What is the role of conscious visual experience in the control and guidance of human behaviour? According to some recent treatments, the role is surprisingly indirect. Conscious visual experience, on these accounts, serves the formation of plans and the selection of action types and targets, while the control of 'online' visually guided action proceeds via a quasi-independent non-conscious route. In response to such claims, critics such as (Wallhagen [2007], pp. 539-61) have suggested that the notions (...) of control and guidance invoked are unacceptably vague, and that that the image of 'zombie systems' guiding action fails to take account of the possibility that there is genuine but unconceptualized, unnoticed, and/or unreportable experience taking place and guiding or controlling the actions. I address both sets of concerns. I try to show that refining and clarifying the key notions of control and guidance leaves the original argument intact, as does the appeal to unconceptualized, unnoticed, or unreportable experiences. The exercise serves, however, to highlight an important complex of considerations concerning the relations between control, agency, and experience. Better understanding these relations is, I suggest, an important source of insights concerning the nature of phenomenal experience. (shrink)

Despite the compelling subjective experience of executive self-control, we argue that ‘consciousness’ contains no top-down control processes. We propose that ‘consciousness’ involves no executive, causal or controlling relationship with any of the familiar psychological processes conventionally attributed to it. In our view all psychological processing and psychological products are non-conscious. In particular, we argue that all ‘contents of consciousness’ are generated by and within non-conscious brain systems in the form of a continuous self-referential personal narrative that (...) is not directed or influenced in any way by the ‘experience of consciousness’. This continuously updated personal narrative arises from selective ‘internal broadcasting’ of outputs from non-conscious executive systems that have access to all forms of cognitive processing, sensory information and motor control. The personal narrative provides information for storage in autobiographical memory and is underpinned by constructs of self and agency, also created in non-conscious systems. The experience of consciousness, is seen as a passive accompaniment to the non-conscious processes of internal broadcasting and the creation of the personal narrative. In this sense personal awareness is analogous to the rainbow which accompanies physical processes in the atmosphere but exerts no influence over them. Though at an individual level it is an end-product created by non-conscious executive systems, the personal narrative serves the powerful evolutionary function of enabling individuals to communicate (externally broadcast) the contents of internal broadcasting. This in turn allows the recipients to generate potentially adaptive strategies, such as predicting the behavior of others and underlies the development of social and cultural structures, that promote species survival. Consequently, it is the capacity to communicate to others the contents of the personal narrative that confers an evolutionary advantage – not the experience of consciousness (personal awareness) itself.

In a recent study of a patient in a persistent vegetative state, [Owen, A. M., Coleman, M. R., Boly, M., Davis, M. H., Laureys, S., & Pickard, J. D. . Detecting awareness in the vegetative state. Science, 313, 1402] claimed that they had demonstrated the presence of consciousness in this patient. This bold conclusion was based on the isomorphy between brain activity in this patient and a set of conscious control subjects, obtained in various imagery tasks. However, establishing (...) consciousness in unresponsive patients is fraught with methodological and conceptual difficulties. The aim of this paper is to demonstrate that the current debate surrounding consciousness in VS patients has parallels in the artificial intelligence debate as to whether machines can think. Basically, used a method analogous to the Turing test to reveal the presence of consciousness, whereas their adversaries adopted a line of reasoning akin to Searle’s Chinese room argument. Highlighting the correspondence between these two debates can help to clarify the issues surrounding consciousness in non-communicative agents. (shrink)

The power to exercise control is a crucial feature of agency. Necessarily, if S cannot exercise some degree of control over anything - any state of affairs, event, process, object, or whatever - S is not an agent. If S is not an agent, S cannot act intentionally, responsibly, or rationally, nor can S possess or exercise free will. In my dissertation I reflect on the nature of control, and on the roles consciousness plays in its exercise. (...) I first consider the fragmented state of philosophical and empirical work on control. I argue that a mature philosophy of agency stands in need of a detailed personal-level account of control, and I begin by explicating a notion I call intentional control. On this explication, an agent J exercises intentional control in service of an intention X to the degree that behavior of J's for which X plays a (non-deviant) causal role approximates the representational content of X. With this explication in hand, I offer analyses of theoretically salient points along a degreed spectrum (covering, e.g., the exercise of minimal, successful, and perfect intentional control). Next, I develop an account of the degrees of intentional control's possession. This involves elucidation of ingredients of intentional control, i.e. those features of agents and environments that constitute an agent's causal potency and skill. It turns out that an agent's possession of control regarding an intention is intimately tied to her ability to repeatedly execute that intention across some specified (hypothetical) set of scenarios. Finally, I discuss a number of potentially fruitful applications of the account. In chapter three I confront a strong intuition, persistent in both philosophy and cognitive science, that consciousness is somehow intimately involved in the exercise of control. In this connection recent empirical work indicates the causal powers of consciousness remain poorly understood. I argue that Functional Agnosticism - the view that any claim regarding a function of consciousness for behavior is currently underdetermined by the data - is the wisest position on the causal powers of consciousness. Recognition of this unsatisfying state of affairs motivates reflection on what might enable progress beyond it. I argue that establishing a causal function for consciousness is facilitated by clarity on several issues. First, what is the sense of consciousness at issue? I isolate state consciousness, discuss the potential relevance of various types of conscious states, and distinguish between ambitious and modest approaches to the causal powers of state consciousness. In short, ambitious approaches seek to understand the causal contributions of a conscious mental state in virtue of the fact that the state is conscious; modest approaches seek to understand the causal contributions of conscious mental states, full stop. I argue that for various theoretical purposes, both approaches can be useful. Second, what is the sense of control at issue? I argue that for many important theoretical purposes, intentional control is the relevant sense. Finally, I illustrate the usefulness of clarity on these issues by examining recent work on the roles of conscious and unconscious vision for action. This work suggests that some important subset of our overt action is controlled by non-conscious processes. I apply insights developed earlier, noting common mistakes made in this literature, and highlighting important empirical possibilities these mistakes obscure. In later chapters I develop a novel account of conscious control. In chapter four I develop a central part of the account, which involves a view on the intentional structure of conscious trying. The leading view entails that conscious trying possesses a descriptive (or thetic) structure. Based on relevant empirical work concerning deafferented and paralyzed patients, I argue for the view that conscious trying is (at least) partially constituted by directive (or telic) structure. Finally, I argue that the exercise of conscious control is best understood as an exercise of intentional control for which the experience of trying plays a constitutive role. After presenting arguments for this view and defending the view against objections, I discuss the importance of conscious control for a mature philosophy of mind and agency. (shrink)

