding is directly relevant to the study of consciousness. The main message of the present paper is that the science of consciousness needs to establish a clear theoretical view of the relation between binding and consciousness and to encourage further empirical work that builds on such a theoretical foundation.

In this article, I discuss how things go with the "Nothing" in the work of Alain Badiou, a topic which is evidently central to his thought, and which has received a great deal of attention in the commentary to date. As this problem is inaccessible outside of Badiou’s deployment of mathematics, I will suggest how accounts of Badiou’s work remain flawed insofar as they evade his mathematical demonstrations, and I attempt to clarify how mathematics operates in his system. I (...) then examine the consequences that such a use of mathematics has for Badiou’s doctrine of the nothing. I conclude with a discussion of some of the difficulties that the nothing continues to pose to Badiou, which have not (yet) been satisfactorily resolved. These difficulties devolve from the problematic of the incessantly doubling void. (shrink)

The capacity for feature binding is typically explained in terms of the attribution model: a perceptual state selects an individual and attributes properties to it (Kahneman & Treisman 1984; Clark 2004; Burge 2010). Thus features are bound together in virtue of being attributed to the same individual. While the attribution model successfully explains some cases of binding in perception, not all binding need be understood as property attribution. This chapter argues that some forms of binding—those involving (...) holistic iconic representations, which bind features outside the limits of attention and object files—don’t fit the attribution model. The chapter then sketches an alternative coordination model of binding that construes icons as complex analog representations. (shrink)

Cognitive functions like perception, memory, language, or consciousness are based on highly parallel and distributed information processing by the brain. One of the major unresolved questions is how information can be integrated and how coherent representational states can be established in the distributed neuronal systems subserving these functions. It has been suggested that this so-called ''binding problem'' may be solved in the temporal domain. The hypothesis is that synchronization of neuronal discharges can serve for the integration of distributed (...) neurons into cell assemblies and that this process may underlie the selection of perceptually and behaviorally relevant information. As we intend to show here, this temporal binding hypothesis has implications for the search of the neural correlate of consciousness. We review experimental results, mainly obtained in the visual system, which support the notion of temporal binding. In particular, we discuss recent experiments on the neural mechanisms of binocular rivalry which suggest that appropriate synchronization among cortical neurons may be one of the necessary conditions for the buildup of perceptual states and awareness of sensory stimuli. (shrink)

The problem of cortical integration is described and various proposed solutions, including grandmother cells, cell assemblies, feed-forward structures, RAAM and synchronization, are reviewed. One method, involving complex attractors, that has received little attention in the literature, is explained and developed. I call this binding through annexation. A simulation study is then presented which suggests ways in which complex attractors could underlie our capacity to reason. The paper ends with a discussion of the efficiency and biological plausibility of the (...) proposals as integration mechanisms for different regions and functions of the brain. (shrink)

Several of the essays in this collection discuss the `binding problem', the problem of explaining in neurophysiological terms how it is that we see the various perceptual qualities of a physical object, such as its shape, colour, location and motion, as features of a single object. The perceived object seems to us a unitary thing, but its sensory properties are diverse and turn out to be processed in different areas of the brain. How then does the brain (...) manage the integration? Readers of the essays in this collection may find themselves suffering from an analogous binding problem about the study of consciousness, though this problem is conceptual rather than perceptual, and here the difficulty is to achieve the integration rather than to understand how an effortless integration is achieved. Consciousness is the ideal topic for inter-disciplinary investigation. It is a central concern of such diverse disciplines as neurophysiology, evolutionary biology, psychology, cognitive science, philosophy and theology, among others, yet none of these disciplines has come close to providing full answers to the central questions that consciousness raises. Inter-disciplinary investigation seems an obvious way forward, but it generates the conceptual binding problem that this collection displays. The standard of the essays is very high, but it is extraordinarily difficult to integrate their content into anything like a single picture. We are all apparently talking about the same phenomenon, the conscious awareness of the world that each of us enjoys first-hand, but it is quite unclear how to see the very different things we say about this phenomenon as part of a single picture, or even as parts of different but compatible pictures. Having raised the binding problem for the inter-disciplinary study of consciousness, I hasten to say that I will not attempt even a partial substantive solution here: that is left as an exercise for the readers of this book.

