Higher order intentionality tasks are cognitively more demanding

A central assumption that underpins much of the discussion of the role played by social cognition in brain evolution is that social cognition is unusually cognitively demanding. This assumption has never been tested. Here, we use a task in which participants read stories and then answered questions about the stories in a behavioural experiment (39 participants) and an fMRI experiment (17 participants) to show that mentalising requires more time for responses than factual memory of a matched complexity and also that higher orders of mentalising are disproportionately more demanding and require the recruitment of more neurons in brain regions known to be associated with theory of mind, including insula, posterior STS, temporal pole and cerebellum. These results have significant implications both for models of brain function and for models of brain evolution

Disruption to the core self in autism, and its care

This article offers a neuroscientific explanation of the experience of autism as a disruption to the embodied experience of the Core Self. It recognizes human experience is integrative by nature. Attending to the insights of Penelope Dunbar (Pum), who has lived with autism for decades, we explore an affective neuroscience understanding of autistic experience as a disruption to embodiment and coherence of the Core Self, and how to work creatively with its impulses for health and personal development. Pum describes her autistic disruptions to the intra-personal coherence of her basic states of being, moving-with-feeling in self-awareness, and how this disturbance to her internal subjective coherence of mind challenges her capacity to self-regulate arousal, and communicate with others. By examination of the source of her problems in childhood and ways of working with them, Pum has clarified fundamental elements in the development of her capacity to regulate self-care in creative efforts that facilitate both affective embodiment and sensory-motor coherence in growth of understanding in her mind and body. With her advice, we explore how current neurobiological insights in autism as a disruption to the regulation of affective embodiment and sensory-motor integration leads to new recommendations for therapeutic care to relieve autistic distress and restricted modes of being. Although particular to her circumstances and cultivated habits of autistic expression, this analysis offers insight into the fundamental nature of autism, and ways of positive working with one’s autism for creative gains

Alteración del self nuclear en el autismo y su cuidado

Este artículo ofrece una explicación neurocientífica de la experiencia del autismo como una alteración de la experiencia encarnada del self nuclear. Reconoce que la experiencia humana es integradora por naturaleza. Prestando atención a las observaciones de Penelope Dunbar (Pum), que ha vivido con autismo durante décadas, exploramos una comprensión desde la neurociencia de la afectividad de la experiencia autista como una alteración de la encarnación y la coherencia del self nuclear, y cómo trabajar creativamente sus impulsos para el desarrollo personal y de la salud. Pum describe sus alteraciones autistas en la coherencia intrapersonal de sus estados básicos, en la integración de movimiento con sentimiento en la autoconciencia y cómo esta alteración en su coherencia mental subjetiva interna desafía a su capacidad de autorregular la excitación y de comunicarse con los demás. Mediante el examen de la fuente de sus problemas en la infancia y su forma de trabajar con ellos, Pum ha aclarado elementos fundamentales para el desarrollo de su capacidad para regular el autocuidado en esfuerzos creativos que facilitan tanto la encarnación afectiva como la coherencia sensoriomotora en el crecimiento de la comprensión de su mente y su cuerpo. Con su consejo, exploramos cómo los hallazgos neurobiológicos actuales sobre el autismo como una alteración en la regulación de la encarnación afectiva y la integración sensoriomotora dan lugar a nuevas recomendaciones para el cuidado terapéutico orientado al alivio de la angustia autista y de las limitaciones en el modo de ser. Aunque es específico de sus circunstancias y de sus hábitos de expresión autista, este análisis ofrece una visión de la naturaleza fundamental del autismo, y modos de trabajar de forma positiva con el autismo propio para obtener beneficios creativos

Rhythmic Relating : Bidirectional support for social timing in autism therapies

We propose Rhythmic Relating for autism: a system of supports for friends, therapists, parents, and educators; a system which aims to augment bidirectional communication and complement existing therapeutic approaches. We begin by summarizing the developmental significance of social timing and the social-motor-synchrony challenges observed in early autism. Meta-analyses conclude the early primacy of such challenges, yet cite the lack of focused therapies. We identify core relational parameters in support of social-motor-synchrony and systematize these using the communicative musicality constructs: pulse; quality; and narrative. Rhythmic Relating aims to augment the clarity, contiguity, and pulse-beat of spontaneous behavior by recruiting rhythmic supports (cues, accents, turbulence) and relatable vitality; facilitating the predictive flow and just-ahead-in-time planning needed for good-enough social timing. From here, we describe possibilities for playful therapeutic interaction, small-step co-regulation, and layered sensorimotor integration. Lastly, we include several clinical case examples demonstrating the use of Rhythmic Relating within four different therapeutic approaches (Dance Movement Therapy, Improvisational Music Therapy, Play Therapy, and Musical Interaction Therapy). These clinical case examples are introduced here and several more are included in the Supplementary Material (Examples of Rhythmic Relating in Practice). A suite of pilot intervention studies is proposed to assess the efficacy of combining Rhythmic Relating with different therapeutic approaches in playful work with individuals with autism. Further experimental hypotheses are outlined, designed to clarify the significance of certain key features of the Rhythmic Relating approach