Cognitive effort is thought to be familiar in everyday life, ubiquitous across multiple variations of task and circumstance, and integral to cost/benefit computations that are themselves central to the proper functioning of cognitive control. In particular, cognitive effort is thought to be closely related to the assessment of cognitive control’s costs. I argue here that the construct of cognitive effort, as it is deployed in cognitive psychology and neuroscience, is problematically unclear. The result is that talk of cognitive (...) effort may paper over significant disagreement regarding the nature of cognitive effort, and its key functions for cognitive control. I highlight key points of disagreement, and several open questions regarding what causes cognitive effort, what cognitive effort represents, cognitive effort’s relationship to action, and cognitive effort’s relationship to consciousness. I also suggest that pluralism about cognitive effort – that cognitive effort may manifest as a range of intentional or non-intentional actions the function of which is to promote greater success at paradigmatic cognitive control tasks – may be a fruitful and irenic way to conceive of cognitive effort. Finally, I suggest that recent trends in work on cognitive control suggests that we might fruitfully conceive of cognitive effort as one key node in a complex network of mental value, and that studying this complex network may illuminate the nature of cognitive control, and the role of consciousness in cognitive control’s proper functioning.

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.

Until a few years ago, Cognitive Science was firmly wedded to the notion that cognition must be explained in terms of the computational manipulation of internal representations or symbols. Although many people still believe this, the consensus is no longer solid. Whether it is truly threatened by connectionism is, perhaps, controversial, but there are yet more radical approaches that explicitly reject it. Advocates of "embodied" or "situated" approaches to cognition (e.g., Smith, 1991; Varela _et al_ , 1991, Clancey, 1997) argue (...) that thought cannot be understood as entirely internal. Furthermore, it is argued that autonomous robots can be designed to behave more intelligently if representationalist programming techniques are avoided (Brooks, 1991), and that the way our brains control our behavior is better understood in terms of chaos and dynamical systems theory rather than as any sort computation (e.g., Freeman & Skarda, 1990; Van Gelder & Port, 1995; Van Gelder, 1995; Garson, 1996).

In everyday life we take it for granted that we have conscious control of some of our actions and that the part of us that exercises control is the conscious mind. Psychosomatic medicine also assumes that the conscious mind can affect body states, and this is supported by evidence that the use of imagery, hypnosis, biofeedback and other 'mental interventions' can be therapeutic in a variety of medical conditions. However, there is no accepted theory of (...) mind/body interaction and this has had a detrimental effect on the acceptance of mental causation in science, philosophy and in many areas of clinical practice. Biomedical accounts typically translate the effects of mind into the effects of brain functioning, for example, explaining mind/body interactions in terms of the interconnections and reciprocal control of cortical, neuroendocrine, autonomic and immune systems. While such accounts are instructive, they are implicitly reductionist, and beg the question of how conscious experiences could have bodily effects. On the other hand, non-reductionist accounts have to cope with three problems: (1) The physical world appears causally closed, which would seem to leave no room for conscious intervention. (2) One is not conscious of one's own brain/body processing, so how could there be conscious control of such processing? (3) Conscious experiences appear to come too late to causally affect the processes to which they most obviously relate. This paper suggests a way of understanding mental causation that resolves these problems. It also suggests that 'conscious mental control' needs to be partly understood in terms of the voluntary operations of the preconscious mind, and that this allows an account of biological determinism that is compatible with experienced free will.

It is natural to assume that the fine-grained and highly accurate spatial information present in visual experience is often used to guide our bodily actions. Yet this assumption has been challenged by proponents of the Two Visual Systems Hypothesis , according to which visuomotor programming is the responsibility of a “zombie” processing stream whose sources of bottom-up spatial information are entirely non-conscious . In many formulations of TVSH, the role of conscious vision in action is limited to “recognizing (...) objects, selecting targets for action, and determining what kinds of action, broadly speaking, to perform” . Our aim in this study is to show that the available evidence not only fails to support this dichotomous view but actually reveals a significant role for conscious vision in motor programming, especially for actions that require deliberate attention.

This chapter examines what constitutes an “action” and then focuses on simple actions that provide insight into the complex overt and covert processes required to generate them. It considers the contrast between non‐conscious, automatic actions and conscious, controlled ones and analyses the components of controlled actions that are accessible or inaccessible to consciousness. On the basis of experimental and clinical evidence the chapter then develops a model of the neurophysiological processes involved in action recognition and concludes with an (...) evaluation of conscious agency being, in some respects, “an illusion”.

