The current study sought to examine the underlying brain changes in individuals with high schizotypy by integrating networks derived from brain structural and functional imaging. Individuals with high schizotypy (n = 35) and low schizotypy (n = 34) controls were screened using the Schizotypal Personality Questionnaire and underwent brain structural and resting-state functional magnetic resonanc...

INTRODUCTION Correlational methods, unlike cluster analyses, cannot take into account the possibility that individuals score highly on more than one symptom dimension simultaneously. This may account for some of the inconsistency found in the literature of correlates of schizotypy dimensions. This study explored the clustering of positive and negative schizotypy dimensions in nonclinical subjec...

Schizotypy is regarded as a trait vulnerability for psychotic disorders, yet alone is insufficient for development of a diagnosable disorder. Additional symptoms and psychological distress are necessary for help seeking and transition from an at risk mental state to a clinical diagnosis. The present study investigated the interaction between trait schizotypy, state auditory verbal hallucination...

OBJECTIVES Schizotypy relates to rejection sensitivity (anxiety reflecting an expectancy of social exclusion) and neuroticism (excessive evaluation of negative emotions). Positive schizotypy (e.g., perceptual aberrations and odd beliefs) and negative schizotypy (e.g., social and physical anhedonia) could relate to altered attention to rejection because of neuroticism. METHODS Forty-one health...

Cannabis acutely increases schizotypy and chronic use is associated with elevated rates of psychosis. Creative individuals have higher levels of schizotypy, however links between cannabis use, schizotypy and creativity have not been investigated. We investigated the effects of cannabis smoked naturalistically on schizotypy and divergent thinking, a measure of creativity. One hundred and sixty c...

Abstract. The vulnerability for schizophrenia-spectrum disorders is expressed across a continuum of clinical and subclinical symptoms impairment known as schizotypy. Schizotypy multidimensional construct with positive, negative, disorganized dimensions. Openness to experience offers useful personality domain exploring This study examined the factor structure openness its relation schizotypy usi...

People high in schizotypy, a risk factor for schizophrenia-spectrum disorders, can have negative symptoms, including diminished experience of motivation/pleasure (MAP) and emotional expressivity (EXP). Additionally, people high in schizotypy often report elevated depressive symptoms, which are also associated with diminished MAP and EXP. In this study, we examined whether negative symptoms were...

Positive and negative schizotypy exhibit differential patterns of impairment in social relations, affect, and functioning in daily life. However, studies have not examined the association of schizotypy with real-world expression of psychotic-like, paranoid, and negative symptoms. The present study employed experience-sampling methodology (ESM) to assess positive and negative schizotypy in daily...

BACKGROUND SPEM dysfunction is a well-known phenomenon in schizophrenia. The principal aim of the present study was to examine whether SPEM dysfunction is already observable in subjects scoring high on a specific measure of schizotypy (SSQ General Schizotypy) that was selected because of its intimate relationship with schizophrenic prodromal unfolding. METHODS Applying ANOVAs, we determined t...

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...
