Christopher Frith is a research professor at the Functional Imaging Laboratory of the Wellcome Department of Imaging Neuroscience at University College, London. He explores, experimentally, using the techniques of functional brain imaging, the relationship between human consciousness and the brain. His research focuses on questions pertaining to perception, attention, control of action, free will, and awareness of our own mental states and those of others. As the following discussion makes clear, Frith investigates brain systems involved in the choice of one action over another and in the understanding of other people. Such investigations are aimed at understanding brain basis of autism and schizophrenia. In his widely cited study of schizophrenia, The Cognitive Neuropsychology of Schizophrenia , Frith argues that many of the positive symptoms of schizophrenia, such as delusions of control, auditory hallucinations, and thought insertion, involve problems of self-monitoring. Patients, in effect, lose track of their own intentions and mistakenly attribute agency for their own actions to someone else. Frith employs models of motor control, involving comparator mechanisms and efference copy, not only to explain delusions that involve movement, but also to develop a neurocognitive explanation of delusional cognition

Theory of mind explanations of how we know other minds are limited in several ways. First, they construe intersubjective relations too narrowly in terms of the specialized cognitive abilities of explaining and predicting another person's mental states and behaviors. Second, they sometimes draw conclusions about secondperson interaction from experiments designed to test third-person observation of another's behavior. As a result, the larger claims that are sometimes made for theory of mind, namely, that theory of mind is our primary and pervasive means for understanding other persons, go beyond both the phenomenological and the scientific evidence. I argue that the interpretation of "primary intersubjectivity" as merely precursory to theory of mind is inadequate. Rather, primary intersubjectivity, understood as a set of embodied practices and capabilities, is not only primary in a developmental sense, but is the primary way we continue to understand others in second-person interactions

Recent significant research in a number of disciplines centers around the concept of the sense of agency. Because many of these studies cut across disciplinary lines there is good reason to seek a clear consensus on what ‘sense of agency’ means. In this paper I indicate some complexities that this consensus might have to deal with. I also highlight an important phenomenological distinction that needs to be considered in any discussion of the sense of agency, regardless of how it gets defined, and I offer some critical comments on some current models tied to the notion that the sense of agency has an ambiguous phenomenology.

Empirical studies of gesture in a subject who has lost proprioception and the sense of touch from the neck down show that specific aspects of gesture remain normal despite abnormal motor processes for instrumental movement. The experiments suggest that gesture, as a linguistic phenomenon, is not reducible to instrumental movement. They also support and extend claims made by Merleau-Ponty concerning the relationship between language and cognition. Gesture, as language, contributes to the accomplishment of thought.

I review the problem of how to define consciousness. I suggest that rather than continuing that debate, we should turn to phenomenological description of experience to discover the common aspects of consciousness. In this way we can say that consciousness is characterized by intentionality, phenomenality, and non-reflective self-awareness. I explore this last characteristic in detail and I argue against higher-order representational theories of consciousness, with reference to blindsight and motor control processes.

Michael Arbib was born in England, grew up in Australia, and studied at MIT where he received his PhD in Mathematics in 1963. He helped to found the Department of Computer and Information Science and the Center for Systems Neuroscience, the Cognitive Science Program, and the Laboratory for Perceptual Robotics at the University of Massachusetts at Amherst. Today he is Fletcher Jones Professor of Computer Science, a Professor of Neuroscience and the Director of the USC Brain Project at the University of Southern California. The title of his first book, Brains, Machines and Mathematics , gives a good indication of his scientific interests. For all his extensive research in these areas, however, Arbib has not ignored philosophical, social, and even theological topics . Central to his work in all of these areas is the concept of schema, and this is one of the topics that we discuss here

Diejenigen, die behaupten, der freie Wille sei Illusion, sind im Unrecht. Sie begründen ihre Behauptung auf einem wissenschaftlichen Beweis, der die falsche Ebene der Deskription des intentionalen Handelns testet. Der freie Wille bezieht sich nicht auf subpersonale neuronale Prozesse, Muskelaktivierung oder grundlegende Körperbewegungen, sondern auf kontextualisierte Handlungen in einem System, das größer ist als viele zeitgenössische Geistesphilosophen, Psychologen und Neurowissenschaftler annehmen. In diesem Artikel beschreibe ich die Art von Intentionalität, die mit der Ausübung des freien Willens einhergeht

