“Perception is controlled hallucination,” according to proponents of predictive processing accounts of vision. I say they are right that something like this is a consequence of their view but wrong in how they have pursued the idea. The focus of my counterproposal is the causal theory of perception, which I develop in terms of a productive concept of causation. Cases of what otherwise seem like successful perception are instead mere veridical hallucination if predictive processing accounts are correct, (...) I argue, because of the role played within such accounts by absences, which cannot enter into productive causal relations. -/- I offer two arguments in support of the productive theory of perception. The first is loosely Kantian, focusing on the role that receptivity and spontaneity play in perception. The second focuses on what perception and hallucination have in common. I conclude with a series of objections and replies. (shrink)

We present Activity Analysis as a new method for the quantification of subjective reports of altered states of consciousness with regard to the indicated level of simulated motor activity. Empirical linguistic activity analysis was conducted with dream reports conceived immediately after EEG-controlled periods of hypnagogic hallucinations and REM-sleep in the sleep laboratory. Reports of REM-dreams exhibited a significantly higher level of simulated physical dreamer activity, while hypnagogic hallucinations appear to be experienced mostly from the point of passive observer. This (...) study lays the groundwork for clinical research on the level of simulated activity in pathologically altered states of subjective experience, for example in the REM-dreams of clinically depressed patients, or in intrusions and dreams of patients diagnosed with PTSD.

Do self‐monitoring accounts, a dominant account of the positive symptoms of schizophrenia, explain auditory verbal hallucination? In this essay, I argue that the account fails to answer crucial questions any explanation of auditory verbal hallucination must address. Where the account provides a plausible answer, I make the case for an alternative explanation: auditory verbal hallucination is not the result of a failed control mechanism, namely failed self‐monitoring, but, rather, of the persistent automaticity of auditory experience of a (...) voice. My argument emphasizes the importance of careful examination of phenomenology as providing substantive constraints on causal models of the positive symptoms in schizophrenia. (shrink)

Behrendt & Young (B&Y) suggest that hallucinations occur as a result of decoupling of neuronal populations from sensory control. I propose that such a decoupling is in fact a constant feature of brain activity, even under nonpathological conditions. This position is justified by evidence from recent neurophysiological recording studies. I suggest that hallucinations arise because of a breakdown in segregation of internally and externally generated activity in a neuronal population.

About 75% of subjects diagnosed with schizophrenia experience auditory-verbal hallucination and report "hearing voices" that are not actually present. One notable feature of AVH is that it seems involuntary and not directly in the subject's control. With regard to content, these represented voices make utterances, typically commands and evaluations, and either are directed to the patient or speak about her in the third person. Voices may echo the subject's thoughts or comment on the subject's behavior and, in some cases, (...) the voices seem to carry on conversations or even argue. Subjects often experience the voices as having pitch, timbre, and intensity, and as having a... (shrink)

Phillips & Silverstein argue that schizophrenia is a result of a deficit of the contextual coordination of neuronal responses. The authors propose that NMDA-receptors control these modulatory effects. However, hallucinations, which are among the principle symptoms of schizophrenia, imply a flaw in the interactions between neurons that is more fundamental than just a general weakness of contextual modulation.

A seminal work on the unconscious and its mechanisms. Examines the interaction between voluntary (conscious) and involuntary (unconscious) human control mechanisms in terms of dissociation of divided consciousness. Delineates a neodissociation interpretation that recognizes historical roots without requiring commitment. Presents a wide range of data on possession states, fugues, multiple personalities, amnesia, dreams, hallucinations, automatic writing, and aggressions.

Recent neural models clarify many properties of mental imagery as part of the process whereby bottom-up visual information is influenced by top-down expectations, and how these expectations control visual attention. Volitional signals can transform modulatory top-down signals into supra-threshold imagery. Visual hallucinations can occur when the normal control of these volitional signals is lost.

Background. Positive schizophrenic symptoms, especially passivity phenomena, including auditory hallucinations, may be caused by an abnormal sense of agency, which people with schizotypal personality traits also tend to exhibit. A sense of agency asserts that it is oneself who is causing or generating an action. It is possible that this abnormal sense of self-agency is attributable to the abnormal prediction of one’s own movements in motor control. Method. We conducted an experiment using the “disappeared cursor” paradigm in which non-clinical, healthy (...) participants were required to click on a target using an invisible mouse cursor. Prediction error was defined as the distance between the target and the click point. Results. The results showed that schizotypal personality traits, but not depressive or anxious traits, were correlated with deficits in predicting movements of the subjects’ left hand. In particular, auditory hallucination proneness had the strongest relationship with movement prediction error. In this report, we also discuss the error tendency. Conclusions. This finding is in accordance with the idea that passivity phenomena or proneness may be caused by the abnormal prediction of one’s own actions or movements. (shrink)

