BACKGROUND Our approach to advancing the treatment of psychosis is to focus on key single symptoms and develop interventions that target the mechanisms that maintain them. In our theoretical research we have found worry to be an important factor in the development and maintenance of persecutory delusions. Worry brings implausible ideas to mind, keeps them there, and makes the experience distres...

Mirrored-self misidentification is the delusional belief that one’s own reflection in the mirror is a stranger. Current theories suggest that this delusion can occur when two factors are present: a deficit in face processing which is responsible for the content of the delusion (Factor 1) and a deficit in belief evaluation which accounts for the failure to reject the delusional belief (Factor 2)...

The present study investigated the relationship between delusion proneness, as assessed using the Peters et al. Delusions Inventory [Peters, E.R., Joseph, S.A., Garety, P.A., 1999. The measurement of delusional ideation in the normal population: Introducing the PDI (Peters et al. Delusions Inventory). Schizophr. Bull. 25 553-576], and cognitive insight, as assessed using the Beck Cognitive Insi...

Erotomania is the delusional belief that one is loved from afar by another person (the target). This study used hypnosis as a novel cognitive neuropsychological research tool to model erotomania. The authors developed 2 versions of a hypnotic erotomania suggestion and tested their impact by asking subjects to recall and interpret a story featuring ambiguous scenarios. They also challenged the d...

Delusion is usually considered in DSM 5 as a false belief based on incorrect inference about external reality, but the issue of delusion raises crucial concerns, especially that of a possible (or absent) continuity between delusional and normal experiences, and the understanding of delusional experience. In the present study, we first aim to consider delusion from a perspectivist angle, accordi...

Introduction The early diagnostic of schizophrenia and other psychosis is very important for the therapeutic interventions. Objectives aim to describe connection between prodromal stage clinical features. Methods 74 patients with late-onset (mean age 64,33±9, 2 male; onset 55,3±11,2): (LOS) (n=49, mean 63,0±8,47, 53,9±9,56), schizoaffective disorder (LOSaD) (n=17, 62,4±6,5, 54,6±10,6, male), la...

The authors suggested a change of sex to virtuoso, high-hypnotizable, and low-hypnotizable simulating participants in an application of the real-simulating paradigm of hypnosis. The experiences of sex change that participants reported during hypnosis were challenged through procedures of contradiction and confrontation. Behavioral and self-report data indicated that virtuosos experienced a tran...

OBJECTIVE To examine the social cognitive vulnerabilities mediating delusion formation in children presenting with hallucinatory experiences. METHOD A sample of 259 12- and 13-year-old children, from a baseline case-control sample of children with and without auditory hallucinations (AH), were re-assessed after 5 years for presence of AH. Presence of delusions and theory of mind (ToM) were al...

The study of delusions has important implications for understanding the role played by affective processes on the road from experience to belief. It can also shed light on the forms of modularity these processes manifest. There are at least two different ways in which emotional processes may be relevant to the etiology of delusional beliefs. First, current models of delusion converge in proposi...
