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.

Using theoretical analysis of self-consciousness concept and experimental evidence on the brain default mode network (DMN) that constitutes the neural signature of self-referential processes, we hypothesized that the anterior and posterior subnets comprising the DMN should show differences in their integrity as a function of meditation training. Functional connectivity within DMN and its subnets (measured by operational synchrony) has been measured in ten novice meditators using an electroencephalogram (EEG) recording in a pre-/post-meditation intervention design. We have found that (...) while the whole DMN was clearly suppressed, different subnets of DMN responded differently after 4 months of meditation training: The strength of EEG operational synchrony in the right and left posterior modules of the DMN decreased in resting post-meditation condition compared to a pre-meditation condition, whereas the frontal DMN module on the contrary exhibited an increase in the strength of EEG operational synchrony. These findings combined with published data on functional–anatomic heterogeneity within the DMN and on trait subjective experiences commonly found following meditation allow us to propose that the first-person perspective and the sense of agency (the witnessing observer) are presented by the frontal DMN module, while the posterior modules of the DMN are generally responsible for the experience of the continuity of ‘I’ as embodied and localized within bodily space. Significance of these findings is discussed. (shrink)

Our everyday interactions increasingly involve both embodied face-to-face communication and various forms of mediated and distributed communication such as email, skype, and facebook. In daily face-to-face communications, we are connected in rhythm and synchrony at multiple levels ranging from the moment-by-moment continuity of timed syllables to emergent body and vocal rhythms of pragmatic sense-making. Our human capacity to synchronize with each other may be essential for our survival as social beings. Moving our bodies and voices together in time embodies (...) a potent pragmatic purpose that of being together. In this synchrony of self with other, witnessing and being present become part of each other. There is growing research into how rhythm and synchrony operate in embodied face-to-face interaction and this provides parameters for investigating the relations and differences in how we connect and are socially present in the embodied and distributed settings, and understanding the effect of one setting upon the other. This paper explores the arena of research into rhythm in human interaction, musical and linguistic, with a focus on the movements of body and voice. It draws together salient issues and ideas that would form the basis for a framework of rhythm in embodied interaction. (shrink)

Although several studies propose that the integrity of neuronal assemblies may underlie a phenomenon referred to as awareness, none of the known studies have explicitly investigated dynamics and functional interactions among neuronal assemblies as a function of consciousness expression. In order to address this question EEG operational architectonics analysis (Fingelkurts and Fingelkurts, 2001, 2008) was conducted in patients in minimally conscious (MCS) and vegetative states (VS) to study the dynamics of neuronal assemblies and operational synchrony among them (...) as a function of consciousness expression. We found that in minimally conscious patients and especially in vegetative patients neuronal assemblies got smaller, their life-span shortened and they became highly unstable. Furthermore, we demonstrated that the extent/volume and strength of operational synchrony among neuronal assemblies was smallest or even absent in VS patients, intermediate in MCS patients and highest in healthy fully-conscious subjects. All findings were similarly observed in EEG alpha as well as beta1 and beta2 frequency oscillations. The presented results support the basic tenets of Operational Architectonics theory of brain-mind functioning and suggest that EEG operational architectonics analysis may provide an objective and accurate means of assessing signs of (un)consciousness in patients with severe brain injuries. Therefore this methodological approach may complement the existing “gold standard” of behavioral assessment of this population of challenging patients and inform the diagnostic and treatment decision-making processes.

It has been argued that complex subjective sense of self is linked to the brain default-mode network (DMN). Recent discovery of heterogeneity between distinct subnets (or operational modules - OMs) of the DMN leads to a reconceptualization of its role for the experiential sense of self. Considering the recent proposition that the frontal DMN OM is responsible for the first-person perspective and the sense of agency, while the posterior DMN OMs are linked to the continuity of ‘I’ experience (including (...) autobiographical memories) through embodiment and localization within bodily space, we have tested in this study the hypothesis that heterogeneity in the operational synchrony strength within the frontal DMN OM among patients who are in a vegetative state (VS) could inform about a stable self-consciousness recovery later in the course of disease (up to six years post-injury). Using EEG operational synchrony analysis we have demonstrated that among the three OMs of the DMN only the frontal OM showed important heterogeneity in VS patients as a function of later stable clinical outcome. We also found that the frontal DMN OM was characterized by the process of active uncoupling (stronger in persistent VS) of operations performed by the involved neuronal assemblies. (shrink)

The understanding of the interrelationship between brain and mind remains far from clear. It is well established that the brain's capacity to integrate information from numerous sources forms the basis for cognitive abilities. However, the core unresolved question is how information about the "objective" physical entities of the external world can be integrated, and how unifiedand coherent mental states (or Gestalts) can be established in the internal entities of distributed neuronal systems. The present paper offers a unified methodological and conceptual (...) basis for a possible mechanism of how the transient synchronization of brain operations may construct the unified and relatively stable neural states, which underlie mental states. It was shown that the sequence of metastable spatial EEG mosaics does exist and probably reflects the rapid stabilization periods of the interrelation of large neuron systems. At the EEG level this is reflected in the stabilization of quasi-stationary segments on corresponding channels. Within the introduced framework, physical brain processes and psychological processes are considered as two basic aspects of a single whole informational brain state. The relations between operational process of the brain, mental states and consciousness are discussed. (shrink)

