BACKGROUND Psychotic phenomena appear to form a continuum with normal experience and beliefs, and may build on common emotional interpersonal concerns. AIMS We tested predictions that paranoid ideation is exponentially distributed and hierarchically arranged in the general population, and that persecutory ideas build on more common cognitions of mistrust, interpersonal sensitivity and ideas o...

BACKGROUND The ability to inhibit inappropriate or unwanted actions is a key element of executive control.

Schizophrenia and autism both feature significant impairments in social cognition and social functioning, but the specificity and mechanisms of these deficits remain unknown. Recent research suggests that social cognitive deficits in both disorders may arise from dysfunctions in the neural systems that underlie social cognition. We explored the neural activation of discrete brain regions implic...

BACKGROUND AND OBJECTIVES Psychological models have implicated negative self-esteem as an important factor underlying paranoia. However, research investigating the role of self-esteem in paranoia suffers from poor conceptual and methodological understanding, resulting in conflicting findings. Central to this problem is the use of measures investigating global self-esteem and self-evaluative bel...

Nonetheless, the two experiences are distinct. The aim of this study was to identify factors that distinguish the occurrence of social anxiety and paranoid thoughts in an experimental situation. METHOD Two hundred non-cli...
