Imperfect Cognitions

Today's post is by Patrizia Pedrini (University of Florence). Here she summarises her recent paper, “Rescuing the ‘Loss-of-Agency’ Account of Thought Insertion”, which appeared in Philosophy, Psychiatry, & Psychology in 2015. Every day we think hundreds of thoughts. We form opinions, hold beliefs, develop intentions, feel desires, emotions, sensations, entertain fantasies. All this thinking activity typically comes to our consciousness with a fundamental feature that seems as natural as the thinking it accompanies: our capacity for self-ascription of it. When we think a thought, we also self-ascribe that thought, and such capacity for self-ascription is routine, immediate, unproblematic. However, this is a capacity that can break down. There is a disorder, known as thought insertion , that occurs in people diagnosed with schizophrenia and related forms of mental illness, the puzzling feature of which appears to amount to the impairment of such capacity. The subject aff...

This post is by David Miguel Gray (pictured above), currently Assistant Professor of Philosophy at Colgate University and in the Spring of 2017 will be Assistant Professor of Philosophy at the University of Memphis. David’s research interests are in the philosophy of cognitive psychology (in particular cognitive psychopathology), as well as philosophy of mind, and philosophy of race and racism. In this post David will address some theoretical issues with n-factor accounts of monothematic delusions. This post, and his previous one , will draw on his recent paper ‘ Failing to self-ascribe thought and motion: towards a three-factor account of passivity symptoms in schizophrenia ’, published in Schizophrenia Research. Cognitive-level theories of monothematic delusions have become heavily discussed, significantly in part to the work of Max Coltheart, Robyn Langdon, and Martin Davies (e.g. see Davies and Coltheart 2000 , Davies et al. 2001 , Coltheart et al. 2007 , Coltheart 2013 ). T...

David’s research interests are in the philosophy of cognitive psychology (in particular cognitive psychopathology), as well as philosophy of mind, and philosophy of race and racism.  I n this post David provides an explanation of abnormal experiences and the inferential processes involved in delusions of thought insertion and alien control. Next week, he will address some theoretical issues with n-factor accounts of monothematic delusions. Both posts will be drawing from his recent paper ‘ Failing to self-ascribe thought and motion: towards a three-factor account of passivity symptoms in schizophrenia ’, published in Schizophrenia Research. In my article I focus on two commonly known passivity symptoms of schizophrenia: thought insertion and alien ...

This post is by  Shaun Gallagher  (pictured above). He is Lillian and Morrie Moss Professor of Philosophy at the University of Memphis. In this post he summarizes his recent article ' Relations between Agency and Ownership in the Case of Schizophrenic Thought Insertion ', published in the Review of Philosophy and Psychology. In a recent paper I offer a response to some philosophers who have raised objections to the idea that in schizophrenic delusions of control and thought insertion the problem is primarily with the sense of agency. Instead, they argue, it concerns the sense of ownership. Let me start by clarifying the distinction, because in fact it is a double distinction, or a distinction made on two levels. On the level of first-order, pre-reflective experience the distinction between sense of agency (SA) and sense of ownership (SO) can be seen in the contrast between voluntary and involuntary movement. In the latter case, for example, if some one pushes me from ...

This post is by Clara Humpston  (in the picture above), PhD student in the School of Psychology at Cardiff University. Her research focuses on the pathogenesis of psychotic symptoms and adopts a cognitive neuropsychiatric approach; by incorporating behavioural, neuroimaging, and phenomenological investigations, she aims to further contribute to a unified account of delusions and hallucinations.  Here she summarises her recent paper, co-written with Matthew Broome  (in the picture below), ' The Spectra of Soundless Voices and Audible Thoughts: Towards an Integrative Model of Auditory Verbal Hallucinations and Thought Insertion ', published in Review of Philosophy and Psychology . Thought insertion is currently described as a delusion and a first-rank symptom of schizophrenia, i.e. a false belief that the subject receives inserted, whereas auditory-verbal hallucinations (voices) are aberrant sensory perceptions in the absence of any external stimulus. Our paper s...

This post is by Gottfried Vosgerau  (pictured above), Professor of Philosophy at the University of Dusseldorf. Gottfried's research interests are in the philosophy and metaphysics of mind, neurophilosophy, and cognitive science. Here he summarises his recent paper, co-authored with Martin Voss , ' Authorship and Control over Thoughts ', published in Mind and Language.  While there is a considerable consensus that ownership and agency should be sharply distinguished for motor actions, the according distinction for thoughts (thinking actions) is much less agreed on. In our paper we argue that a distinction is needed between the mere occurrence of a thought in my stream of consciousness (thought ownership) and my being the 'source' of a thought (authorship). While it is a conceptual truth that all of my thoughts are mine in the sense of ownership, there are already many examples from (non-pathological) everyday life that this is not the case for authorship. How...

This post is by Pablo López-Silva , a PhD student in the Department of Philosophy at the University of Manchester. Pablo (pictured above) works on philosophical problems raised by schizophrenia, and is supervised by Joel Smith and Tim Bayne . Here Pablo summarises his recent paper ' Schizophrenia and the Place of Egodystonic States in the Aetiology of Thought Insertion ', published in Review of Philosophy and Psychology.  Paradigmatic cases of thought insertion involve the delusional belief with the content [someone/something is placing a thought with the content […] into my mind/head] (Mellor 1970 ; Mullins and Spence 2003 ). Despite the diagnostic relevance of this phenomenon, the debates about its aetiology are far from resolved. In this context, two projects can be distinguished. On the one hand, the motivational project characterizes thought insertion as resulting from the mind’s attempt to deal with highly stressing psychological conflicts. On the other hand, the ...
