Lange & Dyer misunderstand what is meant by an “entity” and confuse a medium of representation with the content being represented. This leads them to the erroneous conclusion that SHRUTI will run out of phases and that its representation of bindings lacks semantic content. It is argued that the limit on the number of phases suffices, and SHRUTI can be interpreted as using “dynamic signatures” that offer significant advantages over fixed preexisting signatures. Bonatti refers to three levels of commitment to (...) a representational theory of the mind and states that SHRUTI is committed to RTM at levels 1 and 2. He acknowledges that SHRUTI is not committed at level 3, but argues that an extended SHRUTI would have to make such a commitment. We agree that SHRUTI is committed to RTM at level 1 and, in a sense, also at level 2. SHRUTI, however, is not committed to RTM at level 3 and, even though it has been extended in several ways, it has retained its original representational character. (shrink)

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.

Contrary to the assertions made in the target article, temporal synchrony, coupled with an appropriate choice of representational primitives, leads to a functionally adequate and neurally plausible architecture that addresses the massiveness of the binding problem, the problem of 2, the problem of variables, and the transformation of activity-based transient representations of events and situations into structure-based persistent encodings of the same.

Shastri & Ajjanagadde argue convincingly that both structured connectionist networks and parallel dynamic inferencing are necessary for reflexive reasoning - a kind of inferencing and reasoning that occurs rapidly, spontaneously, and without conscious effort, and which seems necessary for everyday tasks such as natural language understanding. As S&A describe, reflexive reasoning requires a solution to thedynamic binding problem, that is, how to encode systematic and abstract knowledge and instantiate it in specific situations to draw appropriate inferences. Although symbolic artificial intelligence (...) systems trivially solve the dynamic binding problem using computers' registers and pointers, it has remained a difficult problem for connectionist systems. S&A's temporal synchrony solution to the dynamic binding problem using synchronous firing of argument units and the entities that are bound to them illustrates one way in which connectionist networks can do thisusing a constrained but important class of long-term knowledge rules. Their structured connectionist solution allows dynamic inferencing to proceed in parallel and therefore has a number of advantages for reflexive reasoning over most other connectionist and symbolic systems.

The purpose of this paper is to address a well-known dilemma for physicalism. If mental properties are type identical to physical properties, then their causal efficacy is secure, but at the cost of ruling out mentality in creatures very different to ourselves. On the other hand, if mental properties are multiply realizable, then all kinds of creatures can instantiate them, but then they seem to be causally redundant. The causal exclusion problem depends on the widely held principle that realized properties (...) inherit their causal powers from their realizers. While this principle holds for functional realization, it fails on a broader notion of realization that permits the realization of complex qualitative properties such as spatial and temporal patterns. Such properties are best seen as dependent powerful qualities, which have their causal roles in virtue of being the qualities they are, and do not inherit powers from their realizers. Recent studies have identified one such property—neural synchrony—as a correlate of consciousness. If synchrony is also partially constitutive of consciousness, then phenomenal properties are both multiply realizable and causally novel. I outline a version of representationalism about consciousness on which this constitution claim holds. (shrink)

BackgroundCoaching is increasingly viewed as a dyadic exchange of verbal and non-verbal interactions driving clients' progress. Yet, little is known about how the trajectory of dyadic interactions plays out in workplace coaching.MethodThis paper provides a multiple-step exploratory investigation of movement synchrony of dyads in workplace coaching. We analyzed a publicly available dataset of 173 video-taped dyads. Specifically, we averaged MS per session/dyad to explore the temporal patterns of MS across the cluster of dyads that completed 10 sessions, and (...) a set of 173 dyadic interactions with a varied number of sessions. Additionally, we linked that pattern to several demographic predictors. The results indicate a differential downward trend of MS.ResultsDemographic factors do not predict best fitting MS curve types, and only client age and coach experience show a small but significant correlation.DiscussionWe provide contextualized interpretations of these findings and propose conceptual considerations and recommendations for future coaching process research and practice.

Theories of binding have recently come into the focus of the consciousness debate. In this review, we discuss the potential relevance of temporal binding mechanisms for sensory awareness. Specifically, we suggest that neural synchrony with a precision in the millisecond range may be crucial for conscious processing, and may be involved in arousal, perceptual integration, attentional selection and working memory. Recent evidence from both animal and human studies demonstrates that specific changes in neuronal synchrony occur during all (...) of these processes and that they are distinguished by the emergence of fast oscillations with frequencies in the gamma-range.