RESUMEN Desde 1980, C. D. Frith investiga la esquizofrenia, y explica sus síntomas centrales como las alucinaciones, con miras a aclarar cuál es el déficit originario de este trastorno mental. Frith propone una hipótesis centrada en el concepto de conciencia, que ha elaborado como parte del desarrollo científico contemporáneo. En primer lugar, como parte de la aplicación de modelos neurocognitivos de control motor, según los cuales el déficit se atribuye al concepto de copia eferente y su función. En segundo lugar, (...) la actualiza y complementa con evidencia de imagen cerebral de la atenuación de la actividad cortical parietal, como efecto derivado de la copia eferente. En tercer lugar, adiciona el concepto de sentido de agencia, y el componente de cognición social, intentando integrar la experiencia del paciente y la relevancia del ámbito intersubjetivo a su propuesta. Este artículo hace una revisión crítica de la hipótesis de Frith y se divide en cuatro partes: primero, se presenta una síntesis de la evolución de la hipótesis; segundo, se sintetiza su argumentación; tercero, se presentan los principales puntos críticos y, por último, se derivan unas conclusiones generales. ABSTRACT Since 1980, C. D. Frith has been working on schizophrenia, and explaining central symptoms such as hallucinations, in an attempt to clarify the basic deficits of this mental disorder. Frith has put forth a hypothesis based on the concept of consciousness, and has been adjusting it alongside contemporary scientific developments. In first place, it begins with the use of neurocognitive models of motor control, according to which the deficit is attributable to the concept of efferent copy and its function. In second place, he updated the model by including neuroimaging evidence of attenuation in parietal activity, as a consequence of the efferent copy. In third place, he added the concept of sense of agency, and the social cognition component, trying to integrate to his proposal the patient's experience and the relevance of the inter-subjective aspect. The current paper, which critically reviews Frith's hypothesis, it's divided in four parts: First, the hypothesis' evolution is synthesized; second, the main arguments are summarized; third, the main critical points are presented; and, finally, some general conclusions are drawn.

In response to criticisms of phenomenology as being a solipsistic approach to psychological research and theory, this paper examines the interplay of both the creative/active and receptive/passive constituents of subjective experience identified in Husserl's exposition of intentional analysis. By delineating the ways in which intentional constitution requires passive as well as active processes, we come to see in the first part of this paper how experience and personal identity are as much formed and informed by the social and historical world (...) as they are created by individual subjects. Once we have established the non-solipsistic nature of phenomenology, we then apply it in the second part of this paper to open a window onto the disorder of self long considered to be integral to schizophrenia. Through an exploration of the constitution of sense of self in the experiences of two people with schizophrenia, we see how cognitive disruptions, auditory hallucinations, and delusional ideation may be related to fundamental peculiarities in a person's experiences of intentionality and his/her resulting sense of agency and identity. In conclusion, we suggest that while phenomenology may not be able to provide a complete account of psychosis, it may be used to shed valuable, descriptive light on subjective aspects that provide a conceptual base for the consideration of other factors.

This paper aims to provide a theoretical framework for explaining the subjective character of pain experience in terms of what we will call ‘embodied predictive processing’. The predictive processing (PP) theory is a family of views that take perception, action, emotion and cognition to all work together in the service of prediction error minimisation. In this paper we propose an embodied perspective on the PP theory we call the ‘embodied predictive processing (EPP) theory. The EPP theory proposes to explain pain (...) in terms of processes distributed across the whole body. The prediction error minimising system that generates pain experience comprises the immune system, the endocrine system, and the autonomic system in continuous causal interaction with pathways spread across the whole neural axis. We will argue that these systems function in a coordinated and coherent manner as a single complex adaptive system to maintain homeostasis. This system, which we refer to as the neural-endocrine-immune (NEI) system, maintains homeostasis through the process of prediction error minimisation. We go on to propose a view of the NEI ensemble as a multiscale nesting of Markov blankets that integrates the smallest scale of the cell to the largest scale of the embodied person in pain. We set out to show how the EPP theory can make sense of how pain experience could be neurobiologically constituted. We take it to be a constraint on the adequacy of a scientific explanation of subjectivity of pain experience that it makes it intelligible how pain can simultaneously be a local sensing of the body, and, at the same time, a more global, all-encompassing attitude towards the environment. Our aim in what follows is to show how the EPP theory can meet this constraint. (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)

We present one of the first quantitative studies on auditory verbal experiences (“hearing voices”) and auditory verbal agency (inner speech, and specifically “talking to (imaginary) voices or characters”) in healthy participants across states of consciousness. Tools of quantitative linguistic analysis were used to measure participants’ implicit knowledge of auditory verbal experiences (VE) and auditory verbal agencies (VA), displayed in mentation reports from four different states. Analysis was conducted on a total of 569 mentation reports from rapid eye movement (REM) sleep, (...) non‐REM sleep, sleep onset, and waking. Physiology was controlled with the nightcap sleep–wake mentation monitoring system. Sleep‐onset hallucinations, traditionally at the focus of scientific attention on auditory verbal hallucinations, showed the lowest degree of VE and VA, whereas REM sleep showed the highest degrees. Degrees of different linguistic‐pragmatic aspects of VE and VA likewise depend on the physiological states. The quantity and pragmatics of VE and VA are a function of the physiologically distinct state of consciousness in which they are conceived. (shrink)

Disorders of agency could be described as cases where people encounter difficulties in assessing their own degree of responsibility or involvement with respect to a relevant action or event. These disturbances in one’s sense of agency appear to be meaningfully connected with some mental disorders and with some symptoms in particular—i.e. auditory verbal hallucinations, thought insertion, pathological guilt. A deeper understanding of these experiences may thus contribute to better identification and possibly treatment of people affected by such disorders. In this (...) paper I explore disorders of agency to flesh out their phenomenology in more detail as well as to introduce some theoretical distinctions between them. Specifically, I argue that we may better understand disorders of agency by characterizing them as dimensional. In §1 I explore the cases of Auditory Verbal Hallucinations (AVH) and pathological guilt and I show that they lie at opposite ends of the agency spectrum (i.e. hypoagency versus hyperagency). In §2 I focus on two intermediate cases of hypo- and hyper- agency. These are situations that, despite being very similar to pathological ones, may be successfully distinguished from them in virtue of quantitative factors (e.g. duration, frequency, intensity). I first explore the phenomenon of mind wandering as an example of hypoagency, and I then discuss the phenomenon of false confessions as an example of hyperagency. While cases of hypoagency exemplify situations where people experience their own thoughts, bodies, or actions as something beyond their control, experiences of hyperagency provide an illusory sense of control over actions or events.

