The overlap of autism spectrum disorder (ASD) and psychosis or schizophrenia disorders (SSD) has exposed problems central to conceptualising understanding co-morbidity in psychiatric disorders. In the present study, we demonstrate that a deep phenotyping approach aids clarification both overlapping diametrically opposed features ASD SSD on level trait facets. We first show negative disorganised...
Anhedonia, defined as dysfunction in the experience of pleasant emotions, is a hallmark symptom of the schizophrenia spectrum. Of interest, it is well documented that patients with schizophrenia, at least as a group, do not show reductions in their state experience of pleasant stimuli. However, there is emerging evidence to suggest that individuals with schizotypy--defined as the personality or...
In several prior studies, self-reported schizotypy has been documented to vary by gender, age, race/ethnicity, and measures of social engagement. In this study, undergraduate students participated in an online survey, and data from 825 students were used to examine sociodemographic characteristics and past mental health treatment history as predictors of 6 schizotypy measures. History of mental...
Previous research has suggested a relationship between dissociative tendencies and schizotypy. This study sought to extend the previous work in two fundamental respects. First, explicit cognizance was taken of the multidimensionality of both dissociative tendencies and schizotypy. Second, the study examined the possibility that the observed correlation between dissociative tendencies and schizo...
The current study looked at the overlap between dissociation and schizotypy and examined two potential sources from which this overlap might originate: fantasy proneness and traumatic distress. From a sample of 191 undergraduates, those scoring in the upper and lower quartile of the Dissociative Experiences Scale (DES) were selected. Next, the scores of these groups on well-established schizoty...
"Schizotypy" is a latent organization of personality related to the genetic risk for schizophrenia. Some evidence suggests that schizophrenia and schizotypy share some biological features, including a link to dopaminergic D2 receptor signaling. A polymorphism in the D2 gene (DRD2 rs1076560, guanine > thymine (G > T)) has been associated with the D2 short/long isoform expression ratio, as well a...
A bias against disconfirmatory evidence (BADE) has been observed in schizophrenia, and in the present study we evaluated whether this extends to a nonclinical sample scoring high on a schizotypy scale. Thirty-seven high and 32 low schizotypy healthy participants were sequentially presented with three sentences that increasingly disambiguated the true content of a delusion-neutral scenario and w...
The main goal of the present study was to examine the relationship between the schizotypy dimensions, emotional-behavioural problems and personality disorder traits in non-clinical general adolescent population. A total of 1455 participants (M=15.9years; S.D.=1.2) were administered the Oviedo Schizotypy Assessment Questionnaire (ESQUIZO-Q), the Strengths and Difficulties Questionnaire (SDQ) and...
The main purpose of this study was to further the understanding of schizotypy by investigating which of two schizotypy models best describes the construct. The quasi-dimensional model views schizotypy as related to psychological ill-health, whereas the fully dimensional model views schizotypy as fundamentally neutral. A schizotypy measure, the Oxford–Liverpool Inventory of Feelings and Experien...
Heterogeneity in the expression of schizotypy may arise from underlying dimensional processes or a taxonic population structure. In a 2-phase study, we tested the taxonicity of self-reported schizotypy within a general psychiatric sample (n = 109) and examined taxon validity by testing its association with clinical schizotaxia in follow-up subsamples. Taxometric analyses indicated a taxonic str...