Based on the theoretical analysis of self-consciousness concepts, we hypothesized that the spatio-temporal pattern of functional connectivity within the default-mode network (DMN) should persist unchanged across a variety of different cognitive tasks or acts, thus being task-unrelated. This supposition is in contrast with current understanding that DMN activated when the subjects are resting and deactivated during any attention-demanding cognitive tasks. To test our proposal, we used, in retrospect, the results from our two early studies ([Fingelkurts, 1998] and [Fingelkurts et (...) al., 2003]). In both studies for the majority of experimental trails we indeed found a constellation of operationally synchronized cortical areas (indexed as DMN) that was persistent across all studied experimental conditions in all subjects. Furthermore, we found three major elements comprising this DMN: two symmetrical occipito-parieto-temporal and one frontal spatio-temporal patterns. This new data directly supports the notion that DMN has a specific functional connotation – it provides neurophysiologic basis for self-processing operations, namely first-person perspective taking and an experience of agency.

The shared circuits model (SCM) is a useful explanatory framework that can be applied to interpersonal synchrony by incorporating temporal dynamics. Temporally precise predictive simulations and mirroring enable interpersonal synchrony. When partners' movements are highly synchronous, the self/other distinction can be blurred.

Currently, anomalous lived temporality is not included in the main diagnostic criteria or standard symptom checklists. In this article, we present the Transdiagnostic Assessment of Temporal Experience, a structured interview that can be used by researchers and clinicians without a comprehensive phenomenological background to explore abnormal time experiences in persons with abnormal mental conditions regardless of their diagnosis. When extensive data gathered by this scale are available, it will be possible to delineate well-defined anomalous lived temporality profiles for each (...) psychopathological disorder. This instrument may also prove useful for clinicians by providing a more refined assessment of relevant psychopathological symptoms and an in-depth understanding of the patient’s abnormal behaviour as related to specific types of time experience. In the first part of the article, we provide a brief overview of the phenomenological concept of temporality, including pre-phenomenal and phenomenal time, synthesis, conation and synchronization, and of abnormal time experiences in persons affected by psychopathological conditions. In the following part, we describe the basic structure of the interview that comprises seven categories corresponding to the abnormal features of lived temporality: anomalies of synchrony, of time structure, of implicit time flow, of explicit time flow, and anomalous experiences of the past, the present and the future. The paper also includes a section on administration and scoring of the TATE scale, the complete interview and a Likert table for quantifying the frequency, intensity and interference with daily life of the phenomena explored.

Exposure to delayed sensory feedback changes perceived simultaneity between action and feedback [temporal recalibration ] and even modulates the sense of agency over the feedback. To date, however, it is not clear whether the modulation of SoA by TR is caused by a change in perceptual sensitivity or decision criterion of self-agency. This experimental research aimed to tease apart these two by applying the signal detection theory to the agency judgment over auditory feedback after voluntary action. Participants heard a (...) short sequence of tone pips with equal inter-onset intervals, and they reproduced it by pressing a computer mouse. The delay of each tone pip after the mouse press was manipulated as 80 or 180 ms. Subsequently, the participants reproduced it, in which the delay was fixed at 80 ms and there was a 50% chance that the computer took over the control of the tone pips from the participants. The participants’ task was to discriminate who controlled the tone pips and to judge synchrony between tone pips and mouse presses. Results showed that the modulation of the SoA by the TR is caused by a shift in the decision criterion but not in the perceptual sensitivity of agency. (shrink)

The paper describes tableaux based proof methods for temporal logics of knowledge allowing non-trivial interaction axioms between the modal and temporal components, namely those of synchrony and no learning and synchrony and perfect recall. The interaction axioms allow the description of how knowledge evolves over time and makes reasoning in such logics theoretically more complex. Such logics can be used to specify systems that involve the knowledge of processes or agents and which change over time, for (...) example agent based systems, knowledge games or security protocols. Soundness, completeness and termination results for the tableaux are proved. (shrink)