The experience of conscious will is the feeling that we are doing things. This feeling occurs for many things we do, conveying to us again and again the sense that we consciously cause our actions. But the feeling may not be a true reading of what is happening in our minds, brains, and bodies as our actions are produced. The feeling of conscious will can be fooled. This happens in clinical disorders such as alien hand syndrome, dissociative identity disorder, and (...) schizophrenic auditory hallucinations. And in people without disorders, phenomena such as hypnosis, automatic writing, Ouija board spelling, water dowsing, facilitated communication, speaking in tongues, spirit possession, and trance channeling also illustrate anomalies of will – cases when actions occur without will or will occurs without action. This book brings these cases together with research evidence from laboratories in psychology to explore a theory of apparent mental causation. According to this theory, when a thought appears in consciousness just prior to an action, is consistent with the action, and appears exclusive of salient alternative causes of the action, we experience conscious will and ascribe authorship to ourselves for the action. Experiences of conscious will thus arise from processes whereby the mind interprets itself – not from processes whereby mind creates action. Conscious will, in this view, is an indication that we think we have caused an action, not a revelation of the causal sequence by which the action was produced. Key Words: apparent mental causation; automatism; conscious will; determinism; free will; perceived control. (shrink)

Sense of agency is a compelling but fragile experience that is augmented or attenuated by internal signals and by external cues. A disruption in SoA may characterise individual symptoms of mental illness such as delusions of control. Indeed, it has been argued that generic SoA disturbances may lie at the heart of delusions and hallucinations that characterise schizophrenia. A clearer understanding of how sensorimotor, perceptual and environmental cues complement, or compete with, each other in engendering SoA may prove valuable in (...) deepening our understanding the agency disruptions that characterise certain focal neurological disorders and mental illnesses. Here we examine the integration of SoA cues in health and illness, describing a simple framework of this integration based on Bayesian principles. We extend this to consider how alterations in cue integration may lead to aberrant experiences of agency. (shrink)

There has recently been emphasis put on providing two-factor accounts of monothematic delusions. Such accounts would explain (1) whether a delusional hypothesis (e.g. someone else is inserting thoughts into my mind) can be understood as a prima facie reasonable response to an experience and (2) why such a delusional hypothesis is believed and maintained given its implausibility and evidence against it. I argue that if we are to avoid obfuscating the cognitive mechanisms involved in monothematic delusion formation we should split (...) the first factor (1 above) into two factors: how abnormal experience can give rise to a delusional ‘proto-hypothesis’ and how a ‘proto-hypothesis’ in consort with normal experiences and background information, can be developed into a delusional hypothesis. In particular I will argue that a schizophrenic is faced with the unusual requirement of having to identify an introspectively accessible thought as one's own, and that this requirement of identification is the central experiential abnormality of thought insertion, auditory verbal hallucination, and alien control (i.e. passivity symptoms). Additionally, I will consider non-experiential factors which are required for the formation of a delusional hypothesis. (shrink)

The etiology of visual hallucinations is largely undetermined in schizophrenia. Collerton et al.'s PAD model partly concurs with what we know about neurocognition in schizophrenia, but we need to specify the types of perceptual and attentional abnormalities that are implicated in recurrent complex visual hallucinations (RCVH). Available data suggest that abnormal attentional control and top-down processing play a larger role than the ventral stream deficits.

Much of the characteristic symptomatology of schizophrenia can be understood as resulting from a pervasive sense of disembodiment. The body is experienced as an external machine that needs to be controlled with explicit intentional commands, which in turn leads to severe difficulties in interacting with the world in a fluid and intuitive manner. In consequence, there is a characteristic dissociality: Others become problems to be solved by intellectual effort and no longer present opportunities for spontaneous interpersonal alignment. This dissociality (...) goes hand in hand with a progressive loss of the socially extended mind, which normally affords opportunities for co-regulation of cognitive and affective processes. However, at times people with schizophrenia report that they are confronted by the opposite of this dissociality, namely an unusual fluidity of the self-other boundary as expressed in experiences of ambiguous body boundaries, intrusions, and even merging with others. Here the person has not lost access to the socially extended mind but has instead become lost in it, possibly due to a weakened sense of self. We argue that this neglected aspect of schizophrenic social dysfunction can be usefully approached via the concept of genuine intersubjectivity: We normally participate in a shared experience with another person by implicitly co-regulating how our interaction unfolds. This co-regulation integrates our respective experience’s dynamical bases into one interpersonal process and gives the interaction an ambiguous second-person character. The upshot is that reports of abnormal self-other fluidity are not indicative of hallucinations without any basis in reality, but of a heightened sensitivity and vulnerability to processes of interpersonal alignment and mutual incorporation that form the normal basis of social life. We conclude by discussing implications of this view for both the science of consciousness as well as approaches to intervention and therapy. (shrink)

