  ASSESSMENT OF ESSENTIAL COMPONENTS OF SCHIZOTYPY USING NEUROCOGNITIVE MEASURES Serafín Lemos Giráldez, Mercedes Inda ...
Schizotypy is not a unitary set of traits, but consists rather of several reliably identifiable components, not all of which are equally important in predicting risk of disorders from the spectrum of schizophrenia.
The aim of this study was to verify that the negative factor of schizotypy is the most important and useful element in the prediction of risk, as it is consistently and differentially related to several frontal cognitive deficits, by comparison with other elements.
Subsequently, the definition of schizotypy was reformulated on the basis of two different lines of research, one based on the observation of some behavioural characteristics of the relatives of schizophrenic patients and another based on the transitory and subclinical psychotic experiences observed in people with no family history of schizophrenia (Kendler, 1985).

  Schizotypy - Psychology Wiki
Schizotypy is a psychological concept which describes a continuum of personality characteristics and experiences related to psychosis and in particular, schizophrenia.
Each approach is sometimes used to imply that schizotypy reflects a cognitive or biological vulnerability to psychosis, although this may remain dormant and never express itself, unless triggered by appropriate environmental events or conditions (such as certain doses of drugs or high levels of stress).
Further evidence that there is a non-linear relationship between schizotypy and some cognitive factors known to be affected in schizophrenia (such as latent inhibition) is also given as evidence for the quasi-dimensional approach.

Schizotypy is a psychological concept which describes a continuum of personality characteristics and experiences related to psychosis.
Claridge named his concept schizotypy and by examining unusual experiences in the general population and the clustering of symptom s in diagnosed schizophrenia, Claridge's work suggested that this personality trait was much more complex, and could break down into four factors.
Although aiming to reflect some of the features present in diagnosable mental illness, schizotypy does not imply that someone who is more schizotypal than someone else is necessarily more ill. Certain aspects of schizotypy may be beneficial.

The analyses revealed that decreased verbal fluency was associated with increased levels of negative schizotypy in participants who scored one standard deviation above the mean on the ‘Introvertive Anhedonia’ scale.
In contrast, increased verbal fluency was associated with increased levels of positive schizotypy in participants who scored one standard deviation above the mean on the ‘Unusual Experiences’ scale.

 Sara's Honours Thesis
Schizotypy is a continuous construct measurable in the normal population.
Schizotypy correlated with both creativity measures, with r =.302, p =.009 for Per-Mag with Remote Associates Test, and r =.218, p =.047 for Per-Mag with Written Fluency, indicating co-occurrence of creative and schizotypal thought.
Schizotypy is a multidimensional construct, and Social Anhedonia is considered to be opposite in nature to the Per-Mag construct (labelled as negative and positive facets, respectively).

To determine if high schizotypy individuals prefer social activities high in situational demand (e.g., going to a movie with friends) than less structured situations (e.g., socializing at a bar), 52 high schizotypy and 60 low schizotypy individuals reported their enjoyment and frequency of engaging in social situations varying in structure.
Schizotypy was associated with greater reported annoyance across mood assessment intervals, accounting for 11% of the variance, and with feeling less close to the interviewer, 18% of variance.
Total schizotypy scores were not predictive of changes in mood in response to the emotional content of the interview, however, greater levels of referential thinking were associated with sustained annoyance despite reparative efforts of the interviewer, r =.29.

 Depression and anxiety linked to positive schizotypy symptoms   (Site not responding. Last check: )
Study findings indicate that, in patients with schizotypy, symptoms of depression and anxiety are more strongly associated with positive than negative symptoms, as has previously been shown in patients with schizophrenia.
For their study, the team examined the relationship of psychometrically defined schizotypy with symptoms of depression and anxiety in a college student sample of 1258 individuals.
The researchers add that, although positive symptoms are correlated with a better prognosis for patients with schizophrenia, the presence of depression and anxiety in premorbid or prodromal schizotypy appears to increase the risk of transition to psychosis.

The dimensional approach, influenced by personality theory, argues that full blown psychotic illness is just the most extreme end of the schizotypy spectrum and there is a natural continuum between people with low and high levels of schizotypy.
Similarly, when analysed, schizotypy traits often break down into similar groups as do symptoms from schizophrenia (although they are typically present in much less intense forms).

We also investigated the relationship between positive/negative schizotypy and associated clinical states or personality dimensions including antisocial personality disorder, obsessive-compulsive personality traits, generalized and social anxiety, empathy, and impulsivity.
Negative schizotypy was associated with subtle performance deficits on measures of frontal executive function, increased social anxiety, and obsessive-compulsive phenomena.

Schizotypal symptoms appear to be associated with mixed, or ambiguous, handedness even in Japanese individuals, who, due to cultural pressures, are encouraged to adopt right-handedness, say researchers.
These findings expand on research, previously carried out in Europe and North America, indicating that atypical cerebral lateralization, one measure of which is handedness, is a risk factor for schizophrenia.
These findings are consistent with the concept that "failure of lateralization is a risk factor for certain pathology," in this case schizotypy and subsequent schizophrenia, the team concludes.

The structure of schizotypy: relationships between neurocognitive and personality disorder features in relatives of schizophrenic patients in the UCLA Family Study.
Schizotypal personality features and certain neurocognitive deficits have been shown to aggregate in the relatives of schizophrenic patients, supporting the view that both are likely to reflect genetic contributions to liability to schizophrenia.
These analyses support the view that schizotypy is multidimensional in relatives of schizophrenic patients and indicate that neurocognitive deficits in perception and attention are associated with particular schizotypal personality features.