Wearable robots are an emerging form of technology that allow organizations to combine the strength, precision, and performance of machines with the flexibility, intelligence, and problem-solving abilities of human wearers. Active exoskeletons are a type of wearable robot that gives wearers the ability to effortlessly lift up to 200 lbs., as well as perform other types of physically demanding tasks that would be too strenuous for most humans. Synchronization between exoskeleton suits and wearers is one of the most challenging requirements (...) to operate these technologies effectively. In this conceptual paper, we extend interpersonal adaption theory (IAT) to the exoskeleton context and explicate (a) the antecedents that are most likely to shape synchrony in human-exoskeleton interactions, (b) automatic and strategic synchrony as adaptive behaviors in human-exoskeleton interactions, and (c) outcome variables that are especially important in these processes. Lastly, we offer a discussion of key methodological challenges for measuring synchrony in human-exoskeleton interactions and offer a future research agenda for this important area. (shrink)

The target paper of Dr. Feinberg is a testimony to an admirable scholarship and deep thoughtfulness. This paper develops a general theoretical framework of nested hierarchy in the brain that allows production of mind with consciousness. The difference between non-nested and nested hierarchies is the following. In a non-nested hierarchy the entities at higher levels of the hierarchy are physically independent from the entities at lower levels and there is strong constraint of higher upon lower levels. In a nested hierarchy, (...) higher levels are physically composed of lower levels, and there is no central control of the system resulting in weak constraint of higher upon lower levels. (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.

This paper briefly review a current trend in neuroscience aiming to combine neurophysiological and physical concepts in order to understand the emergence of spatio-temporal patterns within brain activity by which brain constructs knowledge from multiple streams of information. The authors further suggest that the meanings, which subjectively are experienced as thoughts or perceptions can best be described objectively as created and carried by large fields of neural activity within the operational architectonics of brain functioning.

Electroencephalogram (EEG) recordings are increasingly used to evaluate patients with disorders of consciousness (DOC) or assess their prognosis outcome in the short-term perspective. However, there is a lack of information concerning the effectiveness of EEG in classifying long-term (many years) outcome in chronic DOC patients. Here we tested whether EEG operational architectonics parameters (geared towards consciousness phenomenon detection rather than neurophysiological processes) could be useful for distinguishing a very long-term (6 years) clinical outcome of DOC patients whose EEGs were (...) registered within 3 months post-injury. The obtained results suggest that EEG recorded at third month after sustaining brain damage, may contain useful information on the long-term outcome of patients in vegetative state: it could discriminate patients who remain in a persistent vegetative state from patients who reach a minimally conscious state or even recover a full consciousness in a long-term perspective (6 years) post-injury. These findings, if confirmed in further studies, may be pivotal for long-term planning of clinical care, rehabilitative programs, medical-legal decisions concerning the patients, and policy makers.

To build a true conscious robot requires that a robot’s “brain” be capable of supporting the phenomenal consciousness as human’s brain enjoys. Operational Architectonics framework through exploration of the temporal structure of information flow and inter-area interactions within the network of functional neuronal populations [by examining topographic sharp transition processes in the scalp electroencephalogram (EEG) on the millisecond scale] reveals and describes the EEG architecture which is analogous to the architecture of the phenomenal world. This suggests that the task (...) of creating the “machine” consciousness would require a machine implementation that can support the kind of hierarchical architecture found in EEG. (shrink)

Based on the finding in novices that four months of meditation training significantly increases frontal default mode network (DMN) module/subnet synchrony while decreasing left and right posterior DMN modules synchrony, the current study tested the prediction whether experienced meditators (those who are practising meditation intensively for several years) had a change in the DMN “trinity” of modules as a baseline trait characteristic and whether this change is in a similar direction as in the novice trainees who practised meditation (...) for only four months. Comparison of functional connectivity within DMN subnets (measured by electroencephalogram operational synchrony in the three separate DMN modules) between five experienced meditators and 10 naïve participants (who were about to start the meditation training) fully support the prediction. Interpretation that links such DMN subnets changes to the three-dimensional components of the experiential selfhood was proposed. (shrink)

Based on previous studies implicating increased functional connectivity within the self-referential brain network in major depressive disorder (MDD), and considering the functional roles of three distinct modules of such brain net (responsible for three-dimensional components of Selfhood) together with the documented abnormalities of self-related processing in MDD, we tested the hypothesis that patients with depression would exhibit increased connectivity within each module of the self-referential brain network and that the strength of these connections would correlate positively with depression severity. Applying (...) the electroencephalogram (EEG) operational synchrony analysis to extract three modules of the self-referential brain network in 12 medication-free depressive outpatients and 10 control subjects we have found an increase in the strength of EEG synchrony within all three modules in depressive patients (though non-significant for the right module). Furthermore, multiple regression analysis that used 3 factors (values of synchrony strength for all three modules) as input indicated that combined increase in the strength of synchrony in all three modules was positively associated with severity of depression. Taken together the findings of this study suggest that depression is primarily associated with hypersynchrony in all three modules of the brain self-referential network (the anterior module been responsible for “witnessing observation and first–person perspective”, the left posterior module been responsible for “reflective agency and narration” and the right posterior module been responsible for “bodily representational-emotional agency”), thus contributing to excessive self-focus, rumination, and body tension.