What does it mean “playing music together”? Is this action guided by cognitive or pre-inferential skills? The aim of this paper is to unveil the different components that are implied in a collective action such as “playing music together”. The idea which will be supported is that embodiment and temporality are the main important structures that guide the subject. In the first part, we will emphasize the centrality of corporeality in the development of self-awareness and intercorporeal understanding. In particular, drawing (...) on Merleau-Ponty’s work, we will argue that the cognitive layer of our consciousness and the pre-inferential one are simply the product of our being embodied. Another central structure for the development of selfhood and intersubjectivity is temporality: as we will show, our selfhood and our attunement with the world can be also described in terms of rhythm, whereby implicit body memory allows for the sedimentation of habits, and synchrony, when my bodily and temporalized self is able to automatically tune in with others. In the second part, we will show how these components are at stake in an action like “playing music together”: attending music therapy sessions with patients who suffer indeed from an (inter)corporeal detachment allowed us to observe the centrality of those components described in the first part of our work, that is, to show how pre-reflective features (such as implicit body memory, intercorporeality, rhythm and synchrony) are necessary for the development of higher social (and cognitive) abilities.In fact, first person reports collected through a qualitative interview applied to patients allow to support the priority of the pre-reflective, affective and (inter)bodily components over the reflective ones.

Temporal epistemic logics are known, from results of Halpern and Vardi, to have a wide range of complexities of the satisfiability problem: from PSPACE, through non-elementary, to highly undecidable. These complexities depend on the choice of some key parameters specifying, inter alia, possible interactions between time and knowledge, such as synchrony and agents' abilities for learning and recall. In this work we develop practically implementable tableau-based decision procedures for deciding satisfiability in single-agent synchronous temporal-epistemic logics with interactions (...) between time and knowledge. We discuss some complications that occur, even in the single-agent case, when interactions between time and knowledge are assumed and show how the method of incremental tableaux can be adapted to work in EXPSPACE, respectively 2EXPTIME, for these logics, thereby also matching the upper bounds obtained for them by Halpern and Vardi.

& How does neuronal activity bring about the interpretation of visual space in terms of objects or complex perceptual events? If they group, simple visual features can bring about the integration of spikes from neurons responding to different features to within a few milliseconds. Considered as a potential solution to the ‘‘binding problem,’’ it is suggested that neuronal synchronization is the glue for binding together different features of the same object. This idea receives some support from correlated- and periodic-stimulus motion (...) paradigms, both of which suggest that the segregation of a figure from ground is a direct result of the temporal correlation of visual signals. One could say that perception of a highly correlated visual.. (shrink)

According to Gustave Guillaume, a linguist endowed with incontestable speculative depth, though misunderstood by the linguists and philosophers of his time and rather ignored in linguistic textbooks, language has a temporal architecture, determined by the articulation of time, which from the present, is projected into the future, while having and maintaining its roots in the past. The present is only the interval between the past and the future. As such, time, however, cannot be represented by way of itself: it (...) requires a representation that can only be made via spatial instruments. Guillaume has the merit of having considered human language in the temporal dimension of thought operations, causing it to become an interpretive paradigm of language itself. This is a paradigm able to give a sufficiently well-founded explanation for a series of linguistic phenomena, otherwise lacking sufficient explanation. The theoretical principles on which Guillaume founds his discourse on comprehension, refer to three aspects in particular: operative time, the central concept of Guillaume’s approach to the problems of language, the reciprocity of the relationship between language and discourse, and the idea of succession in the process of constructing language.

In this article, I compare and contrast the phenomenological ethics of Emmanuel Levinas with that of twentieth-century Japanese philosopher, Kuki Shūzō. In the resulting counterpoint, I put special emphasis on the conception of time espoused by each author. I argue that both go astray by mistakenly basing their ethics on the complete otherness of the other (diachrony) rather than recognizing that both the other (diachrony) and I (synchrony) are originally inseparable in experience before the conceptual separation of “me” and (...) “you.” The fetishization of otherness, which is associated with the feminine in the ethics of both philosophers, leads them to overlook how the details of our everyday concrete experience can provide a guide for action. This paper also explores the two East Asian ethical ideals that Kuki proposes–the Buddhist ideal and the ideal of bushidō, the code of the samurai warrior. In his ethics, Kuki prefers the ethics of bushidō to that of Buddhism. I explain how Kuki’s misunderstanding of Buddhism leads him to this choice, and I explore what he overlooked in Buddhist ethics.

The moral pedagogy in the fairy tales is simple but powerful. It is concentrated in the lesson –according to the message of Aristotle– about the finalism sense of action: it makes the child understand that the human answer is an action with sense. Everything in the fairy tale leads to this perspective. Moreover, it exemplifies MacIntyre’s opinion which says that current people tend to be proto-aristotelian and to understand their own life and the other’s in narrative terms.

