In 1910, Karl Jaspers wrote a seminal essay on morbid jealousy in which he laid the foundation for the psychopathological phenomenology that through his work and the work of Hans Gruhle and Kurt Schneider, among others, would become the ...

William James gets very high on nitrous oxide and then writes about it.

In recent years, there has been much focus on the apparent heterogeneity of schizophrenic symptoms. By contrast, this article proposes a unifying account emphasizing basic abnormalities of consciousness that underlie and also antecede a disparate assortment of signs and symptoms. Schizophrenia, we argue, is fundamentally a self-disorder or ipseity disturbance that is characterized by complementary distortions of the act of awareness: hyperreflexivity and diminished self-affection. Hyperreflexivity refers to forms of exaggerated self-consciousness in which aspects of oneself are experienced as akin (...) to external objects. Diminished self-affection or self-presence refers to a weakened sense of existing as a vital and self-coinciding source of awareness and action. This article integrates recent psychiatric research and European phenomenological psychiatry with some current work in cognitive science and phenomenological philosophy. After introducing the phenomenological approach along with a theoretical account of normal consciousness and self-awareness, we turn to a variety of schizophrenic syndromes. We examine positive, then negative, and finally disorganization symptoms—attempting in each case to illuminate shared distortions of consciousness and the sense of self. We conclude by discussing the possible relevance of this approach for identifying early schizophrenic symptoms. (shrink)

The phenomenology of agency and perception is probably underpinned by a common cognitive system based on generative models and predictive coding. I defend the hypothesis that this cognitive system explains core aspects of the sense of having a self in agency and perception. In particular, this cognitive model explains the phenomenological notion of a minimal self as well as a notion of the narrative self. The proposal is related to some influential studies of overall brain function, and to psychopathology. These (...) elusive notions of the self are shown to be the natural upshots of general cognitive mechanisms whose fundamental purpose is to enable agents to represent the world and act in it.

It is well established by psychopathological research that disorders of self-experience are among the main features of schizophrenic prodromes in a pathogenetic sense. Disorders of the phenomenal self, as "lack of ipseity" (the vanishing of the feeling of being embedded in oneself and of distinctiveness between the self and the outer world) and "hyper-reflexivity" (the monitoring of one's own life entailing the tendency to objectify parts of one's own self in an outer space) are considered key phenomena of schizophrenic vulnerability. (...) In this paper, I argue that the analyses of the disorders of phenomenal self catch only some dimensions of schizophrenic vulnerability, since they mainly focus on the pathological changes in subjective experience of an isolated self and disregard the fact that the self is not purely personal. Because our existence is fundamentally tied to a social existence, the feeling of one's own self and the sense of "reality" of an experience are products of intersubjectivity and not only a private process based on introspection or reflexivity in which one is engaged in an idiosyncratic way. Building on, and extending, contributions of the phenomenological tradition, I attempt to demonstrate that intuitive attunement is the basic prerequisite for establishing one's sense of "reality" (feeling familiarly related to one's environment) and for establishing one's sense of "ipseity" (the sense of existing as a subject of awareness). In the last part of the paper, I show the importance of the concepts "lack of attunement" and "antagonomia" (the rejection of conventional knowledge and intuitive attunement, experienced as dangerous sources of loss of individuality) to establish a comprehensive theory of schizophrenic vulnerability. I finally discuss the implications of this view for empirical research and clinical management of schizophrenic vulnerability. (shrink)

The phenomenological approach to schizophrenia has undergone something of a renaissance in Anglophone psychiatry in recent years. There has been a proliferation of works that focus on the nature of subjectivity in schizophrenia and related disorders, and that take inspiration from the work of such German and French philosophers as Husserl, Heidegger, and Merleau-Ponty, and such classical psychiatrists as Minkowski, Blankenburg, and Binswanger (Rulf 2003; Sass 2001a, 2001b). This trend includes predominantly theoretical articles, which typically incorporate clinical material as well (...) as reviews of empirical and experimental findings in psychopathology. Some very recent examples (since 2000) are studies of .. (shrink)
