Neural and Psychological Coordination in Social Communication and Interaction

Dynamic, naturalistic study of social interactions in humans is a small but growing literature. Emerging from this work is the theory that social interaction creates a “merged mind” between interlocutors – they come into psychological, behavioral, and neural alignment in order to better predict each other and coordinate as one social unit. However social interaction is diverse, so more work is needed to understand the specific nature of alignment between people in a variety of interactive contexts. In particular, it’s unclear how heterogeneities among members of an interaction impact their ability to align. This work aims to help address this gap by first evaluating and improving ways to collect neuroimaging data in naturalistic, social settings (Chapter 2). Then, empirical research is presented that examines how personal similarity factors impact the extent of alignment during personal disclosure interactions, where one person speaks and the other listens (Chapter 3). Finally, further empirical research investigates different types of alignment that may be present in a dyadic back-and-forth discussion in a joint decision-making paradigm. How this work contributes to a broader understanding of the ways people communicate and work together, and how this research can continue with improved methods, is discussed

Shamanic Cosmology as an Evolutionary Neurocognitive Epistemology

The biological foundation for a shamanic epistemology is indicated by the cross-cultural distribution of a shamanic cosmology derived from knowledge obtained during altered consciousness. These special forms of consciousness involve integrative brain conditions that access ancient ways of knowing, expressive systems which have evolutionary roots in the communicative and social processes involved in animal displays or rituals. These were augmented over the course of hominid evolution into expressive and mimetic activities that provided a basis for significant epistemological expansions of consciousness exemplified in shamanic out-of-body (OBE) experiences. These manifestations of consciousness involved new modes of self and processes of knowing, reflecting selection for expanded symbolic brain processes that enhanced psychological, cognitive integration and extra-personal cognition. Shamanic alterations of consciousness also contributed to experiences of personal spirit essences and encounters with extrapersonal spirit presences that reflected activation of innate brain operators involving self-structures and psyche. The evolution of the hominid capacity for knowing involved new understandings of nature (animism), mind (spirits), self (power animals) and others (gods) that were elicited by shamanic practices and expressed though a shamanistic ideology. These phenomena reflect activation of innate aspects of consciousness, illustrating features of shamanism as a neuroepistemology

Data-driven approaches in the investigation of social perception

The complexity of social perception poses a challenge to traditional approaches to understand its psychological and neurobiological underpinnings. Data-driven methods are particularly well suited to tackling the often high-dimensional nature of stimulus spaces and of neural representations that characterize social perception. Such methods are more exploratory, capitalize on rich and large datasets, and attempt to discover patterns often without strict hypothesis testing. We present four case studies here: behavioural studies on face judgements, two neuroimaging studies of movies, and eyetracking studies in autism. We conclude with suggestions for particular topics that seem ripe for data-driven approaches, as well as caveats and limitations

Acetylcholine neuromodulation in normal and abnormal learning and memory: vigilance control in waking, sleep, autism, amnesia, and Alzheimer's disease

This article provides a unified mechanistic neural explanation of how learning, recognition, and cognition break down during Alzheimer's disease, medial temporal amnesia, and autism. It also clarifies whey there are often sleep disturbances during these disorders. A key mechanism is how acetylcholine modules vigilance control in cortical layer

Neural alpha oscillations index the balance between self-other integration and segregation in real-time joint action

Shared knowledge and interpersonal coordination are prerequisites for most forms of social behavior. Influential approaches to joint action have conceptualized these capacities in relation to the separate constructs of co-representation (knowledge) and self-other entrainment (coordination). Here we investigated how brain mechanisms involved in co-representation and entrainment interact to support joint action. To do so, we used a musical joint action paradigm to show that the neural mechanisms underlying co-representation and self-other entrainment are linked via a process – indexed by EEG alpha oscillations – regulating the balance between self-other integration and segregation in real time. Pairs of pianists performed short musical items while action familiarity and interpersonal (behavioral) synchronization accuracy were manipulated in a factorial design. Action familiarity referred to whether or not pianists had rehearsed the musical material performed by the other beforehand. Interpersonal synchronization was manipulated via congruent or incongruent tempo change instructions that biased performance timing towards the impending, new tempo. It was observed that, when pianists were familiar with each other's parts, millisecond variations in interpersonal synchronized behavior were associated with a modulation of alpha power over right centro-parietal scalp regions. Specifically, high behavioral entrainment was associated with self-other integration, as indexed by alpha suppression. Conversely, low behavioral entrainment encouraged reliance on internal knowledge and thus led to self-other segregation, indexed by alpha enhancement. These findings suggest that alpha oscillations index the processing of information about self and other depending on the compatibility of internal knowledge and external (environmental) events at finely resolved timescales

Therapeutic touch and therapeutic alliance in pediatric care and neonatology: An active inference framework

