Autobiographical Memory And Theory Of Mind In Schizotypy, Andrew Deptula
Autobiographical Memory And Theory Of Mind In Schizotypy, Andrew Deptula
Electronic Theses and Dissertations
Individuals with schizophrenia exhibit marked impairments on tasks assessing theory of mind (ToM) and autobiographical memory (AM) qualities, and preliminary research has indicated a positive link between these abilities. This study is the first to systematically explore this relationship in the related personality trait of schizotypy. In a study of 47 undergraduate students (23 males) reporting a wide continuous range of schizotypy, we found that females, but not males, exhibited a negative correlation between ToM and schizotypy, and an unexpected positive correlation between AM qualities and schizotypy. Factor score analysis within females indicated that disorganized schizotypy was the strongest correlate …
Measurement Of Negative Affectivity In Psychometrically Defined Schizotypy Using Facial Electromyography, Jonathan Mitchell
Measurement Of Negative Affectivity In Psychometrically Defined Schizotypy Using Facial Electromyography, Jonathan Mitchell
Electronic Theses and Dissertations
Schizotypy is a sub-threshold syndrome associated with schizophrenia. Much of the research on schizotypy concerns its component features, one of which being blunted or constricted affect. While several investigations have addressed this common “negative” symptom within the context of schizophrenia, few have focused on schizotypy directly, and none have utilized psychophysiological measurement to examine affective constriction. The present investigation uses facial electromyography (EMG) to measure patterns of affective expression within a psychometrically defined schizotypal population when presented threatening and distressing pictures from the IAPS. Twenty-eight individuals with elevated schizotypal features and 20 healthy controls were recruited for this investigation. The …
Comorbidity Of Psychopathy In Schizotypy: Skin Conductance To Affective Pictures, Kathleen A. Ragsdale
Comorbidity Of Psychopathy In Schizotypy: Skin Conductance To Affective Pictures, Kathleen A. Ragsdale
Electronic Theses and Dissertations
Prior research substantiates a relationship between psychopathy and schizophrenia-spectrum disorders, which has begun to elucidate why some individuals with schizophrenia are violent. Unfortunately, this relationship has been limited to self-report. To objectively corroborate this finding, undergraduate students were recruited from an online screening administration of the Schizotypal Personality Questionnaire. This resulted in 56 participants (52% male) with a mean age of 20.37 (SD = 4.74) and a wide range of schizotypy scores who participated in the experiment. Following completion of self-report measures, participants viewed 15 pictures (five neutral, five threatening, and five of others in distress) from the International Affective …