This is the fourth of four online Companions to Velmans, M. (ed.) (2018) Consciousness (Critical Concepts in Psychology), a 4-volume collection of Major Works on Consciousness commissioned by Routledge, London. -/- The Companion (and Volume) begins with a review of mental influences on states of the body and brain (psychogenesis), which are often thought of as theoretically problematic for conventional materialist theories of mind. The evidence is nevertheless extensive, for example in psychosomatic illnesses and studies of the physiological consequences of (...) meditation, imagery, biofeedback and hypnosis. Such effects are also central to developments in psychoneuroimmunology and studies of placebos, dealing not only with how to control for such effects in clinical trials, but with how such effects operate, and how to harness them for the benefit of patients. The Companion then surveys altered states of consciousness, including the conditions for their emergence, their adaptive as well as maladaptive potential, and the influences of culture on how these are understood. The analysis deepens with reviews of the major ways in which consciousness can be usefully transformed, starting with the burgeoning literature on the nature and effects of meditation practices, including their effects on neural dynamics and the varied ways in which they have, in recent years, been incorporated into a range of psychological therapies, focusing particularly on mindfulness and its potential consequences for psychological health. The survey then turns to mystical experiences, which, of all the positive altered states of consciousness, are perhaps the most extraordinary and transformative. Reported over millennia and recognized by William James to combine ineffability with a noetic quality, their generation, effects and interpretation have, once more, become the subject of research. In this connection, we also review the resurgent interest in the use of drugs in the transformation of consciousness focusing particularly on recent research on the clinical and neurophysiological effects of major psychedelics such as psilocybin and LSD. It will be apparent that the four Volumes of this Collection cover a vast range of phenomena that cannot comfortably be accommodated into a materialist, reductionist worldview, and so this Companion (and the entire collection) concludes with a diverse sample of non-reductive, integrative theories that offer unifying ways of understanding consciousness, drawing on information theory, neuropsychology, psychodynamics, physics, psychology, parapsychology, and philosophy. -/- As with the other Companions to these Volumes there are many links to background resources (marked in pink) and to the selected readings themselves (marked in blue). -/- .

IntroductionAlthough the topic of consciousness is both mysterious and controversial, psychedelic drugs are popularly believed to provide unique insights into the nature of consciousness despite a lack of empirical evidence.MethodsThis study addresses the question of whether psychedelics change the attribution of consciousness to a range of living and non-living entities. A survey was conducted in 1,606 respondents who endorsed a belief changing psychedelic experience.ResultsParticipants rated their attributions of consciousness to a range of living and non-living entities before and after their (...) psychedelic experience. Superstitious beliefs and belief in freewill were also assessed. From before the experience to after, there were large increases in attribution of consciousness to various entities including non-human primates, quadrupeds, insects, fungi, plants, inanimate natural objects, and inanimate manmade objects. Higher ratings of mystical experience were associated with greater increases in the attribution of consciousness. Moreover, the increased attributions of consciousness did not decrease in those who completed the survey years after the psychedelic experience. In contrast to attributions of consciousness, beliefs in freewill and superstitions did not change. Notably, all findings were similar when restricted to individuals reporting on their first psychedelic experience.DiscussionThis study demonstrates that, among people who reported belief-changing psychedelic experiences, attribution of consciousness to various entities increases. Future prospective psychedelic drug administration studies that control for expectancies are needed. (shrink)

Traditionally, what we are conscious of in self-consciousness is something non-corporeal. But anti-Cartesian philosophers argue that the self is as much corporeal as it is mental. Because we have the sense of proprioception, a kind of body awareness, we are immediately aware of ourselves as bodies in physical space. In this debate the case histories of patients who have lost their sense of proprioception are clearly relevant. These patients do retain an awareness of themselves as corporeal beings, although they (...) hardly feel their bodies. They can initiate movements, and with the help of visual feedback learn to control them. It is shown that the traditional view of the self as immaterial is not supported by these cases. But the argument against this view has to be amended. It relies too much on bodily sensations, and misses the importance of active self-movement. (shrink)

In daily life we take it for granted that our minds have conscious control of our actions, at least for most of the time. But many scientists and philosophers deny that this is really the case, because there is no generally accepted theory of how the mind interacts with the body. Max Velmans presents a non-reductive solution to the problem, in which ‘conscious mental control’ includes ‘voluntary’ operations of the preconscious mind. On this account, biological determinism (...) is compatible with experienced free will. Velmans’ theory is put to the test by nine critics: Ron Chrisley, Todd Feinberg, Jeffrey Gray, John Kihlstrom, Sam Rakover, Ramakrishna Rao, Aaron Sloman, Steve Torrance andRobert Van Gulick, followed by Velmans' reply.

