Hodological resonance, hodological variance, psychosis, and schizophrenia: a hypothetical model.

Schizophrenia is a disorder with a large number of clinical, neurobiological, and cognitive manifestations, none of which is invariably present. However it appears to be a single nosological entity. This article considers the likely characteristics of a pathology capable of such diverse consequences.

Time perception and its neuropsychological correlates in patients with schizophrenia and in healthy volunteers.

Disordered time perception has been reported in schizophrenia. We investigated time perception dysfunction and its neuropsychological correlates in patients with schizophrenia. Participants comprised 38 patients and 38 age- and sex-matched healthy volunteers who were compared in an auditory temporal bisection paradigm using two interval ranges (a 400/800 ms condition and a 1000/2000 ms condition).

Voice familiarity engages auditory cortex.

Familiarity with a speaker's voice has been shown to enhance its auditory processing, implicating physiological effects at the level of the auditory cortex, although auditory cortical involvement has not previously been demonstrated. Eleven healthy right-handed male participants performed two tasks during blood oxygenation level-dependent functional MRI at 1.5 T.

Clinical and service implications of a cognitive analytic therapy model of psychosis.

Cognitive analytic therapy (CAT) is an integrative, interpersonal model of therapy predicated on a radically social concept of self, developed over recent years in the UK by Anthony Ryle. A CAT-based model of psychotic disorder has been developed much more recently based on encouraging early experience in this area. The model describes and accounts for many psychotic experiences and symptoms in terms of distorted, amplified or muddled enactments of normal or 'neurotic' reciprocal role procedures (RRPs) and of damage at a meta-procedural level to the structures of the self.
