Paranoid and teleological thinking give rise to distinct social hallucinations in vision.
Commun Psychol

Yale University, New Haven, CT, USA.
Paranoia (believing others intend harm) and excess teleological thinking (ascribing too much purpose) are non-consensual beliefs about agents. Human vision rapidly detects agents and their intentions. Might paranoia and teleology have roots in visual perception? Using displays that evoke the impression that one disc ('wolf') is chasing another ('sheep'), we find that paranoia and teleology involve perceiving chasing when there is none (studies 1 and 2) - errors we characterize as social hallucinations.

Objective: To develop a systematics of chronic delusional psychoses in schizophrenia and pathology of the schizophrenic spectrum that takes into account psychopathological structure (the mechanism of delusional formation) and the trajectories of the disease course (the ratio of negative/positive dimensions).
Material And Methods: The study sample was recruited from the large Moscow psychiatric hospital in 2019-2024 and included 126 patients (94 male, 32 female, mean age 36.5±12.

Article Synopsis
- - The study explores the connections between dimensional psychopathological syndromes and brain structure/function in patients with Major Depressive Disorder, Bipolar Disorder, Schizoaffective Disorder, and Schizophrenia, analyzing data from 1,038 individuals.
- - Researchers identified three main psychopathological factors—paranoid-hallucinatory syndrome, mania, and depression—and found significant brain volume and cortical thickness differences linked to the paranoid-hallucinatory syndrome.
- - Genome-wide association studies revealed significant genetic associations for mania and depression, suggesting a need for more dimensional perspectives in psychiatric classifications to improve understanding and treatment.

Decreased sleep spindle activity in individuals with psychotic disorders is well studied, but its contribution to psychotic symptom formation is not well understood. This study explored potential underlying mechanisms explaining the association between decreased sleep spindle activity and psychotic symptoms. To this end, we analysed the links between sleep spindle activity and psychotic experiences and probed for the mediating roles of attentional performance and perceptual distortions in a community sample of young adults (N = 70; 26.

Introduction: The Attenuated Psychosis Symptoms (APS) syndrome mostly represents the ultra-high-risk state of psychosis but, as does the Brief Intermittent Psychotic Symptoms (BIPS) syndrome, shows a large variance in conversion rates. This may be due to the heterogeneity of APS/BIPS that may be related to the effects of culture, sex, age, and other psychiatric morbidities. Thus, we investigated the different thematic contents of APS and their association with sex, age, country, religion, comorbidity, and functioning to gain a better understanding of the psychosis-risk syndrome.