Journal of Mind and Behavior 28 no. 2 , pp. 135-156. The self-prompting theory of consciousness holds that conscious perceptual experience occurs when non-routine perceptual data prompt the activation of a plan in an executive control system that monitors perceptual input. On the other hand, routine, non-conscious perception merely provides data about the world, which indicatively describes the world correctly or incorrectly. Perceptual experience instead involves data that are about the perceiver, not the world. Their function is (...) that of imperatively prompting the perceiver herself to do something (hence. (shrink)

Until comparatively recently, say the middle of the last century, spinal cord injury was fatal as pressure sores and other infections took their toll. Those with severe brain injuries, unable to move or even communicate, fared even worse; without movement or feeding such patients were nursed until nature took its course. Over the last few decades medical and nursing advances have enabled some of these vegetative patients to survive for considerable time, provoking, at times, ethical and legal dilemmas. Though they (...) survived, without overt behaviour or clear communication their carers were frequently unsure how much residual function remained. Now real progress is occurring in this area thanks to the application of neuro-scientific methods by some outstanding groups of workers. Subjects with severe brain injury may begin in complete, unresponsive coma but then ‘lighten’ to one of three categories. In vegetative state (VS), patients are apparently awake but without evidence of voluntary behaviour and have no apparent awareness of self or environment, whilst in minimally conscious state (MCS) patients have some behaviour beyond the reflex but are not able to communicate effectively. These conditions usually result from widespread brain damage at either or both cortical and subcortical levels due to injury or anoxia, though they can also be seen in end stage neurological conditions like Alzheimer’s. In locked in syndrome (LIS), patients ‘awake’ from coma, usually due to stroke, aware of their surroundings and their situation but unable to speak or move, beyond eye lid control and eye movement. For many, LIS will be recognised from Bauby’s extraordinary account in ‘The Diving Bell and the Butterfly,’ though, incidentally, it was presaged in Samuel Beckett’s novella ‘The Unnameable.’ LIS reflects a profound disconnection between brain and body, except for the upper cranial nerves involved in eyelid movement. The overriding question is how much awareness these patients have.. (shrink)

According to behavioural theories deriving from pragmatism, gestalt psychology, existentialism, and ecopsychology, knowledge about the world is gained by intentional action followed by learning. In terms of the neurodynamics described here, if the intending of an act comes to awareness through reafference, it is perceived as a cause. If the consequences of an act come to awareness through proprioception and exteroception, they are perceived as an effect. A sequence of such states of awareness comprises consciousness, which can grow in complexity (...) to include self-awareness. Intentional acts do not require awareness, whereas voluntary acts require self-awareness. Awareness of the action/perception cycle provides the cognitive metaphor of linear causality as an agency. Humans apply this metaphor to objects and events in the world to predict and control them, and to assign social responsibility. Thus, linear causality is the bedrock of technology and social contracts. Complex material systems with distributed non-linear feedback, such as brains and their neural and behavioural activities, cannot be explained by linear causality. They can be said to operate by circular causality without agency. The nature of self-control is described by breaking the circle into a forward limb, the intentional self, and a feedback limb, awareness of the self and its actions. The two limbs are realized through hierarchically stratified kinds of neural activity. Intentional acts are produced by the self-organized microscopic neural activity of cortical and subcortical components in the brain. Awareness supervenes as a macroscopic ordering state, that defers action until the self-organizing microscopic process has reached closure in reflective prediction. Agency, which is removed from the causal hierarchy by the appeal to circularity, re-appears as a metaphor by which events in the world are anthropomorphized, making them appear subject to human control.

In this article, we present results from an interdisciplinary research project aimed at assessing consciousness in dreams. For this purpose, we compared lucid dreams with normal non-lucid dreams from REM sleep. Both lucid and non-lucid dreams are an important contrast condition for theories of waking consciousness, giving valuable insights into the structure of conscious experience and its neural correlates during sleep. However, the precise differences between lucid and non-lucid dreams remain poorly understood. The construction of the Lucidity and Consciousness (...) in Dreams scale was based on theoretical considerations and empirical observations. Exploratory factor analysis of the data from the first survey identified eight factors that were validated in a second survey using confirmatory factor analysis: INSIGHT, CONTROL, THOUGHT, REALISM, MEMORY, DISSOCIATION, NEGATIVE EMOTION, and POSITIVE EMOTION. While all factors are involved in dream consciousness, realism and negative emotion do not differentiate between lucid and non-lucid dreams, suggesting that lucid insight is separable from both bizarreness in dreams and a change in the subjectively experienced realism of the dream.

The concept of non-domination is an important contribution to the study of freedom but it does not comprehend the whole of freedom. Insofar as domination requires a conscious capacity for control on the part of the dominant party, it fails to capture important threats to individual freedom that permeate many contemporary liberal democracies today. Much of the racism, sexism and other cultural biases that currently constrain the life-chances of members of subordinate groups in the USA are largely unconscious (...) and unintentional, and they do not always involve control. Although they constitute real barriers to freedom, these forms of influence are not accurately characterized as domination, and they will require different mechanisms to overcome them. To achieve the more capacious freedoms that liberal democracy promises, we will need to go beyond non-domination and to come to terms with the non-sovereign, socially distributed character of human agency.

The world appears to conscious creatures in terms of experienced sensory qualities, but science doesn't find sensory experience in that world, only physical objects and properties. I argue that the failure to locate consciousness in the world is a function of our necessarily representational relation to reality as knowers: we won't discover the terms in which reality is represented by us in the world as it appears in those terms. Qualia -- arguably a type of representational content -- will (...) therefore not be found in the physical world as characterized in experience or science. Instead, consciousness constitutes a subjective, representational reality for cognitive systems such as ourselves, and the physical world is a represented objective reality. I suggest that naturalistic approaches to explaining consciousness should acknowledge the non-objectivity of experience, and be constrained by evidence that consciousness accompanies certain sorts of behaviour-controlling representational functions carried out by complex, physically instantiated mind-systems. I evaluate a variety of current hypotheses about consciousness, and suggest that a mature science of representation may help explain why, perhaps as matter of representational necessity, experience arises as a natural but not objectively discoverable phenomenon.

