Over the past years, research has shown that virtual reality (VR) technology can be used to observe, interpret, and change human behavior and cognition in a variety of domains. This chapter explores the potential of VR as a tool to observe, interpret, and change human behavior and cognition as they relate to antisocial behavior. We review the criminological research literature as well as research literature from related disciplines on VR applications that has focused on observing and reducing antisocial behavior. The main findings of our review suggest that the key merits of VR in the domain of crime and antisocial behavior are its ability to provide safe learning environments that would otherwise involve risk, the possibility of generating ethical and ecologically valid virtual alternatives for real-life situations, and the development of stimuli that are impossible to create in real life. These unique characteristics make VR a promising tool to observe criminal behavior as it takes place and develop intervention programs to reduce antisocial behavior., (Copyright © 2023 Elsevier B.V.

Background: Short-term mindsets are associated with self-defeating behaviors, such as delinquency and alcohol use. In contrast, people who consider the longer-term consequences of their decisions tend to report positive outcomes, like feeling more competent and enhanced goal achievement. We evaluate an intervention, FutureU, that aims to stimulate future-oriented thinking, increase goal achievement, and reduce self-defeating behavior, by strengthening people's identification with their future self. The intervention will be delivered through a smartphone application (app) or immersive Virtual Reality (VR). We test the effectiveness of FutureU for both delivery methods, examine working mechanisms, and identify potential moderators of intervention effects., Methods: In this Randomized Controlled Trial, a total of 240 first-year university students (n = 80 per condition) will be randomized into one of three conditions: (1) a smartphone condition, (2) a VR condition, and (3) an active control condition. We will assess proximal (i.e., future self-identification) and distal intervention outcomes (e.g., future orientation, self-defeating behaviors, goal achievement), user engagement, and examine usage data and goal content. Assessments will take place at baseline, during the intervention, immediately after the intervention, and at 3- and 6-months follow-up., Discussion: This study will provide information on the effectiveness of the intervention and allows for comparisons between delivery methods using novel technologies, a smartphone app versus immersive VR. Knowledge gained through this study can be used for further intervention development as well as theory building. Trial registration This trial is registered on Clinicaltrials.gov (NCT05578755) on 13 October 2022., (© 2022. The Author(s).)

Importance: Globally, access to evidence-based psychological treatment is limited. Innovative self-help methods using smartphone applications and low-cost virtual reality have the potential to significantly improve the accessibility and scalability of psychological treatments., Objective: To examine the effectiveness of ZeroPhobia, a fully self-guided app-based virtual reality cognitive behavior therapy (VR CBT) using low-cost (cardboard) virtual reality goggles compared with a wait-list control group and to determine its user friendliness., Design, Setting, and Participants: In a single-blind randomized clinical trial, participants were enrolled between March 24 and September 28, 2017, and randomly assigned (1:1) by an independent researcher to either VR CBT app or a wait-list control group. A total of 193 individuals aged 18 to 65 years from the Dutch general population with acrophobia symptoms and access to an Android smartphone participated. The 6 animated modules of the VR-CBT app and gamified virtual reality environments were delivered over a 3-week period in participants' natural environment. Assessments were completed at baseline, immediately after treatment, and at 3-month follow-up. Analysis began April 6, 2018, and was intention to treat., Intervention: Self-guided app-based VR CBT., Main Outcomes and Measures: The primary outcome measure was the Acrophobia Questionnaire. The hypothesis was formulated prior to data collection., Results: In total, 193 participants (129 women [66.84%]; mean [SD] age, 41.33 [13.64] years) were randomly assigned to intervention (n = 96) or a wait-list control group (n = 97). An intent-to-treat analysis showed a significant reduction of acrophobia symptoms at posttest at 3 months for the VR-CBT app compared with the controls (b = -26.73 [95% CI, -32.12 to -21.34]; P < .001; d = 1.14 [95% CI, 0.84 to 1.44]). The number needed to treat was 1.7. Sensitivity and robustness analysis confirmed these findings. Pretreatment attrition was 22 of 96 (23%) because of smartphone incompatibility. Of the 74 participants who started using the VR-CBT app, 57 (77%) completed the intervention fully., Conclusions and Relevance: A low-cost fully self-guided app-based virtual reality cognitive behavioral therapy with rudimentary virtual reality goggles can produce large acrophobia symptom reductions. To our knowledge, this study is the first to show that virtual reality acrophobia treatment can be done at home without the intervention of a therapist., Trial Registration: Trialregister.nl identifier: NTR6442.

