The cognitive antecedents of psychosis-like (anomalous) experiences: variance within a stratified quota sample of the general population

摘要: In the general population, psychosis-like experiences have been extensively studied under psychometric rubric of schizotypy (psychosis-proneness). As such, Phase 1 this thesis aimed to assess distribution schizotypal traits and associated personality correlates displayed within a quota sample population stratified by Gender Ageband, emphasis being upon anomalous (positive schizotypy). Respondents (N = 130) completed battery established self-report measures assessing thirteen areas personal experience. Correlational analysis revealed that eleven ostensibly possessed significant intercorrelations. Subsequent principal components identified three factors accounting for 64.91% total variance; factor greatest proportion variance (42.97%) was interpreted as representing psychological disposition towards reporting ‘Anomalous Cognitions’. The other two are named ‘Lifeview System’ (12.60% variance) ‘Social Adaptation Skills’ (9.34% variance). From inclusion criteria 2 research explicated. No mean differences were six provided unique contributions toward cognitions, uniquely contributed lifeview system, or single measure social adaptation skills. Additionally, four nine which factorial generated between Agebands, with further providing trends differences.

A comprehensive literature review highlighted domains cognition, five accompanying measures, intelligence functioning (verbal fluid/visuoconstructive), which, following previous research, utilised covariate measures. Based on prescribed delineation points, allocated, according scores from 1, one (low-, mid, high-anomalous cognitions). Of domains—1) sustained visual attention; false (illusory) memory; probability reasoning (decision making); 4) object recognition; 5) reality monitoring; 6) self-monitoring—four succeeded in eliciting noted exceptions attention self-monitoring. canonical discriminant analyses predictors XPG membership number critical lures recognised memory test, correct responses confidence when uncertain recognition plus pertaining comorbid psychopathology vividness imagery. light fasle biases, comorbidity mental pathology (especially, depressive anxiety-related symptoms), imagery unsurprising; however, variables (the ‘number responses’ ‘confidence uncertain’) offer exciting avenues future into continuum psychosis.