Background and Objective: Understanding how trauma impacts the self-structure of individuals suffering from the Post-Traumatic Stress Disorder (PTSD) symptoms is a complex matter and despite several attempts to explain the relationship between trauma and the “Self”, this issue still lacks clarity. Therefore, adopting a new theoretical perspective may help understand PTSD deeper and to shed light on the underlying psychophysiological mechanisms. Methods: In this study, we employed the “three-dimensional construct model of the experiential selfhood” where three major components of selfhood (...) (phenomenal first-person agency, embodiment, and reflection/narration) are related to three Operational Modules (OMs) of the self-referential brain network. These modules can be reliably estimated through operational synchrony analysis of the Electroencephalogram (EEG). Six individuals with PTSD symptoms and twenty-nine sex-, age- and demographic- (race, education, marital status) matched healthy controls underwent resting state EEG signal acquisition with the following estimation of the synchrony strength within every OM. Results: Our results indicate that subjects with PTSD symptoms had significantly stronger EEG operational synchrony within anterior and right posterior OMs as well as significantly weaker EEG operational synchrony within left posterior OM compared to healthy controls. Moreover, increased the functional integrity of the anterior OM was positively associated with hyperactivity symptoms, reduced synchrony of the left posterior OM was associated with greater avoidance, and increased right posterior OM integrity was positively correlated with intrusion and mood symptoms. Conclusion: The results are interpreted in light of the triad model of selfhood and its theoretical and clinical implications (including a new treatment approach) are discussed. (shrink)

In this brief overview paper, we analyse information flow in the brain. Although Shannon’s information concept, in its pure algebraic form, has made a number of valuable contributions to neuroscience, information dynamics within the brain is not fully captured by its classical description. These additional dynamics consist of self-organisation, interplay of stability/instability, timing of sequential processing, coordination of multiple sequential streams, circular causality between bottom-up and top-down operations, and information creation. Importantly, all of these processes are dynamic, hierarchically nested and (...) correspond to continuous brain state change, even if the external environment remains constant. This is where metastable coordination comes into play. In a metastable regime of brain functioning, as a result of the simultaneous co-existence of tendencies for independence and cooperation, information is continuously created, preserved for some time and then dissipated through the formation of dynamical and nested spatio-temporal coalitions among simple neuronal assemblies and larger coupled conglomerates of them—so-called delocalised operational modules.

Cortex functional connectivity associated with hypnosis was investigated in a single highly hypnotizable subject in a normal baseline condition and under neutral hypnosis during two sessions separated by a year. After the hypnotic induction, but without further suggestions as compared to the baseline condition, all studied parameters of local and remote functional connectivity were significantly changed. The significant differences between hypnosis and the baseline condition were observable (to different extent) in five studied independent frequency bands (delta, theta, alpha, beta, and (...) gamma). The results were consistent and stable after 1 year. Based on these findings we conclude that alteration in functional connectivity of the brain may be regarded as a neuronal correlate of hypnosis (at least in very highly hypnotizable subjects) in which separate cognitive modules and subsystems may be temporarily incapable of communicating with each other normally.

Recently, a three-dimensional construct model for complex experiential Selfhood has been proposed (Fingelkurts et al., 2016b,c). According to this model, three specific subnets (or modules) of the brain self-referential network (SRN) are responsible for the manifestation of three aspects/features of the subjective sense of Selfhood. Follow up multiple studies established a tight relation between alterations in the functional integrity of the triad of SRN modules and related to them three aspects/features of the sense of self; however, the causality of this (...) relation is yet to be shown. In this article we approached the question of causality by exploring functional integrity within the three SRN modules that are thought to underlie the three phenomenal components of Selfhood while these components were manipulated mentally by experienced meditators in a controlled and independent manner. Participants were requested, in a block-randomised manner, to mentally induce states representing either increased (up-regulation) or decreased (down-regulation) sense of (a) witnessing agency (“Self”), or (b) body representational-emotional agency (“Me”), or (c) reflective/narrative agency (“I”), while their brain activity was recorded by an electroencephalogram (EEG). This EEG-data was complemented by first-person phenomenological reports and standardised questionnaires which focused on subjective contents of three aspects of Selfhood. The results of the study strengthen the case for a direct causative relationship between three phenomenological aspects of Selfhood and related to them three modules of the brain SRN. Furthermore, the putative integrative model of the dynamic interrelations among three modules of the SRN has been proposed. (shrink)

It is the every person's daily phenomenal experience that conscious states represent their contents as occurring now. Following Droege (2009) we could state that consciousness has a peculiar affinity for presence. Some researchers even argue that conscious awareness necessarily demands that mental content is somehow held “frozen” within a discrete progressive present moment. Thus, phenomenal content seems to be minimally conscious if it is integrated into a single and coherent model of reality during a “virtual window” of presence.