I argue on the basis of recent findings in neuroscience that consciousness is not a brain process, and then explore some alternative, non-reductive options concerning the metaphysical relationship between consciousness and the brain, such as weak and strong accounts of the emergence of consciousness and the constitution view of consciousness. I propose an Aristotelian account of the strong emergence of consciousness. This account motivates a wider ontology than reductive physicalism and makes reference to formal causation as a way explaining the (...) causal power of consciousness. What is meant by formal causation, in thiscontext, is that consciousness has the causal power to organize or control neuronal activity. This notion of causation is elaborated and supported by recent findings in the neurosciences. An advantage of this empirically informed approach is that proponents of the irreducibility of consciousness no longer need to rely upon conceptually based arguments alone, but can build a case against reductive physicalism that has a significant empirical foundation.

In “What is it like to be boring and myopic?” Kathleen Akins offers an interesting, empirically driven, argument for thinking that there is nothing that it is like to be a bat. She suggests that bats are “boring” in the sense that they are governed by behavioral scripts and simple, non-representational, control loops, and are best characterized as biological automatons. Her approach has been well received by philosophers sympathetic to empirically informed philosophy of mind. But, despite its influence, her (...) work has not met with any critical appraisal. -/- It is argued that a reconsideration of the empirical results shows that bats are not boring automatons, driven by short input-output loops, instincts, and reflexes. Grounds are provided for thinking that bats satisfy a range of philosophically and scientifically interesting elaborations of the general idea that consciousness is best understood in terms of representational functions. A more complete examination of bat sensory capabilities suggests there is something that it is like after all. -/- The discussion of bats is also used to develop an objection to strongly neurophilosophical approaches to animal consciousness.

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.

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.

Consciousness as used here, refers to the private, subjective experience of being aware of our perceptions, thoughts, feelings, actions, memories including the intimate experience of a unified self with the capacity to generate and control actions and psychological contents. This compelling, intuitive consciousness-centric account has, and continues to shape folk and scientific accounts of psychology and human behavior. Over the last 30 years, research from the cognitive neurosciences has challenged this intuitive social construct account when providing a neurocognitive architecture (...) for a human psychology. Growing evidence suggests that the executive functions typically attributed to the experience of consciousness are carried out competently, backstage and outside subjective awareness by a myriad of fast, efficient non-conscious brain systems. While it remains unclear how and where the experience of consciousness is generated in the brain, we suggested that the traditional intuitive explanation that consciousness is causally efficacious is wrong-headed when providing a cognitive neuroscientific account of human psychology. Notwithstanding the compelling 1st-person experience that convinces us that subjective awareness is the mental curator of our actions and thoughts, we argue that the best framework for building a scientific account is to be consistent with the biophysical causal dependency of prior neural processes. From a 3rd person perspective,, we propose that subjective awareness lacking causal influence, is than our experience of being aware, our awareness of our psychological content, knowing that we are aware, and the belief that that such experiences are evidence of an agentive capacity shared by others. While the human mind can be described as comprising both conscious and nonconscious aspects, both ultimately depend on neural process in the brain. In arguing for the counter-intuitive epiphenomenal perspective, we suggest that a scientific approach considers all mental aspects of mind including consciousness in terms of their underlying, preceding biological changes, in the realization that most brain processes are not accompanied by any discernible change in subjective awareness.

The notion of consciousness, though central to contemporary philosophy of mind, is not well understood. This fact vitiates many recent attempts to develop a theory of consciousness. I aim to achieve a deeper understanding of consciousness by considering what it is that distinguishes conscious mental phenomena from non-conscious mental phenomena. I argue that, contrary to widespread opinion, consciousness is not a matter of a mental state's possessing phenomenality. Nor is it simply a matter of an organism's developing a (...) mental representation, first order or higher order. Rather, I argue, conscious mental phenomena are distinguished from non-conscious mental phenomena by their positioning within a cognitive system. In particular, the conscious mental phenomena are all and only those that are both immediately available to a cognitive mechanism with the function of controlling behavior in novel circumstances and capable of engaging controlled attention. Although my account invokes something like Michael Tye's notion of a mental state's being "poised" to affect certain cognitive mechanisms, it differs from Tye's theory on which mechanisms a state must be poised to affect in order to be conscious. My account is further distanced from Tye's and Dretske's first order representational theories in that it does not restrict the contents of conscious experiences to non-conceptual contents. Rather, I maintain that the contents of conscious experiences are quite diverse, including both conceptual and non-conceptual contents. My arguments, both positive and negative, draw upon a variety of considerations, including the rich body of theory and data emerging from recent work in cognitive science, phenomenological considerations, and more general philosophical considerations such as overall coherence, simplicity, and argumentative support. If correct, my views not only undermine recent arguments for or against the explicability or reducibility of consciousness in physicalist terms, they show that those arguments are not about consciousness at all. Rather, on the framework that emerges in the dissertation, these arguments are about either the contents of mental phenomena or their phenomenal character---neither of which is consciousness.

