Book Description
CT afferents are receptors in mammalian hairy skin that fire action potentials when the skin is touched lightly which makes them particularly important in affective touch. Traditionally neuroscientific research has focused on more discriminative and haptic properties of touch that are mediated by large myelinated afferents and the coding properties and functional organization of unmyelinated CT afferents have been studied much less. The proposed volume will draw together existing knowledge in this nascent field. Separate sections will address (1) how we can measure affective touch, (2) CT structure and physiology, (3) CT processing, (4) the contribution of CTs to sexual behavior, (5) clinical relevance, (6) commercial relevance, and (7) future research considerations.​

Book Description
Stimulation of sensory nerves can give rise to powerful affective experiences. Noxious stimuli can give rise to pain, an unpleasant experience which, in turn, causes suffering and constitutes a major societal burden. Touch, on the other hand, can feel pleasant and plays an important role in social relationships and well-being. Slow, gentle stroking of the skin in particular has been shown to activate C-tactile (CT) afferents, which are thought to signal affective and socially relevant aspects of touch. However, little is known about how pain and affective touch influence everyday decision making. In Paper I, we investigated the effect of acute physical pain on risk taking and intertemporal choice. Participants (n = 109) performed a series of economic decision-making tasks, once while experiencing acute thermal pain and once in a no-pain control condition. Results indicated that pain increased risk taking for monetary gains but not for equivalent losses, and increased impatience. In Paper II, we investigated the effect of affective touch on betrayal aversion, altruism, and risk taking. Participants (n = 120) performed a series of economic decision-making tasks, once while being stroked on the forearm at CT-optimal speed using a soft painter’s brush and once in a no-touch control condition. Results indicated no effect of affective touch on any of the outcome measures. In Paper III, we investigated how the ability to affect an upcoming painful event via voluntary action influences cortical processing of ongoing somatosensory stimulation. fMRI data was collected from 30 participants while they performed a task that involved pressing a response button to reduce the duration of upcoming thermal stimuli. Whole-brain analyses revealed no significant task-related effects in brain regions typically involved in pain, except activation in a cluster in anterior cingulate cortex (ACC) was greater when upcoming stimulation was painful than when it was nonpainful. However, region-of-interest analyses in anterior insula (AI) and midcingulate cortex (MCC) indicated that the noxious nature of the upcoming stimulation, as well as the ability to affect it, influenced processing of ongoing stimulation in both of these regions. Activation in MCC, but not AI, also correlated with response times. Taken together, these studies contribute to the broader understanding of everyday decision making, and of how affective experiences such as pain and touch shape everyday decisions and behaviors. Stimulering av nervfibrer i huden kan ge upphov till starka känsloupplevelser. Skadliga eller potentiellt skadliga stimuli kan ge upphov till smärta, en obehaglig upplevelse som i sin tur orsakar lidande och har stora socioekonomiska konsekvenser. Beröring, å andra sidan, kan upplevas som behagligt och är en viktig del av sociala relationer. Förhållandevis lite kunskap finns dock om hur smärta och beröring påverkar vardagligt beslutsfattande. Blir vi otåliga av att uppleva smärta? Tar vi fler risker? Gör beröring oss snällare och mer tillitsfulla? I denna avhandling presenteras tre studier som försöker svara på denna typ av frågor. I den första studien fick deltagarna smärtsam värmestimulering samtidigt som de fattade beslut om pengar. Besluten involverade t.ex. att välja mellan en säker vinst på 50 kr eller att singla slant om att vinna 100 kr. Resultaten visade att smärta ökade risktagande för vinster, men inte för motsvarande förluster. Deltagare som upplevde smärta var även mer otåliga, dvs. de föredrog i större utsträckning snabba belöningar. I den andra studien fick deltagarna beröring med en mjuk pensel samtidigt som de fattade beslut. Lätt, smekande beröring aktiverar en särskild typ av nervfibrer, som tros signalera affektiva och socialt relevanta aspekter av beröring. Beröring ökar även utsöndringen av hormonet oxytocin, som sägs öka känslan av tillit till andra människor, även om de vetenskapliga bevisen för detta är motstridiga. Resultaten av studien visade ingen effekt av beröring på beslutsfattande. I den tredje studien undersöktes hjärnans aktivitet vid smärtsam stimulering. Vi vet sedan tidigare att hjärnan inte bara reagerar på det som händer just nu, utan att den även förbereder inför vad som kan komma att hända i framtiden. Deltagarna fick smärtsam eller icke-smärtsam värmestimulering samtidigt som de utförde en uppgift som innebar att de skulle trycka på en knapp för att förkorta en kommande värmestimulering. Resultaten visade att hjärnans bearbetning av pågående stimulering påverkades av huruvida nästkommande stimulering var smärtsam eller inte och huruvida den gick att påverka. Sammantaget bidrar dessa studier till en ökad förståelse av hur människor fattar beslut och hur upplevelser som smärta och beröring påverkar vardagligt beslutfattande och beteende. Smärta har en stark koppling till beteende, eftersom vi snabbt måste kunna agera för att undvika skada. Beröring, däremot, upplevs på olika sätt beroende på den sociala kontexten, vilket troligtvis också påverkar beröringens effekt på beteende.