The intention-behavior gap is a common phenomenon where people fail to follow through on their intentions to change their behavior and pursue their future goals. Previous research has shown that people are more likely to act in favor of their future selves when they feel similar/connected to their future self and can vividly describe them. This study compared an imagination exercise with an integrated imagination and exposure exercise using virtual reality (VR) to embody age-morphed future selves to an imagination only exercise. We expected that strengthening the similarity/connectedness and the vividness of the future self would reduce the intention-behavior gap, and exposure to the future self would have the greatest effect. Surprisingly, the results showed that strengthening connectedness reduced the intention-behavior gap, but strengthening similarity increased the gap. Additionally, the exercises were equally effective in reducing the intention-behavior gap. These findings suggest that both feeling connected to and recognizing dissimilarity to one's future self play different roles in future-oriented behavior change. [ABSTRACT FROM AUTHOR]

This study examines the deterrent effects of neighbourhood watch signs and police signs as measures of symbolic guardianship on burglars versus non-offenders. In a virtual reality experiment, 181 burglars and 172 non-offenders scouted a virtual neighbourhood and were exposed to neighbourhood watch signs and/or signs suggesting police surveillance in the area. With neighbourhood watch signs present, both burglars and non-offenders perceived the neighbourhood residents as more likely to intervene. Burglars were also more likely to select a target closer to the exit than non-offenders when neighbourhood watch signs were present. The presence of police signs reduced the time spent scouting and the distance travelled for both burglars and non-offenders. Furthermore, as compared to non-offenders burglars selected houses with easier access, travelled less distance, and reported higher anticipation of neighbourhood resident intervention. Symbolic guardianship through neighbourhood watch or police sign seems to elicit only small effects in deterring burglars. They should not immediately be discounted as preventive measures, however, as small-effect interventions may be valuable as additions to well-established interventions. [ABSTRACT FROM AUTHOR]

In der Wissensgrundlage der kriminologischen Forschung bestehen gegenwärtig beachtliche Lücken: Es mangelt an wirklich interdisziplinärer Forschung; das Verständnis, wie Persönlichkeitseigenschaften mit kriminellem Verhalten zusammenhängen, ist begrenzt; dem Potenzial neuer Technologien, die helfen können, ein besseres Verständnis für die Prozesse zu bekommen, die während der Begehung von Straftaten ablaufen, wird zu wenig Beachtung geschenkt; und neue Erkenntnisse aus anderen Disziplinen, die das Verständnis von Straftaten sowie Kriminalität verbessern könnten, werden unzureichend angewendet. Die Abteilung Kriminologie am Max-Planck-Institut zur Erforschung von Kriminalität, Sicherheit und Recht hat es sich zum Ziel gesetzt, diese Lücken zu schließen. Durch theoretische Innovationen, die Nutzung neuer Technologien wie Virtual Reality und die Anwendung von kriminologischen Erkenntnissen in der Praxis soll der aktuell größtenteils soziologische und rechtliche Fokus des Faches erweitert und eine stärker verhaltensorientierte Perspektive eingebracht werden.

Virtual reality (VR) technology offers unique and as yet largely untapped potential for criminology. It can address problems that have traditionally plagued the field, provide an ecologically valid alternative for conventional research methods, and create novel possibilities for theory testing, and it allows for the study of phenomena that are difficult to research in the real world for ethical, safety, or practical reasons. This essay reviews the budding research literature using VR in criminogenic contexts, as well as relevant research from other disciplines, and explains the technology's basic features, current limitations, and ethical challenges. It concludes that within the foreseeable future, VR may become the criminological equivalent of the petri dish, offering the possibility to study the unfolding of highly complex behavioral processes in very detailed ways and help achieve step changes in our understanding of crime.