Clear statements of both extended and enactive conceptions of cognition can be found in John Dewey and other pragmatists. In this paper I'll argue that we can find resources in the pragmatists to address two ongoing debates: in contrast to recent disagreements between proponents of extended vs enactive cognition, pragmatism supports a more integrative view—an enactive conception of extended cognition, and pragmatist views suggest ways to answer the main objections raised against extended and enactive conceptions—specifically objections focused on constitution versus causal factors, and the mark of the mental

This chapter provides a review of theory of mind approaches to explaining certain dysfunctions of intersubjectivity in pathologies such as autism and schizophrenia. ToM approaches such as theory theory and simulation theory focus on mindreading but fail to explain important aspects of online intersubjective interaction. A phenomenological approach, focusing on embodied interaction, offers an alternative account of intersubjective processes and specific dysfunctions in pathology. Further research is needed on second-person, online interaction to develop this approach as a viable explanation of intersubjective problems in psychopathology.

Hermeneutics is usually defined as the theory and practice of interpretation. As a discipline it involves a long and complex history, starting with concerns about the proper interpretation of literary, sacred, and legal texts. In the twentieth century, hermeneutics broadens to include the idea that humans are, in Charles Taylor’s phrase, ‘self-interpreting animals’ (Taylor, 1985). In contrast to the narrowly prescriptive questions of textual interpretation, philosophical hermeneutics, as developed by thinkers like Heidegger, Gadamer, and Ricoeur, raises questions about the conditions of possibility for human understanding — not how we should interpret or understand something, but what interpretation and understanding are and how they work. For the nineteenth-century philosopher Wilhelm Dilthey, the hermeneutical disciplines were very different from the disciplines of science, including the newly emerging science of psychology. In contrast to psychology, which, in part, attempts to explain the natural behaviour of human animals in causal terms, Dilthey (1926) thinks of the hermeneutical disciplines as attempting to under- stand the behaviour of human persons in terms of their experience and inner motivation. Inner life is not composed of a series of mechanistic starts and stops, but is woven together into a continuity (Zusammenhang) that has a structure, by..

In the past dozen years a number of theoretical models of schizophrenic symptoms have been proposed, often inspired by advances in the cognitive sciences, and especially cognitive neuroscience. Perhaps the most widely cited and influential of these is the neurocognitive model proposed by Christopher Frith (1992). Frith's influence reaches into psychiatry, neuroscience, and even philosophy. The philosopher John Campbell (1999a), for example, has called Frith's model the most parsimonious explanation of how self-ascriptions of thoughts are subject to errors of identification. "On reflection, it also seems that this is not just one possible theory; it is the simplest theory which has any prospect of explaining the sense of agency, and we ought to work from it, introducing complications only as necessary" (1999a, p. 612). Not everyone agrees. In their recent analysis of alien voices and inserted thoughts in schizophrenia, Stephens and Graham (2000) offer a critique of Frith. Their criticism, however, although serious, is neither deep nor extensive. They outline three points. First, Frith fails to provide an adequate account of why a subject who experiences thought insertion would misattribute that thought to some other agent. Second, Frith does not clarify the distinction between thought insertion and thought influence. And third, Frith fails to explain how a subject can claim both that he is thinking the thought and that the thought is someone else's thought (Stephens and Graham..

I argue for a broad education in narratives as a way to address several problems found in moral psychology and social cognition. First, an education in narratives will address a common problem of narrowness or lack of diversity, shared by virtue ethics and the simulation theory of social cognition. Secondly, it also solves the ?starting problem? involved in the simulation approach. These discussions also relate directly to theories of empathy with special significance given to situational empathy

