This ground-breaking book provides the first detailed clinical analysis of the various manifestations of catatonia, shutdown and breakdown in autistic individuals, with a new assessment framework (ACE-S) and guidance on intervention and management strategies using a psycho-ecological approach. Based on Dr Amitta Shah's lifetime of clinical experience in Autism Spectrum Disorders, and her research in collaboration with Dr Lorna Wing, this much needed book will be a valuable resource for professionals, autistic individuals and their families and carers.

Could a single human being ever have multiple conscious minds? Some human beings do. The corpus callosum is a large pathway connecting the two hemispheres of the brain. In the second half of the twentieth century a number of people had this pathway cut through as a treatment for epilepsy. They became colloquially known as split-brain subjects. After the two hemispheres of the brain are cortically separated in this way, they begin to operate unusually independently of each other in the realm of thought, action, and conscious experience, almost as if each hemisphere now had a mind of its own. Philosophical discussion of the split-brain cases has overwhelmingly focused on questions of psychological identity in split-brain subjects, questions like: how many subjects of experience is a split-brain subject? How many intentional agents? How many persons? On the one hand, under experimental conditions, split-brain subjects often act in ways difficult to understand except in terms of each of them having two distinct streams or centers of consciousness. Split-brain subjects thus evoke the duality intuition: that a single split-brain human being is somehow composed of two thinking, experiencing, and acting things. On the other hand, a split-brain subject nonetheless seems like one of us, at the end of the day, rather than like two people sharing one body. In other words, split-brain subjects also evoke the unity intuition: that a split-brain subject is one person. Elizabeth Schechter argues that there are in fact two minds, subjects of experience, and intentional agents inside each split-brain human being: right and left. On the other hand, each split-brain subject is nonetheless one of us. The key to reconciling these two claims is to understand the ways in which each of us is transformed by self-consciousness.

Everyone knows what consciousness is: it is what vanishes when we fall into dreamless sleep and reappears when we wake up or when we dream. However, we become less and less confident when we are called to answer fundamental questions about the relationships between consciousness and the physical world. Why is the cerebral cortex associated with consciousness, but not the liver, the heart, the cerebellum or other neural structures? Why does consciousness fade during deep sleep, while cortical neurons remain active? Can unresponsive patients with an island of active cortex surrounded by widespread damage be conscious? Is an artificial system that outperforms people at driving, recognizing faces and objects, and answering difficult questions conscious? Using the Integrated Information Theory (IIT) as a guiding principle, Sizing up Consciousness explores these questions, taking the reader along a fascinating journey from the cerebral cortex to the cerebellum, from wakefulness to sleep, anesthesia, and coma, supercomputers, octopuses, dolphins, and much more besides. By translating theoretical principles into practical measurements, the book outlines a preliminary attempt to identify a general rule to size up the capacity for consciousness within the human skull and beyond. Sizing up Consciousness is a short, accessible book, spanning neuronal activity to existential considerations and is essential reading for anyone interested in awareness and cognition.

The past two decades have seen a surge of interest in the topic of consciousness, with the result that the research literature has expanded greatly. However, until now, there has been little consensus on just which methods are the most effective for the study of consciousness. As a result, a wide range of experimental paradigms have been employed, sometimes making it difficult to compare and contrast experimental findings. 'Behavioral Methods in Consciousness Research' is the first book of its kind, providing an overview of methods and approaches for studying consciousness. The chapters are written by leading researchers and experts, who describe the methods they actually use in their own studies, along with their pitfalls, problems, and difficulties. For all students and researchers embarking on research in this area - and even seasoned researchers - this book is a valuable source of information in helping them design, perform, and analyze scientifically rigorous experiments.

Articulating a thought can be astoundingly easy. We generally have no trouble expressing complex ideas that we have never considered before, though not always. Articulating a thought can also be extremely hard. Our difficulties in articulating thoughts pervade many aspects of philosophical inquiry, as well as many ordinary situations. While we may overcome some of the challenges through education and practice, we cannot do away with them altogether. And the hardest thoughts to articulate often come to us unbidden: as we neither assemble them from other thoughts nor get them from any source of external information. They can come from us freely and spontaneously, and frequently we articulate them in order to find out what they are. In many cases, we would not bother articulating our thoughts if we already had this knowledge-yet, when we find the right words, we can often instantly tell that they express our thought. How do we manage to recognize the formulations of our thoughts, in the absence of prior knowledge of what we are thinking? And why is it that producing a public language formulation contributes in any way to the deeply private undertaking of coming to know our own thoughts? In Articulating a Thought, Eli Alshanetsky considers how we make our thoughts clear to ourselves in the process of putting them into words and examines the paradox of those difficult cases where we do not already know what we are struggling to articulate.

