The Moderating Effects Of Perceived Intentionality: Exploring The Relationships Between Ideas Of Reference, Paranoia, And Social Anxiety In Schizotypy, Sean Cameron Morrison

LSU Master's Theses

Ideas of reference (IOR), paranoia, and social anxiety are three common symptoms of schizophrenia-spectrum disorders, which appear to be conceptually related. However, the precise nature of these relationships is unclear. A new measure that assesses perceived intentionality (PI), a social-cognitive bias for perceiving the actions of others during unpleasant social situations as being directed at oneself in an intentionally malicious manner, has provided preliminary evidence for a link between PI and paranoia. The primary aim of this study was to examine the moderating role of PI on the relationships between IOR and paranoia, and between IOR and social anxiety amongst …

Individuals with schizophrenia tend to demonstrate patterns of atypical semantic activation, which are characterized by increased activation of weakly associated words within the semantic network. Although atypical semantic activation is associated with formal thought disorder, tangential speech, and poor long-term functioning in schizophrenia, very little is known about this variable in individuals with schizotypy, or the 10% of the population who demonstrate personality traits presumed to reflect genetic liability to schizophrenia. In this project, we employed highly sensitive laboratory procedures to test whether individuals with schizotypy (n = 45) display increased atypical semantic activation compared to a non-schizotypy group (n …