In E. Levinas’s phenomenology of time three stages belonging to three different works can be distinguished: Le temps et l’Autre (1947), Totalité et Infini (1961), and Autrément qu’être ou au-delà de l’essence (1974). This paper systematically reconstructs these three periods, displaying the progress..

Four-month-old infants can perceive bimodally speciiied events. They respond to relationships between the optic and acoustic stimulation that carries information about an object. Infants can do this by detecting the temporal synchrony of an object’s sounds and its optically specified impacts. They are sensitive both to the common tempo and to the simultaneity of such sounds and visible impacts. These findings support the view that intermodal perception depends at least in part on the detection of invariant relationships in (...) patterns of light and sound. (shrink)

Humans communicate with different modalities. We offer an account of multi-modal meaning coordination, taking speech-gesture meaning coordination as a prototypical case. We argue that temporal synchrony (plus prosody) does not determine how to coordinate speech meaning and gesture meaning. Challenging cases are asynchrony and broadcasting cases, which are illustrated with empirical data. We propose that a process algebra account satisfies the desiderata. It models gesture and speech as independent but concurrent processes that can communicate flexibly with each other (...) and exchange the same information more than once. The account utilizes the ψ-calculus, allowing for agents, input-output-channels, concurrent processes, and data transport of typed λ-terms. A multi-modal meaning is produced integrating speech meaning and gesture meaning into one semantic package. Two cases of meaning coordination are handled in some detail: the asynchrony between gesture and speech, and the broadcasting of gesture meaning across several dialogue contributions. This account can be generalized to other cases of multi-modal meaning. (shrink)

_dualism_ (consciousness lies outside knowable science), _emergence_ (consciousness arises as a novel property from complex computational dynamics in the brain), and some form of _panpsychism_, _pan-protopsychism, or pan-experientialism_ (essential features or precursors of consciousness are fundamental components of reality which are accessed by brain processes). In addition to 1) the problem of subjective experience, other related enigmatic features of consciousness persist, defying technological and philosophical inroads. These include 2) the “binding problem”—how disparate brain activities give rise to a unified sense (...) of “self” or unified conscious content. Temporal synchrony—brain-wide coherence of neural membrane electrical activities—is often assumed to accomplish binding, but _what_ is being synchronized? What is being coherently bound? Another enigmatic feature is 3) the transition from pre-conscious processes to consciousness itself. Most neuroscientists agree that consciousness is the “tip of an iceberg”, that the vast majority of brain activities is. (shrink)

The United Nations Educational, Scientific and Cultural Organization recently declared transhumance pastoralism as an Intangible Cultural Heritage of Humanity. The notion of heritage seeks to recognize the culture behind the seasonal grazing movements along herding routes, between distant and dissimilar ecosystems. The pastoral families move with their herds from pasturelands used during the winter (winter-lands) to areas pastured during the summer (summer-lands). Whereas this is a key step towards the recognition of the cultural dimension associated to this ancient practice, a (...) relevant feature of transhumance pastoralism is its strong linkage with environmental dynamics. This activity developed in a spatiotemporal and co-evolutionary trajectory, which gave rise to a pastoral territory. A territory is the union or linkage of a meaning with a specific place, that is, the space that is appropriated and valued, both symbolically and instrumentally, by human groups. Hence, the pastoral territory represents the socio-ecological system that integrates a pastoral-based community with the natural environment that it inhabits. We propose a co-evolutionary approach to analyzing some key attributes of transhumant pastoralism, which modulate the socio-ecological interdependence. Based on a study case from Northwest Patagonia, Argentina, we identified and characterized seven attributes: (I) mobility, (II) connectivity, (III) temporal synchrony, (IV) local interdependence, (V) local ecological knowledge, (VI) adaptive capacity legacy, and (VII) mixture of land tenure. We discuss these features as examples that represent keystone socio-ecological attributes for the recognition of transhumant pastoral territories as a biocultural heritage. (shrink)

The neural blackboard architecture is a localist structured connectionist model that employs a novel connection matrix to implement dynamic bindings without requiring propagation of temporal synchrony. Here I note the apparent need for many distinct matrices and the effect this might have for scale-up to semantic processing. I also comment on the authors' initial foray into the symbol grounding problem.