Marc Jeannerod is director of the Institut des Sciences Cognitives in Lyon. His work in neuropsychology focuses on motor action. The idea that there is an essential relationship between bodily movement, consciousness, and cognition is not a new one, but recent advances in the technologies of brain imaging have provided new and detailed support for understanding this relationship. Experimental studies conducted by Jeannerod and his colleagues at Lyon have explored the details of brain activity, not only as we are actively moving, but as we plan to move, as we imagine moving, and as we observe others move. His work also captures important distinctions between pathological and non-pathological experience. In The Cognitive Neuroscience of Action , Jeannerod focussed on object-oriented actions. What happens in the brain and what do we experience when we reach to grasp an object? How do we plan an action of that sort? To what extent does explicit motor imagery contribute to such action? What role does a motor representation or motor schema play in the accomplishment of action? At the very end of that book he raises questions that seem quite different. How is it possible to understand the intentions of others? Precisely what mechanisms allow us to imitate other people's actions? In more recent years much of Jeannerod's work has been in pursuit of these questions about interaction with others, and he has helped to show that there are intimate connections between moving ourselves and understanding others. Jeannerod's work does not lack important implications for a philosophical understanding of human activity. Although in contemporary philosophical debates on consciousness one can still find arguments that simply ignore bodily movement as an important factor in cognition, several recent works have returned to serious consideration of movement and action . In the following interview Jeannerod discusses many issues relevant to the philosophy of mind and action, including concepts of intentionality, movement and consciousness of movement, the role of simulation in understanding others, and the best way to conceptualize brain processes in all of these regards. Importantly, he makes constant reference to the empirical evidence, much of it developed in his own experimental studies

This paper suggests that certain traditional ways of analysing the self start off in situations that are abstract or detached from normal experience, and that the conclusions reached in such approaches are, as a result, inexact or mistaken. The paper raises the question of whether there are more contextualized forms of self- consciousness than those usually appealed to in philosophical or psychological analyses, and whether they can be the basis for a more adequate theoretical approach to the self. First, we develop a distinction between abstract and contextualized actions and intentions by drawing on evidence from studies of rehabilitation after brain damage, and we introduce the notion of intentional attitude. Second, we discuss several interesting conclusions drawn from theoretically and experimentally abstract approaches. These conclusions raise some important issues about both the nature of the self and reflexive consciousness. At the same time they indicate the serious limita- tions concerning what we can claim about self and self-consciousness within such abstract frameworks. Such limitations motivate the question of whether it is possible to capture a sense of self that is more embedded in contextualized actions. Specifically, our concern is to focus on first-person approaches. We identify two forms of self-consciousness, eco- logical self-awareness and embedded reflection, that (1) function within the kinds of contextualized activity we have indicated, and (2) can be the basis for a theoretical account of the self. Both forms of self-consciousness are closely tied to action and promise to provide a less abstract basis for developing a theoretical approach to the self

Is it possible to say that there is no real self if we take a non-Cartesian view of the body? Is it possible to say that an organism can engage in pragmatic action and intersubjective interaction and that the self generated in such activity is not real? This depends on how we define the concept "real". By taking a close look at embodied action, and at Metzinger's concept of embodiment, I want to argue that, on a non-Cartesian concept of reality, the self should be considered something real, and not simply an illusion

In recent years there has been some hard-won but still limited agreement that phenomenology can be of central and positive importance to the cognitive sciences. This realization comes in the wake of dismissive gestures made by philosophers of mind who mistakenly associate phenomenological method with untrained psychological introspection (e.g., Dennett 1991). For very different reasons, resistance is also found on the phenomenological side of this issue. There are many thinkers well versed in the Husserlian tradition who are not willing to consider the validity of a naturalistic science of mind. For them cognitive science is too computational or too reductionistic to be seriously considered as capable of explaining experience or consciousness. In some cases, when phenomenologists have seriously engaged the project of the cognitive sciences, rather than pursing a positive rapprochement with this project, they have been satisfied in drawing critical lines that identify its limitations.On the one hand, such negative attitudes are understandable from the perspective of the Husserlian rejection of naturalism, or from strong emphasis on the transcendental current in phenomenology.

A review of several theories and brain-imaging experiments shows that there is no consensus about how to define the sense of agency. In some cases the sense of agency is construed in terms of bodily movement or motor control, in others it is linked to the intentional aspect of action. For some theorists it is the product of higher-order cognitive processes, for others it is a feature of first-order phenomenal experience. In this article I propose a multiple aspects account of the sense of agency.