Consciousness is undoubtedly one of the last remaining scientific mysteries and hence one of the greatest contemporary scientific challenges. How does the brain's activity result in the rich phenomenology that characterizes our waking life? Are animals conscious? Why did consciousness evolve? How does science proceed to answer such questions? Can we define what consciousness is? Can we measure it? Can we use experimental results to further our understanding of disorders of consciousness, such as those seen in schizophrenia, delirium, or altered states of consciousness? These questions are at the heart of contemporary research in the domain. Answering them requires a fundamentally interdisciplinary approach that engages not only philosophers, but also neuroscientists and psychologists in a joint effort to develop novel approaches that reflect both the stunning recent advances in imaging methods as well as the continuing refinement of our concepts of consciousness. In this light, the Oxford Companion to Consciousness is the most complete authoritative survey of contemporary research on consciousness. Five years in the making and including over 250 concise entries written by leaders in the field, the volume covers both fundamental knowledge as well as more recent advances in this rapidly changing domain. Structured as an easy-to-use dictionary and extensively cross-referenced, the Companion offers contributions from philosophy of mind to neuroscience, from experimental psychology to clinical findings, so reflecting the profoundly interdisciplinary nature of the domain. Particular care has been taken to ensure that each of the entries is accessible to the general reader and that the overall volume represents a comprehensive snapshot of the contemporary study of consciousness. The result is a unique compendium that will prove indispensable to anyone interested in consciousness, from beginning students wishing to clarify a concept to professional consciousness researchers looking for the best characterization of a particular phenomenon.

Can consciousness and the human mind be understood and explained in sheerly physical terms? Materialism is a philosophical/scientific theory, according to which the mind is completely physical. This theory has been around for literally thousands of years, but it was always stymied by its inability to explain how exactly mere matter could do the amazing things the mind can do. Beginning in the 1980s, however, a revolution began quietly boiling away in the neurosciences, yielding increasingly detailed theories about how the brain might accomplish consciousness. Nevertheless, a fundamental obstacle remains. Contemporary research techniques seem to still have the scientific observer of the conscious state locked out of the sort of experience the subjects themselves are having. Science can observe, stimulate, and record events in the brain, but can it ever enter the most sacred citadel, the mind? Can it ever observe the most crucial properties of conscious states, the ones we are aware of? If it can't, this creates a problem. If conscious mental states lack a basic feature possessed by all other known physical states, i.e., the capability to be observed or experienced by many people, this give us reason to believe that they are not entirely physical. In this intriguing book, William Hirstein argues that it is indeed possible for one person to directly experience the conscious states of another, by way of what he calls mindmelding. This would involve making just the right connections in two peoples' brains, which he describes in detail. He then follows up the many other consequences of the possibility that what appeared to be a wall of privacy can actually be breached. Drawing on a range of research from neuroscience and psychology, and looking at executive functioning, mirror neuron work, as well as perceptual phenomena such as blind-sight and filling-in, this book presents a highly original new account of consciousness.

Millions of us suffer from addiction, including psychiatrist and recovering alcoholic Carl Erik Fisher. But where does this centuries-old behaviour come from and how should we treat it? As a young doctor, Carl Erik Fisher came face to face with his own addiction crisis, one that nearly cost him everything. Now, in The Urge, he investigates the history of this condition; how we have struggled to define, treat, and control it; and how broader understanding and compassion could change people's lives. The Urge is at once an eye-opening history of ideas, a riveting personal story of addiction and recovery, and a clinician's urgent call for a more expansive, nuanced view of one of society's most intractable challenges.

Hallucinations are a troublesome and distressing symptom for countless patients who suffer from psychiatric or neurological conditions. In recent years, a number of new treatment strategies have been developed to help patients suffering from these symptoms.
This book brings together the work of leading experts in this area, to provide a practical guide to the assessment, evaluation, and treatment of hallucinations. It includes a range of interventions, including: Pharmacological, Transcranial Magnetic Stimulation, Cognitive Behavioural Therapy, Hallucinations focused Integrative Therapy (HIT), normalizing techniques, coping strategies, self-help approaches, Acceptance and Commitment Therapy, Attention Training Technique, Competitive Memory Training, appraisal-based cognitive therapy, and cognitive therapy for command hallucinations. As well as providing practical advice, the chapters also contain overviews of the respective areas of research, including references to the evidence base for each intervention - highlighting those interventions in need of more empirical support. Each chapter describes how to evaluate and treat the patient, often using clinical vignettes or case studies to illustrate the treatment process.
The book will be a valuable guide for psychiatrists, clinical psychologists, and counsellors, increasingly required to help patients suffering from these distressing symptoms.