Background: Patients in a vegetative state pose problems in diagnosis, prognosis and treatment. Currently, no prognostic markers predict the chance of recovery, which has serious consequences, especially in end-of-life decision-making. Objective: We aimed to assess an objective measurement of prognosis using advanced electroencephalography (EEG). Methods: EEG data (19 channels) were collected in 14 patients who were diagnosed to be persistently vegetative based on repeated clinical evaluations at 3 months following brain damage. EEG structure parameters (amplitude, duration and variability within quasi-stationary (...) segments, as well as the spatial synchrony between such segments and the strength of this synchrony) were used to predict recovery of consciousness 3 months later. Results: The number and strength of cortical functional connections between EEG segments were higher in patients who recovered consciousness (P < .05 – P < .001) compared with those who did not recover. Linear regression analysis confirms that EEG structure parameters are capable of predicting (P = .0025) recovery of consciousness 6 months post-injury, whereas the same analysis failed to significantly predict patient outcome based on aspects of their clinical history alone (P = .629) or conventional EEG spectrum power (P = .473). Conclusions: The result of this preliminary study demonstrates that structural strategy of EEG analysis is better suited for providing prognosis of consciousness recovery than existing methods of clinical assessment and of conventional EEG. Our results may be a starting point for developing reliable prognosticators in patients who are in vegetative state, with the potential to improve their day-to-day management, quality of life, and access to early interventions.

Unresponsive wakefulness syndrome (UWS, previously known as vegetative state) occurs after patients survive a severe brain injury. Patients suffering from UWS have lost awareness of themselves and of the external environment and do not retain any trace of their subjective experience. Current data demonstrate that neuronal functions subtending consciousness are not completely reset in UWS; however, they are reduced below the threshold required to experience consciousness. The critical factor that determines whether patients will recover consciousness is the distance of their (...) neuronal functions from this threshold level. Recovery of consciousness occurs through functional and/or structural changes in the brain, i.e., through neuronal plasticity. Although some of these changes may occur spontaneously, a growing body of evidence indicates that rehabilitative interventions can improve functional outcome by promoting adaptive functional and structural plasticity in the brain, especially if a comprehensive neurophysiological theory of consciousness is followed. In this review we will focus on the pathophysiological mechanisms involved in UWS and on the plastic changes operating on the recovery of consciousness. (shrink)

Everyday joint remembering, from family remembering around the dinner table to team remembering in the operating theatre, relies on the successful interweaving of multiple cognitive, bodily, social and material resources, anchored in specific cultural ecosystems. Such systems for joint remembering in social interactions are composed of processes unfolding over multiple but complementary timescales, which we distinguish for analytic purposes so as better to study their interanimation in practice: (i) faster, lower-level coordination processes of behavioral matching and interactional synchrony occurring (...) at timescale t1; (ii) mid-range collaborative processes which re-evoke past experiences in groups, unfolding at timescale t2; (iii) cooperative processes involved in the transmission of memories over longer periods occurring at timescale t3; and (iv) cultural processes and practices operating within distributed socio-cognitive networks over evolutionary and historical timeframes, unfolding at timescale t4. In this paper we survey studies of how the processes operating across these overlapping and complementary timescales constitute joint remembering in social interactions. We describe coordination, collaboration, cooperation, and culture as complementary aspects of interacting to remember, which we consider as a complex phenomenon unfolding over multiple timescales (t1, t2, t3, t4).

The conclusions drawn by Benjamin Libet from his work with collegues on the timing of somatosensorial conscious experiences has met with a lot of praise and criticism. In this issue we find three examples of the latter. Here I attempt to place the divide between the two opponent camps in a broader perspective by analyzing the question of the relation between physical timing, neural timing, and experiential timing. The nervous system does a sophisticated job of recombining and recoding messages from (...) the sensorial surfaces and if these processes are slighted in a theory, it might become necessary to postulate weird operations, including subjective back-referral. Neuroscientifically inspired theories are of necessity still based on guesses, extrapolations, and philosophically dubious manners of speech. They often assume some neural correlate of consciousness as a part of the nervous system that transforms neural activity in reportable experiences. The majority of neuroscientists appear to assume that the NCC can compare and bind activity patterns only if they arrive simultaneously at the NCC. This leads to a search for synchrony or to theories in terms of the compensation of differences in neural delays . This is the main dimension of the Libet discussion. Examples from vision research, such as “temporal-binding-by-synchrony” and the “flash-lag” effect, are then used to illustrate these reasoning patterns in more detail. Alternatively one could assume symbolic representations of time and space that are not coded in their own dimension . Unless such tags are multiplexed with the quality message , one gets a binding problem for tags. One of the hidden aspects of the discussion between Libet and opponents appears to be the following. Is the NCC smarter than the rest of the nervous system, so that it can solve the problems of local sign and timing on its own, or are these pieces of information coded symbolically early on in the system? A supersmart NCC appears to be the assumption of Libet's camp . The wish to distribute the smartness evenly across all stages of processing in the nervous system appears to motivate the opponents. I argue that there are reasons to side with the latter group. (shrink)