The primary narrative problem of the analyst is, then, not how to tell a normative chronological life history; rather, it is how to tell the several histories of each analysis. From this vantage point, the event with which to start the model analytic narration is not the first occasion of thought—Freud's wish-fulfilling hallucination of the absent breast; instead, one should start from a narrative account of the psychoanalyst's retelling of something told by an analysand and the analysand's response to (...) that narrative transformation. In the narration of this moment of dialogue lies the structure of the analytic past, present, and future. It is from this beginning that the accounts of early infantile development are constructed. Those traditional developmental accounts, over which analysts labored so hard, may now be seen in a new light: less as positivistic sets of factual findings about mental development and more as hermeneutically filled-in narrative structures. The narrative structures that have been adopted control the telling of the events of the analysis, including the many tellings and retellings of the analysand's life history. The time is always present. The event is always an outgoing dialogue.

To what extent do I have a sense of agency over my thoughts while I dream? The sense of agency in dreams can alter in a variety of interesting ways distinct from normal, waking experience. In fact, dreams show many similarities to the experiences of individuals with schizophrenia. In this paper I analyze these alterations with a focus on distinguishing between reduced sense of agency and other cognitive features such as metacognition, confabulation and attention. I argue that some dream reports (...) demonstrate two interesting commonalities with schizophrenia: thought insertion (TI) and auditory hallucination (AH). This line of research has the potential to further our understanding of TI and AH in schizophrenia through the analysis of similar experience in a different conscious state. Through the analysis of dream reports, I found that although TI and AH both occur in dreams, TI is very rare. This is an interesting result since TI is common in patients with schizophrenia. I propose two speculative lines of explanation for the rarity of TI in dreams: first, the cognitive differences between the symptoms of schizophrenia and dreams, and second, the problem of dream reporting conditions. Dream reporting conditions are particularly important, as without controls, reports can be vague. Analysis of dream reports reveals that it is often unclear whether 'hearing voices' indicates sound phenomenology or thought phenomenology. I propose that dream reports could be disambiguated given the right experimental conditions and I suggest how this could be achieved in future experimental research. (shrink)

Introduction. The sense of agency over thoughts is the experience of oneself qua agent of mental action. Those suffering certain psychotic symptoms are thought to have a deficient sense of agency. Here I seek to explain this sense of agency in terms of metacognition. Method. I start with the proposal that the sense of agency is elicited by metacognitive monitoring representations that are used in the intentional inhibition of thoughts. I apply this model to verbal hallucinations and the like and (...) examine the plausibility of this model explaining deficits associated with these symptoms. Results. By tying the sense of agency to metacognitive inhibition I propose that the loss of a sense of agency in certain psychotic symptoms is accompanied by a particular deficit in the patient’s ability to control their own thinking. This is consistent with the experiences of those at high risk of developing hallucinations, who report more intrusive thoughts than controls. The model I present is able to explain why those at risk of developing verbal hallucinations and those suffering from verbal hallucinations have deficits in the intentional inhibition of thought. I defend this account from a possible objection by distinguishing the form of the intentional inhibition deficit displayed by those suffering verbal hallucination from that displayed by those suffering from orbital-frontal cortex lesions and posttraumatic stress disorder. Conclusion. A plausible hypothesis is that the sense of agency over thoughts is elicited by the metacognitive monitoring representation used to intentionally inhibit. (shrink)

The World In Your Head: A Gestalt View of the Mechanism of Conscious Experience represents a bold assault on one of the greatest unsolved mysteries in science: the nature of consciousness and the human mind. Rather than examining the brain and nervous system to see what they tell us about the mind, this book begins with an examination of conscious experience to see what it can tell us about the brain. Through this analysis, the first and most obvious observation is (...) that consciousness appears as a volumetric spatial void, containing colored objects and surfaces. This reveals that the representation in the brain takes the form of an explicit volumetric spatial model of external reality. Therefore, the world we see around us is not the real world itself, but merely a miniature virtual-reality replica of that world in an internal representation. In fact, the phenomena of dreams and hallucinations clearly demonstrate the capacity of the brain to construct complete virtual worlds even in the absence of sensory input. Perception is somewhat like a guided hallucination, based on sensory stimulation. This insight allows us to examine the world of visual experience not as scientists exploring the external world, but as perceptual scientists examining a rich and complex internal representation. This unique approach to investigating mental function has implications in a wide variety of related fields, including the nature of language and abstract thought, and motor control and behavior. It also has implications to the world of music, art, and dance, showing how the patterns of regularity and periodicity in space and time--apparent in those aesthetic domains--reflect the periodic basis set of the underlying harmonic resonance representation in the brain.