Human agents draw a variety of inferences effortlessly, spontaneously, and with remarkable efficiency – as though these inferences were a reflexive response of their cognitive apparatus. Furthermore, these inferences are drawn with reference to a large body of background knowledge. This remarkable human ability seems paradoxical given the complexity of reasoning reported by researchers in artificial intelligence. It also poses a challenge for cognitive science and computational neuroscience: How can a system of simple and slow neuronlike elements represent a large (...) body of systemic knowledge and perform a range of inferences with such speed? We describe a computational model that takes a step toward addressing the cognitive science challenge and resolving the artificial intelligence paradox. We show how a connectionist network can encode millions of facts and rules involving n-ary predicates and variables and perform a class of inferences in a few hundred milliseconds. Efficient reasoning requires the rapid representation and propagation of dynamic bindings. Our model (which we refer to as SHRUTI) achieves this by representing (1) dynamic bindings as the synchronous firing of appropriate nodes, (2) rules as interconnection patterns that direct the propagation of rhythmic activity, and (3) long-term facts as temporal pattern-matching subnetworks. The model is consistent with recent neurophysiological evidence that synchronous activity occurs in the brain and may play a representational role in neural information processing. The model also makes specific psychologically significant predictions about the nature of reflexive reasoning. It identifies constraints on the form of rules that may participate in such reasoning and relates the capacity of the working memory underlying reflexive reasoning to biological parameters such as the lowest frequency at which nodes can sustain synchronous oscillations and the coarseness of synchronization.

I argue that Van der Velde and I agree on two fundamental issues surrounding the vision-related binding problem and recent solutions that have been offered: (1) that tagging theories fail to account for object feature binding in visual consciousness and (2) that feedforward-feedback processes in the visual cortical hierarchy play a role in generating a feature-unified object of visual consciousness. Van der Velde develops and discusses an important objection to tagging theories that could help to strengthen my (...) critique of neuronal synchrony (and other tagging theories) and then argues that the cognitive subject makes no explanatory contribution to the unity of an object’s features in visual consciousness. These issues are discussed in turn. By contrast, Van Leeuwen takes a more critical approach to my target article. A two-fold response to Van Leeuwen is offered: first, the root of Van Leeuwen’s perplexity is uncovered and then some specific objections that Van Leeuwen poses to my critique of neuronal synchrony, as a purported solution of the object feature binding problem, are addressed.

Understanding the emergence of a tangible 4-dimensional space-time from a quantum theory of gravity promises to be a tremendously difficult task. This article makes the case that this task may not have to be carried. Space-time as we know it may be fundamental to begin with. I recall the common arguments against this possibility and review a class of recently discovered models bypassing the most serious objection. The generic solution of the measurement problem that is tied to semiclassical gravity (...) as well as the difficulty of the alternative make it a reasonable default option in the absence of decisive experimental evidence.

Names, descriptions, and demonstratives raise well-known logical, ontological, and epistemological problems. Perhaps less well known, amongst philosophers at least, are the ways in which some of these problems not only recur with pronouns but also cross-cut further problems exposed by the study in generative linguistics of morpho-syntactic constraints on interpretation. These problems will be my primary concern here, but I want to address them within a general picture of interpretation that is required if wires are not to be crossed. That (...) picture will be sketched in sections 3 and 4; subsequent sections will focus on pronouns and binding, drawing heavily on what has preceded. (shrink)

The dark matter problem in astrophysics exposes an underappreciated weakness in the evidential warrant for General Relativity (GR). The "dark matter double bind" entails that GR gets no differential evidential support from dynamical phenomena occurring at scales larger than our solar system, as compared to members of a significant class of rival gravitation theories. These rivals are each empirically indistinguishable from GR for phenomena taking place at solar system scales, but make predictions that may differ radically from GR's at (...) larger scales. Thus the typical confidence in the universal applicability of GR is insufficiently warranted in the present evidential context. (shrink)

Parvalbumins (PVs) are acidic, intracellular Ca2+‐binding proteins of low molecular weight. They are associated with several Ca2+‐mediated cellular activities and physiological processes. It has been suggested that PV might function as a “Ca2+ shuttle” transporting Ca2+ from troponin‐C (TnC) to the sarcoplasmic reticulum (SR) Ca2+ pump during muscle relaxation. Thus, PV may contribute to the performance of rapid, phasic movements by accelerating the contraction–relaxation cycle of fast‐twitch muscle fibers. Interestingly, PVs promote the generation of power stroke in fish by (...) speeding up the rate of relaxation and thus provide impetus to attain maximal sustainable speeds. However, immunological monitoring of diverse tissues demonstrated that PVs are also present in non‐muscle cells. The axoplasmic transport and various intracellular secretory mechanisms including the endocrine secretions seem to be controlled by the Ca2+ regulation machinery. Any defect in the Ca2+ handling apparatus may cause several clinical problems; for instance, PV deficiency alters the neuronal activity, a key mechanism leading to epileptic seizures. Moreover, atypical relaxation of the heart results in diastolic dysfunction, which is a major cause of heart failure predominantly among the aged people. PV may offer a unique potential to correct defective relaxation in energetically compromised failing hearts through PV gene transfer. Consequently, PV gene transfer may present a new therapeutic approach to correct cellular disturbances in Ca2+ signaling pathways of diseased organs. Hence, PVs appear to be amazingly useful candidate proteins regulating a variety of cellular functions through action on Ca2+ flux management. (shrink)
