Experiences of thought-insertion are a first-rank, diagnostically central symptom of schizophrenia. Schizophrenic patients who undergo such delusional mental states report being first-personally aware of an occurrent conscious thought which is not theirs, but which belongs to an external cognitive agent. Patients seem to be right about what they are thinking but mistaken about who is doing the thinking. It is notoriously difficult to make sense of such delusions. One general approach to explaining the etiology of monothematic delusions has come to (...) be known as the endorsement model. This model claims that the patient holds her delusional belief because she simply trusts her bizarre experience and takes it at face value. The content of the bizarre experience thus plays a central role in the etiology of delusions. Despite being widely discussed with respect to delusions like Capgras and Cotard, an endorsement model of thought-insertion has not yet been formulated. This article seeks to fill this void by fleshing out and defending the endorsement approach to delusions of inserted thoughts. It aims to show that such an approach can be defended against objections that have been raised in the literature. In particular, it will be argued that there is nothing wrong with the idea of being first-personally aware of a thought which is presented in consciousness as being someone else's. The upshot is that with respect to delusions of thought-insertion, the endorsement model turns out to be a viable account of why patients come to believe that someone else is inserting thoughts into their minds.

Stephens and Graham maintain that in cases of thought insertion, the sense of ownership is preserved, but there is a defect in the sense of agency. However, these theorists overlook the possibility that subjectivity might be preserved despite a defect in the sense of ownership. The claim that schizophrenia centers upon a loss of a sense of ownership is supported by an examination of some of the other notable disownership symptoms of the disorder, such as bodily alienation and experiences of (...) “unworlding.” Is there a way to make sense of the “underlying characteristic modification” that ties together the various symptoms of schizophrenia and disrupts subjects’ “hold” on their own bodies and surroundings? I will argue that what accounts for subjects’ usual sense of ownership are fully embodied processes of causal-contextual information integration, which are made possible by subjects’ affective framing patterns. Attenuated affective framings lead to a loss of a sense of ownership and cause subjects to lose their “grip” on bodily sensations and mental states, which ultimately can result in experiences of thought insertion. I will conclude with some brief remarks about implications for treatment, and point to several body-centered intervention methods that might help to restore subjects’ sense of ownership. (shrink)

RésuméLes philosophes et les scientifiques présument en général que la conscience est caractérisée par « un point de vue à la première personne ». Selon une interprétation de cette revendication, les expériences sont définies, au moins en partie, par des représentations qui encodent un « point de vue » centré sur le sujet. Par contre, les revendications sur les caractéristiques déterminantes de la conscience doivent être attentives à la possibilité d'une dissociation : si une structure neurobiologique ou une fonction psychologique (...) n'est pas nécessaire ni suffisante pour la conscience, elle ne peut pas être un attribut distinctif dans un sens robuste. Je fais appel à la recherche sur l’émotion inconsciente, l'action guidée par la perception, la constance perceptuelle et les troubles psychiques pour soutenir que les représentations à la première personne dissocient de l'expérience consciente.

Despite the diagnostic relevance of thought insertion for disorders such as schizophrenia, the debates about its aetiology are far from resolved. This paper claims that in paying exclusive attention to the perceptual and cognitive impairments leading to delusional experiences in general, current deficit approaches overlook the role that affective disturbances might play in giving rise to cases of thought insertion. In the context of psychosis, affective impairments are often characterized as a consequence of the stress and anxiety caused by delusional (...) episodes. However, here I explore some of the conceptual and empirical reasons to think that affective problems might in fact play a crucial doxastic role in the aetiology of thought insertion. Finally, I conclude by proposing a way of integrating the main insights of my analysis with the current ‘two-factor’ deficit approach to thought insertion and I explore the potential adaptive role that some delusions might have within this framework.

RESUMEN Una atribución de agencia mental es definida como el acto de asignar el inicio o autoría de un pensamiento en primera persona a un agente específico, esto, con el fin de generar grados suficientes de control sobre nuestra vida cognitiva. Si bien esta estrategia es fundamental para distinguir diferentes tipos de estados cognitivos - tales como deliberaciones, razonamientos, juicios, entre otros -, muchos autores han indicado que también es clave para entender experiencias cognitivas psicopatológicas en psicosis. Este artículo revisa (...) la forma en que la estructura subjetiva de los delirios de inserción de pensamiento puede ser utilizada como una estrategia para evaluar los méritos argumentativos de las teorías que intentan explicar la arquitectura y naturaleza de las atribuciones de agencia mental. Luego de evaluar algunos aspectos fundamentales de las dos teorías dominantes en la literatura actual, se sugiere que, a pesar de sus importantes aportes al desarrollo de la discusión, tales enfoques no poseen los recursos explicativos suficientes para lidiar con el desafío propuesto. ABSTRACT An attribution of mental agency is defined as the act of assigning the initiation or authorship of a first personal thought to a specific agent in order to generate sufficient degrees of control over our own cognitive life. Although this strategy is crucial to distinguish different types of cognitive states - such as deliberations, reasonings, judgements, among others -, a number of authors have suggested that it is also crucial to understand psychopathological cognitive experiences in psychosis. This paper explores the way in which the subjective structure of thought insertion can be used as a strategy to evaluate the merits of theories aiming at explaining the nature and architecture of attributions of mental agency. After examining some of the most fundamental aspects of the two dominant theories in current literature, I suggest that, despite the contributions made by such theories to the discussion, none of them is able to face the challenge in a plausible way.

On a widely held view, episodes of inner speech provide at least one way in which we become conscious of our thoughts. However, it can be argued, on the one hand, that consciousness of thoughts in virtue of inner speech presupposes interpretation of the simulated speech. On the other hand, the need for such self-interpretation seems to clash with distinctive first-personal characteristics that we would normally ascribe to consciousness of one’s own thoughts: a special reliability; a lack of conscious ambiguity (...) and incomprehensibility; and a sense of causal agency. I try to resolve this puzzle by proposing an account for the requisite self-interpretation of inner speech in terms of Bayesian probabilistic inference. Drawing on “perceptual loop” accounts of speech control, I argue that such interpretive probabilistic inferences are used for the control of inner speech, and that as a consequence of this function, they are biased toward the correct interpretations. I conclude by showing how this model can explain the first-personal characteristics of consciousness of one’s own thoughts. In the case of the sense of causal agency, the resulting explanation yields novel accounts for “audible thoughts” and thought insertion. (shrink)

By examining first-person descriptions of thought insertion I show that thought insertion is a complex and heterogeneous phenomenon. People experiencing this phenomenon have huge difficulty explaining what it is like due to the bizarre nature of the experience. Through careful analysis of first-person descriptions I identify some of the characteristics of thought insertion. I then briefly examine some of the philosophical literature regarding agency, ownership and thought insertion and conclude that the standard account of the basic characteristics of thought insertion (...) is inadequate when we consider the phenomenon as it is experienced. First person descriptions suggest that thought insertion is characterised by a lack of personal ownership and not simply by a loss of agency or authorship. This is an important factor that should inform research and therapeutic intervention. We cannot hope to arrive at appropriate therapeutic intervention or identify underlying neuronal mechanisms for the experience if we cannot say what the experience actually is. I further suggest that more analysis of first-person description is required for an improved account of the phenomenology of thought insertion. (shrink)