Many mental phenomena involve thinking about people who do not exist. Imagined characters appear in planning, dreams, fantasizing, imaginary companions, bereavement hallucinations, auditory verbal hallucinations, and as characters created in fictional narratives by authors. Sometimes these imagined persons are felt to be completely under our control, as when one fantasizes about having a great time at a party. Other times, characters feel as though they are outside of our conscious control. Dream characters, for example, are experienced by dreamers as autonomous (...) entities, and often do things that frighten and surprise dreamers. Some imagined persons, such as characters in fiction, start off under conscious control of the author, but over time, can appear to gain an illusion of independent agency. I propose an explanation for different autonomy attributions: characters are by default non-autonomous, unless their personalities are well-practiced. Characters become autonomous because modeling their thinking has become automatized, like many other well-practiced activities. (shrink)

"[Reading Ebersole] requires and often succeeds in producing a radical reorientation of one´s thinking . . . " from a book review Things We Know is a collection of fifteen essays that focus on perennial philosophical problems about knowledge. The essays let you participate in Frank Ebersole´s unique struggles to come to terms with such questions as: Can we know the world? . . . the past? . . . the future? . . . of God´s existence? . . . (...) whether our actions are free? . . . the foundations of logic and language? This is not just another philosophy book about problems of knowledge. In Things We Know, Ebersole, by carefully using examples, exposes the problems to be the products of philosophical pictures. The examples also make the pictures less compelling. Thus, by reading this philosophy book readers can join the author in working to free themselves from some perplexing philosophical concerns. How the Second Edition differs from the First Edition This edition differs from the First Edition (University of Oregon Books, 1967) in three ways. An essay is added. "Everyman´s Ontological Argument" has been inserted as Essay 14, following two other essays about the ontological argument. "Everyman´s Ontological Argument" was published in the Fall 1978 issue of Philosophical Investigations. (The original Chapter 14, "Where the Action Is," is now Chapter 15.) An essay is replaced. The original Essay 3, "How Philosophers See Stars," has been replaced by a modified version that was printed in Philosophy Today (no. 2, 1969). The replacement includes some further improvements. The text is improved. Throughout the book, the author has made corrections, stylistic improvements, and changed the wording as needed to make clearer his line of thought. Summary Each of the fifteen essays takes up a philosophical problem. In most of the essays, Ebersole first clarifies the problem and reviews common attempts to resolve the problem. Then he focuses on the central ideas and terms used to state the problem and creates examples of people using the terms under consideration. The examples are unique because of their focus on the context and point of what we say. If his investigations fail to find a use of the terms that supports the philosophical problem, he is led to conclude that the problem does not really derive from a philosophical insight but rather arises from a philosophical picture or model. Preface The essays in Things We Know address some of the perennial philosophical problems of knowledge. The essays are unified by being similar in method and philosophic aim. Ebersole exposes a picture behind each problem. In the essays he works through some of the ways that pictures control our thinking and tries to make the pictures less compelling. Chapters 1 6: Perception and Language Chapter 1: "Seeing Red in Red Things" Philosophical problem: Must words for simple visual properties (e.g., "red") refer to things because the things share some property (e.g., redness)? Can we see this property? Topics investigated: Family resemblances, properties of colors, when we regard things as the same, when we regard colors as the same, when we regard things as having common properties, language-world philosophical pictures. Philosophers discussed: A. J. Ayer, J. Herder, J. S. Mill. Chapter 2: "Seeing Things" Philosophical problem: Do hallucinations and afterimage. (shrink)

Disparate theoretical viewpoints construe hypnotic suggestibility either as a stable trait, largely determined by underlying cognitive aptitude, or as a flexible skill amenable to attitudinal factors including beliefs and expectations. Circumscribed findings support both views. The present study attempted to consolidate these orthogonal perspectives through the lens of expectancy modification. We surreptitiously controlled light and sound stimuli to convince participants that they were responding strongly to hypnotic suggestions for visual and auditory hallucinations. Extending our previous findings, we indexed hypnotic (...) suggestibility by de-automatizing an involuntary audiovisual phenomenon—the McGurk effect. Here we show that, regardless of expectancy modification, the experimental procedure led to heightened expectations concerning future hypnotic response. We found little effect of expectation, however, on actual response to suggestion. Our findings intimate that, at least in the present experimental context, expectation hardly correlates with—and is unlikely to be a primary determinant of—high hypnotic suggestibility. (shrink)

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.