Disruption to embodiment in autism, and its repair

This paper offers a neuroscientific explanation of life with autism which recognises that human behaviour and experience is by nature both personal and interpersonal. With a focus on insights of Penelope Dunbar (Pum) who has lived with autism for decades, we explore an affective neuroscience understanding of autistic experience and how to work creatively with its impulses for health and personal development. Pum describes her autistic disruptions to the intra-personal coherence of her basic states of being, moving-with-feeling in self-awareness, and how this disturbance to her internal subjective coherence of mind challenges her capacity to self-regulate arousal, and communicate with others. By examination of the source of her problems in childhood and ways of working with them, Pum has clarified fundamental elements in the development of her capacity to regulate self-care in creative efforts that facilitate both affective embodiment and sensory-motor coherence in growth of understanding in her mind and body. With her advice we explore how current neurobiological insights in autism as a disruption to the regulation of affective embodiment and sensory-motor integration leads to new recommendations for therapeutic care to relieve autistic distress and restricted modes of being. Although particular to her circumstances and cultivated habits of autistic expression, this analysis offers insight into the fundamental nature of autism, and ways of positive working with one’s autistic nature for creative gains

Ventromedial prefrontal volume predicts understanding of others and social network size

Cognitive abilities such as Theory of Mind (ToM), and more generally mentalizing competences, are central to human sociality. Neuroimaging has associated these abilities with specific brain regions including temporo-parietal junction, superior temporal sulcus, frontal pole, and ventromedial prefrontal cortex. Previous studies have shown both that mentalizing competence, indexed as the ability to correctly understand others' belief states, is associated with social network size and that social group size is correlated with frontal lobe volume across primate species (the social brain hypothesis). Given this, we predicted that both mentalizing competences and the number of social relationships a person can maintain simultaneously will be a function of gray matter volume in these regions associated with conventional Theory of Mind. We used voxel-based morphometry of Magnetic Resonance Images (MRIs) to test this hypothesis in humans. Specifically, we regressed individuals' mentalizing competences and social network sizes against gray matter volume. This revealed that gray matter volume in bilateral posterior frontal pole and left temporoparietal junction and superior temporal sucus varies parametrically with mentalizing competence. Furthermore, gray matter volume in the medial orbitofrontal cortex and the ventral portion of medial frontal gyrus, varied parametrically with both mentalizing competence and social network size, demonstrating a shared neural basis for these very different facets of sociality. These findings provide the first fine-grained anatomical support for the social brain hypothesis. As such, they have important implications for our understanding of the constraints limiting social cognition and social network size in humans, as well as for our understanding of how such abilities evolved across primates

Orbital prefrontal cortex volume correlates with social cognitive competence

Intentionality, or Theory of Mind, is the ability to explain and predict the behaviour of others by attributing to them intentions and mental states and is hypothesised to be one of several social cognitive mechanisms which have impacted upon brain size evolution. Though the brain activity associated with processing this type of information has been studied extensively, the neuroanatomical correlates of these abilities, e.g. whether subjects who perform better have greater volume of associated brain regions, remain to be investigated. Because social abilities of this type appear to have evolved relatively recently, and because the prefrontal cortex (PFC) was the last brain region to develop both phylogenetically and ontogenetically, we hypothesised a relationship between PFC volume and intentional competence. To test this, we estimated the volume of four regional prefrontal subfields in each cerebral hemisphere, in 40 healthy adult humans by applying stereological methods on T(1)-weighted magnetic resonance images. Our results reveal a significant linear relationship between intentionality score and volume of orbital PFC (p=0.01). Since this region is known to be involved in the processing of social information our findings support the hypothesis that brain size evolution is, at least in part, the result of social cognitive mechanisms supporting social cohesion