Therapeutic affective touch has been recognized as essential for survival, nurturing supportive interpersonal interactions, accelerating recovery—including reducing hospitalisations, and promoting overall health and building robust therapeutic alliances. Through the lens of active inference, we present an integrative model, combining therapeutic touch and communication, to achieve biobehavioural synchrony. This model speaks to how the brain develops a generative model required for recovery, developing successful therapeutic alliances, and regulating allostasis within paediatric manual therapy. We apply active inference to explain the neurophysiological and behavioural mechanisms that underwrite the development and maintenance of synchronous relationships through touch. This paper foregrounds the crucial role of therapeutic touch in developing a solid therapeutic alliance, the clinical effectiveness of paediatric care, and triadic synchrony between health care practitioner, caregiver, and infant in a variety of clinical situations. We start by providing a brief overview of the significance and clinical role of touch in the development of social interactions in infants; facilitating a positive therapeutic alliance and restoring homeostasis through touch to allow a more efficient process of allostatic regulation. Moreover, we explain the role of CT tactile afferents in achieving positive clinical outcomes and updating prior beliefs. We then discuss how touch is implemented in treatment sessions to promote cooperative interactions in the clinic and facilitate theory of mind. This underwrites biobehavioural synchrony, epistemic trust, empathy, and the resolution of uncertainty. The ensuing framework is underpinned by a critical application of the active inference framework to the fields of pediatrics and neonatology

Empathy and the Disunity of Vicarious Experiences

Abstract: What makes one individual’s experience vicarious is that it is both similar to, and caused by, another’s psychological state. Vicarious responses are mediated by the observation of another’s goal-directed or expressive action. While the evidence from cognitive neuroscience suggests the ubiquity of vicarious responses to others’ goals, intentions, sensations and emotions, the question is: is the general function of vicarious responses to understand another’s mind? In this paper, I argue for a dual view of the function of vicarious responses: while empathetic responses are other-directed, contagious responses are self-centered.Keywords: Empathy; Vicarious Responses; Action; Self; Otherness.L'empatia e la disunità delle esperienze vicarieRiassunto: Quel che rende un’esperienza individuale un’esperienza vicaria è al contempo il suo essere simile a, ma anche causata da, uno stato psicologico di un altro individuo. Le risposte vicarie sono mediate dall’osservazione dell’azione di un altro nel suo essere diretta al raggiungimento di uno scopo oppure nel suo portare a espressione qualcosa. Se l’evidenza proveniente dalla neuroscienza cognitiva ci autorizza a pensare come ubiquitarie le risposte vicarie nei confronti di obiettivi, intenzioni, sensazioni ed emozioni altrui, la questione che resta aperta è la seguente: la funzione generale delle risposte vicarie è quella di comprendere la mente altrui? Nel presente lavoro intendo proporre un duplice punto di vista sulla funzione delle risposte vicarie: mentre le risposte empatiche sono rivolte verso gli altri, le risposte determinate da esperienze di contagio sono centrate sul sé.Parole chiave: Empatia; Risposte vicarie; Azione; Sé; Alterità

Shamanism in Cross-Cultural Perspective

This article reviews the origins of the concept of the shaman and the principal sources of controversy regarding the existence and nature of shamanism. Confusion regarding the nature of shamanism is clarified with a review of research providing empirical support for a cross-cultural concept of shamans that distinguishes them from related shamanistic healers. The common shamanistic universals involving altered states of consciousness are examined from psychobiological perspectives to illustrate shamanism’s relationships to human nature. Common biological aspects of altered states of consciousness help explain the origins of shamanism while social influences on this aspect of human nature help to explain the diverse manifestations of shamanistic phenomena involving an elicitation of endogenous healing responses

Mental sleep activity and disturbing dreams in the lifespan

Sleep significantly changes across the lifespan, and several studies underline its crucial role in cognitive functioning. Similarly, mental activity during sleep tends to covary with age. This review aims to analyze the characteristics of dreaming and disturbing dreams at dierent age brackets. On the one hand, dreams may be considered an expression of brain maturation and cognitive development, showing relations with memory and visuo-spatial abilities. Some investigations reveal that specific electrophysiological patterns, such as frontal theta oscillations, underlie dreams during sleep, as well as episodic memories in the waking state, both in young and older adults. On the other hand, considering the role of dreaming in emotional processing and regulation, the available literature suggests that mental sleep activity could have a beneficial role when stressful events occur at dierent age ranges. We highlight that nightmares and bad dreams might represent an attempt to cope the adverse events, and the degrees of cognitive-brain maturation could impact on these mechanisms across the lifespan. Future investigations are necessary to clarify these relations. Clinical protocols could be designed to improve cognitive functioning and emotional regulation by modifying the dream contents or the ability to recall/non-recall them
