Testing the continuum of delusional beliefs: an experimental study using virtual reality.

ABSTRACT: A key problem in studying a hypothesized spectrum of severity of delusional ideation is determining that ideas are unfounded. The first objective was to use virtual reality to validate groups of individuals with low, moderate, and high levels of unfounded persecutory ideation. The second objective was to investigate, drawing upon a cognitive model of persecutory delusions, whether clinical and nonclinical paranoia are associated with similar causal factors. Three groups (low paranoia, high nonclinical paranoia, persecutory delusions) of 30 participants were recruited. Levels of paranoia were tested using virtual reality. The groups were compared on assessments of anxiety, worry, interpersonal sensitivity, depression, anomalous perceptual experiences, reasoning, and history of traumatic events. Virtual reality was found to cause no side effects. Persecutory ideation in virtual reality significantly differed across the groups. For the clear majority of the theoretical factors there were dose-response relationships with levels of paranoia. This is consistent with the idea of a spectrum of paranoia in the general population. Persecutory ideation is clearly present outside of clinical groups and there is consistency across the paranoia spectrum in associations with important theoretical variables.

Project description:BackgroundClinical practice in neonatal intensive care units for nursing college students has been restricted due to the COVID-19 pandemic outbreak; thus, the gamification program has emerged as an alternative learning method. Consequently, there is a need to examine the effectiveness of such alternative learning methods to enhance the response to high-risk newborn emergencies.ObjectivesTo examine the effects (neonatal resuscitation nursing knowledge, problem-solving and clinical reasoning ability, self-confidence in practical performance, degree of anxiety, and learning motivation) of a neonatal resuscitation gamification program using immersive virtual reality based on Keller's ARCS model.DesignA non-randomized controlled simulation study with a pretest-posttest design.SettingLab and lecture rooms of two universities in South Korea, from June to November 2021.ParticipantsPrelicensure nursing students.MethodsThe virtual reality group (n = 29) underwent a neonatal resuscitation gamification program using virtual reality based on Keller's ARCS model. The simulation group (n = 28) received high-fidelity neonatal resuscitation simulations and online neonatal resuscitation program lectures. The control group (n = 26) only received online neonatal resuscitation program lectures. Changes in scores among these groups were compared using analysis of variance and analysis of covariance with SPSS for Windows version 27.0.ResultsPost intervention, neonatal resuscitation knowledge [F(2) = 3.83, p = .004] and learning motivation [F(2) = 1.79, p = .025] were significantly higher in the virtual reality and simulation groups than in the control group, whereas problem-solving ability [F(2) = 2.07, p = .038] and self-confidence [F(2) = 6.53, p < .001] were significantly higher in the virtual reality group than in the simulation and control groups. Anxiety [F(2) = 16.14, p < .001] was significantly lower in the simulation group than in the virtual reality and control groups.ConclusionsThe neonatal resuscitation gamification program using immersive virtual reality was found to be effective in increasing neonatal resuscitation knowledge, problem-solving ability, self-confidence, and learning motivation of the nursing students who participated in the trial application process.

Project description:Objectives: Attention Restoration Theory (ART) suggests that walking or being in natural settings, as opposed to urban environments, benefits cognitive skills because it is less demanding on attentional resources. However, it is unclear whether the same occurs when the person is performing a complex task such as driving, although it is proven that driving through different road environments is associated with different levels of fatigue and may engage attention differently. The present study investigated whether exposure to rural vs. urban road environments while driving would affect attentional capacity in young people after the drive, in line with the classic ART paradigms. Methods: We asked 38 young participants to complete the Sustained Attention to Response Task (SART) before and after being exposed to a rural or urban road in a virtual reality environment while driving in a full vehicle immersive driving simulator. Changes in SART performance based on environmental exposure where explored in terms of target sensitivity, accuracy, reaction times, and inverse efficiency. We analyzed potential road type effects on driving speed and accuracy. Possible effects of driving on attention were tested by comparing the sample performance to that of a control group of 15 participants who did not drive and sat on the passenger seat instead. Results: Exposure to rural or urban road environments in the driving sample was not associated with any significant changes in attentional performance. The two exposure groups did not differ significantly in terms of driving behavior. Comparisons between the driving sample and the control group controlling for age indicated that participants who drove were more accurate but slower at the SART than those who were passengers. Conclusion: The present study does not support the hypothesis that a short drive in a natural setting may promote attention restoration as compared to an urban setting. Methodological considerations as well as recommendations for future research are discussed.
