Within this investigation, the self-disorder hypothesis of schizophrenia was assessed via an illusory perceptual paradigm. It has been proposed that alteration of basic (minimal) selfhood may underlie cognitive and perceptual disturbances in psychosis (Sass, 2014). Disturbed corporeality (i.e., anomalous experience of one’s body) is an identified component of basic self-disturbance. As it is difficult to empirically capture the spontaneous occurrence of anomalous bodily experiences as they arise, the Pinocchio Illusion (PI) has been employed to capture variations in the plasticity of bodily self-experience (specifically, body boundary plasticity) (Michael & Park, 2016). The PI paradigm provides for the sensations of arm …
The Impact Of Cannabis Use On Neuropsychological And Neural Biomarkers Of Treatment Response In Schizophrenia Spectrum Disorders, Melanie B. Thies
The Impact Of Cannabis Use On Neuropsychological And Neural Biomarkers Of Treatment Response In Schizophrenia Spectrum Disorders, Melanie B. Thies
Dissertations, Theses, and Capstone Projects
Cannabis use among patients with schizophrenia-spectrum disorders (SSD) is at significantly greater levels than in healthy populations but the impact of cannabis on neural mechanisms of clinical improvement is poorly understood. Cognitive functioning and neural connectivity are disrupted as a result of both SSD and cannabis use, and research indicates that neuropsychological capacity and connectivity of the striatum, a region involved in salience and reward processing, may be integral to effective antipsychotic drug (AP) treatment response. Despite this overlap, no previous research has investigated the effect of cannabis on the brain functions implicated in AP treatment response. The present study …

Malingering includes the intentional feigning of psychiatric symptoms combined with motivation for external gain (American Psychiatric Association, 2013). Malingering is likely to occur in the justice system in both criminal and civil contexts, as there is increased opportunity for secondary gain in these settings. When individuals successfully malinger, it can be very costly for the United States. For example, if an individual successfully malingers, it can delay their criminal proceedings, allow them to inappropriately use resources associated with psychiatric or medical treatment, allow them to gain access to unneeded medications or financial assistance, or allow them to avoid work (Chafetz …
The Prediction Of Personal Narrative On Features Of Recovery Among People With Schizophrenia-Spectrum Disorders, Beth Vayshenker
The Prediction Of Personal Narrative On Features Of Recovery Among People With Schizophrenia-Spectrum Disorders, Beth Vayshenker
Dissertations, Theses, and Capstone Projects
Among individuals with schizophrenia, research has demonstrated that in addition to the positive and negative symptoms characteristic of schizophrenia, the diminishment of the self also represents an important aspect of the illness (Lysaker & Lysaker, 2010). Research has confirmed that the self-experience, particularly as measured by the telling of one’s life story through the Scale to Assess Narrative Development (STAND), is linked to a variety of subjective and objective recovery outcomes from schizophrenia. While this association has been documented in different research studies, less is known about the ways in which personal narrative functions to predict recovery outcomes in a …
Neurologists Look At Causes Of Baffling Brain Condition, Maggie Freleng
Neurologists Look At Causes Of Baffling Brain Condition, Maggie Freleng
Capstones
It can be hard getting help for someone with mental illness, but almost impossible when that person doesn't think they are sick. At at least half of people with schizophrenia, for example, insist that the voices they hear are real. People who do not know they are ill often refuse therapy and medication -- and their symptoms can spiral out of control. Doctors call this lack of awareness anosognosia. Neurologists are trying to discover what causes this baffling condition--and how to treat it.