The term 'Implicit Learning' refers to the way in which knowledge of fairly complex, patterned material can be acquired without any conscious effort to learn it and with little to no awareness of what has been learned. Over the past fifty years, Implict Learning has became a vigorously researched area in the social sciences. In The Cognitive Unconscious, Arthur S. Reber and Rhianon Allen bring together several dozen experts from social science and neuroscience to present a broad overview of the exploration of the cognitive unconscious. Each chapter delves deeper into a subject that has become an interdisciplinary domain of research to which contributions have been made by sociologists, neuroscientists, evolutionary biologists, linguists, social and organizational psychologists, and sport psychologists, amongst many others. The book shows that unconscious, implicit cognitive processes play a role in virtually everything interesting that human beings do. As the contributors demonstrate, the implicit and explicit elements of cognition form a rich and complex interactive framework that make up who we are. With contributions from over thirty distinguished authors from nine different countries, The Cognitive Unconscious gives a balanced and thorough overview of where the field is today, over a half-century since the first experiments were run.

Blindsight is an unusual condition where the sufferer can respond to visual stimuli, while lacking any conscious feeling of having seen the stimuli. It occurs after a particular form of brain injury.
The first edition of Blindsight, by one of the pioneers in the field - Lawrence Weiskrantz, reported studies of a patient with this condition. It was an important, much cited publication. In the past twenty years, further work has been done in this area, and this new edition brings the book up to date. Retaining the original text, but adding a substantial new chapter and colour illustrations, the first section of the book summarizes findings on DB since the last published account in 1986. The second part includes information on other new research that has occurred since the last edition. As well as giving an account of research over a number of years into a particular case of blindsight, it provides a discussion of the historical and neurological background, a review of cases reported by other investigators, and a number of theoretical and practical issues and implications.
The book will be valuable for cognitive psychologists and cognitive neuroscientists, as well as philosophers of mind.

In recent years consciousness has become a significant area of study in the cognitive sciences. The Frontiers of Consciousness is a major interdisciplinary exploration of consciousness. The book stems from the Chichele lectures held at All Souls College in Oxford, and features contributions from a 'who's who' of authorities from both philosophy and psychology. The result is a truly interdisciplinary volume, which tackles some of the biggest and most impenetrable problems in consciousness.
The book includes chapters considering the apparent explanatory gap between science and consciousness, our conscious experience of emotions such as fear, and of willed actions by ourselves and others. It looks at subjective differences between two ways in which visual information guides behaviour, and scientific investigation of consciousness in non-human animals. It looks at the challenges that the mind-brain relation presents for clinical practice as well as for theories of consciousness. The book draws on leading research from philosophy, experimental psychology, functional imaging of the brain, neuropsychology, neuroscience, and clinical neurology.
Distinctive in its accessibility, authority, and its depth of coverage, Frontiers of Consciousness will be a groundbreaking and influential addition to the consciousness literature.

This book is a compilation of nine short books written between 2007 and 2021, in the ninth and tenth decades of the author's life. It contains his spiritual philosophy expressed in simple language accessible to all. The book tells of what the author has come to believe after a lifetime of seeking for the meaning of life, and how one should live that life at its optimum level. He explains that this cannot be proved: it is ultimately not susceptible to the usual scientific methods, for it lies in a different realm of reality which has to be experienced inwardly. However, its main tenets lie behind world religions and go back to mankind`s earliest thinkings and feelings. Believe it or not as you will, suggests the author. All he can say is that it has sustained him throughout his life and has made that life harmonious and joyous. The teachings of which he speaks are often referred to as the Ancient Wisdom. He first came across them at the age of twenty-five when he met a man who was well versed in that ancient wisdom which is to be found woven throughout major religions, philosophies and mystical teachings. This man was Eugene Halliday, who, the author says, was said to be one of the great spirits of the modern age. The phrase he used to describe the ultimate result of these teachings was 'Reflexive Self-Consciousness'. This, the author explains, was the same message taught by those of old, although expressed by his mentor Halliday in more modern terms. A wise but modest man, the author says that he is no academic or scholar or learned man - adding, with gentle humour, that it is written that an academic is an ass with a load of books on his back. He writes for the average person - of any age - who has no time left to think on these things but who may like to know more. He writes for this person - for he is such a one himself, he says. It is this which makes his story and his accumulated wisdom both inspiring and accessible.