Trait‐state models aim to provide an encompassing view of offender decision‐making processes by linking individual dispositions to proximal factors. In an experiment using an immersive virtual reality bar fight scenario, we propose and test a trait‐state model that identifies the pathways through which robust personality correlates of aggressive behavior, that is, agreeableness, emotionality, and honesty‐humility, result in intentions to aggress. Using structural equation modeling, we show how these personality traits relate to intentions to aggress via anger, fear, perceived risk, and anticipated guilt/shame. Additionally, we demonstrate superior validity of our virtual scenario over a written version of the same scenario by virtue of its ability to provide more contextual realism, to establish a stronger sense of presence, and to trigger more intense emotional states relevant to the decision situation. Implications for future decision‐making research and theory are discussed. [ABSTRACT FROM AUTHOR]

In this study, we test an intervention in which convicted offenders interacted with an age-progressed avatar representing their future selves in virtual reality. During the interaction, they reflected on their current lifestyle, alternating between the perspective of their present self and that of their future self. We hypothesized that this embodied experience would increase their ability to imagine themselves in the future and reduce their engagement in self-defeating behavior, as measured with a self-report survey. In line with expectations, results indicated that the interaction increased vividness of the future self compared to baseline and reduced self-defeating behavior, including alcohol use and overspending, one week later. In addition, increases in vividness were associated with a reduction in self-defeating behavior over and above other concepts relating to the future self, including connectedness, similarity, and valence. The results are based on a small sample and should therefore be considered as indicative of the possibilities of our virtual reality paradigm as an intervention tool to reduce self-defeating behavior.

In the current study, we tested a novel perspective-taking exercise aimed at increasing the connection participants felt toward their future self, i.e., future self-continuity. Participants role-played as their successful future self and answered questions about what it feels like to become their future and the path to get there. The exercise was also conducted in a virtual reality environment and in vivo to investigate the possible added value of the virtual environment with respect to improved focus, perspective-taking, and effectiveness for participants with less imagination. Results show that the perspective taking exercise in virtual reality substantially increased all four domains of future self-continuity, i.e., connectedness, similarity, vividness, and liking, while the in vivo equivalent increased only liking and vividness. Although connectedness and similarity were directionally, but not significantly different between the virtual and in vivo environments, neither the focus, perspective taking, or individual differences in imagination could explain this difference—which suggests a small, but non-significant, placebo effect of the virtual reality environment. However, lower baseline vividness in the in vivo group may explain this difference and suggests preliminary evidence for the dependency of connectedness and similarity domains upon baseline vividness. These findings show that the perspective taking exercise in a VR environment can reliably increase the future self-continuity domains. [ABSTRACT FROM AUTHOR]

In recent years, virtual reality (VR) technology has convincingly demonstrated its potential for assessment, training, rehabilitation and treatment purposes in a variety of domains, including (mental) healthcare and education. This paper explores the possibilities for VR application within criminal justice practice. Criminological literature and literature of related disciplines on VR applications were reviewed with a special focus on risk assessment, correctional rehabilitation, and reintegration. We also devoted attention to the VR-based treatment of anxiety-related disorders among victims of crime. Literature shows that VR can provide safe learning environments that would otherwise involve risk, generate ethical and ecologically valid virtual alternatives for which real-life situations would be unethical to use, and develop environments that are impossible to create in the real life. These unique characteristics make VR a promising tool to expand the current toolbox of risk assessment instruments, and correctional rehabilitation and reintegration programs in important ways. Before implementing VR in criminal justice practice, an elementary understanding of both the advantages and disadvantages of VR technology is desirable but given a longstanding and effective VR tradition in other domains, the future of VR in criminal justice practice is bright.

Objectives: This study proposes an alternative hypothetical scenario method capitalizing on the potential of virtual reality (VR). Rather than asking participants to imagine themselves in a specific situation, VR perceptually immerses them in it. We hypothesized that experiencing a scenario in VR would increase feelings of being "present" in the situation, and add to perceived realism compared to the written equivalent. This, in turn, was expected to trigger stronger emotional experiences influencing subsequent behavioral intentions. Methods: In an experiment, participants (N = 153), visitors of a large music festival, either read a "bar fight" scenario or experienced the scenario in VR. Following the scenario, they were presented a series of questions including intention to aggress, perceived risk, anticipated shame/guilt, presence, perceived realism, and anger. Analyses were conducted using analysis of variance, stepwise regression, and mediation analysis using nonparametric bootstrapping. Results: In line with expectations, the results indicate significant differences between conditions with the VR scenario triggering stronger presence, higher realism, and higher intention to aggress. Importantly, presence and anger mediated the relation between condition and intention to aggress. Conclusions: We show that the VR scenario method may provide benefits over written scenarios for the study of criminal decision-making. Implications are discussed. [ABSTRACT FROM AUTHOR]