Motor imagery provides a direct insight into action representations. The aim of the present study was to investigate the level of impairment of action monitoring in schizophrenia by evaluating the performance of schizophrenic patients on mental rotation tasks. We raised the following questions: Are schizophrenic patients impaired in motor imagery both at the explicit and at the implicit level? Are body parts more difficult for them to mentally rotate than objects? Is there any link between the performance and the hallucinating (...) symptom profile? The schizophrenic patients displayed the same pattern of performance as the control subjects . More particularly, schizophrenic patients’ reaction time varied as a function of the angular disparity of the stimuli. On the other hand, they were significantly slower and less accurate. Interestingly, patients suffering from hallucinations made significantly more errors than non-hallucinatory patients. We discussed these latter results in terms of deficit of the forward model. We emphasized the necessity to distinguish different levels of action, more or less impaired in schizophrenia. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Schizophrenic Delusions, Embodiment, and the BackgroundGiovanni Stanghellini (bio)Keywordsschizophrenia, delusion, embodiment, common sense, phenomenologyIn their article Delusions, Certainty, and the Background, Rhodes and Gipps (2008) argue for a Background theory of delusions. Their central argument may be summed up as follows:• The formation and maintenance of delusions becomes intelligible once they are seen to reflect a basic disturbance. When studying delusions, the focus should be on providing an adequate framework (...) for understanding, rather than providing empirical hypotheses to be tested.• The basic disturbance in delusions, and insanity in general, is not a deficiency in reasoning or a defect in the content of experience, but rather something more fundamental.• Delusions––this is their central claim––are caused by a failure of the Bedrock of beliefs (Wittgenstein) or the Background (Searle) to adequately inform or constrain the process of belief formation.• Our Bedrock certainties are defined––following Wittgenstein––as ultimately constituted by our ability to act in the world and demonstrate our primary engagement with the world. They are born out of our everyday experience of the world, conveying our direct, pre-reflective, and practical grasp of the world, rather than expressing judgments we make about it.• Similarly, the Background is defined as those abilities and dispositions that are neither representations nor rules, that function before we can make sense of our experiences.• Wittgenstein’s Bedrock and Searle’s Background in great part overlap with Blankenburg’s pre-reflective natural self-evidence and Stanghellini’s common sense, namely, our own unreflecting know-how, a set of nonpropositional skills, capacities, and dispositions that attune us with the world.• Without a fully functioning Background, the distinctions between imaginary and real (mind and world), self and non-self, and cause and coincidence fail to be adequately drawn within experience. Also, grasping the meaning of others’ behaviors and a weakening of contextual influences are entailed by an erosion of Background sensibilities.I feel extremely sympathetic to this account and, as Rhodes and Gipps report, there are remarkable points of overlap between their and my own ideas about the formation of schizophrenic delusions. I would like to add some comments on the main theories on the basic disorders entailed in the pathogenesis of delusions and conclude with some suggestions to integrate the Background theory of delusions. [End Page 311]Syntagmatic Versus Paradigmatic Models of DelusionsLet me raise first an epistemological point: paradigmatic models of delusions––defining what a delusion is in itself and what are its borders with similar phenomena––proved to be unsatisfactory in psychopathology. As Schneider and Huber (1975) put it more that 40 years ago, “[w]hat counts in delusions is not the delusion itself... but snagging the course of the lived experience, rather than its product” (p. 2042). What we do need, to understand what delusions really are, are syntagmatic models how––delusions (in this case, delusions in persons with schizophrenia) are connected to other phenomena within a structure or a process. What we should look for, then, are the phenomena that contribute as motivationally (or causally) necessary vulnerability, that is, the basic disturbance for the development of delusions. This logically implies that we need studying delusions in fieri, or the pathways that lead to delusions themselves. I subscribe to the principle that studying delusion by merely concentrating exclusively on its crystallized forms would be like studying stroke victims to know more about hypertension (Parnas and Sass 2001). This methodological move from crystallized delusions to delusions in-the-making is quintessential to define the subtle, basic, phenomenal invariant core that characterizes a given psychopathological phenomenon and that emerges across the manifold facets of the phenomenon itself and shapes them and keeps them meaningfully interconnected.A syntagmatic model should account for (at least) the following features of schizophrenic delusions:• abnormalities in symbolization (loss of commonsense meaning of a given thing or fact),• formal aspects (e.g., revelation character, experience of centrality), and• specificity of content (e.g., metaphysical tinge).It should also be compatible with those phenomena like self-disorders (loss of sense of ownership and of agency) that are entailed in most schizophrenic symptoms (e.g., verbal–acoustic hallucinations and experiences of alien control). Finally, it should keep meaningfully... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Psychodramatic Psychotherapy for Schizophrenic IndividualsJohn Nolte, MD, PhD (bio)As a long-time student, practitioner, trainer, author and advocate of J. L. Moreno, MD,’s works and specifically the psychodramatic method, I am always appreciative of efforts, like Chapy’s, to commend and advocate for psychodrama. This is especially so because for a time, Moreno and psychodrama were heavily criticized, even maligned in the mental health professions. At the same time, considering how (...) poorly Moreno and his methods have been understood as well as the difficulty of accessing his original material, I feel an obligation to set the record straight when confronted with incomplete, inadequate, or sometimes incompetent expositions of Moreno’s psychodrama.Chapy’s article recommends psychodrama as a treatment method for schizophrenic people by calling upon existentialist and phenomenological concepts. Psychodrama, he proposes, opens up existence by allowing “schizophrenic patients to incorporate the experience of an ‘absolutely other.’”There are major flaws in Chapy’s presentation. His “clinical illustration,” the presentation of a psychodrama with a schizophrenic patient, while it may be considered psychodrama under the broadest definition of the term, hardly fulfills the requirements of a psychotherapeutic psychodrama. We must question the competence of the psychodramatist in Chapy’s example. Chapy’s description of the drama itself falls short of being an adequate account of a psychodrama, failing to convey the emotional intensity and realness which a well directed and reported psychodrama achieves. We do not learn, for example, if Damien’s perception of his father is introduced through role reversal with the father, a standard psychodramatic technique which is done in order to give the auxiliary ego taking that role an understanding how Damien experiences his father. We do not know if role reversals are made throughout the drama so that Damien can experience how he is perceived by father, can feel the force of his confrontation in the role of father, and is required to reply as his father to his confrontation. We are given little information about the psychodramatic techniques employed by the director other than the scene setting of the studio in which the psychodramatic [End Page 227] encounter takes place, and the soliloquy in which Damien expresses his worry and hopes for the outcome of the confrontation. It should be clear in the description of the drama whether the father’s statements in the drama were produced by Damien in role reversal, or by the auxiliary ego playing the role. There is a difference and it is significant. Although we are told that Damien “evokes a systematic relationship between him and his father” during the psychodrama, we do not see how this happens. Every psychodrama is an existential experience and its description should fully communicate its meaning and emotion.A more serious problem, however, is that this drama does not deal with Damien’s psychosis. Although Damien may be diagnosed as schizophrenic, his disorder is obviously in remission or controlled by psychotropic drugs. The drama reveals none of the hallucinations, delusions, or disorder characteristic of schizophrenic disorders. It could be psychodrama of any young man with a complaint about his father.The notion that people with schizophrenia can be successfully treated by psychodrama is not new. Moreno began developing psychodramatic psychotherapy at his Beacon Hill Sanitarium, established in 1936. He and psychodrama gained some fame because of his success in treating schizophrenic patients at a time when schizophrenic individuals were considered incapable of benefitting from psychotherapy. Moreno’s approach to the treatment of schizophrenic patients was much more robust than the psychodrama described by Chapy. During a psychotic attack, the individual’s perception of the world and self are distorted in ways that made action and interaction in the world of conventional reality impossible. Additionally, the psychotic episode makes the psychotic person incapable of being comprehended by anyone else, including the psychiatrist. Moreno’s solution was to make the chaotic, bewildering, sometimes violent and always terrifying inner world visible and tangible in the surplus reality of the psychodramatic stage. In moments of lucidity following the psychotic episode, he asked his schizophrenic patients to reenact their psychotic experiences. The result was that, “In this imaginary reality on the psychodramatic stage, the... (shrink)

