Schizotypy and latent inhibition: non-linear linkage between psychometric and cognitive markers
نویسندگان
چکیده
Auditory latent inhibition (LI) and schizotypy were measured in (n=54), showing that LI was an inverted-U function of schizotypy score. Only average levels of schizotypy were associated with undiminished LI while both lowand high-SPQ subjects showed reduced LI. No relationship was found between LI and either psychoticism or any of the ®ve NEO PI-R domains. These results complement the similar complex relationship of neuroleptic drug dose eects on LI in normals and schizophrenics. A priming task and the unusual uses and pattern meanings measures of creativity were related to personality measures of schizotypy, N, E, and O (but not the EPQ-R psychoticism, LI, or priming performance). Priming eects tracked the inverted-U function of schizotypal personality questionnaire (SPQ) scale scores shown in the LI task. It is suggested that LI is dependent on a non-linear interaction with masking task load and attentional allocation, modulated by schizotypy. # 2001 Elsevier Science Ltd. All rights reserved.

Category fluency in psychometric schizotypy: how altering emotional valence and cognitive load affects performance.
INTRODUCTION In clinical high-risk populations, category fluency deficits are associated with conversion to psychosis. However, their utility as clinical risk markers is unclear in psychometric schizotypy, a group experiencing schizophrenia-like traits that is at putative high risk for psychosis. METHODS We examined whether introducing affective or cognitive load, two important stress vulnera...
متن کاملThe Psychometric Detection of Schizotypy : Do Putative Schizotypy Indicators Identify the Same Latent Class? By:
The authors examined whether three indicators of Schizotypy, the Revised Social Anhedonia Scale (RSAS), Magical Ideation Scale (MIS), and Perceptual Aberration Scale (PAS), identify a common latent class or taxon as conceptualized by P. E. Meehl (1962, 1990). The separate and joint latent structures of these scales were evaluated using taxometric methods in two large, independent samples. Repli...
متن کاملWhich schizotypal dimensions abolish latent inhibition?
OBJECTIVE To evaluate which dimensions of schizotypy are associated with a reduction in latent inhibition (LI), akin to that seen in schizophrenia. DESIGN LI was compared in low and high scorers on the four dimensions of the OLIFE questionnaire (Mason, Claridge, & Jackson, 1995), with the predictions that the unusual experiences and impulsive non-conformity subscales would be associated with ...
متن کاملAssessing the Construct Validity of Aberrant Salience
We sought to validate the psychometric properties of a recently developed paradigm that aims to measure salience attribution processes proposed to contribute to positive psychotic symptoms, the Salience Attribution Test (SAT). The "aberrant salience" measure from the SAT showed good face validity in previous results, with elevated scores both in high-schizotypy individuals, and in patients with...
متن کاملResolving the latent structure of schizophrenia endophenotypes using expectation-maximization-based finite mixture modeling.
Prior research has focused on the latent structure of endophenotypic markers of schizophrenia liability, or schizotypy. The work supports the existence of 2 relatively distinct latent classes and derives largely from the taxometric analysis of psychometric values. The present study used finite mixture modeling as a technique for discerning latent structure and the laboratory-measured endophenot...