In this article we describe a new method, the Virtual Enactment Method (VEM), to enhance offender recall and motivation to disclose information by having burglars reflect on their experience while committing a crime in a simulated virtual environment. Participants, a sample of 61 incarcerated burglars, 'thought aloud' whilst undertaking a virtual burglary. Following the 'virtual' burglary, emerging themes were expanded upon in an interview. We show that the simulated environment effectively reinstates the criminogenic event, increases engagement, enhances recall and encourages participants to talk more openly about their experiences, skills and knowledge.

Objectives: This article explores the potential of virtual reality (VR) to study burglary by measuring user responses on the subjective, physiological, and behavioral levels. Furthermore, it examines the influence of individual dispositions, such as sensation seeking and self-control, on behavior during a virtual burglary event. Methods: Participants, male university undergraduates (N = 77), could freely move around a virtual neighborhood wearing a VR headset and using a game controller and were instructed to burgle one of the houses in the neighborhood. Participant movement, items stolen from the house, and heart rate (HR) were recorded throughout the burglary event. Individual dispositions were measured before, and subjective user responses were measured after, the event. Additionally, we experimentally varied whether there was an alarm sounding and participants' beliefs about the chance of getting caught (deterrence). Results: Participants reacted subjectively to the burglary event by reporting high levels of presence in the virtual environment (VE) and physiologically by showing increased HRs. In terms of behavior, high deterrence resulted in fewer items being stolen and a shorter burglary. Furthermore, sensation seekers stole more valuable items, while participants high in conscientiousness stole fewer items. Conclusions: The results suggest that VEs have substantial potential for studying criminal behavior. [ABSTRACT FROM AUTHOR]

This study examined user engagement with ZeroPhobia, a self-guided app-based virtual reality (VR) Cognitive Behavior Therapy for acrophobia symptoms using cardboard VR viewers. Dutch acrophobic adults (n = 96) completed assessments at baseline and immediately following treatment. Primary outcome measures were the Acrophobia Questionnaire (AQ) and the Igroup Presence Questionnaire (IPQ). Usage data consisted of number of VR sessions practiced, practice time, and fear ratings directly after practicing. Results show that of the 66 participants who played at least one level, the majority continued to finish all levels, spending on average 24.4 min in VR. Self-reported fear consistently decreased between the start and finish of levels. Post-test AQ scores depended quadratically on time spent in VR. Higher pre-test AQ scores were significantly associated with subjective anxiety after the first level and a reduction of post-test AQ scores, but not with number of sessions, suggesting it might be more beneficial to play one level for a longer time period instead of practicing many VR levels. Results also show an optimum exposure level at which increasing practice time does not result in increased benefit. Self-guided VR acrophobia treatment is effective and leads to consistent reductions in self-reported anxiety both between levels and after treatment. Most participants progressed effectively to the highest self-exposure level, despite the absence of a therapist. [ABSTRACT FROM AUTHOR]

High levels of Fear of Crime (FOC) are associated with people engaging with their community less, lower use of public spaces, and a general sense of overall anxiety. In short, such fear may reduce the livability of an area. The primary goal of this research was to examine the potential consequences of environmental interventions intended to reduce crime on FOC and perceived livability of the area. Using immersive Virtual Reality (VR) technology, in two studies we examined how environmental interventions in residential neighborhoods influence FOC. In Study 1, we examined how motion-activated, dynamic street lighting and sound may decrease FOC. In Study 2, we applied an adapted 'watching eyes' intervention and examined how it may inadvertently increase FOC in a neighborhood. In Study 1 the intervention did not affect feelings of safety. In Study 2, the 'watching eyes' intervention indirectly increased FOC via feelings of being watched. In the Discussion, we highlight the importance of better understanding the boundary conditions of such environmental interventions. • In two Virtual Reality Experiments we examined how environmental interventions influence Fear of Crime. • In study 1, manipulated lighting and sound did not influence Fear of crime. • In study 2, a Watching-eyes intervention indirectly increased Fear of Crime via feelings of being watched. • Watching-eyes interventions aimed at reducing crime may indirectly increase the Fear of Crime. • Researchers should examine the boundary conditions and potential unintended consequences of environmental interventions.