Processes comparable in important respects to those underlying human conscious and non-conscious processing can be identified in a range of species and it is argued that these reflect evolutionary precursors of the human processes. A distinction is drawn between two types of processing: stimulus-based and higher-order. For ‘higher-order,’ in humans the operations of processing are themselves associated with conscious awareness. Conscious awareness sets the context for stimulus-based processing and its end-point is accessible to conscious awareness. (...) However, the mechanics of the translation between stimulus and response proceeds without conscious control. The paper argues that higher-order processing is an evolutionary addition to stimulus-based processing. The model’s value is shown for gaining insight into a range of phenomena and their link with consciousness. These include brain damage, learning, memory, development, vision, emotion, motor control, reasoning, the voluntary versus involuntary debate, and mental disorder. (shrink)

Attentional scanning was studied in anxious and non-anxious participants, using a modified change detection paradigm. Participants detected changes in pairs of emotional scenes separated by two task irrelevant slides, which contained an emotionally valenced scene and a visual mask. In agreement with attentional control theory, change detection latencies were slower overall for anxious participants. Change detection in anxious, but not non-anxious, participants was influenced by the emotional valence and exposure duration of distractor scenes. When negative distractor scenes were presented (...) at subliminal exposure durations, anxious participants detected changes more rapidly than when supraliminal negative scenes or subliminal positive scenes were presented. We propose that for anxious participants, subliminal presentation of emotionally negative distractor scenes stimulated attention into a dynamic state in the absence of attentional engagement. Presentation of the same scenes at longer exposure times was accompanied by conscious awareness, attentional engagement, and slower change detection. (shrink)

This volume brings together work in free will, ethics, metaethics, feminist theory, disability studies, experimental philosophy, and psychology. The theme for both the workshop and these papers was “Non-Ideal Agency and Responsibility,” and in these essays, our authors take a number of different and creative angles on this theme. Roughly half of the essays fall under the rubric of non-ideal agency. They discuss ways in which our agency is impacted by inherent psychological limitations, by the social contexts in which we (...) act, or by different ways in which our abilities can break down. The other half fall under the rubric of non-ideal responsibility. They discuss both the modes by which we assess imperfect exercises of our agency and the ways in which common forms of assessment are themselves imperfect. (shrink)

The dominant model for interpreting brain imaging experiments assumes that the brain is organized to support mental processes that control behavior. However functional neuroimaging experiments, particularly of cognitive tasks, have not shown a high level of reproducibility and localization. This lack of clear functional segregation has been blamed on limitations in imaging technology and non linearity and regional overlap in how the brain implements these processes. However the validity of the underlying cognitive models used to describe the brain have (...) rarely been questioned or directly tested against imaging results. We propose an alternative model of brain function which correlates observed human behavior directly with measured brain activity without assumptions about intervening cognitive processes, that we term the Non-Cognitive Behavioral Model (NBM). Our model derives from Behavioral Psychology but is extended to include brain activations in addition to behavior as an observable. A further extension is the role of neuroplasticity as opposed to innate cognitive processes in the development of the brains support of cognitive behavior. Applications of NBM to neuroimaging studies are described and contrasted with the standard methodology which we refer to as the Standard Cognitive Model (SCM). In one application, the NBM correctly predicted the global, total energy consumption as the brain parameter that best correlates with a person being in the state of consciousness, a correlation missed by studies using the SCM due to its assumption that global activity does not support cognitive processes. Neuroplasticity is shown to provide a natural explanation of findings that object recognition activating the fusiform facial area comes from expertise through raining as opposed to the SCM explanation of an innate cognitive process specialized for face recognition. The conclusions are generalized to explain the poor reproducibility of cognitive processes reported in functional neuroimaging and to suggest how such studies can be used to better explain how the brain supports behavior.

Speculations about the role of consciousness in physical systems are frequently observed in the literature concerned with the interpretation of quantum mechanics. While only three experimental investigations can be found on this topic in physics journals, more than 800 relevant experiments have been reported in the literature of parapsychology. A well-defined body of empirical evidence from this domain was reviewed using meta-analytic techniques to assess methodological quality and overall effect size. Results showed effects conforming to chance expectation in control (...) conditions and unequivocal non-chance effects in experimental conditions. This quantitative literature review agrees with the findings of two earlier reviews, suggesting the existence of some form of consciousness-related anomaly in random physical systems. (shrink)

The possibility of AI consciousness depends much on the correct answer to the mind–body problem: how our materialistic brain generates subjective consciousness? If a materialistic answer is valid, machine consciousness must be possible, at least in principle, though the actual instantiation of consciousness may still take a very long time. If a non-materialistic one (either mentalist or dualist) is valid, machine consciousness is much less likely, perhaps impossible, as some mental element may also be required. Some recent advances in neurology (...) (despite the separation of the two hemispheres, our brain as a whole is still able to produce only one conscious agent; the negation of the absence of a free will, previously thought to be established by the Libet experiments) and many results of parapsychology (on medium communications, memories of past lives, near-death experiences) suggestive of survival after our biological death, strongly support the non-materialistic position and hence the much lower likelihood of AI consciousness. Instead of being concern about AI turning conscious and machine ethics, and trying to instantiate AI consciousness soon, we should perhaps focus more on making AI less costly and more useful to society.

The extensive involvement of nonconscious processes in human behaviour has led some to suggest that consciousness is much less important for the control of action than we might think. In this article I push against this trend, developing an understanding of conscious control that is sensitive to our best models of overt action control. Further, I assess the cogency of various zombie challenges—challenges that seek to demote the importance of conscious control for human agency. (...) I argue that though nonconscious contributions to action control are evidently robust, these challenges are overblown. (shrink)

