“…These two forms of treatment have, to date, had distinct aims. The recent demonstrations of success of cognitive behavioral treatment for symptoms such as hallucinations and delusions is impressive (Dickerson 2000;Pilling et al 2002). Thus far, however, there have been no studies which have looked at the neuropsychological effects of cognitive behavior therapy for schizophrenia.…”

Cognitive neuroscience provides a new conceptual framework for psychiatry by showing how psychological processes arise from neuronal activity (Kandel 1998). Conversely, it is possible that psychiatry will influence the future development of cognitive neuroscience by encouraging a better balance between localist and holistic conceptions of brain function. An apparent conflict between these conceptions has been central to the development of neuroscience, with the emphasis upon locally specialized functions emerging as clearly dominant. Neuroanatomy, neurophysiology, neuropsychology, and neuroimaging all show that different regions of the brain process information about different things, and that different cells within regions deal with different aspects of those things. Recent developments in experimental and theoretical neurobiology, however, are leading to an increased emphasis upon interactions that coordinate the activity of locally specialized processors. Here we argue that impairment of these coor-BEHAVIORAL AND BRAIN SCIENCES (2003) Abstract:The concept of locally specialized functions dominates research on higher brain function and its disorders. Locally specialized functions must be complemented by processes that coordinate those functions, however, and impairment of coordinating processes may be central to some psychotic conditions. Evidence for processes that coordinate activity is provided by neurobiological and psychological studies of contextual disambiguation and dynamic grouping. Mechanisms by which this important class of cognitive functions could be achieved include those long-range connections within and between cortical regions that activate synaptic channels via NMDAreceptors, and which control gain through their voltage-dependent mode of operation. An impairment of these mechanisms is central to PCP-psychosis, and the cognitive capabilities that they could provide are impaired in some forms of schizophrenia. We conclude that impaired cognitive coordination due to reduced ion flow through NMDA-channels is involved in schizophrenia, and we suggest that it may also be involved in other disorders. This perspective suggests several ways in which further research could enhance our understanding of cognitive coordination, its neural basis, and its relevance to psychopathology.Keywords: attention; cerebral cortex; cognitive coordination; cognitive neuropsychiatry; cognitive neuropsychology; context disorganization; Gamma rhythms; Gestalt theory; glutamate; grouping; memory; NMDA-receptors; PCP-psychosis; perceptual organization; schizophrenia William A.

“…This ap roach is premised in the idea that delusions are a type of belief (Alford and Beck, 1994). One of the main technics of CBT consists in questioning the patient's delusional belief in light of counterevidence (Dickerson, 2000). CBT has been proven effective in the treatment of some delusions and such effectiveness can be accounted by the fact that delusions are sometimes responsive to counterevidence (Garety et al, 1997) 11 .…”

The typology problem and the doxastic approach to delusions

This paper explores one of the most fundamental philosophical worries underlying the occurrence of delusions, namely, the problem about the specific type of mental state that grounds a delusional report or, as I shall call it, 'the typology problem'. The analysis is developed as follows: (i) After formulating and circumscribing the target problem, (ii) I explore the main tenets and advantages of the doxastic view of delusions, perhaps, the strongest candidate currently available within the typology debate. (iii) After, I clarify and evaluate four of the main counter-arguments against the doxastic view offering a number of counter replies to these attacks. (iv) Finally, I conclude that the anti-doxastic argumentation offers no good reasons to abandon the doxastic model and that this model does not need to appeal to external resources to reply to such counter-arguments. At the same time, I finalize with some of the challenges that remain open within the doxastic view.Keywords: psychosis, delusions, doxastic view of delusions, typology problem. RESUMOEsse artigo explora uma das preocupações filosóficas mais fundamentais que subjazem à manifestação de delírios, a saber, o problema do tipo específico de estado mental que fundamenta um relato de delírio -o que chamarei de 'problema tipológico'. A análise empreendida é desenvolvida do seguinte modo: (i) Após formular e circunscrever o problema-alvo, (ii) exploro os principais comprometimentos e vantagens da explicação doxástica dos delírios, que é talvez a mais forte dentre as soluções propostas dentro do debate tipológico. (iii) A seguir, esclareço e avalio quatro dos principais argumentos contra a explicação doxástica, oferecendo réplicas a esses ataques. (iv) Finalmente, concluo que a argumentação anti-doxástica não oferece boas razões para abandonarmos o modelo doxástico e argumento que esse modelo não precisa apelar a recursos externos para responder aos argumentos anti-doxásticos. Termino o artigo expondo alguns desafios ao modelo doxásti-co que permanecem em aberto.Palavras-chave: psicose, delírios, visão doxástica de delírios, problema tipológico.

“…As a motivation, they cite matters of practical importance such as the implications that theoretical speculation has for the treatment of delusions. They refer to cognitive behavioral therapy (CBT), an important form of therapy for delusions (Dickerson 2000), one of the essential components of which involves questioning the consistency and plausibility of the patient's delusions (Chadwick, Brichwood and Trower 1996). This form of therapy, they argue, seems to accord with the doxastic account, in that the therapist treats the delusional patient as a believer of p and gently invites the patient to question the delusional belief.…”

Can dispositionalism about belief vindicate doxasticism about delusion?

Abstract. Clinical delusions have traditionally been characterized as beliefs in psychiatry. However, philosophers have recently engaged with the empirical literature and produced a number of objections to the so-called doxastic status of delusion, stemming mainly from the mismatch between the functional role of delusions and that expected of beliefs. In response to this, an appeal to dispositionalism about the nature of belief has been proposed to vindicate the doxastic status of delusion. In this paper, I first present the objections to attributing beliefs to delusional patients and the application of dispositionalism in the attempt to vindicate doxasticism. I then assess this application and some responses to the objections to the doxastic characterization. Finally, I offer some conclusions about the limits of folk-psychological concepts in the characterization and explanation of complex psychological phenomena such as delusions.