Crowd behaviour challenges our fundamental understanding of social phenomena. Involving complex interactions between multiple temporal and spatial scales of activity, its governing mechanisms defy conventional analysis. Using 1.5 million Twitter messages from the 15M movement in Spain as an example of multitudinous self-organization, we describe the coordination dynamics of the system measuring phase-locking statistics at different frequencies using wavelet transforms, identifying 8 frequency bands of entrained oscillations between 15 geographical nodes. Then we apply maximum entropy inference methods to describe Ising (...) models capturing transient synchrony in our data at each frequency band. The models show that all frequency bands of the system operate near critical points of their parameter space and while fast frequencies present only a few metastable states displaying all-or-none synchronization, slow frequencies present a diversity of metastable states of partial synchronization. Furthermore, describing the state at each frequency band using the energy of the corresponding Ising model, we compute transfer entropy to characterize cross-scale interactions between frequency bands, showing a cascade of upward information flows in which each frequency band influences its contiguous slower bands and downward information flows where slow frequencies modulate distant fast frequencies.

Osteopathy is a person-centred healthcare discipline that emphasizes the body’s structure-function interrelationship—and its self-regulatory mechanisms—to inform a whole-person approach to health and wellbeing. This paper aims to provide a theoretical framework for developing an integrative hypothesis in osteopathy, which is based on the enactivist and active inference accounts. We propose that osteopathic care can be reconceptualised under active inference as a unifying framework. Active inference suggests that action-perception cycles operate to minimize uncertainty and optimize an individual’s internal model of the (...) lived world and, crucially, the consequences of their behaviour. We argue that active inference offers an integrative framework for osteopathy, which can evince the mechanisms underlying dyadic and triadic exchanges and osteopathic care outcomes. We propose that this theoretical framework can underpin osteopathic care across the lifespan, from preterm infants to the elderly and those with persistent pain and other physical symptoms. In situations of chronicity, as an ecological niche, the patient-practitioner dyad provides the osteopath and the patient with a set of affordances, i.e., possibilities for action provided by the environment, that through shared intentionally, can promote adaptations and restoration of productive agency. Through a dyadic therapeutic relationship, as they engage with their ecological niche’s affordances—a structured set of affordances shared by agents—osteopath and patient actively construct a shared sense-making narrative and realise a shared generative model of their relation to the niche. In general, touch plays a critical role in developing a robust therapeutic alliance, mental state alignment, and biobehavioural synchrony between patient and practitioner. However, its role is particularly crucial in the fields of neonatology and paediatrics, where it becomes central in regulating allostasis and restoring homeostasis. We argue that from an active inference standpoint, the dyadic shared ecological niche underwrites a robust therapeutic alliance, which is crucial to the effectiveness of osteopathic care. Considerations and implications of this model—to clinical practice and research, both within- and outside osteopathy—are critically discussed. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 25.2 (2001) 335-346 [Access article in PDF] Aesthetic Incunabula Ellen Dissanayake Incunabula n. pl. (f. L swaddling clothes, cradle): Early stages of development of a thing.Over the past thirty years, developmental psychologists have discovered remarkable cognitive abilities in young infants. Before these investigations, common pediatric wisdom accepted that apart from a few innate "reflexes"--for crying, suckling, clinging, startling--babies were pretty much tabulae rasae for their elders (...) to inscribe as they (and their cultures) decreed. Today, however, it is well established that newborns come into the world with decided preferences and motivations, so that one can speak intelligently of "neonatal" (or even "fetal") psychology. 1The demonstrable existence of inherent psychological capacities in newborns and infants has important implications for twenty-first-century literary theory, which--also over the past thirty years--has operated under the theoretical assumption that all knowledge and experience are mediated by culture and that there is therefore no "natural" psychological or emotional experience. Yet if, as infant psychology confirms, babies in every culture show the same or similar cognitive abilities and preferences and the same or similar motivations and emotional responses, it is necessary to modify the dogmatic assertion that all experience, including literary response, is socially constructed. Rather, adult psychology and experience grow from and build upon inborn motives and preferences. Literary theorists can no longer ignore contemporary knowledge in psychobiology, ethology, and evolutionary psychology that directly pertains to conceptualizing their subject.The innate capacities of newborns predispose them specifically for social and emotional interaction with others, not simply for soliciting [End Page 335] their physical care. For example, newborns prefer human faces to any other sight (high-contrast colors, cartoon characters, cute stuffed animals) and human voices to any other sound (soft music, tinkling bells, The Chipmunks). 2 They can imitate face, mouth, and hand movements and respond appropriately to another person's emotional expressions of sadness, fear, and surprise. 3 At birth, infants can estimate and anticipate intervals of time and temporal sequences and remember these temporal patterns, categorizing them both in time and space and in terms of affect and arousal. 4 By six weeks of age, these perceptual and cognitive abilities of normal infants permit them to engage with adult partners in complex communicative interchanges--the playful behavior that is commonly or colloquially called "babytalk."Babytalk is not the trival or inane pastime that it might superficially seem but, rather, a cradle in which nascent psychosocial capacities can emerge and be developed. Interestingly for literary theory, babytalk achieves these effects through fundamentally aesthetic means. Adult-infant engagements are noteworthy for their use of stylization (formalization or simplification), repetition, exaggeration, and elaboration in visual, vocal, and gestural modalities. I call these "aesthetic incunabula"--that is, sources (or early developmental stages) of the operations used by artists in all media to attract attention and to provoke and manipulate emotional response. The existence of sensitivities to such features in the first months of life suggests that humans are born with natural (innate, universal) predispositions for aesthetic engagement from which cultures and individuals can go on to create their myriad elaborated forms of artistic expression.Although babytalk varies in minor details among individuals and cultures, it can be described in all instances as a multimedia performance. That is, it contains not only "talk" (or the characteristic high-pitched, undulant, breathy, patterned, repetitive vocalizations with pauses called "motherese," "parentese," or "infant-directed speech"). Along with the utterances are peculiarly stereotyped, repetitive, and exaggerated facial expressions (such as widened eyes, uplifted eyebrows, sustained open mouth, and smiles), head movements (e.g., distinct bobs backwards, slow rhythmic nods, movement toward and away from the baby), and gestures (such as touching, stroking, and rhythmic pats) to which infants respond with their own vocal sounds and face and body movements and, in many societies, sustained mutual gaze.Babytalk is not only a performance, but a duet that incorporates both synchrony of behavior and alternation (or turn-taking)--activities that [End Page 336] are made possible by the infant's remarkable inborn sensitivity to temporal sequence and pattern.