The abilities to attribute an action to its proper agent and to understand its meaning when it is produced by someone else are basic aspects of human social communication. Several psychiatric syndromes, such as schizophrenia, seem to lead to a dysfunction of the awareness of one’s own action as well as of recognition of actions performed by other. Such syndromes offer a framework for studying the determinants of agency, the ability to correctly attribute actions to their veridical source. Thirty normal (...) subjects and 30 schizophrenic patients with and without hallucinations and/or delusional experiences were required to execute simple finger and wrist movements, without direct visual control of their hand. The image of either their own hand or an alien hand executing the same or a different movement was presented on a TV-screen in real time. The task for the subjects was to discriminate whether the hand presented on the screen was their own or not. Hallucinating and deluded schizophrenic patients were more impaired in discriminating their own hand from the alien one than the non-hallucinating ones, and tended to misattribute the alien hand to themselves. Results are discussed according to a model of action control. A tentative description of the mechanisms leading to action consciousness is proposed. (shrink)

Anorexia Nervosa (AN) is widely considered to be a bodily disorder accompanied by unrealistic perceptions about one’s own body. Some researchers thus have wondered whether deficits in interoception, a conscious or non-conscious sense of one’s own body, could be a primary cause of AN. In this paper, we make the case that rather than interoception being a primary cause, deficits in interoception may occur as by-products of emotions that arise upstream in the pathogenesis of AN and interact with (...) feelings of a loss of self-control. We consider interoception, emotion, and self-control as a dynamical triad involved in the explanation of AN, with emotions as the central aspect of their interactions. We begin with a critical analysis of recent empirical literature on AN and differentiate three types of interoceptive processes. We then consider the role of self-control in AN. We go on to evaluate recent empirical and philosophical work on the role of emotions in AN and assess their importance in both interoception and self-control dynamics. We develop a testable integrative model that we believe best captures how self-control, emotional and interoceptive processes causally interact in the pathogenesis of AN. In this model, AN behaviors are not caused by interoceptive abnormalities, but rather interact with changes in emotional regulation and feelings of loss of self-control, subsequently leading to interoceptive deficits downstream. To capture a later stage in the pathogenesis of AN, we show how AN behaviors are maintained as a result of feedback among components in the model. We briefly explain future plans to further complement the model using a semi-structured interview to probe patient perspectives in AN. To develop a more valid understanding of AN, this model will have to be integrated into pluralistic approaches that include patient perspectives. (shrink)

In 1968, the Harvard criteria equated irreversible coma and apnea with human death and later, the Uniform Determination of Death Act was enacted permitting organ procurement from heart-beating donors. Since then, clinical studies have defined a spectrum of states of impaired consciousness in human beings: coma, akinetic mutism, minimally conscious state, vegetative state and brain death. In this article, we argue against the validity of the Harvard criteria for equating brain death with human death. Brain death does not disrupt (...) somatic integrative unity and coordinated biological functioning of a living organism. Neurological criteria of human death fail to determine the precise moment of an organism’s death when death is established by circulatory criterion in other states of impaired consciousness for organ procurement with non-heart-beating donation protocols. The criterion of circulatory arrest 75 s to 5 min is too short for irreversible cessation of whole brain functions and respiration controlled by the brain stem. Brain -based criteria for determining death with a beating heart exclude relevant anthropologic, psychosocial, cultural, and religious aspects of death and dying in society. Clinical guidelines for determining brain death are not consistently validated by the presence of irreversible brain stem ischemic injury or necrosis on autopsy; therefore, they do not completely exclude reversible loss of integrated neurological functions in donors. The questionable reliability and varying compliance with these guidelines among institutions amplify the risk of determining reversible states of impaired consciousness as irreversible brain death. The scientific uncertainty of defining and determining states of impaired consciousness including brain death have been neither disclosed to the general public nor broadly debated by the medical community or by legal and religious scholars. Heart-beating or non-heart-beating organ procurement from patients with impaired consciousness is de facto a concealed practice of physician-assisted death, and therefore, violates both criminal law and the central tenet of medicine not to do harm to patients. Society must decide if physician-assisted death is permissible and desirable to resolve the conflict about procuring organs from patients with impaired consciousness within the context of the perceived need to enhance the supply of transplantable organs.

I seek an explanation for the etiology and the function of mind wandering episodes. My proposal – which I call the cognitive control proposal – is that mind wandering is a form of non-conscious guidance due to cognitive control. When the agent’s current goal is deemed insufficiently rewarding, the cognitive control system initiates a search for a new, more rewarding goal. This search is the process of unintentional mind wandering. After developing the proposal, and relating it (...) to literature on mind wandering and on cognitive control, I discuss explanations the proposal affords, testable predictions the proposal makes, and philosophical implications the proposal has.

A naturalistic account of self-consciousness is developed within a general framework in which thought contents are structured by concepts but conceptual content need not be exhausted at the level of reference. To motivate the first feature of this framework, possible-worlds- and property-based theories of thought content, which eschew structure, are criticized for overestimating and/or underestimating the attitude stock of ordinary agents. To motivate the second feature, it is argued that neo-Russellian and neo-Fregean accounts, which incorporate structure but differ on the (...) semantic classification of psychological modes of presentation, are more or less on a par with respect to standard parameters of evaluation . Though non-notational differences between these accounts remain, these differences add up to less than is commonly supposed. ;Neo-Russellians and neo-Fregeans agree on the explanatory relevance of conceptual modes of presentation, understood as reference-sustaining functional mechanisms; what they disagree about is whether those modes contribute to the content of a concept. Once the semantic dispute is set aside, questions about the nature of these mechanisms come to the fore. In the case of the self concept, what appears to distinguish this concept from coreferring items in an agent's conceptual repertoire is its privileged relation to inputs from internal monitoring systems, on one side, and outputs in control systems, on the other. Self-consciousness emerges as an atomistic conceptual capacity, sustained by both interoceptual mechanisms and agentive ones. (shrink)

