The spiritual but not religious (SBNR) are a growing population in secularizing societies. Yet, we know little about the underlying psychology of this group or their belief profile. Based on an individual difference approach, we address this knowledge gap by comparing SBNR with religious and non-religious participants. In a sample of Americans (n=1013), we find that the SBNR differ from non-religious and religious participants in a number of ways. SBNR participants are more likely to hold paranormal beliefs and to have an experiential relationship to the supernatural (e...

There is a high prevalence of psychotic-like experiences in nonclinical patient cohorts from Brazil. This study aimed to test whether personality dimensions, as well as schizotypy, are important predictors of quality of life (QoL) in individuals with psychotic experiences (PE). METHOD: 115 participants were recruited from Spiritist Centers in Brazil. At the 1-year follow up, 90 participants (78%) were reassessed. Instruments were the SCID-I (Structured Clinical Interview for DSM-IV), TCI-R 140 (Revised Temperament and Character Inventory), OLIFE-R (Oxford-Liverpool Inventory of Feelings and Experiences), and WHOQOL-BREF (World Health Organization QoL Instrument)...

OBJECTIVE: While diagnostically independent, autism and schizotypal disorders can co-occur. Their concurrent impact on outcomes and phenotypes has not been investigated. We investigated the impact of comorbid autism and schizotypal disorders in children on executive functioning and socio-pragmatic skills - core features of both disorders. METHOD: Executive functioning (assessed with the Cambridge Neuropsychological Test Automated Battery) and socio-pragmatic skills (assessed using the Melbourne Assessment of Schizotypy in Kids) were investigated in a total of 67 (6-12 year old) children with autism ( n = 15; M/F = 10/5), schizotypal disorder ( n = 8; M/F = 5/3) and comorbid autism and schizotypal disorder ( n = 12; M/F = 5/7) and typically developing children ( n = 32; M/F = 17/15)...

A recent study (Lemaitre et al., 2016, Consciousness and Cognition, 41, 64-71) found that non-clinical individuals who scored highly on a psychometric scale of schizotypy were able to tickle themselves. The present study aimed to extend this finding by investigating whether the ability to tickle oneself was associated with level of psychometric schizotypy considered as a continuous variable. One hundred and eleven students completed the Schizotypal Personality Questionnaire (SPQ). A mechanical device delivered tactile stimulation to participants' palms...

BACKGROUND: Cognitive failures are disruptions in cognitive functioning during everyday life. Vulnerability to these failures is increased in a range of psychological disorders, including schizophrenia. In addition, healthy individuals with personality-based psychosis proneness, or schizotypy, often complain of heightened failures. A factor known to exacerbate cognitive failures is negative affect. Negative affectivity is linked to both schizophrenia and schizotypy. It is therefore possible that affect is responsible for the increased everyday cognitive failures in "high schizotypes"...

The ability to inhibit inappropriate responses and suppress irrelevant information is a core feature of executive control. In this study, we provide a detailed analysis of prepotent response inhibition and interference in patients with schizophrenia. To further test the role of genetic factors and subclinical schizophrenia-like traits, we additionally studied clinically unaffected, first-degree relatives of schizophrenia patients and assessed dimensions of schizotypy in both relatives and healthy controls. Inhibition and interference control were assessed using a battery comprising the antisaccade, Stroop, stop signal, go/no-go, flanker, and Simon tasks...

BACKGROUND: The liability-threshold model of psychosis risk predicts stronger phenotypic manifestation of the polygenic risk score (PRS) in the healthy relatives of patients, as compared with healthy comparison subjects. METHODS: First-degree relatives of patients with psychotic disorder (871 siblings and 812 parents) and healthy comparison subjects (n = 523) were interviewed three times in 6 years. Repeated measures of two psychosis phenotypes, the Community Assessment of Psychic Experiences (CAPE; self-report - subscales of positive, negative and depressive symptoms) and the Structured Interview for Schizotypy - Revised (SIS-R; clinical interview - subscales of positive and negative schizotypy), were examined for association with PRS...

Evidence suggests that attachment styles may influence subclinical psychosis phenotypes (schizotypy) and affective disorders and may play a part in the association between psychosis and childhood adversity. However, the role of attachment in the initial stages of psychosis remains poorly understood. Our main aim was to describe and compare attachment styles in 60 individuals at ultra high risk for psychosis (UHR) and a matched sample of 60 healthy volunteers (HV). The HV had lower anxious and avoidant attachment scores than the UHR individuals (p < ...

Nowadays, both in the clinical population, and in general communities, we tend to encounter an increasing number of personality disorder patients, whose social adjustment, partnerships and efficient life management is made difficult by the disorder. The ideas of borderline personality disorder patients, who fluctuate between farfetched expectations and fears of their selves being demolished, schizoid patients, who close their selves in their own alienating prison, avoidant patients, who try to escape difficulties, which would enhance their self-esteem, OCD patients, who build their own mythic superstitious world, and antisocial patients who tend to ignore and aggressively override others' interests are all important in the development of cultures with insecure identities...