We introduce a new version of the perceptual retouch model. This model was used for explaining properties of temporal interaction of successive objects in reaching conscious representation. The new model incorporates two interactive binding operations – binding features for objects and binding the bound feature-objects with a large scale oscillatory system that corresponds to perceptual consciousness. Here, the typical result of masking experiments – second object advantage in conscious perception – is achieved by applying the effects of a common synchronizing (...) oscillator with a delay. This delayed modulation of each of the feature-binding first-order oscillators that represent emerging and decaying neural activities of each of the objects guarantees that the oscillating synchrony of the feature-neurons of the following object is higher than the synchrony of the feature-neurons of the first presented object. Thus we model the fact that the following object dominates the preceding object in conscious perception. We also show the capacity of the model to simulate illusory misbinding of features from different objects. The third qualitative effect, the relative release of the first object from backward masking is achieved by priming the non-specific oscillatory modulation ahead in time. (shrink)

Gould is cited by John Whiteoak and Aline Scott-Maxwell as an "outstanding player who has never ceased to develop as an improviser" and who "as a pianist, records prolifically across a wide musical spectrum."1While the music was jazz, it was freer and fresher than usual. There was striking interaction among the musicians, including facial expressions that reflected genuine ecstasy, and body movement that was naturally "in sync" with the music. I began to ask many questions, including: Is Australia's jazz different from that [End Page 82] in the U.S.? Is Tony Gould's influence as a teacher the reason for the difference? What accounts for the sensation of "freshness" in this music? And why is this musical experience so gripping, both aurally and visually? Serendipitously, I discovered answers through the opportunity to respond to Schmidt's aims of dialogue-of-deconstruction. I shall illustrate how those aims, namely decentralized power and conflict, multiplicity and meaning, and mis-listening may be met in the improvising music ensemble.Decentralized Power and ConflictThe lifeblood of "free jazz" and "free improvisation" ensembles is de-centralized musical interaction, which may be considered a metaphor for dialogue-as-deconstruction. Case in point: the Tony Gould Quartet was an improvising unit with each musician contributing to the musical whole. The air was electric with each musician poised in both the anticipation of what the other might play and in the moment of creation.A recent trend in studies of organizational behavior is on "self-directed" or "self-managed" groups, as identified by Keith R. Sawyer.2 David Borgo3 explains that the characteristics of these "self-organizing systems" or "SOSs" are threefold: they operate without centralized control, they "exhibit both complex and adaptive dynamics," and they are comprised of autonomous individuals who demonstrate a high degree of connectivity. Both authors assert that an ideal SOS is the free improvising ensemble, where musical ideas are allowed to emerge and adapt, and even musical "mistakes" may be manipulated into the context, thus creating new directions in dialogue.However, SOSs have some inherent problems. For example, they are "slow to emerge.... The more complex they are, the longer it may take them to warm up: hierarchical layers have to settle down... and individual(s) have to acquaint themselves with one another."4 Borgo explained that even advanced improvisers often need to pursue a musical idea for a long while for it to achieve coherence. Philip Alperson adds: "As the number of designing intelligences increases, the greater is the difficulty in coordinating all the parts; the twin dangers of cacophony and opacity lurk around the corner."5It seems that "interactional synchrony"6 can develop among musicians who have "good chemistry" after a warm-up period, but those with conflicting personalities, aesthetic dispositions, or musical styles may have a more difficult time of it. When members of the Tony Gould Quartet were asked how they are able to achieve musical unity, they explained that they have played together for many years, they "hang out and drink together" when not on the bandstand, and they trust each other. Even when one of the members feels "out of sorts," their improvisations are respected as authentic expressions. Others' differences are honored, [End Page 83] rather than felt in opposition to one's self.7 Ingrid Monson8 quotes several musicians who use the metaphor of marriage to describe the musical relationship during a peak performance; on the other hand, jealousy, competition, and even hostility on the bandstand are not uncommon and can destroy an ensemble. So, it appears... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Diacritics 29.4 (1999) 58-83 [Access article in PDF] Imagi-Nation: The Imagined Community and the Aesthetics of Mourning Marc Redfield Of the many relics of the Romantic era that continue to shape our (post)modernity, the nation-state surely ranks among the most significant. Two decades ago Benedict Anderson commented that "'the end of the era of nationalism,' so long prophesied, is not remotely in sight" [IC 3], and the intervening years (...) have made it increasingly clear that the developments and processes we summarize as "globalization" operate in mingled synchrony and tension with the political form of the nation-state. 1 That the nation-state should remain the premier vehicle of political and economic legitimation in an era dominated by American imperialism and international capital--forces that, of course, regularly and flagrantly violate the sovereignty of disadvantaged nations--is unsurprising if one accepts the continuing pertinency and power of a Western master-narrative of modernity, according to which the nation represents the emergence of a people into history and prefigures the global achievement of universal human concord. As the proper subject of history, the nation-state can prefigure history's end because, as David Lloyd writes, "the particularism of [nationalism's] contents, potentially in contradiction with the universalism of modernity, is subsumed in the formal congruence between its own narratives of identity, directed at one people, and the narrative of identity that universal history represents for humanity in general" ["Nationalisms" 178]. Lloyd goes on to note that the nation's intermediate status in this narrative--halfway between primitive tribalism and modernity's ever-deferred perpetual peace--accounts for nationalism's irreducibly double association with modernization and atavism. In consequence, the modernist paradigm continues to rule many skeptical or hostile accounts of nationalism, for so long as the nation-state is taken to supersede other political or social formations, the cosmopolitan critique fails to challenge "the fundamental philosophy of universal history that underwrites nationalism's inscription in modernity" ["Nationalisms" 177]. Indeed, both in the corporate media and in mainstream Western political discourse generally, nations and nationalisms are commonly treated as atavistic or progressive depending on the degree to which their behavior harmonizes with globalizing imperatives. That these imperatives emanate quite blatantly from Wall Street in no way seriously troubles the effectiveness of modernity as a narrative paradigm. 2Seeking to discredit universalizing narrative, much cultural criticism in recent years has exchanged cosmopolitanism and the abstract question of "nationalism" for an emphasis [End Page 58] on the contextual construction of national movements or identities. 3 This valuable body of work has sought to recover the particularity of cultural and socioeconomic circumstance, stressed the fundamental role of racism in colonialist contexts, and noted ways in which nationalist movements draw on or unleash forms of resistance that challenge representationalist politics. The pages that follow, however, remain focused on the nationalist fantasy proper to the discourse of modernity. Cultural critique can only profit from knowing as much as possible about the favored turns of the universal-historicist model, particularly since, as Lloyd and others have emphasized, this model is an aesthetic one that grants a world-historical role to "culture." The state, in a tradition that in its main lines runs from Schiller through Hegel and Matthew Arnold and is still very much alive today, represents the community to itself, thereby giving the community form and in a certain sense giving it an ethical imperative and a future: the state represents "our best self" [Arnold 99, passim], "the archetype of a human being" [Schiller 17], because it signifies the formal unification both of the citizen with the community and of the community with universal humanity. Because this unification is ideal rather than actual, it can be projected as the ethical terminus of history (that is, as the ideal of an accomplished modernity). The state's core mission thus becomes pedagogical: its job is to acculturate its subjects into citizens. The production of a docile citizenry thereby obtains an ethical aura and an aesthetic character, insofar as the artwork and the domain of aesthetic or "cultural" experience generally become...