This is the second of four online Companions to Velmans, M. (ed.) (2018) Consciousness (Critical Concepts in Psychology), a 4-volume collection of Major Works on Consciousness commissioned by Routledge, London. -/- The Companion to Volume 2 Part 1 focuses on the detailed relationship of phenomenal consciousness to mental processing described either functionally (as human information processing) or in terms of neural activity, in the ways typically explored by cognitive psychology and cognitive neuroscience. Beginning with reviews of functional differences between unconscious, (...) preconscious and conscious processing and the different senses in which mental processing can be said to be “conscious”, the readings turn to seminal work on blindsight and related phenomena, experimental evidence of perception without awareness, ways to combine “subjective” and “objective” measures of awareness, evidence for distinct neural pathways governing visual awareness and visual control of motor acts, and the complex ways in which consciousness of action relates to both voluntary and involuntary acts. The readings then focus on the intimate links between attention and consciousness, starting with the writings of William James and surveying the extensive work on this subject over the last 60 years that explores the relationships between and attended and non-attended processing, preconscious and conscious processing, and attention, primary (working, short-term) memory and consciousness. The readings go on to survey the evidence that attention contributes to the “neural binding” required for an integrated conscious experience and evidence that attention (in humans) is dissociable from consciousness, necessary for consciousness, but not sufficient for consciousness. The readings then turn to research on “inattentional blindness”, and conclude with a review of Baars’ global workspace theory, which integrates many theories and findings in this area into a coherent, global model. The Companion then summarises seminal readings on learning, memory and consciousness; the extensive research on mental imagery, long thought to epitomize private, subjective conscious experience—and consequently ruled out of science by reductive, materialist philosophies of mind; the complex relations of consciousness to sleep and dreaming; the development of consciousness in human infants; and the debates surrounding, and extensive evidence for consciousness in non-human animals, with attendant consequences for their humane treatment. -/- As with the other Companions to these Volumes there are many links to background resources (marked in pink) and to the selected readings themselves (marked in blue).

Psychedelics have been recognized as model interventions for studying altered states of consciousness. However, few empirical studies of the shamanic state of consciousness, which is anecdotally similar to the psychedelic state, exist. We investigated the neural correlates of shamanic trance using high-density electroencephalography (EEG) in 24 shamanic practitioners and 24 healthy controls during rest, shamanic drumming, and classical music listening, followed by an assessment of altered states of consciousness. EEG data were used to assess changes in absolute power, connectivity, signal (...) diversity, and criticality, which were correlated with assessment measures. We also compared assessment scores to those of individuals in a previous study under the influence of psychedelics. Shamanic practitioners were significantly different from controls in several domains of altered states of consciousness, with scores comparable to or exceeding that of healthy volunteers under the influence of psychedelics. Practitioners also displayed increased gamma power during drumming that positively correlated with elementary visual alterations. Furthermore, shamanic practitioners had decreased low alpha and increased low beta connectivity during drumming and classical music and decreased neural signal diversity in the gamma band during drumming that inversely correlated with insightfulness. Finally, criticality in practitioners was increased during drumming in the low and high beta and gamma bands, with increases in the low beta band correlating with complex imagery and elementary visual alterations. These findings suggest that psychedelic drug-induced and non-pharmacologic alterations in consciousness have overlapping phenomenal traits but are distinct states of consciousness, as reflected by the unique brain-related changes during shamanic trance compared to previous literature investigating the psychedelic state.

In both biology and psychology, the notion of an individual is indispensable yet puzzling. It has played a variety of roles in diverse contexts, ranging from philosophical problems of personal identity to scientific questions about the immunological mechanisms for telling ‘self’ from ‘non-self.’ There are notorious cases in which the question of individuality is difficult to settle — ant hill, slime mold, or beehive, for instance. Yet the notion of an individual organism, both dependent on and independent of other individuals (...) in specific ways, is crucial to our conception of life itself. It is also crucial to our notion of mentality, and hence to other concepts — moral and social — which must be explicated in terms of individual mentality. (Think, for example, of the importance of the quality and nature of individual consciousness to debates about abortion and euthanasia.). (shrink)

ObjectivesA sample of women with persistent distress following breast cancer previously exhibited attentional bias away from supraliminally presented cancer-or threat-related information, responses consistent with avoidance coping, and showed negative interpretation bias. Here, we attempt to characterize the nature of supraliminal AB and interpretation bias in that sample of women by comparing against healthy controls.MethodsExtending our previous work, we compared AB patterns for supraliminally presented negatively valenced words and cancer-related information assessed by modified dot-probe tasks and negative interpretation bias assessed by (...) an ambiguous cue task between 140 BC women previously identified as featuring low-stable or persistent high anxiety and 150 age-matched non-BC healthy controls having HADS-defined low or high anxiety.ResultsAttentional avoidance of non-cancer-related negatively valenced words was seen among the anxious BC group, while heightened attention toward such words was seen in anxious healthy controls, F = 3.97, p = 0.009. However, all anxious women in both BC and healthy groups directed attention away from CRI under supraliminal conditions. Interpretation bias scores were significantly higher in BC women with high anxiety vs. healthy controls with high anxiety, F = 13.26, p < 0.001.ConclusionWomen with high anxiety generalized conscious attentional avoidance responses to negatively valenced stimuli, indicating a likely hypersensitivity to potential threat in ambiguous cues and exaggerated threat perception. This may cause maladaptive emotional regulation. Attention focus training, reducing threat salience or modifying threat appraisal, may help women alleviate anxiety levels after BC. (shrink)