Objective: The aim of the study was to compare the neurocognitive profile of unaffected first-degree relatives of schizophrenia patients with control individuals, controlling for different schizotypal traits. Method: One hundred and fifteen adult unaffected first-degree relatives of schizophrenia-spectrum patients and 122 controls were tested for schizotypy with the Schizotypal Personality Questionnaire. They also underwent a thorough neurocognitive assessment with a range of tasks covering several aspects of executive functioning...

Animal models and human neuroimaging studies suggest that altered levels of glutamatergic metabolites within a corticolimbic circuit have a major role in the pathophysiology of schizophrenia. Rodent models propose that prefrontal glutamate dysfunction could lead to amygdala hyper-response to environmental stress and underlie hippocampal overdrive in schizophrenia. Here we determine whether changes in brain glutamate are present in individuals with high schizotypy (HS), which refers to the presence of schizophrenia-like characteristics in healthy individuals, and whether glutamate levels are related to altered corticolimbic response to emotion...

BACKGROUND: The experience of 'sensed presence'-a feeling or sense that another entity, individual or being is present despite no clear sensory or perceptual evidence-is known to occur in the general population, appears more frequently in religious or spiritual contexts, and seems to be prominent in certain psychiatric or neurological conditions and may reflect specific functions of social cognition or body-image representation systems in the brain. Previous research has relied on ad-hoc measures of the experience and no specific psychometric scale to measure the experience exists to date...

The main goal of the present study was to explore the latent structure of schizotypal traits in non-clinical young adults, and compare the latent profiles in clinical and personality characteristics: mental distress, psychosis-proneness, hypomanic experiences, and anticipatory and consummatory pleasure. A large sample of college students (N =1002; mean age =21.11 years; SD =3.92) were administered the Schizotypal Personality Questionnaire-Brief Revised, the Mood Disorder Questionnaire, the short version of the Oxford-Liverpool Inventory of Feelings and Experiences, the General Health Questionnaire-12, and the Temporal Experience of Pleasure Scale...

Schizotypal personality disorder (SPD) is characterised by thought disorders, experiences of illusions, obsessive ruminations, bizarre or eccentric behaviour, cognitive problems and deficits in social functioning - symptoms that SPD shares with schizophrenia. Efforts have been undertaken to investigate the relationship between these conditions regarding genetics, pathophysiology, and phenomenology. However, treatment of SPD with antipsychotics has received less scientific attention. Embase and PubMed databases were searched using all known generic names of antipsychotics as search terms in combination with the following diagnostic terms: latent schizophrenia, schizotypal disorder, latent type schizophrenia, or SPD...

INTRODUCTION: Cognitive deficits can precede the onset of psychotic episodes and predict the onset of the illness in individuals with schizotypy traits. In some studies, high levels of schizotypy were associated with impairments in memory, attention, executive functions, and verbal fluency. This review provides a more comprehensive understanding of cognitive impairments related to schizoytpy. METHODS:  A systematic review of "schizotypy and neuropsychological measures" was conducted, and it retrieved 67 studies...

INTRODUCTION: Although social cognition skills and biases are well-studied in paranoia, "mind perception" - perceiving the extent to which someone even possesses a thinking, feeling mind - is not. We sought to better characterise the profile of mind perception for individuals with paranoia. METHODS: We examined links between mind perception and paranoia in a large (n = 890) subclinical sample. Participants completed measures of paranoia, schizotypy, mind perception, and dispositional empathy...

BACKGROUND: DSM-5 proposes an Attenuated Psychosis Syndrome (APS) for further investigation, based upon the Attenuated Positive Symptom Syndrome (APSS) in the Structured Interview for Psychosis-Risk Syndromes (SIPS). SIPS Unusual Thought Content, Disorganized Communication and Total Disorganization scores predicted progression to psychosis in a 2015 NAPLS-2 Consortium report. We sought to independently replicate this in a large single-site high-risk cohort, and identify baseline demographic and clinical predictors beyond current APS/APSS criteria...

OBJECTIVES: The aim of the study was to assess schizotypy by using the Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE), in the groups of patients with schizophrenia, bipolar disorder (BD) and unipolar (recurrent) depression (UD). An important element of the study was to compare - in terms of similarity - the results obtained in schizophrenia and BD, and - in terms of differences - the results obtained in BD and UD. METHODS: The study involved 58 patients with schizophrenia (35 men, 23 women, mean age = 34...

BACKGROUND: Maternal depression is relatively common during pregnancy. However, follow-ups of the adult offspring of antenatally depressed mothers are scarce. Previously we found the risk of schizophrenia to be higher in the adult offspring with antenatally depressed mothers and parents with psychosis than in subjects with only one or neither of these risk factors. The aim was to study whether the risk of schizotypal or affective traits differ among adult offspring with antenatally depressed mothers with or without a parental history of psychosis when compared with offspring without antenatally depressed mothers and without parental psychosis...

One of teenagers' key developmental tasks is to engage in new and meaningful relationships with peers and adults outside the family context. Attachment-derived expectations about the self and others in terms of internal attachment working models have the potential to shape such social reorientation processes critically and thereby influence adolescents' social-emotional development and social integration. Because the neural underpinnings of this developmental task remain largely unknown, we sought to investigate them by functional magnetic resonance imaging...
