Freeman et al. reported that a substantial minority of the general population has paranoid thoughts while exposed in a virtual environment. This suggested that in a development phase of a virtual reality exposure system for paranoid patients initially a non-clinical sample could be used to evaluate the system's ability to induce paranoid thoughts. To(More)
Initial studies with healthy subjects and individuals with high risk for psychosis have suggested that virtual reality (VR) environments may be used to investigate social and psychological mechanisms of psychosis. One small study reported that VR can safely be used in individuals with current persecutory delusions. The present pilot study investigated the(More)
(2011). Using virtual reality to study paranoia in individuals with and without psychosis. Abstract. A virtual reality environment was created to study psychotic symptoms of patients that experience psychosis. In the environment people could navigate through a bar with a gamepad while wearing a head mounted display. Their task was to find five virtual(More)
A Virtual Reality (VR) environment was created to study psychotic symptoms in patients and non-patients. Participants' task was to find five virtual characters that each had a small number label on his or her chest. The density and ethnic appearance of the virtual characters in the bar was controlled. For a non-patient group (N=24), results showed a(More)
OBJECTIVE To enable further understanding of how cognitive deficits and psychopathology impact psychosocial functioning in first-episode psychosis patients, we investigated how psychopathology and cognitive deficits are associated with psychosocial problems at baseline, and how these predict psychosocial functioning at 12 months follow-up. Also, we tested(More)
BACKGROUND While ethnic diversity is increasing in many Western countries, access to youth mental health care is generally lower among ethnic minority youth compared to majority youth. It is unlikely that this is explained by a lower prevalence of psychiatric disorders in minority children. Effective screening methods to detect psychiatric disorders in(More)
In recent years, virtual reality (VR) research on psychotic disorders has been initiated. Several studies showed that VR can elicit paranoid thoughts about virtual characters (avatars), both in patients with psychotic disorders and healthy individuals. Real life symptoms and VR experiences were correlated, lending further support to its validity.(More)
Although virtual reality exposure has been reported as a method to induce paranoid thought, little is known about mechanisms to control specific virtual stressors. This paper reports on a study that examines the effect of controlling the stream of potential paranoia evoking events in a virtual restaurant world. A 2-by-2 experiment with a non-clinical group(More)