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)

Group dynamics play an important role in the social interactions of both children and adults. A large amount of research has shown that merely being allocated to arbitrarily defined groups can evoke disproportionately positive attitudes toward one’s in-group and negative attitudes toward out-groups, and that these biases emerge in early childhood. This prompts important empirical questions with far-reaching theoretical and applied significance. How robust are these inter-group biases? Can biases be mitigated by behaviors known to bond individuals and groups together? (...) How can bonds be forged across existing group divides? To explore these questions, we examined the bonding effects of interpersonal synchrony on minimally constructed groups in a controlled experiment. In-group and out-group bonding were assessed using questionnaires administered before and after a task in which groups performed movements either synchronously or non-synchronously in a between-participants design. We also developed an implicit behavioral measure, the Island Game, in which physical proximity was used as an indirect measure of interpersonal closeness. Self-report and behavioral measures showed increased bonding between groups after synchronous movement. Bonding with the out-group was significantly higher in the condition in which movements were performed synchronously than when movements were performed non-synchronously between groups. The findings are discussed in terms of their importance for the developmental social psychology of group dynamics as well as their implications for applied intervention programs. (shrink)

Several studies have now documented menstrual synchrony in human females. There is a broad consensus that the phenomenon mainly occurs in women who spend a significant amount of time together, such as close friends and coworkers, and that social contact rather than a similar environment plays an important role in mediating the effect. However, the mechanisms involved and the adaptive function of menstrual synchrony are not understood. There is some evidence that olfactory cues between females might underlie the (...) effect. More research is needed before the precise mechanisms that regulate menstrual synchrony are elucidated. (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.

We present a model for generating a kind of neural synchrony in which the individual spike trains of one neuron or group of neurons closely match the spike trains of another. This kind of neural synchrony has been observed in animals performing auditory, visual and attentional information processing tasks. Our model is realized in a system of functionally identical, refractory spiking neurons. Larger systems with more sophisticated information processing capabilities can be constructed from aggregated instances of the basic (...) network. (shrink)

Expectation of others’ cooperative behavior plays a core role in economic cooperation. However, the dynamic neural substrates of expectation of cooperation are little understood. To fully understand EOC behavior in more natural social interactions, the present study employed functional near-infrared spectroscopy hyperscanning to simultaneously measure pairs of participants’ brain activations in a modified prisoner’s dilemma game. The data analysis revealed the following results. Firstly, under the high incentive condition, team EOC behavior elicited higher interbrain synchrony in the right inferior (...) frontal gyrus than individual EOC behavior. Meanwhile, the IBS in the IFG could predict the relationship between empathy/agreeableness and EOC behavior, and this prediction role was modulated by social environmental cues. These results indicate the involvement of the human mirror neuron system in the EOC behavior and the different neural substrates between team EOC and individual EOC, which also conform with theory that social behavior was affected by internal and external factors. Secondly, female dyads exhibited a higher IBS value of cooperative expectation than male dyads in the team EOC than the individual EOC in the dorsal medial prefrontal cortex, while in the individual EOC stage, the coherence value of female dyads was significantly higher than that of male dyads under the low incentive reward condition in the rIFG. These sex effects thus provide presumptive evidence that females are more sensitive to environmental cues and also suggest that during economic social interaction, females’ EOC behavior depends on more social cognitive abilities. Overall, these results raise intriguing questions for future research on human cooperative behaviors. (shrink)

IntroductionHearing loss has a great impact on the people affected, their close partner and the interaction between both, as oral communication is restricted. Nonverbal communication, which expresses emotions and includes implicit information on interpersonal relationship, has rarely been studied in people with hearing impairment. In psychological settings, non-verbal synchrony of body movements in dyads is a reliable method to study interpersonal relationship.Material and methodsA 10-min social interaction was videorecorded in 39 PHI and their significant others. Nonverbal synchrony, which (...) means the nonverbal behaviors of two interacting persons and verbal interaction were analyzed by computer algorithms and observer ratings. Hearing-related quality of life, coping mechanisms, general psychopathology, quality of relationship, and burden of hearing loss experienced by SOs were assessed using questionnaires.ResultsIn the 39 dyads, true nonverbal synchrony differed from pseudosynchrony [t = 2.41; p = 0.02] with a medium effect size. Gender of PHI had a significant effect on general synchrony and on leading by SOs. Age gap correlated with synchronic movements. Very short duration of hearing impairment was associated with lower nonverbal synchrony in the role of leading by SOs. Feeling of closeness by PHI correlated negatively with the role of leading by SOs and feeling of closeness by SOs was positively associated with leading by PHI. No correlation was detected between nonverbal synchrony and other questionnaires. Burden experienced by the SOs was higher in SOs who reported less closeness.DiscussionA longer hearing impairment leads to more nonverbal leading by SOs compared to PHI with very short duration of hearing loss, possibly because of the long-lasting imbalance in communication. If PHI felt more closeness, SOs led less and vice versa. Burden experienced by SOs negatively correlated with closeness reported by SOs. Use of nonverbal signals and communication might help to improve benefits of auditory rehabilitation for PHI and decrease burden experienced by SOs. (shrink)