Book Description
The cognitive ability to think about other people's psychological states is known as `mindreading'. This Element critiques assumptions that have been formative in shaping philosophical theories of mindreading: that mindreading is ubiquitous, underpinning the vast majority of our social interactions; and that its primary goal is to provide predictions and explanations of other people's behaviour. It begins with an overview of key positions and empirical literature in the debate. It then introduces and motivates the pluralist turn in this literature, which challenges the core assumptions of the traditional views. The second part of the Element uses case studies to further motivate the pluralist framework, and to advocate the pluralist approach as the best way to progress our understanding of social cognitive phenomena.

Book Description
An At-Home Guide to Children’s Sensory and Behavioral Problems gives a new perspective on sensory and behavior problems, one that sees those behaviors as stemming from a child’s immature sensory nervous system and regulation difficulties. This book offers an effective at-home intervention, the Qigong Sensory Treatment, that enlists a parent's attuned touch to address often overlooked sensory issues that underlie ‘problem’ behaviors and works to organize those sensory experiences to foster connection and the capacity for self-regulation. It introduces the reader to a new and clinically useful model to understand sensory development, the Early Childhood Self-regulatory Milestones which are critical to the emotional and behavioral health and regulation for all children. With clear step-by-step instructions, diagrams, and links to online instructional videos, it teaches parents how to successfully implement the daily QST hands-on routine. Unique to the treatment model is how it guides and focuses parents to easily recognize, interpret and respond to their child's shifting non-verbal body and behavioral responses and cues. An extensive workbook section navigates parents through a year-long process of learning and implementing QST at home. Weekly letters include those written by the authors, parents who share their own personal experiences with the routine and by QST Master Trainers who offer their years of experience and helpful tips. The 52 letters are timed to anticipate and answer typical questions or stumbling blocks that parents commonly encounter at key points, guiding them to success with their child’s sensory and behavior difficulties while making for happier and less-stressful times with their child. This guide will be indispensable to parents and clinicians looking to understand and more effectively work with their child’s developmental difficulties.

Book Description
There is a growing interest in embodied approaches to psychotherapy internationally. This volume focuses on the respective focal professions of dance movement psychotherapy (DMP) and body psychotherapy (BP), addressing the psychotherapeutic need for healing throughout the lifespan. Within embodied clinical approaches, the therapist and client collaborate to discover how the body and movement can be used to strengthen positive relational skills, attending to the client's immediate and long-term needs through assessment, formulation, treatment and evaluation. Both DMP and BP are based upon the capacity and authority of the body and non-verbal communication to support and heal patients with diverse conditions, including trauma, unexplained bodily symptoms and other psychological distress, and to develop the clients’ emotional and relational capacities by listening to their bodies for integration and wellbeing. In The Routledge International Handbook of Embodied Perspectives in Psychotherapy, world leaders in the field contribute their expertise to showcase contemporary psychotherapeutic practice. They share perspectives from multiple models that have been developed throughout the world, providing information on theoretical advances and clinical practice, as well as discourse on the processes and therapeutic techniques employed individually and in groups. Presented in three parts, the book covers underpinning embodiment concepts, potentials of dance movement psychotherapy and of body psychotherapy, each of which is introduced with a scene-setting piece to allow the reader to easily engage with the content. With a strong focus on cross- and interdisciplinary perspectives, readers will find a wide compilation of embodied approaches to psychotherapy, allowing them to deepen and further their conceptualization and support best practice. This unique handbook will be of particular interest to clinical practitioners in the fields of body psychotherapy and dance movement psychotherapy as well as professionals from psychology, medicine, social work, counselling/psychotherapy and occupational therapy, and to those from related fields who are in search of information on the basic therapeutic principles and practice of body and movement psychotherapies and seeking to further their knowledge and understanding of the discipline. It is also an essential reference for academics and students of embodied psychotherapy, embodied cognitive science and clinical professions.

Book Description
Touch is one of the fundamental media for interpersonal communication. Over recent decades, scientific efforts have been devoted to establishing the significance of touch, particularly affective touch, in the treatment and prevention of mental disorders and clarifying the underlying mechanisms of touch and massage therapy. This book contributes to this rapidly expanding area of research and gives new insights on recent clinical and experimental findings. A strong plea is made by the editors for well-designed clinical studies which require very special methodologies. A broad spectrum of various touch therapies are already available at present. Modern treatment and prevention of mental disorders should go beyond the pharmacological and psychotherapeutic approaches and should make use of the beneficial effects of touch therapies with the additional benefit of a very small risk of adverse outcomes.