Individuals with Parkinson’s disease and temporal lobe epilepsy have hallucinations and mild cognitive dysfunction. The objective of this work was to study dreams in PD and TLE patients using a common functional model of dream production involving the limbic and paralimbic structures.Dreams were characterised in early-stage PD and TLE patients with dream diaries classified by the Hall van de Castle system and were compared with matched controls.In PD, there were significant differences between patients’ dreams and those of controls: animals, physical (...) aggression, and a befriender were more common in patients, and aggressor and bodily misfortunes were less common. The dreams of patients with frontal dysfunction showed more aggressive features.TLE patients had lower recall than PD patients and a higher proportion of dreams involving family and familiar settings, lower proportions involving success, and a higher incidence of frontal dysfunction.The dreams of PD and TLE patients share important features.

In lieu of an abstract, here is a brief excerpt of the content:Ethics CommentaryNeil Pickering, Senior LecturerThe underlying problem for Mr. T’s doctors and his wife is that Mr. T seems unable for much of the time to realise that he is ill. This gives his doctors and other mental health workers, and indeed his wife, very little room for manoeuvre with him. His illness apparently makes him dangerous, because of his beliefs that others are involved in conspiracies against him, (...) which seem to arise from his condition, and this danger particularly affects his wife who has been subject to threats by Mr. T. The initial question is whether Mr. T’s doctors should support or collude in Mrs. T’s proposal to medicate her husband surreptitiously — and if not, what is the alternative? A no less important question is how Mrs. T’s safety might be assured. Underlying these issues is a wider question about the relation between the mentally ill and their doctors, relations (partners and other family members) and society. Mr. T’s behaviours threaten to isolate him from his loved ones and from society.Presumably, Mrs. T’s hope is that giving Mr. T medication will keep his symptoms under control, ensuring her safety and enabling him to retain his relationship with her and perhaps with others; in short, maintaining his place in society. There is also strong evidence that a delay in psychiatric treatment is related to poorer outcomes in terms of, for example, increased morbidity.1 Moreover, some form of long-term medication does seem to be the main hope of achieving a desirable outcome in Mr. T’s case. It seems from the case description that some control of Mr. T’s symptoms results from his taking his medication, and his return to delusions comes only when he gives up on it. It is not made clear, however, why he does give up on it. [End Page 212]From the description of Mr. T, one gets the strong impression of behaviours dominated by the command hallucinations and the paranoid delusions that seem to gather around them. However, there are also, perhaps, periods where other motivations and beliefs have some grip on his life. We are told he has a job, and of course he has the relationship with his wife. What seems to happen is that, at least as far as the latter goes, when his illness reasserts itself, the meaning of his wife’s relationship to him becomes changed in his mind, and Mrs. T becomes part of the conspiracy he believes aims to kill him.Nonetheless, it is unacceptable for Mr. T’s doctors to support Mrs. T’s plan or to collude in it. The primary reason for this is not that it will be a potential disaster — though it stands a good chance of failing and going terribly wrong. There may be dangers to those who administer covert medication if discovered by a paranoid patient in addition to dangers for Mr. T who may misinterpret the side effects of the drugs he is unaware he is taking, or take other drugs that may interact with the drug he is receiving covertly.2 The primary objection to psychiatrists’ colluding in this is that using a third person to surreptitiously deliver medication to Mr. T is to betray his trust in the medical profession, and that this is unacceptable.Mr. T seems to have at best an ambivalent relationship with the medical profession. He seems unable to develop any long-term trust in them, and after a short time off his medication, any trust he may have developed disappears and he turns to his own judgement as to whether he is ill or not, ignoring the advice of his psychiatrist. The trust that the medical profession enjoys from patients is partly responsible for giving it its authority over their actions; and is partly why doctors and other health workers are offered great access to details about a person’s private life. Since this is so basic to the success of the doctor-patient relationship, but is also rather fragile, it is incumbent upon doctors to seek to retain their patients’ trust.So, in the usual situation, the patient and doctor...