'Mindblowing' Michael Pollan Why do we know so much more about the cosmos than our own consciousness? Are there limits to the scientific method? Why do we assume that only science, mathematics and technology reveal truth? The Flip shows us what happens when we realise that consciousness is fundamental to the cosmos and not some random evolutionary accident or surface cognitive illusion; that everything is alive, connected, and 'one'. We meet the people who have made this visionary, intuitive leap towards new forms of knowledge: Mark Twain's prophetic dreams, Marie Curie's seances, Einstein's cosmically attuned mind. But these forms of knowledge are not archaic; indeed, they are essential in a universe that has evolved specifically to be understandable by the consciousnesses we inhabit. The Flip peels back the layers of our beliefs about the world to reveal a visionary, new way of understanding ourselves and everything around us, with huge repercussions for how we live our lives. After all, once we have flipped, we understand that the cosmos is not just human. The human is also cosmic.

Can computers be conscious?
Is our universe real of a simulation?
Is the mind a unique quality of human beings?

As technological breakthroughs in AI continue to advance, topics like this have become part of the daily news cycle. But what does it all mean and what is at stake for the human race?

When Tim Parks came across a radical new theory of consciousness he set off on a quest to discover more about this fascinating topic and also let him to observe his own experience with immense attention.

Out of My Head tells the gripping, highly personal, often surprisingly funny, story of a paradigm shift. It frames complex metaphysical considerations and technical laboratory experiments in terms we can all understand. Above all, it invites us to see space, time, colour and smell, sounds and sensations in an entirely new way. The world will feel more real after reading it.

Over the past three decades, the challenge that conscious experience poses to physicalism--the widely held view that the universe is a completely physical system--has provoked a growing debate in philosophy of mind studies and given rise to a great deal of literature on the subject. Ideal for courses in consciousness and the philosophy of mind, Consciousness and The Mind-Body Problem: A Reader presents thirty-three classic and contemporary readings, organized into five sections that cover the major issues in this debate: the challenge for physicalism, physicalist responses, alternative responses, the significance of ignorance, and mental causation. Edited by Torin Alter and Robert J. Howell, the volume features work from such leading figures as Karen Bennett, Ned Block, David J. Chalmers, Frank Jackson, Colin McGinn, David Papineau, and many others. It is enhanced by a thorough general introduction by the editors, which explains the hard problem of consciousness--the question of how any physical phenomenon could give rise to conscious experience.The introduction also provides historical and conceptual background and explains how the consciousness/mind-body problem is related to such theories as the identity theory, dualism, and functionalism. In addition, accessible introductions outline the themes and readings contained in each section.

Although psychoanalytic criticism has long been established as a practice in its own right, dialogue between the clinical and aesthetic has so far been perfunctory. This innovative book sets out to show in detail that there is a poetics of the unconscious equally at work in both domains, the critical potential of which has been missed by both sides.

In Part I, Wright focuses on the discoveries of Freudian psychoanalysis and demonstrates how the fundamental fantasies emerging in clinical practice are uncannily shared by works of art. This devotion of the unconscious to its phantasmic history is illustrated with examples from Freud, surrealist painting and Julia Kristeva's work on melancholia. In Part II, the focus shifts to Lacan's view of language as a means of agitating the unconscious of the reader. Part III takes examples from the rhetoric of clinical discourse, showing how practitioners are aware of a range of poetic meanings for both patient and analyst. The three parts demonstrate that all language is inescapably figural, as it betrays the operations of desire and fantasy in both aesthetic and clinical discourse.

This book is suitable for second- and third-year undergraduate students and above in literature and literary theory, feminism and gender studies, and psychoanalysis.

Philosophical work on the mind flowed in two streams through the 20th century: phenomenology and analytic philosophy. The phenomenological tradition began with Brentano and was developed by such great European philosophers as Husserl, Heidegger, Sartre, and Merleau-Ponty. As the century advanced, Anglophone philosophers increasingly developed their own distinct styles and methods of studying the mind, and a gulf seemed to open up between the two traditions. This volume aims to bring them together again, by demonstrating how work in phenomenology may lead to significant progress on problems central to current analytic research, and how analytical philosophy of mind may shed light on phenomenological concerns. Leading figures from both traditions contribute specially written essays on such central topics as consciousness, intentionality, perception, action, self-knowledge, temporal awareness, and mental content. Phenomenology and Philosophy of Mind demonstrates that these different approaches to the mind should not stand in opposition to each other, but can be mutually illuminating.

THE DEFINITIVE GUIDE TO CANNABIS AND YOUR HEALTH Underpinned by his two-year research trial in partnership with the Royal College of Psychiatrists, involving up to 20,000 patients, which will create Europe's largest body of evidence on the plant's medicinal qualities - Professor David Nutt and his team of scientists will break the mould on the way we use Cannabis for our health in the future. In David's first ground-breaking book on the subject, he will cover its impact of all areas of the body and the brain and its effective use for treatment of illness from chronic pain, epilepsy, multiple sclerosis and PTSD, to anxiety and depression. This is the essential knowledge that cuts through the noise and give us evidence-based information that will change people's lives.