Black Mirror is full of technologies that manipulate people's sensory perceptions. Philosophers of perception explain that our brains actively construct what we sense based on previous knowledge, expectations, and emotions, without us even being aware of this framing. Many Black Mirror episodes illustrate the mistakes that people can make when they misunderstand this framing process. Some episodes suggest that highly effective virtual reality technology could foil the strategies that Descartes recommended for distinguishing hallucinations and dreams from reality. Yet other episodes (...) warn how powerful institutions can punitively wield the power of control over perception. Yet in rare optimistic moments, Black Mirror demonstrates the value of relying on the help of other people to hold firm to deeper truths in the face of forces that would manipulate us. [Or, a slightly longer version with key episode titles: Black Mirror is full of technologies that manipulate people's sensory perceptions. Philosophers of perception explain that our brains actively construct what we sense based on previous knowledge, expectations, and emotions, without us even being aware of this framing. Video playback of perceptions, as in Arkangel, illustrate the mistakes that people can make when they misunderstand this framing process. Playtest and Bandersnatch suggest that highly effective virtual reality technology could foil the strategies that Descartes recommended for distinguishing hallucinations and dreams from reality. In the hands of government, law enforcement, and the military, the total control of perception can be wielded as tool for punishment, as in Men Against Fire and White Bear. But in more optimistic moments, such as at the conclusions of Nosedive and San Junipero, Black Mirror demonstrates the value of relying on the help of other people to hold firm to deeper truths in the face of forces that would manipulate us.].

Historia, as both a type of critical inquiry and a source of information about nature and the human world, is a key category in Spinoza’s Tractatus theologico-politicus. In this work, the Latin word cannot be simply and invariably translated as “history,” not even if we add the proviso that its meaning wavers inevitably between “history” and “story,” for its semantic range is too broad and complex. At the two ends of the semantic spectrum we have the impartial report, on the (...) one hand, and the creations of sheer fantasy, on the other. Historia may therefore denote the detached observation of nature and the philological analysis of a text, but it can also refer to the free exercise of the imagination in a variety of narrative contexts. While Spinoza denies that the inquiry resulting from historia and its products may have true cognitive value, he acknowledges that historia plays a fundamental role in society and politics. The reason is that historia and the imagination are bound up together by a special relationship. This is apparent at all levels of the historical engagement with reality, but is particularly true in the case of religion, moral norms and belief systems, for in this variegated domain the link between imagination and historia functions as the connective tissue that keeps societies united and functioning. This specific nexus of imagination and historia is Spinoza’s original contribution to the early modern notion of “moral certainty.” More importantly, it is only at this level that Spinoza grants a modicum of intelligibility to the ‘historical’ productions of the imagination, be they signa, revelationes, or even nugae. The fact remains, though, that to a certain extent humans keep having a distorted grasp of reality, indeed hallucinate, even when their ‘historical’ accounts of reality are socially and politically productive. Here the key element is the notion of fictional continuity based on a socially constructed trust in narrative accounts of reality: the imagination turns reality into stories, but in so doing it keeps the otherwise constitutively hallucinatory nature of humans at bay and under control. Perceptibilitas, that is, the ability to provide acceptable cognitive solutions between intelligible knowledge and moral certainty, is ultimately what defines the contribution of the imagination to the human work of knowledge.

Scientific and philosophical perspectives on hallucination: essays that draw on empirical evidence from psychology, neuroscience, and cutting-edge philosophical theory.

When one visually hallucinates, the object of one’s hallucination is not before one’s eyes. On the standard view, that is because the object of hallucination does not exist, and so is not anywhere. Many different defenses of the standard view are on offer; each have problems. This paper defends the view that there is always an object of hallucination—a physical object, sometimes with spatiotemporally scattered parts.

A natural starting point for theories of perceptual states is ordinary perception, in which a subject is successfully related to her mind-independent surroundings. Correspondingly, the simplest theory of perceptual states models all such states on perception. Typically, this simple, common-factor relational view of perceptual states has received a perfunctory dismissal on the grounds that hallucinations are nonperceptual. But I argue that the nonperceptual view of hallucinations has been accepted too quickly. I consider three observations thought to support the view, and (...) argue that all three are dealt with equally well by an alternative view, illusionism, on which hallucinations do involve perception. Since this is so, adopting a common-factor relational view of all perceptual states remains a tenable option. (shrink)

In Real Hallucinations, Matthew Ratcliffe offers a philosophical examination of the structure of human experience, its vulnerability to disruption, and how it is shaped by relations with other people. He focuses on the seemingly simple question of how we manage to distinguish among our experiences of perceiving, remembering, imagining, and thinking. To answer this question, he first develops a detailed analysis of auditory verbal hallucinations (usually defined as hearing a voice in the absence of a speaker) and thought insertion (somehow (...) experiencing one's own thoughts as someone else's). He shows how thought insertion and many of those experiences labeled as "hallucinations" consist of disturbances in a person's senseof being in one type of intentional state rather than another. Ratcliffe goes on to argue that such experiences occur against a backdrop of less pronounced but wider-ranging alterations in the structure of intentionality. In so doing, he considers forms of experience associated with trauma, schizophrenia, and profound grief. The overall position arrived at is that experience has an essentially temporal structure, involving patterns of anticipation and fulfillment that are specific to types of intentional states and serve to distinguish them phenomenologically. Disturbances of this structure can lead to various kinds of anomalous experience. Importantly, anticipation-fulfillment patterns are sustained, regulated, and disrupted by interpersonal experience and interaction. It follows that the integrity of human experience, including the most basic sense of self, is inseparable from how we relate to other people and to the social world as a whole. (shrink)
